+0.49 - Tues 13 June 2003
+
+- Return immediately for "sleep 10 & echo foo", rather than waiting
+  for the sleep to return (pointed out by Rob Landley)
+
+- Added -P pidfile argument to the server (from Swen Schillig)
+
+- Compile fixes, make sure that all variable definitions are at the start
+  of a scope.
+
+- Use $HOME in preference to that from /etc/passwd, so that it
+  dbclient can still work on systems with a broken setup.
+
+- Add -N dbclient option for "no command"
+
+- Add -f dbclient option for "background after auth"
+
+- Try to finally fix ss_family compilation problems
+
+0.48.1 - Sat 11 March 2006
+
+- Compile fix for scp
+
+0.48 - Thurs 9 March 2006
+
+- Check that the circular buffer is properly empty before
+  closing a channel, which could cause truncated transfers
+  (thanks to Tomas Vanek for helping track it down)
+
+- Implement per-IP pre-authentication connection limits 
+  (after some poking from Pablo Fernandez)
+
+- Exit gracefully if trying to connect to as SSH v1 server 
+  (reported by Rushi Lala)
+
+- Only read /dev/random once at startup when in non-inetd mode
+
+- Allow ctrl-c to close a dbclient password prompt (may
+  still have to press enter on some platforms)
+
+- Merged in uClinux patch for inetd mode
+
+- Updated to scp from OpenSSH 4.3p2 - fixes a security issue
+  where use of system() could cause users to execute arbitrary
+  code through malformed filenames, ref CVE-2006-0225
+
+0.47 - Thurs Dec 8 2005
+
+- SECURITY: fix for buffer allocation error in server code, could potentially
+  allow authenticated users to gain elevated privileges. All multi-user systems
+  running the server should upgrade (or apply the patch available on the
+  Dropbear webpage).
+
+- Fix channel handling code so that redirecting to /dev/null doesn't use
+  100% CPU.
+
+- Turn on zlib compression for dbclient.
+
+- Set "low delay" TOS bit, can significantly improve interactivity
+  over some links.
+
+- Added client keyboard-interactive mode support, allows operation with
+  newer OpenSSH servers in default config.
+
+- Log when pubkey auth fails because of bad ~/.ssh/authorized_keys permissions
+
+- Improve logging of assertions
+
+- Added aes-256 cipher and sha1-96 hmac.
+
+- Fix twofish so that it actually works.
+
+- Improve PAM prompt comparison.
+
+- Added -g (dbclient) and -a (dropbear server) options to allow
+  connections to listening forwarded ports from remote machines.
+
+- Various other minor fixes
+
+- Compile fixes for glibc 2.1 (ss_family vs __ss_family) and NetBSD
+  (netinet/in_systm.h needs to be included).
+
 0.46 - Sat July 9 2005
 
 - Fix long-standing bug which caused connections to be closed if an ssh-agent

+Entropy from /dev/random
+------------------------
+
+The dropbear binary package is configured at compile time to read
+entropy from /dev/random. If /dev/random on a system blocks when
+reading data from it, client logins may be delayed until the client
+times out. The dropbear server writes a notice to the logs when it
+sees /dev/random blocking.  A workaround for such systems is to
+re-compile the package with DROPBEAR_RANDOM_DEV set to /dev/urandom
+in options.h.

+December 16th, 2006
+v1.16 -- Brian Gladman pointed out that a recent change to GCM broke how the IV was handled.  Currently the code complies against his test vectors
+         so the code should be considered frozen now.
+      -- Trevor from Cryptography Research Inc. submitted patches to convert the ECC code to be generic allowing curve parameters to be submitted
+         at runtime.  
+      -- Fixed various doxygen comments
+      -- Added UTF8 support to the ASN1 code
+      -- Fixed STOREXXH macros for x86 platforms (Fix found at Elliptic Inc.)
+      -- Added makefile.unix which is BSD compatible, you have to manually tweak it since well I don't use it normally
+      -- removed a few lingering memcpy's
+      -- Fixed memory free errors in ecc_sign_hash() that can arise if the mp_init_multi() fails
+      -- Fixed incorrect return value in pkcs_1_pss_decode() which would correctly set res to 0 (indicating an incorrect signature) but 
+         would return CRYPT_OK to the caller
+      -- ltc_ecc_mulmod() could leak memory if mp_init(&mu) failed, fixed.  Would you believe that ltc_ecc_mulmod_timing() had the same
+         bug?  Also fixed.  :-)
+      -- Added Shamir's trick to the ECC side (defined as LTC_ECC_SHAMIR, enabled by default), gets ~1.34x to ~1.40x faster ECC verifications
+      -- Added Brian's vector #46 to the GCM code.  It catches the ctr counter error from v1.15.  Originally I was going to add all of his vectors,
+         but they're not as easy to parse and I got a lot of other things to do.  Regression!
+      -- Various other small fixes to the ECC code to clean up error handling (I think most of that was from the move in 1.06 to the plugins)
+         All of the errors were in cleaning up from heap failures.  So they were not likely to be triggered in normal usage
+         Made similar fixes to the RSA and DSA code (my bad)
+      -- Cryptography Research Inc. contributed a bunch of fixes to silence warnings (with MSVC) w.r.t. assigned data to unsigned char types.
+      -- Martin Marko suggested some fixes to make the RNG build with WinCE.
+      -- Updates to the manual for print (some fixes thanks to Martin Marko)
+      
+
+November 17th, 2006
+v1.15 -- Andreas Lange found that if sha256_init DID fail in fortuna it wouldn't clean up the state correctly.  Thanks.
+         Fortunately sha256_init cannot fail (as of v1.14) :-)
+      -- Andreas Lange contributed RMD-256 and RMD-320 code.
+      -- Removed mutex locks from fortuna_import as they create a deadlock and aren't required anyways [Avi Zelmanovich]
+      -- Added LTC_NO_PROTOTYPES to avoid prototyping functions like memset/memcpy.  Required for fans of GCC 3.3.x
+      -- David Eder caught a off by one overrun bug in pmac_done() which can be exploited if your output tag buffer is 
+         smaller than the block size of the cipher, e.g. if you have a 4-byte buffer and you tell pmac_done that you want
+         a 4-byte TAG it will store 4 bytes but return an outlen of 5.
+      -- Added signatures to the ECC and RSA benchmarks
+      -- Added LTC_PROFILE to run the PK tests only once in the timing demo (so you can capture events properly)
+      -- Andreas contributed PKCS #1 v1.5 code that merged cleanly with the existing PKCS code.  w00t.
+         (update: I had to fix it to include the digestInfo and what not.  Bad Andreas, bad! hehehe)
+      -- Fixed a signed variable error in gcm_process() (hard to trigger bug fortunately)
+      -- Removed all memcmp/memset/memcpy from the source (replaced with X macros)
+      -- Renamed macros HMAC/OMAC/PMAC to have a LTC_ prefix.  If you pass these on the command line please update your makefiles
+      -- Added XCBC-MAC support [RFC 3566]
+      -- fixed LOAD32H and LOAD64H to stop putting out that darn warning :-)
+      -- Added the Korean SEED block cipher [RFC 4269]
+      -- Added LTC_VALGRIND define which makes SOBER-128 and RC4 a pure PRNG (and not a stream cipher).  Useful if you use 
+         Valgrind to debug your code (reported by Andreas Lange)
+      -- Made SOBER-128 more portable by removing the ASCII key in the test function (my bad, sorry).
+      -- Martin Mocko pointed out that if you have no PRNGs defined the lib won't build.  Fixed, also fixed for if you have no
+         hashes defined.
+      -- Sped up F8 mode with LTC_FAST
+      -- Made CTR mode RFC 3686 compliant (increment counter first), to enable, OR the value LTC_CTR_RFC3686 to the "mode"
+         parameter you pass to ctr_start(), otherwise it will be LTC compliant (e.g. encrypt then increment)
+      -- Added ctr_test() to test CTR mode against RFC 3686
+      -- Added crypt_fsa() ... O_o
+      -- Fixed LTC_ECC_TIMING_RESISTANT so it once again builds properly (pt add/dbl are through the plugin now)
+      -- Added ANSI X9.63 (sec 4.3.6) import/export of public keys (cannot export to compressed formats but will import 
+         hybrid compressed)
+      -- Added SECP curves for 112, 128, and 160 bits (only the 'r1' curves)
+      -- Added 3GPP-F9 MAC (thanks to Greg Rose for the test vectors)
+      -- Added the KASUMI block cipher
+      -- Added F9/XCBC/OMAC callbacks to the cipher plugin
+      -- Added RSA PKCS #1 v1.5 signature/encrypt tests to rsa_test.c
+      -- Fix to yarrow_test() to not call yarrow_done() which is invalid in that context (thanks Valgrind)
+      -- Christophe Devine pointed out that Anubis would fail on various 64-bit UNIX boxes when "x>>24" was used as an index, we needed 
+         to mask it with 0xFF.  Thanks.  Fixed.
+
+August 0x1E, 0x07D6
+v1.14 -- Renamed the chaining mode macros from XXX to LTC_XXX_MODE.  Should help avoid polluting the macro name space.
+      -- clean up of SHA-256
+      -- Chris Colman pointed out that der_decode_sequence_* allows LTC_ASN1_SETOF to accept SEQUENCEs and vice versa.
+         Decoder [non-flexi decoder that is] is more strict now and requires a match.
+      -- Steffen Jaeckel pointed out a typo in the user manual (re: rsa_exptmod).  Fixed.  This disproves the notion that
+         nobody reads it.  :-)
+      -- Made GCM a bit more portable w.r.t. handling the CTR IV (e.g. & with 255)
+      -- Add LTC_VERBOSE if you really want to see what test is doing :-)
+      -- Added SSE2 support to GCM [use GCM_TABLES_SSE2 to enable], shaves 2 cycles per byte on Opteron processors
+         Shaved 4 cycles on a Prescott (Intel P4)
+         Requires you align your gcm_state on a 16 byte boundary, see gcm_memory() for more info
+      -- Added missing prototype for f8_test_mode()
+      -- two fixes to CCM for corner cases [L+noncelen > 15] and fixing the CTR pad to encrypt the CBC-MAC tag
+      -- Franz Glasner pointed out the ARGTYPE=4 is not actually valid.  Fixed.
+      -- Fixed bug in f8_start() if your key < saltkey unspecified behaviour occurs.  :-(
+      -- Documented F8 mode.  Yeah, because you read the manual.  
+      -- Minor updates to the technotes.
+
+
+June 17th, 2006
+v1.13 -- Fixed to fortuna_start() to clean up state if an error occurs.  Not really useful at this stage (sha256 can't fail) but useful
+         if I ever make fortuna pluggable
+      -- Mike Marin submitted a whole bunch of patches for fixing up the libs on traditional UNIX platforms.  Go AIX!  Thanks!
+      -- One of bugs found in the multi demo highlights that at least with gcc you need to pass integers with a UL prefix to ensure
+         they're unsigned long
+      -- Updated the FP ECC code to use affine points.  It's teh fast.
+      -- Made it so many functions which return CRYPT_BUFFER_OVERFLOW now also indicate the required buffer size, note that not all functions
+         do this (most do though).
+      -- Added F8 chaining mode.  It's super neato.
+
+May 29th, 2006
+v1.12 -- Fixed OID encoder/decoder/length to properly handle the first two parts of an OID, matches 2002 X.690 now.
+      -- [Wesley Shields] Allows both GMP/LTM and TFM to be defined now.  
+      -- [Wesley Shields] GMP pluggin is cleaner now and doesn't use deprecated symbols. Yipee
+      -- Added count_lsb_bits to get the number of leading LSB zero bits there are.
+      -- Fixed a bug in the INTEGER encoders for values of -(256**k)/2
+      -- Added BOOLEAN type to ASN.1 thingy-ma-do-hicky
+      -- Testprof doesn't strictly require GMP ... oops [Nils Durner]
+      -- Added LTC_CALL and LTC_EXPORT macros in tomcrypt_cfg.h to support various calling and linker conventions
+         (Thanks to John Kirk from Demonware)
+      -- In what has to be the best thing since sliced bread I bring you MECC_FP which is the fixed point
+         ECC point multiplier.  It's fast, it's sexy and what's more it's hella fast [did I mention it's fast?]
+         You can tune it somewhat with FP_LUT (default to 8) for look-up width.
+         Read section 8.2 of the manual for more info.
+         It is disabled by default, you'll have to build LTC with it defined to get it.  
+      -- Fixed bug in ecc_test.c (from testprof) to include the 521 [not 512] bit curve.  :-)
+
+April 4th, 2006
+v1.11 -- Removed printf's from lrw_test ... whoops
+      -- lrw_process now checks the return of the cipher ecb encrypt/decrypt calls
+      -- lrw_start was not using num_rounds ...
+      -- Adam Miller reported a bug in the flexi decoder with elements past the end of a sequence.  Fixed.
+      -- Bruce Guenter suggested I use --tag=CC for libtool builds where the compiler may think it's C++.  (I applied this to LTM and TFM)
+      -- Optimized the ECC for TFM a bit by removing the useless "if" statements (most TFM functions don't return error codes)
+         Actually shaved a good chunk of time off and made the code smaller.  By default with TFM the stock LTC point add/dbl functions 
+         will be totally omitted (ECC-256 make key times on a Prescott for old vs. new are 11.03M vs. 9.59M cycles)
+      -- added missing CVS tags to ltc_ecc_mulmod.c
+      -- corrected typo in tomcrypt_cfg.h about what the file has been called 
+      -- corrected my address in the user manual.  A "bit" out of date.
+      -- added lrw_gen to tv_gen
+      -- added GMP plugin, only tested on a AMD64 and x86_32 Gentoo Linux box so be aware
+      -- made testme.sh runs diff case insensitivityly [whatever...] cuz GMP outputs lowercase satan text
+      -- added LDFLAGS to the makefile to allow cross porting linking options
+      -- added lrw_test() to the header file ... whoops
+      -- changed libtomcrypt.org to libtomcrypt.com .... mumble mumble
+      -- Updates to detect __STRICT_ANSI__ which is defined in --std=c99 modes (note -ansi is not supported as it lacks long long) so you can
+         build LTC out of the box with c99 (note: it'll be slower as there is no asm in this case)
+      -- Updated pelican.c and aes_tab.c to undef tables not-required.  The tables are static so both AES and Pelican MAC would have copies.  Save a few KB in the final binary.
+      -- Added LTC_NO_FAST to the makefile.icc to compensate for the fact ICC v9 can't handle it (Pelican MAC fails for instance)
+
+February 11th, 2006
+v1.10 -- Free ecb/cbc/ctr/lrw structures in timing code by calling the "done" function
+      -- fixed bug in lrw_process() which would always use the slow update ...
+      -- vastly sped up gcm_gf_mult() when LTC_FAST is defined.  This speeds up LRW and GCM state creation, useful for servers with GCM
+      -- Removed NLS since there are some attacks against it.  
+      -- fixed memory leak in rsa_import reported by John Kuhns
+      ++ re-released as the rsa fix was incorrect (bad John bad ... hehehe) and I missed some NULLs in the static descriptor entry for ciphers 
+
+January 26th, 2006
+v1.09 -- Added missing doxygen comments to some of the ASN.1 routines
+      -- Added "easy button" define LTC_EASY and LTC will build with a subset of all the algos.  Reduces build times for typical
+         configurations.  Tunable [see tomcrypt_custom.h]
+      -- Added some error detection to reg_algs() of the testprof.a library to detect when the PRNG is not setup correctly (took me 10 mins to figure out, PITA!)
+      -- Similar fixes to timing demo (MD5 not defined when EASY is defined)
+      -- Added the NLS enc+mac stream cipher from QUALCOMM, disabled for this release, waiting on test vectors
+      -- Finally added an auto-update script for the makefiles.  So when I add new files/dirs it can automatically fix up the makefiles [all four of them...]
+      -- Added LRW to the list of cipher modes supported
+      -- cleaned up ciphers definitions to remove cbc/cfb/ofb/ctr/etc from the namespace when not used.
+
+November 24th, 2005
+v1.08 -- Added SET and SET OF support to the ASN.1 side
+      -- Fixed up X macros, added QSORT to the mix [thanks SET/SETOF]
+      -- Added XMEMCMP to the list of X macros
+      -- In der_decode_sequence() the SHORT_INTEGER type was not being handled correctly [oddly enough it worked just enough to make RSA work ... go figure!]
+      -- Fixed bug in math descriptors where if you hadn't defined MECC (ECC support) you would get linker errors
+      -- Added RSA accelerators to the math descriptors to make it possible to not include the stock routines if you supply your own.
+      -- dsa_decrypt_key() was erroneously dependent on MECC not MDSA ... whoops
+      -- Moved DSA size limits to tomcrypt_pk.h so they're defined with LTC_NO_PK+MDSA
+      -- cleaned up tomcrypt_custom.h to make customizable PK easier (and also cleaned up the error traps so they're correctly reported)
+
+November 18th, 2005
+v1.07 -- Craig Schlenter pointed out the "encrypt" demo doesn't call ctr_start() correctly.  That's because as of a few releases ago
+         I added support to set the mode of the counter at init time
+      -- Fixed some "testprof" make issues
+      -- Added RSA keygen to the math descriptors
+      -- Fixed install_test target ... oops
+      -- made the "ranlib" program renamable useful for cross-compiling
+      -- Made the cipher accelerators return error codes.  :-)
+      -- Made CCM accept a pre-scheduled key to speed it up if you use the same key for multiple packets
+      -- Added "Katja" public key crypto.  It's based on the recent N = p^2q work by Katja.  I added OAEP padding
+         to it.  Note this code has been disabled not because it doesn't work but because it hasn't been thoroughly
+         analyzed.   It does carry some advantages over RSA (slightly smaller public key, faster decrypt) but also
+         some annoying "setup" issues like the primes are smaller which makes ECM factoring more plausible.
+      -- Made makefile accept a NODOCS flag to disable the requirement of tetex to install LTC for you no tetex people... all 3 of ya  :-)
+      -- Cleaned up rsa_export() since "zero" was handled with a SHORT_INTEGER
+      -- Cleaned up the LIBTEST_S definitions in both GNU makefiles.  A few minor touchups as well.
+      -- Made the cipher ecb encrypt/decrypt return an int as well, changed ALL dependent code to check for this.  
+      -- der_decode_choice() would fail to mark a NULL as "used" when decoding.  Fixed
+      -- ecc_decrypt_key() now uses find_hash_oid() to clean up the code ;-)
+      -- Added mp_neg() to the math descriptors.
+      -- Swapped arguments for the pkcs_1_mgf1() function so the hash_idx is the first param (to be more consistent)
+      -- Made the math descriptors buildable when RSA has been undefined
+      -- ECC timing demo now capable of detecting which curves have been defined
+      -- Refactored the ECC code so it's easier to maintain.  (note: the form of this code hasn't really changed since I first added ECC ... :-/)
+      -- Updated the documentation w.r.t. ECC and the accelerators to keep it current
+      -- Fixed bug in ltc_init_multi() which would fail to free all allocated memory on error.
+      -- Fixed bug in ecc_decrypt_key() which could possibly lead to overflows (if MAXBLOCKSIZE > ECC_BUF_SIZE and you have a hash that emits MAXBLOCKSIZE bytes)
+      -- Added encrypt/decrypt to the DSA side (basically DH with DSA parameters)
+      -- Updated makefiles to remove references to the old DH object files and the ecc_sys.o crap ... clean code ahead!
+      -- ecc_import() now checks if the point it reads in lies on the curve (to prevent degenerative points from being used)
+      -- ECC code now ALWAYS uses the accelerator interface.  This allows people who use the accelerators to not have the stock
+         ECC point add/dbl/mul code linked in.  Yeah space savings! Rah Rah Rah.
+      -- Added LTC_MUTEX_* support to Yarrow and Fortuna allowing you to use respective prng_state as a global PRNG state [e.g. thread-safe] if you define one of the LTC_* defines at
+         build time (e.g. LTC_PTHREAD == pthreads)
+      -- Added PPC32 support to the rotate macros (tested on an IBM PPC 405) and LTC_FAST macros (it aint fast but it's faster than stock)
+      -- Added ltc_mp checks in all *_make_key() and *_import() which will help catch newbs who don't register their bignum first :-)
+      -- the UTCTIME type was missing from der_length_sequence() [oops, oh like you've never done that]
+      -- the main makefile allows you to rename the make command [e.g. MAKE=gmake gmake install] so you can build LTC on platforms where the default make command sucks [e.g. BSD]
+      -- Added DER flexi decoder which allows the decoding of arbitrary DER encoded packets without knowing
+         their structure in advance (thanks to MSVC for finding 3 bugs in it just prior to release! ... don't ask)
+
+August 1st, 2005
+v1.06 -- Fixed rand_prime() to accept negative inputs as a signal for BBS primes. [Fredrik Olsson]
+      -- Added fourth ARGCHK type which outputs to stderr and continues.  Useful if you trap sigsegv.   [Valient Gough]
+      -- Removed the DH code from the tree
+      -- Made the ECC code fully public (you can access ecc_mulmod directly now) useful for debuging
+      -- Added ecc test to tv_gen
+      -- Added hmac callback to hash descriptors.
+      -- Fixed two doxy comment errors in the UTCTIME functions
+      -- rsa_import() can now read OpenSSL format DER public keys as well as the PKCS #1 RSAPublicKey format.
+         Note that rsa_export()  **ONLY** writes PKCS #1 formats
+      -- Changed MIN/MAX to only define if not already present.  -- Kirk J from Demonware ... 
+      -- Ported tv_gen to new framework (and yes, I made ecc vectors BEFORE changing the API and YES they match now :-))
+      -- ported testing scripts to support pluggable math.  yipee!
+      -- Wrote a TFM descriptor ... yipee
+      -- Cleaned up LTC_FAST in CBC mode a bit 
+      -- Merged in patches from Michael Brown for the sparc/sparc64 targets
+      -- Added find_hash_oid() to search for a hash by its OID
+      -- Cleaned up a few stray CLEAN_STACKs that should have been LTC_CLEAN_STACK
+      -- Added timing resistant ECC, enable by defining LTC_ECC_TIMING_RESISTANT then use ECC API as normal 
+      -- Updated the ECC documentation as it was a bit out of date
+
+June 27th, 2005
+v1.05
+      -- Added Technote #6 which covers the current PK compliance.  
+      -- Fixed buffer overflow in OAEP decoder
+      -- Added CHOICE to the list of ASN.1 types
+      -- Added UTCTIME to the list of ASN.1 types
+      -- Added MUTEX locks around descriptor table functions [but not on the functions that are dependent on them]
+         All functions call *_is_valid() before using a descriptor index which means the respective table must be unlocked before 
+         it can be accessed.  However, during the operation [e.g. CCM] if the descriptor has been altered the results will be 
+         undefined.  
+      -- Minor updates to the manual to reflect recent changes
+      -- Added a catch to for an error that should never come up in rsa_exptmod().  Just being thorough.
+
+June 15th, 2005
+v1.04
+      -- Fixed off by one [bit] error in dsa_make_key() it was too high by one bit [not a security problem just inconsistent]
+      -- ECC-224 curve was wrong [it was an ok curve just not NIST, so no security flaw just interoperability].
+      -- Removed point compression since it slows down ECC ops to save a measly couple bytes.
+         This makes the ecc export format incompatible with 1.03 [it shouldn't change in the future]
+      -- Removed ECC-160 from timing and added the other curves
+
+June 9th, 2005
+v1.03
+      -- Users may want to note that on a P4/GCC3.4 platform "-fno-regmove" greatly accelerates the ciphers/hashes.
+      --------------------------------------------------------------------------------------------------------------
+      -- Made it install the testing library in the icc/static makefiles
+      -- Found bug in ccm_memory.c which would fail to compile when LTC_CLEAN_STACK was enabled
+      -- Simon Johnson proposed I do a fully automated test suite.  Hence "testme.sh" was born
+      -- Added LTC_NO_TEST which forces test vectors off (regardless of what tomcrypt_custom.h has)
+      -- Added LTC_NO_TABLES which disables large tables (where possible, regardless of what tomcrypt_custom.h has)
+      -- New test script found a bug in twofish.c when TABLES was disabled.  Yeah testing!
+      -- Added a LTC_FAST specific test to the testing software.
+      -- Updated test driver to actually halt on errors and just print them out (useful for say... automated testing...)
+      -- Added bounds checking to Pelican MAC
+      -- Added BIT and OCTET STRING to the ASN.1 side of things.  
+      -- Pekka Riikonen pointed out that my ctr_start() function should accept the counter mode. 
+      -- Cleaned up warnings in testprof
+      -- Removed redundant mu and point mapping in ecc_verify_hash() so it should be a bit faster now
+      -- Pekka pointed out that the AES key structure was using 32 bytes more than it ought to.
+      -- Added quick defines to remove entire classes of algorithms.  This makes it easier if you want to build with just 
+         one algorithm (say AES or SHA-256).  Defines are LTC_NO_CIPHERS, LTC_NO_MODES, LTC_NO_HASHES, LTC_NO_MACS,
+         LTC_NO_PRNGS, LTC_NO_PK, LTC_NO_PKCS
+      -- As part of the move for ECC to X9.62 I've changed the signature algorithm to EC DSA.  No API changes.
+      -- Pekka helped me clean up the PKCS #1 v2.1 [OAEP/PSS] code
+      -- Wrote new DER SEQUENCE coder/decoder
+      -- RSA, DSA and ECDSA now use the DER SEQUENCE code (saves a lot of code!)
+      -- DSA output is now a DER SEQUENCE (so not compatible with previous releases).  
+      -- Added Technote #5 which shows how to build LTC on an AMD64 to have a variety of algorithms in only ~80KB of code.
+      -- Changed temp variable in LOAD/STORE macros to "ulong32" for 32-bit ops.  Makes it safer on Big endian platforms
+      -- Added INSTALL_GROUP and INSTALL_USER which you can specify on the build to override the default USER/GROUP the library 
+         is to be installed as
+      -- Removed "testprof" from the default build.  
+      -- Added IA5, NULL and Object Identifier to the list of ASN.1 DER supported types
+      -- The "no_oops" target (part of zipup) now scans for non-cvs files.  This helps prevent temp/scratch files from appearing in releases ;-)
+      -- Added DERs for missing hashes, but just the OID not the PKCS #1 v1.5 additions. 
+      -- Removed PKCS #1 v1.5 from the tree since it's taking up space and you ought to use v2.1 anyways
+      -- Kevin Kenny pointed out a few stray // comments
+      -- INTEGER code properly supports negatives and zero padding [Pekka!]
+      -- Sorted asn1/der/ directory ... less of a mess now ;-)
+      -- Added PRINTABLE STRING type
+      -- Removed ECC-160 as it wasn't a standard curve
+      -- Made ecc_shared_secret() ANSI X9.63 compliant
+      -- Changed "printf" to "fprintf(stderr, " in the testbench... ;-)
+      -- Optimized the GCM table creation.  On 1KB packets [with key switching] the new GCM is 12.7x faster than before.
+      -- Changed OID representation for hashes to be just a list of unsigned longs (so you can compare against them nicely after decoding a sequence)
+      -- ECC code now uses Montgomery reduction ... it's even faster [ECC-256 make key down from 37.4M to 4.6M cycles on an Athlon64]
+      -- Added SHORT_INTEGER so users can easily store DER encoded INTEGER types without using the bignum math library
+      -- Fixed OMAC code so that with LTC_FAST it doesn't require that LTC_FAST_TYPE divides 16 [it has to divide the block size instead]
+      -- ECC key export is now a simple [and documented] SEQUENCE, the "encrypt_key" also uses a new SEQUENCE format.
+      -- Thanks goes to the following testers
+            Michael Brown             - Solaris 10/uSPARCII
+            Richard Outerbridge       - MacOS

+
+April 19th, 2005
+v1.02
+      -- Added LTC_TEST support to gcm_test()
+      -- "pt/ct" can now be NULL in gcm_process() if you are processing zero bytes
+      -- Optimized GCM by removing the "double copy" handling of the plaintext/aad
+      -- Richard Outerbridge pointed out that x86_prof won't build on MACOS and that the manual 
+         erroneously refers to "mycrypt" all over the place.  Fixed.
+
+April 17th, 2005
+v1.01
+       ** Secure Science Corporation has supported this release cycle by sponsoring the development time taken.  Their 
+          continuing support of this project has helped me maintain a steady pace in order to keep LibTomCrypt up to date,
+          stable and more efficient.
+       -----------------------------------------------------------------------------------------------------
+       -- Updated base64_decode.c so if there are more than 3 '=' signs it would stop parsing
+       -- Merged in latest mpi that fixed a few bugs here and there
+       -- Updated OAEP encoder/decoder to catch when the hash output is too large
+          Cleaned up PSS code too
+       -- Andy Bontoft fixed a bug in my demos/tests/makefile.msvc ... seems "dsa_test.c" isn't an object
+          afterall.  Thanks.
+       -- Made invalid ECC key sizes (configuration) not hard fault the program (it returns an error code now)
+       -- SAFER has been re-enabled after I was pointed to http://www.ciphersbyritter.com/NEWS2/95032301.HTM
+          [Mark Kotiaho]
+       -- Added CCM mode to the encauth list (now has EAX, OCB and CCM, c'est un treo magnifique!)
+       -- Added missing ASN.1 header to the RSA keys ... oops... now the rsa_export/import are FULLY compatible
+          with other libs like OpenSSL (comment:  Test vectors would go a long way RSA...)
+       -- Manually merged in fix to the prime_random_ex() LTM function that ensures the 2nd MSB is set properly.  Now
+          When you say "I want a 1024/8 byte RSA key" the MSB bit of the modulus is set as expected.  Note I generally 
+          don't view this as a "huge issue" but it's just one less nit to worry about. [Bryan Klisch]
+       -- A new CVS has been setup on my Athlon64 box... if you want developer access send me an email (and at this point the email would have to be awesome).
+       -- Updated API for ECB and CBC shell code.  Now can process N whole blocks in one call (like $DEITY intended)
+       -- Introduced a new "hardware accel" framework that can be used to speed up cipher ECB, CBC and CTR mode
+          calls.  Later on dependent code (e.g. OMAC, CCM) will be re-written to use the generic cbc/ctr functions.  But now
+          if you [say] call ctr_encrypt() with a cipher descriptor that has hardware CTR it will automatically
+          be used (e.g. no code rewrites)
+       -- Now ships with 20% more love.
+       -- x86_prof now uses ECB shell code (hint: accelerators) and outputs cycles per BLOCK not byte.  This will make it a bit 
+          easier to compare hardware vs. software cipher implementations.  It also emits timings for CBC and CTR modes
+       -- [Peter LaDow] fixed a typo w.r.t. XREALLOC macro (spelling counts kids!)
+       -- Fixed bug with __x86_64__ where ROL64/ROR64 with LTC_NO_ROLC would be the 32-bit versions instead...
+       -- Shipping with preliminary GCM code (disabled).  It's buggy (stack overflow hidden somewhere).  If anyone can spot it let me know.
+       -- Added Pelican MAC [it's an AES based fast MAC] to the list of supported MACs
+       -- Added LTC_FAST [and you can disable by defining LTC_NO_FAST] so that CBC and CTR mode XOR whole words [e.g. 32 or 64 bits] at a time
+          instead of one byte.  On my AMD64 this reduced the overhead for AES-128-CBC from 4.56 cycles/byte to around 1 cycle/byte.  This requires
+          that you either allow unaligned read/writes [e.g. x86_32/x86_64] or align all your data.  It won't go out of it's way to ensure 
+          aligned access.  Only enabled for x86_* platforms by default since they allow unaligned read/writes.
+       -- Added LTC_FAST support to PMAC (drops the cycle/byte by about 9 cycles on my AMD64) [note: I later rewrote this prior to release]
+       -- Updated "profiled" target to work with the new directory layout
+       -- Added [demo only] optimized RC5-CTR code to x86_prof demo to show off how to make an accelerator
+          [This has been removed prior to release... It may re-appear later]
+       -- Added CCM acelerator callbacks to the list [now supports ECB, CTR, CBC and now CCM].
+       -- Added chapter to manual about accelerators (you know you want it)
+       -- Added "bswap" optimizations to x86 LOAD/STORE with big endian.  Can be disabled by defining LTC_NO_BSWAP
+       -- LTC_NO_ASM is now the official "disable all non-portable stuff" macro.  When defined it will make the code endian-neutral,
+          disable any form of ASM and disable LTC_FAST load/stores.  Essentially build the library with this defined if you're having
+          trouble building the library (old GCCs for instance dislike the ROLc macro)
+       -- Added tomcrypt_mac.h and moved MAC/encMAC functions from tomcrypt_hash.h into it
+       -- Added "done" function to ciphers and the five chaining modes [and things like omac/pmac/etc]
+       -- Changed install group to "wheel" from "root".
+       -- Replaced // comments with /**/ so it will build on older UNIX-like platforms
+       -- x86_prof builds and runs with IntelCC fine now 
+       -- Added "stest" build to intel CC to test static linked from within the dir (so you don't have to install to test)
+       -- Moved testing/benchmark into testprof directory and build it as part of the build.  Now you can link against libtomcrypt_prof.a to get 
+          testing info (hint: hardware developers ;-) )
+       -- Added CCM to tv_gen 
+       -- Added demos to MSVC makefile
+       -- Removed -funroll-all-loops from GCC makefile and replaced with -funroll-loops which is a bit more sane (P4 ain't got much cache for the IDATA)
+       -- Fixed GCM prior to release and re-enabled it.  It has not been optimized but it does conform when compiled with optimizations.
+       -- I've since optimized GCM and CCM.  They're close in speed but GCM is more flexible imho (though EAX is more flexible than both)
+       -- For kicks I optimized the ECC code to use projective points.  Gets between 3.21x (Prescott P4) to 4.53x (AMD64) times faster than before at 160-bit keys and the
+          speedup grows as the keysize grows.  Basically removing most practical reasons to "not use the ECC code".  Enjoy.
+       -- Added LTC_FAST support to OMAC/PMAC and doubled it's speed on my amd64 [faster on the P4 too I guess]
+       -- Added GCM to tv_gen
+       -- Removed "makefile.cygwin_dll" as it's not really used by anyone and not worth the effort (hell I hardly maintain the MSVC makefiles ...)
+       -- Updated a few files in the "misc" directory to have correct @file comments for doxygen
+       -- Removed "profile" target since it was slower anyways (go figure...)
+
+December 31st, 2004
+v1.00  
+       -- Added "r,s == 0" check to dsa_verify_hash()
+       -- Added "multi block" helpers for hash, hmac, pmac and omac routines so you can process multiple non-adjacent
+          blocks of data with one call (added demos/multi.c to make sure they work)
+          -- Note these are not documented but they do have doxygen comments inside them
+          -- Also I don't use them in other functions (like pkcs_5_2()) because I didn't have the time.  Job for the new LTC maintainer ;-)
+       -- Added tweaked Anubis test vectors and made it default (undefined ANUBIS_TWEAK to get original Anubis)
+       -- Merged in fix for mp_prime_random_ex() to deal with MSB and LSB "bugs"
+       -- Removed tim_exptmod() completely, updated several RSA functions (notably v15 and the decrypt/verify) so they 
+          don't require a prng now
+       -- This release brought to you by the fine tunes of Macy Gray.  We miss you.
+
+December 23rd, 2004
+v1.00rc1
+       -- Renamed "mycrypt_*" to "tomcrypt_*" to be more specific and professional
+          Now just include "tomcrypt.h" instead of "mycrypt.h" to get LTC ;-)
+       -- Cleaned up makefiles to ensure all headers are correctly installed
+       -- Added "rotate by constant" macros for portable, x86-32 and x86-64
+          You can disable this new code with LTC_NO_ROLC which is useful for older GCCs
+       -- Cleaned up detection of x86-64 so it works for ROL/ROR macros
+       -- Fixed rsa_import() so that it would detect multi-prime RSA keys and error appropriately
+       -- Sorted the source files by category and updated the makefiles appropriately
+       -- Added LTC_DER define so you can trim out DER code if not required
+       -- Fixed up RSA's decrypt functions changing "res" to "stat" to be more in sync
+          with the signature variables nomenclature. (no code change just renamed the arguments)
+       -- Removed all labels starting with __ and replaced with LBL_ to avoid namespace conflicts (Randy Howard)
+       -- Merged in LTM fix to mp_prime_random_ex() which zap'ed the most significant byte if the bit size
+          requested was a multiple of eight.
+       -- Made RSA_TIMING off by default as it's not terribly useful [and likely to be deprecated]
+       -- Renamed SMALL_CODE, CLEAN_STACK and NO_FILE to have a LTC_ prefix to avoid namespace collisions
+          with other programs.  e.g. SMALL_CODE => LTC_SMALL_CODE
+       -- Zed Shaw pointed out that on certain systems installing libs as "root" isn't possible as the super-user
+          is not root.  Now the makefiles allow this to be changed easily.
+       -- Renamed "struct _*_descriptor" to "struct ltc_*_descriptor" to avoid using a leading _
+          Also renamed _ARGCHK to LTC_ARGCHK
+       -- Zed Shaw pointed out that I still defined the prng structs in tomcrypt_prng.h even if they 
+          weren't defined.  This made undef'ing FORTUNA break the build.
+       -- Added LTC_NO_ASM to disable inline asm macros [ROL/ROR/etc]
+       -- Changed RSA decrypt functions to change the output length variable name from "keylen" to "outlen" to make 
+          it more consistent.
+       -- Added the 64-bit Khazad block cipher [NESSIE]
+       -- Added the 128-bit Anubis block cipher [with key support for 128...320 bit keys] [NESSIE]
+       -- Changes to several MAC functions to rename input arguments to more sensible names
+       -- Removed FAST_PK support from dh_sys.c
+       -- Declared deskey() from des.c as static instead of a global
+       -- Added pretty much all practical GCC warning tests to the GCC [related] makefiles.  These additional
+          warnings can easily be disabled for those with older copies of GCC [or even non GNU cc's]
+       -- Added doxygen @ tags to the code...  phew that was a hell of a lot of [repetitive] work
+       -- Also added pre-configured Doxygen script.
+       -- Cleaned up quite a few functions [ciphers, pk, etc] to make the parameters naming style consistent
+          E.g. ciphers keys are called "skey" consistently now.  The input to PK encryption is called "in", etc.
+          These changes require no code changes on the behalf of developers fortunately
+       -- Started a SAFER+ optimizer [does encrypt only] which shaves a good 30 or so cycles/byte on my AMD64
+          at an expense of huge code.  It's in notes/etc/saferp_optimizer.c
+       -- DSA sign/verify now uses DER encoded output/inputs and no LTC style headers.  
+       -- Matt Johnston found a missing semi-colon in mp_exptmod().  Fix has been merged in.  
+
+October 29th, 2004
+v0.99  -- Merged in the latest version of LTM which includes all of the recent bug fixes
+       -- Deprecated LTMSSE and removed it (to be replaced with TFM later on)
+       -- Stefan Arentz pointed out that mp_s_rmap should be extern
+       -- Kristian Gj?steen pointed out that there are typos in the 
+          "test" makefile and minor issues in Yarrow and Sober [just cosmetics really]
+       -- Matthew P. Cashdollar pointed out that "export" is a C++ keyword 
+          so changed the PRNG api to use "pexport" and "pimport"
+       -- Updated "hashsum" demo so it builds ;-)
+       -- Added automatic support for x86-64 (will configure for 64-bit little endian automagically)
+       -- Zhi Chen pointed out a bug in rsa_exptmod which would leak memory on error. 
+       -- Made hash functions "init" return an int.  slight change to API ;-(
+       -- Added "CHC" mode which turns any cipher into a hash the other LTC functions can use
+       -- Added CHC mode stuff to demos such as tv_gen and hashsum
+       -- Added "makefile.shared" which builds and installs shared/static object copies
+          of the library.
+       -- Added DER for bignum support 
+       -- RSA is now fully joy.  rsa_export/rsa_import use PKCS #1 encodings and should be 
+          compatible with other crypto libs that use the format.
+       -- Added support for x86-64 for the ROL/ROR macros 
+       -- Changed the DLL and SO makefiles to optimize for speed, commented SMALL_CODE in
+          mycrypt_custom.h and added -DSMALL_CODE to the default makefile
+       -- Updated primality testing code so it does a minimum of 5 tests [of Miller-Rabin]
+          (AFAIK not a security fix, just warm fuzzies)
+       -- Minor updates to the OMAC code (additional __ARGCHK and removed printf from omac_test... oops!)
+       -- Update build and configuration info which was really really really out of date.  (Chapter 14)
+       ++ Minor update, switch RSA to use the PKCS style CRT
+
+August 6th, 2004
+v0.98  -- Update to hmac_init to free all allocated memory on error
+       -- Update to PRNG API to fix import/export functions of Fortuna and Yarrow
+       -- Added test functions to PRNG api, RC4 now conforms ;-) [was a minor issue]
+       -- Added the SOBER-128 PRNG based off of code donated by Greg Rose.
+       -- Added Tech Note #4 [notes/tech0004.txt] 
+       -- Changed RC4 back [due to request].  It will now XOR the output so you can use it like 
+          a stream cipher easily.
+       -- Update Fortuna's export() to emit a hash of each pool.  This means that the accumulated 
+          entropy that was spread over all the pools isn't entirely lost when you export/import.
+       -- Zhi Chen suggested a comment for rsa_encrypt_key() to let users know [easily] that it was
+          PKCS #1 v2.0 padding.  (updated other rsa_* functions)
+       -- Cleaned up Noekeon to remove unrolling [wasn't required, was messy and actually slower with GCC/ICC]
+       -- Updated RC4 so that when you feed it >256 bytes of entropy it quietly ignores additional
+          bytes.  Also removed the % from the key setup to speed it up a bit.
+       -- Added cipher/hash/prng tests to x86_prof to help catch bugs while testing
+       -- Made the PRNG "done" return int, fixed sprng_done to not require prng* to be non-null
+       -- Spruced up mycrypt_custom.h to trap more errors and also help prevent LTMSSE from being defined
+          on non-i386 platforms by accident.
+       -- Added RSA/ECC/DH speed tests to x86_prof and cleaned it up to build with zero warnings
+       -- Changed Fortuna to count only entropy [not the 2 byte header] added to pool[0] into the 
+          reseed mechanism.  
+       -- Added "export_size" member to prng_descriptor tables so you can know in advance the size of 
+          the exported state for any given PRNG.  
+       -- Ported over patch on LTM 0.30 [not ready to release LTM 0.31] that fixes bug in mp_mul()/mp_div()
+          that used to result in negative zeroes when you multiplied zero by a negative integer.  
+          (patch due to "Wolfgang Ehrhardt" <Wolfgang.Ehrhardt@munich.netsurf.de>)
+       -- Fixed rsa_*decrypt_key() and rsa_*verify_hash() to default to invalid "stat" or "res".  This way
+          if any of the higher level functions fail [before you get to the padding] the result will be in
+          a known state].  Applied to both v2 and v1.5 padding helpers.
+       -- Added MACs to x86_prof
+       -- Fixed up "warnings" in x86_prof and tv_gen
+       -- Added a "profiled" target back [for GCC 3.4 and ICC v8].  Doesn't seem to help but might be worth
+          tinkering with.
+       -- Beefed up load/store test in demos/test
+
+       ++ New note, in order to use the optimized LOAD/STORE macros your platform
+          must support unaligned 32/64 bit load/stores.  The x86s support this
+          but some [ARM for instance] do not.  If your platform cannot perform
+          unaligned operations you must use the endian neutral code which is safe for 
+          any sort of platform.
+
+July 23rd, 2004
+v0.97b -- Added PKCS #1 v1.5 RSA encrypt/sign helpers (like rsa_sign_hash, etc...)
+       -- Added missing prng check to rsa_decrypt_key() [not critical as I don't use 
+          descriptors directly in that function]
+       -- Merged in LTM-SSE, define LTMSSE before you build and you will get SSE2 optimized math ;-)
+          (roughly 3x faster on a P4 Northwood).  By default it will compile as ISO C portable
+          code (when LTMSSE is undefined).
+       -- Fixed bug in ltc_tommath.h where I had the kara/toom cutoffs not marked as ``extern''
+          Thanks to "Stefan Arentz" <stefan at organicnetwork.net>
+       -- Steven Dake <scd@broked.org> and Richard Amacker <ramacker@yahoo.com> submitted patches to 
+          fix pkcs_5_2().  It now matches the output of another crypto library.  Whoops... hehehe
+       -- Updated PRNG api.  Added Fortuna PRNG to the list of supported PRNGs
+       -- Fixed up the descriptor tables since globals are automatically zero'ed on startup.
+       -- Changed RC4 to store it's output.  If you want to encrypt with RC4
+          you'll have to do the XOR yourself.
+       -- Fixed buffer overflows/overruns in the HMAC code.  
+
+       ++ API change for the PRNGs there now is a done() function per PRNG.  You
+          should call it when you are done with a prng state.  So far it's
+          not absolutely required (won't cause problems) but is a good idea to
+          start.  
+
+
+June 23rd, 2004
+v0.97a ++ Fixed several potentially crippling bugs... [read on]
+       -- Fixed bug in OAEP decoder that would incorrectly report 
+          buffer overflows. [Zhi Chen]
+       -- Fixed headers which had various C++ missing [extern "C"]'s
+       -- Added "extern" to sha384_desc descriptor which I removed by mistake
+       -- Fixed bugs in ENDIAN_BIG macros using the wrong byte order [Matt Johnston]
+       -- Updated tiger.c and des.c to not shadow "round" which is intrinsic on
+          some C compilers.
+       -- Updated demos/test/rsa_test.c to test the RSA functionality better
+       ++ This update has been tested with GCC [v3.3.3], ICC [v8] and MSVC [v6+SP6] 
+          all on a x86 P4  [GCC/ICC tested in Gentoo Linux, MSVC in WinXP]
+       ++ Outcome: The bug Zhi Chen pointed out has been fixed.  So have the bugs
+          that Matt Johnston found.  
+
+June 19th, 2004
+v0.97  -- Removed spurious unused files [arrg!]
+       -- Patched buffer overflow in tim_exptmod()
+       -- Fixed buffer overrun bug in pkcs_1_v15_es_decode()
+       -- Reduced stack usage in PKCS #1 v2.0 padding functions (by several KBs)
+       -- Removed useless extern's that were an artifact from the project start... ;-)
+       -- Replaced memcpy/memset with XMEMCPY and XMEMSET for greater flexibility
+       -- fixed bugs in hmac_done()/hmac_init()/[various others()] where I didn't trap errors 
+       -- Reduced stack usage in OMAC/PMAC/HMAC/EAX/OCB/PKCS#5 by mallocing any significant sized
+          arrays (e.g. > 100 bytes or so).  Only in non-critical functions (e.g. eax_init())
+       -- "Zhi Chen" <zhi@massiveincorporated.com> pointed out that rsa_decrypt_key() requires
+          an incorrect output size (too large).  Fixed.
+       -- Added a "pretty" target to the GCC makefile.  Requires PERL.  It is NEAT!
+       -- Minor updates to ch1 of the manual.
+       -- Cleaned up the indentation and added comments to rsa_make_key(), rsa_exptmod() and 
+          rsa_verify_hash()
+       -- Updated makefile.icc so the "install" target would work ;-)
+       -- Removed demos/test.c [deprecated from demos/test/test.c]
+       -- Changed MAXBLOCKSIZE from 128 to 64 to reflect the true size...
+
+May 30th, 2004
+v0.96  -- Removed GF and Keyring code
+       -- Extended OAEP decoder to distinguish better [and use a more uniform API]
+       -- Changed PSS/OAEP API slightly to be more consistent with other PK functions (order of arguments)
+       -- rsa_exptmod() now pads with leading zeroes as per I2OSP.
+       -- added error checking to yarrow code
+       --  pointed out that tommath.h from this distro will overwrite tommath.h
+          from libtommath.  I changed this to ltc_tommath.h to avoid any such problems.
+       -- Fixed bug in PSS encoder/decoder that didn't handle the MSB properly
+       -- refactored AES, now sports an "encrypt only" descriptor which uses half as much code space.
+       -- modded Yarrow to try and use refactored AES code and added WHIRLPOOL support (d'oh) ;-)
+       -- updated ECB, OCB and CBC decrypt functions to detect when "encrypt only" descriptor is used.
+       -- replaced old RSA code with new code that uses PKCS #1 v2.0 padding
+       -- replaced old test harness with new over-engineer'ed one in /demos/test/
+       -- updated cbc/cfb/ofb/ctr code with setiv/getiv functions to change/read the IV without re-keying.
+       -- Added PKCS #1 v1.5 RSA encryption and signature padding routines
+       -- Added DER OID's to most hash descriptors (as many as I could find) 
+       -- modded rsa_exptmod() to use timing-resilient tim_exptmod() when doing private key operations 
+          added #define RSA_TIMING which can turn on/off this feature.
+       -- No more config.pl so please just read mycrypt_custom.h for build-time tweaks
+       -- Small update to rand_prime()
+       -- Updated sha1, md5 and sha256 so they are smaller when SMALL_CODE is defined.  If you want speed though,
+          you're going to have to undefine SMALL_CODE ;-)
+       -- Worked over AES so that it's even smaller now [in both modes].
+       
+May 12th, 2004
+v0.95  -- Optimized AES and WHIRLPOOL for SMALL_CODE by taking advantage of the fact
+          the transforms are circulant.  AES dropped 5KB and WHIRLPOOL dropped 13KB
+          using the default build options on the x86.
+       -- Updated eax so the eax_done() would clear the state [like hmac,pmac,ocb] when
+          CLEAN_STACK has been defined.
+       -- added LTC_TEST support to rmd160
+       -- updates to mycrypt_pk.h
+       -- updated rand_prime() to faciliate making RSA composites 
+       -- DSA/RSA now makes composites of the exact size desired.
+       -- Refactored quite a bit of the code, fewer functions per C file
+       -- cleaned up the makefiles to organize the objects logically
+       -- added ICC makefile along with "profiled" targets for both GNU and ICC compilers
+       -- Marked functions for removal before v1.00 see PLAN for more information
+       -- GCC 3.4.0 tested and seems to work
+       -- Added PKCS #5 support
+       -- Fixed typo in comment header of .C files  ;-)
+       -- Added PKCS #1 OAEP and PSS support.  
+       
+Feb 20th, 2004
+v0.94  -- removed unused variables from ocb.c and fixed it to match known test vectors.
+       -- Added PMAC support, minor changes to OMAC/EAX code [I think....]
+       -- Teamed up with Brian Gladman.  His code verifies against my vectors and my code
+          verifies against his test vectors.  Hazaa for co-operation!
+       -- Various small changes (added missing ARGCHKs and cleaned up indentation)
+       -- Optimization to base64, removed unused variable "c"
+       -- Added base64 gen to demos/tv_gen.c
+       -- Fix to demos/x86_prof.c to correctly identify the i386 architecture... weird...
+       -- Fixed up all of the PK code by adding missing error checking, removed "res" variables,
+          shrunk some stack variables, removed non-required stack variables and added proper
+          error conversion from MPI to LTC codes.  I also spotted a few "off by one" error
+          checking which could have been used to force the code to read past the end of
+          the buffer (in theory, haven't checked if it would work) by a few bytes.
+       -- Added checks to OUTPUT_BIGNUM so the *_export() functions cannot overflow the output and I 
+          also modded it so it stores in the output provided to the function (that is not on
+          the local stack) which saves memory and time.
+       -- Made SAFER default to disabled for now (plans are to cleanhouse write an implementation later)
+       -- Added the 512-bit one-way hash WHIRLPOOL which clocks in at 138 cycles per byte on my
+          Athlon XP [for comparison, SHA-512 clocks in at 77 cycles per byte].  This code uses the 
+          teams new sbox design (not the original NESSIE one).

+Jan 25th, 2004
+v0.93  -- [note: deleted v0.93 changes by accident... recreating from memory...]
+       -- Fix to RC2 to not deference pointer before ARGCHK
+       -- Fix to NOEKEON to match published test vectors as well as cleaned up the code a bit
+       -- Optimized Twofish [down to 28 cycles/byte on my box] and Blowfish
+       -- Fix to OMAC to test cipher block size first [prevents wasting any time]
+       -- Added more OMAC test vectors
+       -- Added EAX Encrypt+Authenticate support
+       -- Fix to DSA to check return of a few LTM functions I forgot [mp_to_unsigned_bin]
+       -- Added common headers to all C files
+       -- CTR mode supports big and little [default] endian counters now.  
+       -- fix to find_cipher_any() so that it can handle a fragmented cipher_descriptor table.
+       -- added find_hash_any() akin to find_cipher_any().
+       -- Added EAX code to demos/tv_gen.c  Hazaa! 
+       -- Removed SONY defines and files from codebase.
+       -- Added OCB support [patents be damned] and to demos/tv_gen.c
+       -- Merge all of the INPUT/OUTPUT BIGNUM macros (less toc) into mycrypt_pk.h
+       -- Made appropriate changes to the debug string in crypt.c
+
+Dec 24th, 2003
+v0.92  -- Updated the config.pl script so the options have more details.
+       -- Updated demos/tv_gen to include RIPEMD hashes
+       -- Updated Twofish so when TWOFISH_ALL_TABLES is defined a pre-computed RS table
+          is included [speedup: slight, about 4k cycles on my Athlon].
+       -- Re-wrote the twofish large key generation [the four 8x32 key dependent tables].  Now about twice as fast.
+          With both optimizations [e.g. TWOFISH_ALL_TABLES defined] a 128-bit Twofish key can now be scheduled
+          in 26,000 cycles on my Athlon XP [as opposed to 49,000 before] when optimized for size.
+       -- config.pl has been updated so rmd128.o and rmd160.o are objects included in the build [oops]
+       -- Andrew Mann found a bug in rsa_exptmod() which wouldn't indicate if the wrong type of key was specified
+          (e.g. not PK_PRIVATE or PK_PUBLIC)
+       -- Fixed up demos/x86_prof so it sorts the output now :-)  
+       -- The project is now powered by radioactive rubber pants.
+       -- Fixed dh_encrypt_key() so if you pass it a hash with a smaller output than the input key it 
+          will return CRYPT_INVALID_HASH [to match what ecc_encrypt_key() will do]
+       -- Merge the store/encrypt key part of ecc_encrypt_key() as per dh_encrypt_key() [can you guess what I'm upto?]
+       -- Massive updates to the prime generation code.  I use the LTM random prime functions [and provide a nice 
+          interface between the LTC PRNG's and the LTM generic prng prototype].  I also use a variable number of tests
+          depending on the input size.  This nicely speeds up most prime generation/testing within the library.
+       -- Added SHA-224 to the list of hashes.
+       -- Made HMAC test vectors constant and static [takes ROM space instead of RAM]
+       -- This release was brought to you by the letter P which stands for Patent Infringement.
+       -- Added generic HASH_PROCESS macro to mycrypt_hash.h which simplifies the hash "process" functions
+          I also optimized the compression functions of all but MD2 to not perform input copies when avoidable.
+       -- Removed the division from the Blowfish setup function [dropped 3k cycles on my Athlon]
+       -- Added stack cleaning to rijndael, cast5 so now all ciphers have CLEAN_STACK code.  
+       -- Added Skipjack to the list of ciphers [made appropriate changes to demos/test.c, demos/tv_gen.c and 
+          demos/x86_prof.c]
+       -- Added mechanical testing to cipher test vector routines.  Now it encrypts 1000 times, then decrypts and
+          compares.  Any fault (e.g. bug in code, compiler) in the routines is likely to show through.  Doesn't
+          stress test the key gen though...
+       -- Matt Johnson found a bug in the blowfish.c  apparently I was out of my mind and put twofish defines in there 
+          The code now builds with any config.  Thanks.
+       -- Added OMAC1 Message Authentication Code support to the library.
+       -- Re-prototyped the hash "process" and "done" to prevent buffer overflows [which don't seem easy to exploit].  
+          Updated HMAC code to use them too.  Hazaa!
+       -- Fixed bug in ECC code which wouldn't do an _ARGCHK on stat in ecc_verify_hash().
+       -- Fixed [temp fix] bug in all PK where the OUTPUT_BIGNUM macros would not trap errors on the to_unsigned_bin 
+          conversion [now returns CRYPT_MEM, will fix it up better later]
+       -- Added DSA to the list of supported PK algorithms.  
+       -- Fixed up various ciphers to &255 the input key bytes where required [e.g. where used to index a table] to prevent
+          problems on platforms where CHAR_BIT != 8 
+       -- Merged in LibTomMath v0.28
+       -- Updated demos/x86_prof.c to use Yarrow during the key sched testing [was horribly slow on platforms with blockable
+          /dev/random]. 
+       -- Added OMAC/HMAC tests to demos/tv_gen and I now store the output of this in notes/ 
+       -- Fixed a bug in config.pl that wouldn't have TWOFISH_TABLES defined by default (too many commas on the line)
+       -- Fixed bug in hmac_done().  Apparently FIPS-198 [HMAC] specifies that the output can be truncated.  My code
+          would not support that (does now just like the new OMAC code).
+       -- Removed "hashsize" from hmac_state as it wasn't being used.
+       -- Made demos/test.c stop if OMAC or HMAC tests fail (instead of just printing a failed message and keep going).
+       -- Updated notes/tech0003.txt to take into account the existence of Skipjack [also I fixed a few typos].
+       -- Slight changes to Noekeon, with SMALL_CODE undefined it uses a fully unrolled version.  Dropped +10 cycles/byte
+          on my Athlon (35 cycles per byte or 410.4Mbit/sec at 1795Mhz)
+       -- Added _ARGCHK() calls to is_prime() for the two input pointers.
+
+Sept 25th, 2003
+v0.91  -- HMAC fix of 0.90 was incorrect for keys larger than the block size of the hash.
+       -- Added error CRYPT_FILE_NOTFOUND for the file [hmac/hash] routines.
+       -- Added RIPEMD hashes to the hashsum demo.
+       -- Added hashsum demo to MSVC makefile.
+       -- Added RMD160 to the x86_prof demo [oops]
+       -- Merged in LibTomMath-0.27 with a patch to mp_shrink() that will be in LibTomMath-0.28
+          Fixes another potential memory leak.
+
+Sept 7th, 2003
+v0.90  -- new ROL/ROR for x86 GCC
+       -- Jochen Katz submitted a patch to the makefile to prevent "make" from making the .a library
+          when not required.
+       == By default the KR code is not enabled [it's only a demo anyways!]
+       -- changed the "buf" in ecc_make_key from 4KB to 128 bytes [since the largest key is 65 bytes]
+       -- hmac_done() now requires you pass it the size of the destination buffer to prevent
+          buffer overflows.  (API CHANGE)
+       -- hmac/hash filebased routines now return CRYPT_NOP if NO_FILE is defined.
+       -- I've removed the primes from dh.c and replaced them with DR safe primes suitable for the default
+          configuration of LibTomMath.  Check out these comparisons on a 1.3Ghz Athlon XP, optimized for size,
+
+768-bit,     4 vs.  10
+1024-bit,    8 vs.  18
+1280-bit,   12 vs.  34
+1536-bit,   20 vs.  56
+1792-bit    28 vs.  88
+2048-bit,   40 vs. 124
+2560-bit,   71 vs. 234
+3072-bit,  113 vs. 386
+4096-bit,  283 vs. 916
+
+          Times are all in milliseconds for key generation.  New primes times on the left.  This makes the code binary
+          incompatible with previous releases.  However, this addition is long overdue as LibTomMath has supported DR
+          reductions for quite some time.
+       -- Added RIPE-MD 128 and 160 to the list of supported hashes [10 in total].
+       -- The project has been released as public domain.  TDCAL no longer applies.
+
+July 15th, 2003
+v0.89  -- Fix a bug in bits.c which would prevent it from building with msvc
+       -- Merged in LibTomMath v0.24 [and I used the alloc/free macros this time!]
+       -- Removed the LTC version of next_prime() and replaced it with a call to the
+          mp_prime_next_prime() from LibTomMath
+       -- reverted bits.c to the 0.86 copy since the new one doesn't build in MSVC
+          or cygwin.
+
+Jul 10th, 2003
+v0.88  -- Sped up CAST5 key schedule for MSVC
+       -- added "ulong32" which allows people on 64-bit platforms to force the 32-bit tables in
+          ciphers like blowfish and AES to be 32-bits.  E.g. when unsigned long is 64-bits.
+       -- Optimized the SAFER-SK64, SAFER-SK128, SAFER+, RC5 and RC6 key schedule [big time!]
+       -- Optimized SHA-1 and SHA-256 quite a bit too.
+       -- Fixed up the makefile to use -fomit-frame-pointer more liberally
+       -- Added tv_gen program which makes test vectors for ciphers/hashes
+       -- Merged in LibTomMath v0.22
+       
+Jun 19th, 2003
+v0.87  -- Many MSVC optimizations to the code base
+       -- Improved the AES and Twofish key schedule [faster, more constant time]
+       -- Tons of optimizations here and there.  
+       
+Jun 15th, 2003
+v0.86  -- Fixed up AES to workaround MSVC optimizer bug
+       -- Merged in fresh LTM base [based on v0.20] so there are no warnings with MSVC
+       -- Wrote x86_prof which will time the hashes and ciphers downto cycles per byte.
+       -- Fixed up demos/encrypt to remove serpent_desc from the list
+       -- Re-enabled MSVC optimizations w00t w00t
+       -- Replaced "errno" with "err" in all functions that had it so it wouldn't clash
+          with the global "errno"
+       -- Removed a set of unused variables from certain functions
+       -- Removed {#line 0 "..."} stuff from mpi.c to comply with ISO C  :-)
+       
+Jun 11th, 2003
+v0.85  -- Swapped in a new AES routine
+       -- Removed Serpent
+       -- Added TDCAL policy document
+       
+Jun 1st, 2003
+v0.84  -- Removed a 4KB buffer from rsa_decrypt_key that wasn't being used no more
+       -- Fixed another potential buffer problem.  Not an overflow but could cause the 
+          PK import routines to read past the end of the buffer.
+       -- Optimized the ECC mulmod more by removing a if condition that will always be false
+       -- Optimized prime.c to not include a 2nd prime table, removed code from is_prime calls prime
+          test from LibTomMath now
+       -- Added LTC_TEST define which when defined will enable the test vector routines [see mycrypt_custom.h]
+       -- Removed ampi.o from the depends cuz it ain't no not working in *nix with it [routines are in mpi.c now].
+        
+
+Mar 29th, 2003
+v0.83  -- Optimized the ecc_mulmod, it's faster and takes less heap/stack space
+       -- Fixed a free memory error in ecc_mulmod and del_point which would try to free NULL
+       -- Fixed two serious bugs in rsa_decrypt_key and rsa_verify_hash that would allow a trivialy
+          buffer overflow.
+       -- Fixed a bug in the hmac testing code if you don't register all the hashes it won't return
+          errors now.
+       
+Mar 15th, 2003
+v0.82  -- Manual updated
+       -- Added MSVC makefile [back, actually its written from scratch to work with NMAKE]
+       -- Change to HMAC helper functions API to avoid buffer overflow [source changes]
+       -- the rsa_encrypt_key was supposed to reject key sizes out of bounds ... 
+          same fix to the rsa_sign_hash 
+       -- Added code to ensure that that chaining mode code (cfb/ofb/ctr/cbc) have valid
+          structures when being called.  E.g. the indexes to the pad/ivs are not out of bounds
+       -- Cleaned up the DES code and simplified the core desfunc routine.
+       -- Simplified one of the boolean functions in MD4
+       
+Jan 16th, 2003
+v0.81  -- Merged in new makefile from Clay Culver and Mike Frysinger
+       -- Sped up the ECC mulmod() routine by making the word size adapt to the input.  Saves a whopping 9 point
+          operations on 521-bit keys now (translates to about 8ms on my Athlon XP).  I also now use barrett reduction
+          as much as possible.  This sped the routine up quite a bit.
+       -- Fixed a huge flaw in ecc_verify_hash() where it would return CRYPT_OK on error... Now fixed.
+       -- Fixed up config.pl by fixing an invalid query and the file is saved in non-windows [e.g. not CR/LF] format
+          (fix due to Mika Bostr?m)
+       -- Merged in LibTomMath for kicks
+       -- Changed the build process so that by default "mycrypt_custom.h" is included and provided
+          The makefile doesn't include any build options anymore
+       -- Removed the PS2 and VC makefiles.
+       
+Dec 16th, 2002
+v0.80  -- Found a change I made to the MPI that is questionable.  Not quite a bug but definately not desired.  Had todo
+          with the digit shifting.  In v0.79 I simply truncated without zeroing.  It didn't cause problems during my
+          testing but I fixed it up none the less.
+       -- Optimized s_mp_mul_dig() from MPI to do a minimal number of passes.
+       -- Fixed in rsa_exptmod() where I was getting the size of the result.  Basically it accomplishes the same thing
+          but the fixed code is more readable.
+       -- Fixed slight bug in dh_sign_hash() where the random "k" value was 1 byte shorter than it should have been.  I've
+          also made the #define FAST_PK speed up signatures as well.  Essentially FAST_PK tells the DH sub-system to 
+          limit any private exponent to 256-bits.   Note that when FAST_PK is defined does not make the library
+          binary or source incompatible with a copy of the library with it undefined.
+       -- Removed the DSA code.  If you want fast diffie-hellman just define FAST_PK :-)
+       -- Updated dh_sign_hash()/dh_verify_hash() to export "unsigned" bignums.  Saves two bytes but is not binary
+          compatible with the previous release... sorry!  I've performed the same fix to the ecc code as well.
+       -- Fixed up the PK code to remove all use of mp_toraw() and mp_read_raw() [get all the changes out of the way now]
+       -- Fixed a bug in the DH code where it missed trapping a few errors if they occurred.
+       -- Fixed a slight "its-not-a-bug-but-could-be-done-better" bug in the next_prime() function.  Essentially it was
+          testing to ensure that in the loop that searches for the next candidate that the step never grows beyond
+          65000.  Should have been testing for MP_DIGIT_MAX
+       -- Spruced up the config.pl script.  It now makes a header file "mycrypt_custom.h" which can be included *before*
+          you include mycrypt.h.  This allows you to add libtomcrypt to a project without completely changing your make
+          system around.  Note that you should use the makefile it writes to at least build the library initially.
+       -- Used splint to check alot of the code out.  Tons of minor fixes and explicit casts added.
+       -- Also made all the internal functions of MPI are now static to avoid poluting the namespace
+       -- **Notice**:  There are no planned future releases for at least a month from the this release date.
+       
+Dec 14th, 2002
+v0.79  -- Change to PK code [binary and source].  I made it so you have to pass the buffer size to the *_decrypt_key and
+          *_verify_hash functions.  This prevents malformed packets from performing buffer overflows.  I've also trimmed
+          the packet header size [by 4 bytes].
+       -- Made the test program halt on the first error it occurs.  Also made it trap more errors than before.
+       -- Wrote the first chapter of my new book [DRAFT!], not in this package but check my website!
+       -- Included a perl script "config.pl" that will make "makefile.out" according to the users needs.  
+       -- Added shell script to look for latest release
+       -- Merge DH and ECC key defines from mycrypt_cfg.h into the makefiles
+       -- updated the makefile to use BSD friendly archiving invokations
+       -- Changed the DH and ECC code to use base64 static key settings [e.g. the primes].  Dropped the code size by 3KB
+          and is ever-so-slightly faster than before.
+       -- added "mp_shrink" function to shrink the size of bignums.  Specially useful for PK code :-)
+       -- Added new exptmod function that calculates a^b mod c with fewer multiplies then before [~20% for crypto
+          sized numbers].  Also added a "low mem" variant that doesn't use more than 20KB [upto 4096 bit nums] of
+          heap todo the calculation.  Both are #define'able controlled
+       -- Added XREALLOC macro to provide realloc() functionality.
+       -- Added fix where in rsa_import() if you imported a public key or a non-optimized key it would free the mp_int's
+          not being used.
+       -- Fixed potential bug in the ECC code.  Only would occur on platforms where char is not eight bits [which isn't
+          often!]
+       -- Fixed up the ECC point multiplication, its about 15% faster now
+       -- While I was at it [since the lib isn't binary backwards compatible anyways] I've fixed the PK export routines
+          so they export as "unsigned" types saving 1 byte per bignum outputted.  Not a lot but heck why not.
+          
+Nov 28th, 2002
+v0.78  -- Made the default ARGCHK macro a function call instead which reduced the code size from 264KB to 239KB.
+       -- Fixed a bug in the XTEA keysize function which called ARGCHK incorrectly.
+       -- Added Noekeon block cipher at 2,800 bytes of object code and 345Mbit/sec it is a welcome addition.
+       -- Made the KR code check if the other PK systems are included [provides error when building otherwise].
+       -- Made "aes" an alias for Rijndael via a pre-processor macro.  Now you can use "aes_ecb_encrypt", etc... :-)
+          Thanks to Jean-Luc Cooke for the "buzzword conformance" suggestion.
+       -- Removed the old PK code entirely (e.g. rsa_sign, dh_encrypt).  The *_sign_hash and *_encrypt_key functions
+          are all that is to remain.
+       -- **NOTE** Changed the PK *_import (including the keyring) routine to accept a "inlen" parameter.  This fixes a
+          bug where improperly made key packets could result in reading passed the end of the buffer.  This means
+          the code is no longer source compatible but still binary compatible.
+       -- Fixed a few other minor bugs in the PK import code while I was at it.
+       
+Nov 26th, 2002
+v0.77  -- Updated the XTEA code to use pre-computed keys.  With optimizations for speed it achieves 222Mbit/sec
+          compared to the 121Mbit/sec before.  It is 288 bytes bigger than before.
+       -- Cleaned up some of the ciphers and hashes (coding style, cosmetic changes)
+       -- Optimized AES slightly for 256-bit keys [only one if statement now, still two for 192-bit keys]
+       -- Removed most test cases from Blowfish, left three of them there.  Makes it smaller and faster to test.
+       -- Changed the primality routines around.  I now use 8 rounds of Rabin-Miller, I use 256 primes in the sieve
+          step and the "rand_prime" function uses a modified sieve that avoids alot of un-needed bignum work.
+       -- Fixed a bug in the ECC/DH signatures where the keys "setting" value was not checked for validity.  This means
+          that a invalid value could have caused segfaults, etc...
+       -- **NOTE** Changed the way the ECC/DH export/import functions work.  They are source but not binary compatible
+          with v0.76.  Essentially insteading of exporting the setting index like before I export the key size.  Now
+          if you ever re-configure which key settings are supported the lib will still be able to make use of your 
+          keys.
+       -- Optimized Blowfish by inlining the round function, unrolling it for four rounds then using a for loop for the 
+          rest.  It achieves a rate of 425Mbit/sec with the new code compared to 314Mbit/sec before.  The new blowfish 
+          object file is 7,813 bytes compared to 8,663 before and is 850 bytes smaller.  So the code is both smaller and 
+          faster!
+       -- Optimized Twofish as well by inlining the round function.  Gets ~400Mbit/sec compared to 280Mbit/sec before
+          and the code is only 78 bytes larger than the previous copy.
+       -- Removed SMALL_PRIME_TAB build option.  I use the smaller table always.
+       -- Fixed some mistakes concerning prime generation in the manual.
+       -- [Note: sizes/speeds are for GCC 3.2 on an x86 Athlon XP @ 1.53Ghz]
+
+Nov 25th, 2002
+v0.76  -- Updated makefiles a bit more, use "-Os" instead of "-O2" to optimize for size.  Got the lib
+          downto 265KB using GCC 3.2 on my x86 box.
+       -- Updated the SAFER+, Twofish and Rijndael test vector routine to use the table driven design.
+       -- Updated all other test vector routines to return as soon as an error is found
+       -- fixed a bug in the test program where errors in the hash test routines would not be reported
+          correctly.  I found this by temporarily changing one of the bytes of the test vectors.  All the
+          hashes check out [the demos/test.c would still have reported an error, just the wrong one].

+Nov 24th, 2002
+v0.75  -- Fixed a flaw in hash_filehandle, it should ARGCHK that the filehandle is not NULL
+       -- Fixed a bug where in hash_file if the call to hash_filehandle failed the open file would 
+          not be closed.
+       -- Added more strict rules to build process, starting to weed out "oh this works in GCC" style code
+          In the next release "-Wconversion" will be enabled which will deal with all implicit casts.
+
+Nov 22nd, 2002 [later in the day]
+v0.74  -- Wrote a small variant of SAFER+ which shaved 50KB off the size of the library on x86 platforms
+       -- Wrote a build option to remove the PK packet functions [keeps the encrypt_key/sign_hash functions]
+       -- Wrote a small variant of Rijndael (trimmed 13KB)
+       -- Trimmed the TIGER/192 hash function a bit
+       -- Overall the entire lib compiled is 295KB [down from 400KB before]
+       -- Fixed a few minor oversights in the MSVC makefile
+
+Nov 22nd, 2002
+v0.73  -- Fixed bug in RC4 code where it could only use 255 byte keys.
+       -- Fixed bug in yarrow code where it would allow cast5 or md2 to be used with it...
+       -- Removed the ecc compress/expand points from the global scope.  Reduces namespace polution
+       -- Fixed bug where if you used the SPRNG you couldn't pass NULL as your prng_state which you should be
+          able todo since the SPRNG has no state...
+       -- Corrected some oversights in the manual and the examples...
+       -- By default the GF(2^W) math library is excluded from the build.  The source is maintained because I wrote it
+          and like it :-).  This way the built library is a tad smaller
+       -- the MSVC makefile will now build for a SPACE optimized library rather than TIME optimized.
+
+Nov 21th, 2002
+v0.72  -- Fixed bug in the prime testing.  In the Miller-Rabin test I was raising the base to "N-1" not "r".
+          The math still worked out fine because in effect it was performing a Fermat test.  Tested the new code and it 
+          works properly
+       -- Fixed some of the code where it was still using the old error syntax
+       -- Sped up the RSA decrypt/sign routines
+       -- Optimized the ecc_shared_secret routine to not use so much stack
+       -- Fixed up the makefile to make releases where the version # is in the file name and directory it will unzip
+          to
+
+Nov 19th, 2002
+v0.71  -- HELP TOM.  I need tuition for the January semester.  Now I don't want to force donations [nor will I ever]
+          but I really need the help!  See my website http://tom.iahu.ca/help_tom.html for more details.  Please help
+          if you can! 
+       --------------------------------------------------------------------------------------------------------------
+       -- Officially the library is no longer supported in GCC 3.2 in windows [cygwin].
+          In windows you can either use GCC 2.95.3 or try your luck with 3.2  It seems that
+          "-fomit-frame-pointer" is broken in the windows build [but not the linux x86 build???]
+          If you simply must use 3.2 then I suggest you limit the optimizations to simply "-O2"
+       -- Started new error handling API.  Similar to the previous except there are more error codes than just
+          CRYPT_ERROR
+       -- Added my implementation of the MD2 hash function [despite the errors in the RFC I managed to get it right!]
+       -- Merged in more changes from Sky Schulz.  I have to make mention here that he has been a tremendous help in 
+          getting me motivated to make some much needed updates to the library!
+       -- Fixed one of the many mistakes in the manual as pointed out by Daniel Richards
+       -- Fixed a bug in the RC4 code [wasn't setting up the key correctly]
+       -- Added my implementation of the CAST5 [aka CAST-128] block cipher (conforms...)
+       -- Fixed numerous bugs in the PK code.  Essentially I was "freeing" keys when the import failed.  This is neither
+          required nor a good a idea [double free].  
+       -- Tom needs a job.
+       -- Fixed up the test harness as requested by Sky Schulz.  Also modifed the timing routines to run for X seconds
+          and count # of ops performed.  This is more suitable than say encrypting 10 million blocks on a slow processor
+          where it could take minutes!
+       -- Modified test programs hashsum/encrypt to use the new algorithms and error handling syntax
+       -- Removed the PKCS code since it was incomplete.  In the future I plan on writing a "add-on" library that
+          provides PKCS support... 
+       -- updated the config system so the #defines are in the makefiles instead of mycrypt_cfg.h  
+       -- Willing to work on an hourly basis for 15$ CDN per hour.
+       -- updated the test program to not test ciphers not included
+       -- updated the makefile to make "rsa_sys.c" a dependency of rsa.o [helps develop the code...]
+       -- fixed numerous failures to detect buffer overflows [minor] in the PK code.
+       -- fixed the safer [64-bit block version] test routines which didn't check the returns of the setup
+          function
+       -- check out my CV at http://tom.iahu.ca/cv.html
+       -- removed the GBA makefile and code from demos/test.c [not a particularly useful demo...]
+       -- merged in rudimentary [for testing] PS2 RNG from Sky Schulz
+       -- merged in PS2 timer code [only shell included due to NDA reasons...]
+       -- updated HMAC code to return errors where possible
+       -- Thanks go to Sky Schulz who bought me a RegCode for TextPad [the official editor of libtomcrypt]
+
+Nov 12th, 2002
+v0.70  -- Updated so you can swap out the default malloc/calloc/free routines at build time with others. (Sky Schulz)
+       -- Sky Schulz contributed some code towards autodetecting the PS2 in mycrypt_cfg.h
+       -- Added PS2 makefile contributed by Sky Schulz [see a pattern forming?]
+       -- Added ability to have no FILE I/O functions at all (see makefile), Sky Schulz....
+       -- Added support for substituting out the clock() function (Sky Schulz)
+       -- Fixed up makefile to include new headers in the HEADERS variable
+       -- Removed "coin.c" as its not really useful anyways
+       -- Removed many "debug" printfs that would show up on failures.  Basically I wanted to ensure the only output
+          would be from the developer themselves.
+       -- Added "rc4.c" a RC4 implementation with a PRNG interface.  Since RC4 isn't a block cipher it wouldn't work
+          too well as a block cipher.
+       -- Fixed ARGCHK macro usage when ARGTYPE=1 throughout the code
+       -- updated makefile to make subdirectory properly (Sku Schulz)
+       -- Started towards new API setup.  Instead of checking for "== CRYPT_ERROR" you should check "!= CRYPT_OK"
+          In future releases functions will return things other than CRYPT_ERROR on error to give more useful
+          thread safe error reporting.  The manual will be updated to reflect this.  For this release all
+          errors are returned as CRYPT_ERROR (except as noted) but in future releases this will change.         
+       -- Removed the zlib branch since its not really required anyways.  Makes the package smaller
+
+Nov 11th, 2002
+v0.69  -- Added ARGCHK (see mycrypt_argchk.h) "arguement checking" to all functions that accept pointers
+       -- Note I forgot to change the CRYPT version tag in v0.68... fixed now.
+
+Nov 8th, 2002
+v0.68  -- Fixed flaw in kr_import/kr_export that wasted 4 bytes.  Source but not binary compatible with v0.67
+       -- Fixed bug in kr_find_name that used memcmp to match strings.  Uses strncmp now.
+       -- kr_clear now sets the pointer to NULL to facilate debugging [e.g. using the keyring after clearing]
+       -- static functions in _write/_read in keyring.c now check the return of ctr_encrypt/ctr_decrypt.
+       -- Updated blowfish/rc2/rc5/rc6 keysize() function to not reject keys larger than the biggest key the
+          respective ciphers can use.  
+       -- Fixed a bug in hashsum demo that would report the hash for files that don't exist!
+
+Oct 16th, 2002
+v0.67  -- Moved the function prototypes into files mycrypt_*.h.  To "install" the lib just copy all the 
+          header files "*.h" from the base of this project into your global include path.
+       -- Made the OFB/CFB/CTR functions use "unsigned long" for the length instead of "int"
+       -- Added keyring support for the PK functions
+       -- ***API CHANGE*** changed the ecc_make_key and dh_make_key to act more like rsa_make_key.  Basically
+          move the first argument to the next to last.
+       -- Fixed bug in dh_test() that wouldn't test the primality of the order of the sub-group
+       -- replaced the primes in the DH code with new ones that are larger than the size they are 
+          associated with.  That is a 1024-bit DH key will have a 1025-bit prime as the modulus
+       -- cleaned up all the PK code, changed a bit of the API around [not source compatible with v0.66]
+       -- major editing of the manual, started Docer program
+       -- added 160 and 224 bit key settings for ECC.  This makes the DH and ECC binary wise incompatible with v0.66
+       -- Added an additional check for memory errors in is_prime() and cleaned up prime.c a bit
+       -- Removed ID_TAG from all files [meh, not a big fan...]
+       -- Removed unused variable from yarrow state and made AES/SHA256 the default cipher/hash combo
+       -- Fixed a bug in the Yarrow code that called prng_is_valid instead of cipher_is_valid from yarrow_start()
+       -- The ECB/CBC/OFB/CFB/CTR wrappers now check that the cipher is valid in the encrypt/decrypt calls
+          Returns int now instead of void.
+
+Sept 24th, 2002
+v0.66  -- Updated the /demos/test.c program to time the hashes correctly.  Also it uses the yarrow PRNG for all of the 
+          tests meaning its possible to run on RNG less platforms 
+       -- Updated the /demos/hashsum.c program to hash from the standard input
+       -- Updated the RSA code to make keys a bit quicker [update by Wayne Scott] by not making both primes at the same
+          time.
+       -- Dan Kaminsky suggested some cleanups for the code and the MPI config
+          Code ships in unix LF format by default now too... will still build in MSVC and all... but if you want
+          to read the stuff you'll have to convert it 
+       -- Changes to the manual to reflect new API [e.g. hash_memory/file have v0.65 prototypes]and some typos fixed
+
+Sept 20th, 2002
+v0.65  -- Wayne Scott (wscott@bitmover.com) made a few of suggestions to improve the library.  Most 
+          importantly he pointed out the math lib is not really required.  He's also tested the lib on 18 
+          different platforms.  According to him with only a few troubles [lack of /dev/random, etc] the 
+          library worked as it was supposed to.  You can find the list at 
+          http://www.bitkeeper.com/Products.BitKeeper.Platforms.html
+       -- Updated the hash_file and hash_memory functions to keep track of the size of the output
+       -- Wayne Scott updated the demos/test.c file to use the SPRNG less and Yarrow more
+       -- Modified the mycrypt_cfg.h to autodetect x86-32 machines
+
+Sept 19th, 2002
+v0.64  -- wrote makefile for the GBA device [and hacked the demos/test.c file to support it conditionally]
+       -- Fixed error in PK (e.g. ECC, RSA, DH) import functions where I was clobbering the packet error messages
+       -- fixed more typos in the manual
+       -- removed all unused variables from the core library (ignore the ID_TAG stuff)
+       -- added "const char *crypt_build_settings" string which is a build time constant that gives a listing
+          of all the build time options.  Useful for debugging since you can send that to me and I will know what 
+          exactly you had set for the mycrypt_cfg.h file.
+       -- Added control over endianess.  Out of the box it defaults to endianess neutral but you can trivially 
+          configure the library for your platform.  Using this I boosted RC5 from 660Mbit/sec to 785Mbit/sec on my 
+          Athlon box.  See "mycrypt_cfg.h" for more information.
+
+Sept 11th, 2002
+v0.63  -- Made hashsum demo output like the original md5sum program 
+       -- Made additions to the examples in the manual (fixed them up a bunch)
+       -- Merged in the base64 code from Wayne Scott (wscott@bitmover.com)
+
+Aug 29th, 2002
+v0.62  -- Added the CLEAN_STACK functionality to several of the hashes I forgot to update.
+
+Aug 9th, 2002
+v0.61  -- Fixed a bug in the DES code [oops I read something wrong].
+
+Aug 8th, 2002
+v0.60  -- Merged in DES code [and wrote 3DES-EDE code based on it] from Dobes V.
+
+Aug 7th, 2002
+v0.59  -- Fixed a "unsigned long long" bug that caused v0.58 not to build in MSVC.
+       -- Cleaned up a little in the makefile
+       -- added code that times the hash functions too in the test program
+
+Aug 3rd, 2002
+v0.58  -- Added more stack cleaning conditionals throughout the code.  
+       -- corrected some CLEAR_STACK conditionals... should have been CLEAN_STACK
+       -- Simplified the RSA, DH and ECC encrypt() routines where they use CTR to encode the message
+          now they only make one call to ctr_encrypt()/ctr_decrypt().
+
+Aug 2nd, 2002
+v0.57  -- Fixed a few errors messages in the SAFER code to actually report the correct cipher name.
+       -- rsa_encrypt() uses the "keysize()" method of the cipher being used to more accurately pick a
+          key size.  By default rsa_encrypt() will choose to use a 256-bit key but the cipher can turn that 
+          down if required.
+       -- The rsa_exptmod() function will now more reliably detect invalid inputs (e.g. greater than the modulus).
+       -- The padding method for RSA is more clearly documented.  Namely if you want to encrypt/sign something of length
+          N then your modulus must be of length 1+3N.  So to sign a message with say SHA-384 [48 bytes] you need a 
+          145 byte (1160 bits) modulus.  This is all in the manual now.
+       -- Added build option CLEAN_STACK which will allow you to choose whether you want to clean the stack or not after every
+          cipher/hash call
+       -- Sped up the hash "process()" functions by not copying one byte at a time.
+       ++ (added just after I uploaded...)
+          MD4 process() now handles input buffers > 64 bytes
+
+Aug 1st, 2002
+v0.56  -- Cleaned up the comments in the Blowfish code.
+       -- Oh yeah, in v0.55 I made all of the descriptor elements constant.  I just forgot to mention it.
+       -- fixed a couple of places where descriptor indexes were tested wrong.  Not a huge bug but now its harder
+          to mess up.
+       -- Added the SAFER [64-bit block] ciphers K64, SK64, K128 and SK128 to the library.
+       -- Added the RC2 block cipher to the library.
+       -- Changed the SAFER define for the SAFER+ cipher to SAFERP so that the new SAFER [64-bit] ciphers
+          can use them with less confusion.
+
+July 29th, 2002
+v0.55  -- My god stupid Blowfish has yet again been fixed.  I swear I hate that cipher.  Next bug in it and boom its out of the
+          library.  Use AES or something else cuz I really hate Blowfish at this stage....
+       -- Partial PKCS support [hint DONT USE IT YET CUZ ITS UNTESTED!]
+
+July 19th, 2002
+v0.54  -- Blowfish now conforms to known test vectors.  Silly bad coding tom!
+       -- RC5/RC6/Serpent all have more test vectors now [and they seemed to have been working before]
+
+July 18th, 2002
+v0.53  -- Added more test vectors to the blowfish code just for kicks [and they are const now too :-)]
+       -- added prng/hash/cipher is_valid functions and used them in all of the PK code so you can't enter the code
+          with an invalid index ever now.
+       -- Simplified the Yarrow code once again :-)
+
+July 12th, 2002
+v0.52  -- Fixed a bug in MD4 where the hash descriptor ID was the same as SHA-512.  Now MD4 will work with
+          all the routines...
+       -- Fixed the comments in SHA-512 to be a bit more meaningful
+       -- In md4 I made the PADDING array const [again to store it in ROM]
+       -- in hash_file I switched the constant "512" to "sizeof(buf)" to be a bit safer
+       -- in SHA-1's test routine I fixed the string literal to say SHA-1 not sha1
+       -- Fixed a logical error in the CTR code which would make it skip the first IV value.  This means
+          the CTR code from v0.52 will be incompatible [binary wise] with previous releases but it makes more
+          sense this way.
+       -- Added {} braces for as many if/for/blocks of code I could find.  My rule is that every for/if/while/do block
+          must have {} braces around it.
+       -- made the rounds table in saferp_setup const [again for the ROM think about the ROM!]
+       -- fixed RC5 since it no longer requires rc5 to be registered in the lib.  It used to since the descriptors used to 
+          be part of the table...
+       -- the packet.c code now makes crypt_error literal string errors when an error occurs
+       -- cleaned up the SAFER+ key schedule to be a bit easier to read.
+       -- fixed a huge bug in Twofish with the TWOFISH_SMALL define.  Because I clean the stack now I had
+          changed the "g_func()" to be called indirectly.  I forgot to actually return the return of the Twofish
+          g_func() function which caused it not to work... [does now :-)]
+
+July 11th, 2002
+v0.51  -- Fixed a bug in SHA512/384 code for multi-block messages.
+       -- Added more test vectors to the SHA384/512 and TIGER hash functions
+       -- cleaned up the hash done routines to make more sense
+ 
+July 10th, 2002
+v0.50  -- Fixed yarrow.c so that the cipher/hash used would be registered.  Also fixed
+          a bug where the SAFER+ name was "safer" but should have been "safer+".
+       -- Added an element to the hash descriptors that gives the size of a block [sent into the compressor]
+       -- Cleaned up the support for HMAC's
+       -- Cleaned up the test vector routines to make the test vector data const.  This means on some platforms it will be
+          placed in ROM not RAM now.
+       -- Added MD4 code submited by Dobes Vandermeer (dobes@smartt.com)
+       -- Added "burn_stack" function [idea taken from another source of crypto code].  The idea is if a function has
+          alot of variables it will clean up better.  Functions like the ecb serpent and twofish code will now have their
+          stacks cleaned and the rest of the code is getting much more straightforward.
+       -- Added a hashing demo by Daniel Richards (kyhwana@world-net.co.nz)
+       -- I (Tom) modified some of the test vector routines to use more vectors ala Dobes style.
+          For example, the MD5/SHA1 code now uses all of the test vectors from the RFC/FIPS spec.
+       -- Fixed the register/unregister functions to properly report errors in crypt_error
+       -- Correctly updated yarrow code to remove a few unused variables.
+       -- Updated manual to fix a few erroneous examples.
+       -- Added section on Hash based Message Authentication Codes (HMAC) to the manual
+
+June 19th, 2002
+v0.46  -- Added in HMAC code from Dobes Vandermeer (dobes@smartt.com)
+
+June 8th, 2002
+v0.45  -- Fixed bug in rc5.c where if you called rc5_setup() before registering RC5 it would cause
+          undefined behaviour.
+       -- Fixed mycrypt_cfg.h to eliminate the 224 bit ECC key.
+       -- made the "default" makefile target have depends on mycrypt.h and mycrypt_cfg.h
+
+Apr 4th, 2002
+v0.44  -- Fixed bug in ecc.c::new_point() where if the initial malloc fails it would not catch it.
+
+Mar 22nd, 2002
+v0.43  -- Changed the ZLIB code over to the 1.1.4 code base to avoid the "double free" bug.  
+       -- Updated the GCC makefile not to use -O3 or -funroll-loops
+       -- Version tag in mycrypt.h has been updated :-)
+
+Mar 10th, 2002
+v0.42  -- The RNG code can now use /dev/urandom before trying /dev/random (J. Klapste)
+
+Mar 3rd, 2002
+v0.41  -- Added support to link and use ciphers at compile time.  This can greatly reduce the code size!
+       -- Added a demo to show off how small an application can get... 46kb!
+       -- Disastry pointed out that Blowfish is supposed to be high endian.
+       -- Made registry code for the PRNGs as well [now the smallest useable link is 43kb]
+
+Feb 11th, 2002
+v0.40  -- RSA signatures use [and check for] fixed padding scheme.
+       -- I'm developing in Linux now :-)
+       -- No more warnings from GCC 2.96
+
+Feb 5th, 2002
+v0.39  -- Updated the XTEA code to work in accordance with the XTEA design
+
+January 24th, 2002
+v0.38  -- CFB and OFB modes can now handle blocks of variable size like the CTR code
+       -- Wrote a wrapper around the memory compress functions in Zlib that act like the functions
+          in the rest of my crypto lib
+
+January 23rd, 2002
+v0.37  -- Added support code so that if a hash size and key size for a cipher don't match up they will
+          use the next lower key supported.  (mainly for the PK code).  So you can now use SHA-1 with
+          Twofish, etc...
+       -- Added more options for Twofish.  You can now tell it to use precomputed sboxes and MDS multiplications
+          This will speed up the TWOFISH_SMALL implementation by increasing the code size by 1024 bytes.
+       -- Fixed a bug in prime.c that would not use the correct table if you undefined SMALL_PRIME_TAB
+       -- Fixed all of the PK packet code to use the same header format [see packet.c].  This makes the PK code
+          binary wise incompatible with previous releases while the API has not changed at all.
+
+January 22nd, 2002
+v0.36  -- Corrections to the manual
+       -- Made a modification to Twofish which lets you build a "small ram" variant.  It requires
+          about 190 bytes of ram for the key storage compared to the 4,200 bytes the normal 
+          variant requires.
+       -- Reduced the stack space used in all of the PK routines.
+
+January 19th, 2002
+v0.35  -- If you removed the first hash or cipher from the library it wouldn't return an error if 
+          you used an ID=0 [i.e blowfish or sha256] in any routine.  Now it checks for that and will
+          return an error like it should
+       -- Merged in new routines from Clay Culver.  These routines are for the PK code so you can easily 
+          encode a symmetric key for multiple recipients.
+       -- Made the ecc and DH make_key() routines make secret keys of the same size as the keysize listed.
+          Originally I wanted to ensure that the keys were smaller than the order of the field used
+          However, the bias is so insignifcant using full sizes.  For example, with a ECC-192 key the order
+          is about 2^191.99, so instead I rounded down and used a 184-bit secret key.  Now I simply use a full 192-bit
+          key the code will work just the same except that some 192-bit keys will be duplicates which is not a big
+          deal since 1/2^192 is a very small bias!
+       -- Made the configuration a bit simpler and more exacting.  You can for example now select which DH or ECC
+          key settings you wish to support without including the data for all other key settings.  I put the #defines
+          in a new file called "mycrypt_cfg.h"
+       -- Configured "mpi-config.h" so its a bit more conservative with the memory required and code space used
+       -- Jason Klapste submitted bug fixes to the yarrow, hash and various other issues.  The yarrow code will now
+          use what ever remaining hash/cipher combo is left [after you #undef them] at build time.   He also suggested
+          a fix to remove unused structures from the symmetric_key and hash_state unions.
+       -- Made the CTR code handle variable length blocks better. It will buffer the encryption pad so you can
+          encrypt messages any size block at a time.
+       -- Simplified the yarrow code to take advantage of the new CTR code.
+       -- Added a 4096-bit DH key setting.  That took me about 36 hours to find!
+       -- Changed the base64 routines to use a real base64 encoding scheme.
+       -- Added in DH and ECC "encrypt_key()" functions.  They are still rather "beta"ish.
+       -- Added **Twofish** to the list of ciphers!
+
+January 18th, 2002
+v0.34  -- Added "sha512" to the list of hashes.  Produces a 512-bit message digest.  Note that with the current
+          padding with the rsa_sign() function you cannot use sha512 with a key less than 1536 bits for signatures.
+       -- Cleaned up the other hash functions to use the LOAD and STORE macros...
+
+January 17th, 2002
+v0.33  -- Made the lower limit on keysizes for RSA 1024 bits again because I realized that 768 bit keys wouldn't
+          work with the padding scheme and large symmetric keys.
+       -- Added information concerning the Zlib license to the manual
+       -- Added a 3072-bit key setting for the DH code.
+       -- Made the "find_xyz()" routines take "const char *" as per Clay Culver's suggestion.
+       -- Fixed an embarassing typo in the manual concerning the hashes.  Thank's Clay for finding it!
+       -- Fixed rand_prime() so that it makes primes bigger than the setting you give.  For example,
+          if you want a 1024-bit prime it would make a 1023-bit one.  Now it ensures that the prime
+          it makes is always greater than 2^(8n) (n == bytes in prime).  This doesn't have a huge
+          impact on security but I corrected it just the same.
+       -- Fixed the CTR routine to work on platforms where char != 8-bits 
+       -- Fixed sha1/sha256/md5/blowfish to not assume "unsigned long == 32-bits", Basically any operation with carries
+          I "AND" with 0xFFFFFFFF.  That forces only the lower 32-bits to have information in it.  On x86 platforms
+          most compilers optimize out the AND operation since its a nop.
+
+January 16th, 2002
+v0.32  -- Made Rijndael's setup function fully static so it is thread safe
+       -- Svante Seleborg suggested a cosmetic style fixup for aes.c, 
+          basically to remove some of the #defines to clean it up
+       -- Made the PK routines not export the ASCII version of the names of ciphers/hashes which makes
+          the PK message formats *incompatible* with previous releases.
+       -- Merge in Zlib :-)
+ 
+  
+January 15th, 2002
+v0.31  -- The RSA routines can now use CRT to speed up decryption/signatures.  The routines are backwards 
+          compatible with previous releases.
+       -- Fixed another bug that Svante Seleborg found.  Basically you could buffer-overrun the 
+          rsa_exptmod() function itself if you're not careful.  That's fixed now.  Fixed another bug in
+          rsa_exptmod() where if it knows the buffer you passed is too small it wouldn't free all used 
+          memory.       
+       -- improved the readability of the PK import/export functions
+       -- Added a fix to RSA.C by Clay Culver
+       -- Changed the CONST64 macro for MSVC to use the "unsigned __int64" type, e.g. "ui64" instead of "i64".
+
+January 14th, 2002
+v0.30  -- Major change to the Yarrow PRNG code, fixed a bug that Eugene Starokoltsev found.
+          Basically if you added entropy to the pool in small increments it could in fact
+          cancel out.  Now I hash the pool with the new data which is way smarter.
+
+January 12th, 2002
+v0.29  -- Added MPI code written by Svante Seleborg to the library.  This will make the PK code much
+          easier to follow and debug.  Actually I've already fixed a memory leak in dh_shared_secret().
+       -- Memory leaks found and correct in all three PK routines.  The leaks would occur when a bignum
+          operation fails so it wouldn't normally turn up in the course of a program
+       -- Fixed bugs in dh_key_size and ecc_key_size which would return garbage for invalid key idx'es
+
+January 11th, 2002
+v0.28  -- Cleaned up some code so that it doesn't assume "char == 8bits".  Mainly SAFER+ has been 
+          changed.
+       -- ***HUGE*** changes in the PK code.  I check all return values in the bignum code so if there
+          are errors [insufficient memory, etc..] it will be reported.  This makes the code fairly more
+          robust and likely to catch any errors.
+       -- Updated the is_prime() function to use a new prototype [it can return errors now] and it also
+          does trial divisions against more primes before the Rabin Miller steps
+       -- Added OFB, CFB and ECB generic wrappers for the symmetric ciphers to round out the implementations.
+       -- Added Xtea to the list of ciphers, to the best of my ability I have verified this implementation.
+          I should note that there is not alot of concrete information about the cipher.  "Ansi C" versions
+          I found did not address endianess and were not even portable!.  This code is portable and to the
+          best of my knowledge implements the Xtea algorithm as per the [short] X-Tea paper.
+       -- Reformated the manual to include the **FULL** source code optimized to be pritable.
+
+January 9th, 2002
+v0.27  -- Changed the char constants to numerical values.  It is backwards compatible and should work on
+          platforms where 'd' != 100 [for example].
+       -- Made a change to rand_prime() which takes the input length as a signed type so you can pass
+          a negative len to get a "3 mod 4" style prime... oops
+       -- changed the MSVC makefile to build with a warning level of three, no warnings!
+
+January 8th, 2002
+v0.26  -- updated SHA-256 to use ROR() for a rotate so 64-bit machines won't corrupt
+          the output
+       -- Changed #include <> to #include "" for local .h files as per Richard Heathfields' suggestions.
+       -- Fixed bug in MPI [well bug in MSVC] that compiled code incorrectly in mp_set_int()
+          I added a work around that catches the error and continues normally.
+
+January 8th, 2002
+v0.25  -- Added a stupid define so MSVC 6.00 can build the library.
+       -- Big thanks to sci.crypt and "Ajay K. Agrawal" for helping me port this to MSVC
+
+January 7th, 2002
+v0.24  -- Sped up Blowfish by unrolling and removing the swaps.
+       -- Made the code comply with more traditional ANSI C standards
+          Should compile with MSVC with less errors
+       -- moved the demos and documentation into their own directories
+          so you can easily build the library with other tool chains
+          by compiling the files in the root
+       -- converted functions with length of outputs to use 
+          "unsigned long" so 16-bit platforms will like this library more.
+
+January 5th, 2002
+v0.23  -- Fixed a small error in the MPI config it should build fine anywhere.
+
+January 4th, 2002
+v0.22  -- faster gf_mul() code
+       -- gf_shl() and gf_shr() are safe on 64-bit platforms now
+       -- Fixed an error in the hashes that Brian Gladman found.  
+          Basically if the message has exactly 56 bytes left to be 
+          compressed I handled them incorrectly.
+
+January 4th, 2002
+v0.21  -- sped up the ECC code by removing redundant divisions in the 
+          point add and double routines.  I also extract the bits more
+          efficiently in "ecc_mulmod()" now.
+       -- sped up [and documented] the rand_prime() function.  Now it just
+          makes a random integer and increments by two until a prime is found
+          This is faster since it doesn't require alot of calls to the PRNG and
+          it doesn't require loading huge integers over and over.  rand_prime()
+          can also make primes congruent to 3 mod 4 [i.e for a blum integer]
+       -- added a gf_sqrt() function that finds square roots in a GF(2^w) field
+       -- fixed a bug in gf_div() that would return the wrong results if the divisor had a greator
+          divisor than the dividend.
+
+January 4th, 2002
+v0.20  -- Added the fixed MPI back in so RSA and DH are much faster again
+
+v0.19  -- Updated the manual to reflect the fact that Brian Gladman wrote the AES and Serpent code.
+       -- DH, ECC and RSA signature/decryption functions check if the key is private
+       -- new DH signature/verification code works just like the RSA/ECC versions
+
+January 3rd, 2002
+v0.18  -- Added way more comments to each .C file 
+       -- fixed a bug in cbc_decrypt(pt, ct, key) where pt == ct [i.e same buffer]
+       -- fixed RC5 so it reads the default rounds out of the cipher_descriptor table
+       -- cleaned up ecc_export()
+       -- Cleaned up dh_import() and ecc_import() which also perform more 
+          error checking now
+       -- Fixed a serious flaw in rsa_import() with private keys.
+
+January 2nd, 2002
+v0.17  -- Fixed a bug in the random prime generator that fixes the wrong bits to one
+       -- ECC and DH code verify that the moduli and orders are in fact prime.  That 
+          slows down the test routines alot but what are you gonna do? 
+       -- Fixed a huge bug in the mp_exptmod() function which incorrectly calculates g^x mod p for some
+          values of p.  I replaced it with a slow function.  Once the author of MPI fixes his faster routine
+          I will switch back.
+  
+January 1st, 2002 [whoa new year!]
+v0.16  -- Improved GF division code that is faster.
+       -- documented the GF code
+
+December 31st, 2001
+v0.15  -- A 1792-bit and 2048-bit DH setting was added.  Took me all night to 
+          find a 1792 and 2048-bit strong prime but what the heck
+       -- Library now has polynomial-basis GF(2^w) routines I wrote myself.  Can be used to perform
+          ECC over GF(2^w) later on....
+       -- Fixed a bug with the defines that allows it to build in windows
+       
+December 30th, 2001
+v0.14  -- Fixed the xxx_encrypt() packet routines to make an IV of appropriate size 
+          for the cipher used.  It was defaulting to making a 256-bit IV...
+       -- base64_encode() now appends a NULL byte, um "duh" stupid mistake now fixed...
+       -- spell checked the manual again... :-)
+
+December 30th, 2001
+v0.13  -- Switching back to older copy of MPI since it works! arrg..
+       -- Added sign/verify functions for ECC
+       -- all signature verification routines default to invalid signatures.
+       -- Changed all calls to memset to zeromem.  Fixed up some buffer problems 
+          in other routines.  All calls to zeromem let the compiler determine the size
+          of the data to wipe.
+
+December 29th, 2001
+v0.12  -- Imported a new version of MPI [the bignum library] that should
+          be a bit more stable [if you want to write your own bignum
+          routines with the library that is...]
+       -- Manual has way more info
+       -- hash_file() clears stack now [like it should]
+       -- The artificial cap on the hash input size of 2^32 bits has been
+          removed.  Basically I was too lazy todo 64-bit math before
+          [don't ask why... I can't remember].  Anyways the hashes
+          support the size of 2^64 bits [if you ever use that many bits in a message
+          that's just wierd...]
+       -- The hashes now wipe the "hash_state" after the digest is computed.  This helps
+          prevent the internal state of the hash being leaked accidently [i.e stack problems]
+
+December 29th, 2001
+v0.11  -- Made #define's so you can trim the library down by removing
+          ciphers, hashs, modes of operation, prngs, and even PK algorithms
+          For example, the library with rijndael+ctr+sha1+ECC is 91KB compared
+          to the 246kb the full library takes.
+       -- Added ECC packet routines for encrypt/decrypt/sign/verify much akin to
+          the RSA packet routines.
+       -- ECC now compresses the public key, a ECC-192 public key takes 33 bytes 
+          for example....
+
+December 28th, 2001
+v0.10  -- going to restart the manual from scratch to make it more 
+          clear and professional
+       -- Added ECC over Z/pZ.  Basically provides as much as DH
+          except its faster since the numbers are smaller.  For example,
+          A comparable 256-bit ECC key provides as much security as expected
+          from a DH key over 1024-bits.
+       -- Cleaned up the DH code to not export the symbol "sets[]"
+       -- Fixed a bug in the DH code that would not make the correct size 
+          random string if you made the key short.  For instance if you wanted 
+          a 512-bit DH key it would make a 768-bit one but only make up 512-bits 
+          for the exponent... now it makes the full 768 bits [or whatever the case 
+          is]
+       -- Fixed another ***SERIOUS*** bug in the DH code that would default to 768-bit
+          keys by mistake.
+
+December 25th, 2001
+v0.09  -- Includes a demo program called file_crypt which shows off
+          how to use the library to make a command line tool which
+          allows the user to encode/decode a file with any
+          hash (on the passphrase) and cipher in CTR mode.
+       -- Switched everything to use typedef's now to clear up the code.
+       -- Added AES (128/192 and 256 bit key modes)
+
+December 24th, 2001
+v0.08  -- fixed a typo in the manual. MPI stores its bignums in
+          BIG endian not little.
+       -- Started adding a RNG to the library.  Right now it tries
+          to open /dev/random and if that fails it uses either the 
+          MS CSP or the clock drift RNG.  It also allows callbacks 
+          since the drift RNG is slow (about 3.5 bytes/sec)
+       -- the RNG can also automatically setup a PRNG as well now
+
+v0.07  -- Added basic DH routines sufficient to 
+          negotiate shared secrets 
+          [see the manual for a complete example!]
+       -- Fixed rsa_import to detect when the input
+          could be corrupt.  
+       -- added more to the manual.
+
+December 22nd, 2001
+v0.06  -- Fixed some formatting errors in 
+          the hash functions [just source code cleaning]
+       -- Fixed a typo in the error message for sha256 :-)
+       -- Fixed an error in base64_encode() that 
+          would fail to catch all buffer overruns
+       -- Test program times the RSA and symmetric cipher 
+          routines for kicks...
+       -- Added the "const" modifier to alot of routines to 
+          clear up the purpose of each function.
+       -- Changed the name of the library to "TomCrypt" 
+          following a suggestion from a sci.crypt reader....
+
+v0.05  -- Fixed the ROL/ROR macro to be safe on platforms 
+          where unsigned long is not 32-bits
+       -- I have added a bit more to the documentation 
+          manual "crypt.pdf" provided.
+       -- I have added a makefile for LCC-Win32.  It should be 
+          easy to port to other LCC platforms by changing a few lines.
+       -- Ran a spell checker over the manual.
+       -- Changed the header and library from "crypt" to "mycrypt" to not
+          clash with the *nix package "crypt".
+
+v0.04  -- Fixed a bug in the RC5,RC6,Blowfish key schedules
+          where if the key was not a multiple of 4 bytes it would
+          not get loaded correctly.
+
+December 21st, 2001
+
+v0.03  -- Added Serpent to the list of ciphers.
+
+v0.02  -- Changed RC5 to only allow 12 to 24 rounds
+       -- Added more to the manual.
+
+v0.01  -- We will call this the first version.

+\chapter{Introduction}
+\mysection{What is the LibTomCrypt?}
+LibTomCrypt is a portable ISO C cryptographic library meant to be a tool set for cryptographers who are 
+designing cryptosystems.  It supports symmetric ciphers, one-way hashes, pseudo-random number generators, 
+public key cryptography (via PKCS \#1 RSA, DH or ECCDH), and a plethora of support routines.  
+
+The library was designed such that new ciphers/hashes/PRNGs can be added at run-time and the existing API 
+(and helper API functions) are able to use the new designs automatically.  There exists self-check functions for each 
+block cipher and hash function to ensure that they compile and execute to the published design specifications.  The library 
+also performs extensive parameter error checking to prevent any number of run-time exploits or errors.
+
+\subsection{What the library IS for?}
+
+The library serves as a toolkit for developers who have to solve cryptographic problems.  Out of the box LibTomCrypt
+does not process SSL or OpenPGP messages, it doesn't read X.509 certificates, or write PEM encoded data.  It does, however,
+provide all of the tools required to build such functionality.  LibTomCrypt was designed to be a flexible library that 
+was not tied to any particular cryptographic problem.  
+
+\mysection{Why did I write it?}
+You may be wondering, \textit{Tom, why did you write a crypto library.  I already have one.}  Well the reason falls into
+two categories:
+\begin{enumerate}
+    \item I am too lazy to figure out someone else's API.  I'd rather invent my own simpler API and use that.
+    \item It was (still is) good coding practice.
+\end{enumerate}
+
+The idea is that I am not striving to replace OpenSSL or Crypto++ or Cryptlib or etc.  I'm trying to write my 
+{\bf own} crypto library and hopefully along the way others will appreciate the work.
+
+With this library all core functions (ciphers, hashes, prngs, and bignum) have the same prototype definition.  They all load
+and store data in a format independent of the platform.  This means if you encrypt with Blowfish on a PPC it should decrypt
+on an x86 with zero problems.  The consistent API also means that if you learn how to use Blowfish with the library you 
+know how to use Safer+, RC6, or Serpent as well.  With all of the core functions there are central descriptor tables 
+that can be used to make a program automatically pick between ciphers, hashes and PRNGs at run-time.  That means your 
+application can support all ciphers/hashes/prngs/bignum without changing the source code.
+
+Not only did I strive to make a consistent and simple API to work with but I also attempted to make the library
+configurable in terms of its build options.  Out of the box the library will build with any modern version of GCC
+without having to use configure scripts.  This means that the library will work with platforms where development
+tools may be limited (e.g. no autoconf).
+
+On top of making the build simple and the API approachable I've also attempted for a reasonably high level of
+robustness and efficiency.  LibTomCrypt traps and returns a series of errors ranging from invalid
+arguments to buffer overflows/overruns.  It is mostly thread safe and has been clocked on various platforms
+with \textit{cycles per byte} timings that are comparable (and often favourable) to other libraries such as OpenSSL and
+Crypto++.
+
+\subsection{Modular}
+The LibTomCrypt package has also been written to be very modular.  The block ciphers, one--way hashes,
+pseudo--random number generators (PRNG), and bignum math routines are all used within the API through \textit{descriptor} tables which 
+are essentially structures with pointers to functions.  While you can still call particular functions
+directly (\textit{e.g. sha256\_process()}) this descriptor interface allows the developer to customize their
+usage of the library.
+
+For example, consider a hardware platform with a specialized RNG device.  Obviously one would like to tap
+that for the PRNG needs within the library (\textit{e.g. making a RSA key}).  All the developer has to do
+is write a descriptor and the few support routines required for the device.  After that the rest of the 
+API can make use of it without change.  Similarly imagine a few years down the road when AES2 
+(\textit{or whatever they call it}) has been invented.  It can be added to the library and used within applications 
+with zero modifications to the end applications provided they are written properly.
+
+This flexibility within the library means it can be used with any combination of primitive algorithms and 
+unlike libraries like OpenSSL is not tied to direct routines.  For instance, in OpenSSL there are CBC block
+mode routines for every single cipher.  That means every time you add or remove a cipher from the library
+you have to update the associated support code as well.  In LibTomCrypt the associated code (\textit{chaining modes in this case})
+are not directly tied to the ciphers.  That is a new cipher can be added to the library by simply providing 
+the key setup, ECB decrypt and encrypt and test vector routines.  After that all five chaining mode routines
+can make use of the cipher right away.
+
+\mysection{License}
+
+The project is hereby released as public domain.
+
+\mysection{Patent Disclosure}
+
+The author (Tom St Denis) is not a patent lawyer so this section is not to be treated as legal advice.  To the best
+of the authors knowledge the only patent related issues within the library are the RC5 and RC6 symmetric block ciphers.  
+They can be removed from a build by simply commenting out the two appropriate lines in \textit{tomcrypt\_custom.h}.  The rest
+of the ciphers and hashes are patent free or under patents that have since expired.
+
+The RC2 and RC4 symmetric ciphers are not under patents but are under trademark regulations.  This means you can use 
+the ciphers you just can't advertise that you are doing so.  
+

+\chapter{The Application Programming Interface (API)}
+\mysection{Introduction}
+\index{CRYPT\_ERROR} \index{CRYPT\_OK}
+
+In general the API is very simple to memorize and use.  Most of the functions return either {\bf void} or {\bf int}.  Functions
+that return {\bf int} will return {\bf CRYPT\_OK} if the function was successful, or one of the many error codes 
+if it failed.  Certain functions that return int will return $-1$ to indicate an error.  These functions will be explicitly
+commented upon.  When a function does return a CRYPT error code it can be translated into a string with
+
+\index{error\_to\_string()}
+\begin{verbatim}
+const char *error_to_string(int err);
+\end{verbatim}
+
+An example of handling an error is:
+\begin{small}
+\begin{verbatim}
+void somefunc(void)
+{
+   int err;
+   
+   /* call a cryptographic function */
+   if ((err = some_crypto_function(...)) != CRYPT_OK) {
+      printf("A crypto error occurred, %s\n", error_to_string(err));
+      /* perform error handling */
+   }
+   /* continue on if no error occurred */
+}
+\end{verbatim}
+\end{small}
+
+There is no initialization routine for the library and for the most part the code is thread safe.  The only thread
+related issue is if you use the same symmetric cipher, hash or public key state data in multiple threads.  Normally
+that is not an issue.
+
+To include the prototypes for \textit{LibTomCrypt.a} into your own program simply include \textit{tomcrypt.h} like so:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void) {
+    return 0;
+}
+\end{verbatim}
+\end{small}
+
+The header file \textit{tomcrypt.h} also includes \textit{stdio.h}, \textit{string.h}, \textit{stdlib.h}, \textit{time.h} and \textit{ctype.h}.
+
+\mysection{Macros}
+
+There are a few helper macros to make the coding process a bit easier.  The first set are related to loading and storing
+32/64-bit words in little/big endian format.  The macros are:
+
+\index{STORE32L} \index{STORE64L} \index{LOAD32L} \index{LOAD64L} \index{STORE32H} \index{STORE64H} \index{LOAD32H} \index{LOAD64H} \index{BSWAP}

+\mysection{Functions with Variable Length Output}
+Certain functions such as (for example) \textit{rsa\_export()} give an output that is variable length.  To prevent buffer overflows you
+must pass it the length of the buffer where the output will be stored.  For example:
+\index{rsa\_export()} \index{error\_to\_string()} \index{variable length output}
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void) {
+    rsa_key key;
+    unsigned char buffer[1024];
+    unsigned long x;
+    int err;
+
+    /* ... Make up the RSA key somehow ... */
+
+    /* lets export the key, set x to the size of the 
+     * output buffer */
+    x = sizeof(buffer);
+    if ((err = rsa_export(buffer, &x, PK_PUBLIC, &key)) != CRYPT_OK) {
+       printf("Export error: %s\n", error_to_string(err));
+       return -1;
+    }
+    
+    /* if rsa_export() was successful then x will have 
+     * the size of the output */
+    printf("RSA exported key takes %d bytes\n", x);
+
+    /* ... do something with the buffer */
+
+    return 0;
+}
+\end{verbatim}
+\end{small}
+In the above example if the size of the RSA public key was more than 1024 bytes this function would return an error code
+indicating a buffer overflow would have occurred.  If the function succeeds, it stores the length of the output back into 
+\textit{x} so that the calling application will know how many bytes were used.
+
+As of v1.13, most functions will update your length on failure to indicate the size required by the function.  Not all functions
+support this so please check the source before you rely on it doing that.
+
+\mysection{Functions that need a PRNG}
+\index{Pseudo Random Number Generator} \index{PRNG}
+Certain functions such as \textit{rsa\_make\_key()} require a Pseudo Random Number Generator (PRNG).  These functions do not setup 
+the PRNG themselves so it is the responsibility of the calling function to initialize the PRNG before calling them.
+
+Certain PRNG algorithms do not require a \textit{prng\_state} argument (sprng for example).  The \textit{prng\_state} argument
+may be passed as \textbf{NULL} in such situations.
+
+\index{register\_prng()} \index{rsa\_make\_key()}
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void) {
+    rsa_key key;
+    int     err;
+
+    /* register the system RNG */
+    register_prng(&sprng_desc) 
+
+    /* make a 1024-bit RSA key with the system RNG */
+    if ((err = rsa_make_key(NULL, find_prng("sprng"), 1024/8, 65537, &key)) 
+        != CRYPT_OK) {
+       printf("make_key error: %s\n", error_to_string(err));
+       return -1;
+    }
+
+    /* use the key ... */
+
+    return 0;
+}
+\end{verbatim}
+\end{small}
+
+\mysection{Functions that use Arrays of Octets}
+Most functions require inputs that are arrays of the data type \textit{unsigned char}.  Whether it is a symmetric key, IV
+for a chaining mode or public key packet it is assumed that regardless of the actual size of \textit{unsigned char} only the
+lower eight bits contain data.  For example, if you want to pass a 256 bit key to a symmetric ciphers setup routine, you 
+must pass in (a pointer to) an array of 32 \textit{unsigned char} variables.  Certain routines (such as SAFER+) take 
+special care to work properly on platforms where an \textit{unsigned char} is not eight bits.
+
+For the purposes of this library, the term \textit{byte} will refer to an octet or eight bit word.  Typically an array of
+type \textit{byte} will be synonymous with an array of type \textit{unsigned char.}
+
+\chapter{Symmetric Block Ciphers}
+\mysection{Core Functions}
+LibTomCrypt provides several block ciphers with an ECB block mode interface.  It is important to first note that you 
+should never use the ECB modes directly to encrypt data.  Instead you should use the ECB functions to make a chaining mode,
+or use one of the provided chaining modes.  All of the ciphers are written as ECB interfaces since it allows the rest of
+the API to grow in a modular fashion.
+
+\subsection{Key Scheduling}
+All ciphers store their scheduled keys in a single data type called \textit{symmetric\_key}.  This allows all ciphers to 
+have the same prototype and store their keys as naturally as possible.  This also removes the need for dynamic memory
+allocation, and allows you to allocate a fixed sized buffer for storing scheduled keys.  All ciphers must provide six visible 
+functions which are (given that XXX is the name of the cipher) the following:
+\index{Cipher Setup}
+\begin{verbatim}
+int XXX_setup(const unsigned char *key, 
+                              int  keylen, 
+                              int  rounds,
+                    symmetric_key *skey);
+\end{verbatim}
+
+The XXX\_setup() routine will setup the cipher to be used with a given number of rounds and a given key length (in bytes).
+The number of rounds can be set to zero to use the default, which is generally a good idea.
+
+If the function returns successfully the variable \textit{skey} will have a scheduled key stored in it.  It's important to note
+that you should only used this scheduled key with the intended cipher.  For example, if you call \textit{blowfish\_setup()} do not 
+pass the scheduled key onto \textit{rc5\_ecb\_encrypt()}.  All built--in setup functions do not allocate memory off the heap so 
+when you are done with a key you can simply discard it (e.g. they can be on the stack).  However, to maintain proper coding
+practices you should always call the respective XXX\_done() function.  This allows for quicker porting to applications with
+externally supplied plugins.
+
+\subsection{ECB Encryption and Decryption}
+To encrypt or decrypt a block in ECB mode there are these two functions per cipher:
+\index{Cipher Encrypt} \index{Cipher Decrypt}
+\begin{verbatim}
+int XXX_ecb_encrypt(const unsigned char *pt, 
+                          unsigned char *ct,
+                          symmetric_key *skey);
+
+int XXX_ecb_decrypt(const unsigned char *ct, 
+                          unsigned char *pt,
+                          symmetric_key *skey);
+\end{verbatim}
+These two functions will encrypt or decrypt (respectively) a single block of text\footnote{The size of which depends on
+which cipher you are using.}, storing the result in the \textit{ct} buffer (\textit{pt} resp.).  It is possible that the input and output buffer are 
+the same buffer.  For the encrypt function \textit{pt}\footnote{pt stands for plaintext.} is the input and 
+\textit{ct}\footnote{ct stands for ciphertext.} is the output.  For the decryption function it's the opposite.  They both
+return \textbf{CRYPT\_OK} on success.  To test a particular cipher against test vectors\footnote{As published in their design papers.} 
+call the following self-test function.
+ 
+\subsection{Self--Testing}
+\index{Cipher Testing}
+\begin{verbatim}
+int XXX_test(void);
+\end{verbatim}
+This function will return {\bf CRYPT\_OK} if the cipher matches the test vectors from the design publication it is 
+based upon.  
+
+\subsection{Key Sizing}
+For each cipher there is a function which will help find a desired key size.  It is specified as follows:
+\index{Key Sizing}
+\begin{verbatim}
+int XXX_keysize(int *keysize);
+\end{verbatim}
+Essentially, it will round the input keysize in \textit{keysize} down to the next appropriate key size.  This function
+will return {\bf CRYPT\_OK} if the key size specified is acceptable.  For example:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int keysize, err;
+
+   /* now given a 20 byte key what keysize does Twofish want to use? */
+   keysize = 20;
+   if ((err = twofish_keysize(&keysize)) != CRYPT_OK) {
+      printf("Error getting key size: %s\n", error_to_string(err));
+      return -1;
+   }
+   printf("Twofish suggested a key size of %d\n", keysize);
+   return 0;
+}
+\end{verbatim}
+\end{small}
+This should indicate a keysize of sixteen bytes is suggested by storing 16 in \textit{keysize.}
+
+\subsection{Cipher Termination}
+When you are finished with a cipher you can de--initialize it with the done function.
+\begin{verbatim}
+void XXX_done(symmetric_key *skey);
+\end{verbatim}
+For the software based ciphers within LibTomCrypt, these functions will not do anything.  However, user supplied
+cipher descriptors may require to be called for resource management purposes.  To be compliant, all functions which call a cipher
+setup function must also call the respective cipher done function when finished.
+
+\subsection{Simple Encryption Demonstration}
+An example snippet that encodes a block with Blowfish in ECB mode.
+
+\index{blowfish\_setup()} \index{blowfish\_ecb\_encrypt()} \index{blowfish\_ecb\_decrypt()} \index{blowfish\_done()}
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{ 
+   unsigned char pt[8], ct[8], key[8];
+   symmetric_key skey;
+   int err;
+
+   /* ... key is loaded appropriately in key ... */
+   /* ... load a block of plaintext in pt ... */
+
+   /* schedule the key */
+   if ((err = blowfish_setup(key, /* the key we will use */
+                               8, /* key is 8 bytes (64-bits) long */
+                               0, /* 0 == use default # of rounds */
+                           &skey) /* where to put the scheduled key */
+       ) != CRYPT_OK) {
+      printf("Setup error: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* encrypt the block */
+   blowfish_ecb_encrypt(pt,       /* encrypt this 8-byte array */
+                        ct,       /* store encrypted data here */ 
+                        &skey);   /* our previously scheduled key */
+                        
+   /* now ct holds the encrypted version of pt */                        
+
+   /* decrypt the block */
+   blowfish_ecb_decrypt(ct,       /* decrypt this 8-byte array */
+                        pt,       /* store decrypted data here */
+                        &skey);   /* our previously scheduled key */
+
+   /* now we have decrypted ct to the original plaintext in pt */                        
+
+   /* Terminate the cipher context */
+   blowfish_done(&skey);
+
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+\mysection{Key Sizes and Number of Rounds}
+\index{Symmetric Keys}
+As a general rule of thumb, do not use symmetric keys under 80 bits if you can help it.  Only a few of the ciphers support smaller
+keys (mainly for test vectors anyways).  Ideally, your application should be making at least 256 bit keys.  This is not
+because you are to be paranoid.  It is because if your PRNG has a bias of any sort the more bits the better.  For
+example, if you have $\mbox{Pr}\left[X = 1\right] = {1 \over 2} \pm \gamma$ where $\vert \gamma \vert > 0$ then the
+total amount of entropy in N bits is $N \cdot -log_2\left ({1 \over 2} + \vert \gamma \vert \right)$.  So if $\gamma$
+were $0.25$ (a severe bias) a 256-bit string would have about 106 bits of entropy whereas a 128-bit string would have
+only 53 bits of entropy.
+
+The number of rounds of most ciphers is not an option you can change.  Only RC5 allows you to change the number of
+rounds.  By passing zero as the number of rounds all ciphers will use their default number of rounds.  Generally the
+ciphers are configured such that the default number of rounds provide adequate security for the given block and key 
+size.
+
+\mysection{The Cipher Descriptors}
+\index{Cipher Descriptor}
+To facilitate automatic routines an array of cipher descriptors is provided in the array \textit{cipher\_descriptor}.  An element
+of this array has the following (partial) format (See Section \ref{sec:cipherdesc}):
+
+\begin{small}
+\begin{verbatim}
+struct _cipher_descriptor {
+   /** name of cipher */
+   char *name;
+
+   /** internal ID */
+   unsigned char ID;
+
+   /** min keysize (octets) */
+   int  min_key_length, 
+
+   /** max keysize (octets) */
+        max_key_length, 
+
+   /** block size (octets) */
+        block_length, 
+
+   /** default number of rounds */
+        default_rounds;
+...<snip>...
+};
+\end{verbatim}
+\end{small}
+
+Where \textit{name} is the lower case ASCII version of the name.  The fields \textit{min\_key\_length} and \textit{max\_key\_length} 
+are the minimum and maximum key sizes in bytes.  The \textit{block\_length} member is the block size of the cipher
+in bytes.  As a good rule of thumb it is assumed that the cipher supports
+the min and max key lengths but not always everything in between.  The \textit{default\_rounds} field is the default number
+of rounds that will be used.

+\subsection{Notes}
+\begin{small}
+\begin{enumerate}
+\item
+For AES, (also known as Rijndael) there are four descriptors which complicate issues a little.  The descriptors 
+rijndael\_desc and rijndael\_enc\_desc provide the cipher named \textit{rijndael}.  The descriptors aes\_desc and 
+aes\_enc\_desc provide the cipher name \textit{aes}.  Functionally both \textit{rijndael} and \textit{aes} are the same cipher.  The
+only difference is when you call find\_cipher() you have to pass the correct name.  The cipher descriptors with \textit{enc} 
+in the middle (e.g. rijndael\_enc\_desc) are related to an implementation of Rijndael with only the encryption routine
+and tables.  The decryption and self--test function pointers of both \textit{encrypt only} descriptors are set to \textbf{NULL} and 
+should not be called.
+
+The \textit{encrypt only} descriptors are useful for applications that only use the encryption function of the cipher.  Algorithms such
+as EAX, PMAC and OMAC only require the encryption function.  So far this \textit{encrypt only} functionality has only been implemented for
+Rijndael as it makes the most sense for this cipher.
+
+\item
+Note that for \textit{DES} and \textit{3DES} they use 8 and 24 byte keys but only 7 and 21 [respectively] bytes of the keys are in
+fact used for the purposes of encryption.  My suggestion is just to use random 8/24 byte keys instead of trying to make a 8/24
+byte string from the real 7/21 byte key.
+
+\item
+Note that \textit{Twofish} has additional configuration options (Figure \ref{fig:twofishopts}) that take place at build time.  These options are found in
+the file \textit{tomcrypt\_cfg.h}.  The first option is \textit{TWOFISH\_SMALL} which when defined will force the Twofish code
+to not pre-compute the Twofish \textit{$g(X)$} function as a set of four $8 \times 32$ s-boxes.  This means that a scheduled
+key will require less ram but the resulting cipher will be slower.  The second option is \textit{TWOFISH\_TABLES} which when
+defined will force the Twofish code to use pre-computed tables for the two s-boxes $q_0, q_1$ as well as the multiplication
+by the polynomials 5B and EF used in the MDS multiplication.  As a result the code is faster and slightly larger.  The
+speed increase is useful when \textit{TWOFISH\_SMALL} is defined since the s-boxes and MDS multiply form the heart of the
+Twofish round function.

+
+To work with the cipher\_descriptor array there is a function:
+\index{find\_cipher()}
+\begin{verbatim}
+int find_cipher(char *name)
+\end{verbatim}
+Which will search for a given name in the array.  It returns $-1$ if the cipher is not found, otherwise it returns
+the location in the array where the cipher was found.  For example, to indirectly setup Blowfish you can also use:
+\begin{small}
+\index{register\_cipher()} \index{find\_cipher()} \index{error\_to\_string()}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   unsigned char key[8];
+   symmetric_key skey;
+   int err;
+
+   /* you must register a cipher before you use it */
+   if (register_cipher(&blowfish_desc)) == -1) {
+      printf("Unable to register Blowfish cipher.");
+      return -1;
+   }
+
+   /* generic call to function (assuming the key 
+    * in key[] was already setup) */
+   if ((err = 
+        cipher_descriptor[find_cipher("blowfish")].
+          setup(key, 8, 0, &skey)) != CRYPT_OK) {
+      printf("Error setting up Blowfish: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* ... use cipher ... */
+}
+\end{verbatim}
+\end{small}
+
+A good safety would be to check the return value of \textit{find\_cipher()} before accessing the desired function.  In order
+to use a cipher with the descriptor table you must register it first using:
+\index{register\_cipher()}
+\begin{verbatim}
+int register_cipher(const struct _cipher_descriptor *cipher);
+\end{verbatim}
+Which accepts a pointer to a descriptor and returns the index into the global descriptor table.  If an error occurs such
+as there is no more room (it can have 32 ciphers at most) it will return {\bf{-1}}.  If you try to add the same cipher more
+than once it will just return the index of the first copy.  To remove a cipher call:
+\index{unregister\_cipher()}
+\begin{verbatim}
+int unregister_cipher(const struct _cipher_descriptor *cipher);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if it removes the cipher, otherwise it returns {\bf CRYPT\_ERROR}.  
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int err;
+   
+   /* register the cipher */
+   if (register_cipher(&rijndael_desc) == -1) {
+      printf("Error registering Rijndael\n");
+      return -1;
+   }
+
+   /* use Rijndael */
+
+   /* remove it */
+   if ((err = unregister_cipher(&rijndael_desc)) != CRYPT_OK) {
+      printf("Error removing Rijndael: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   return 0;
+}
+\end{verbatim}
+\end{small}
+This snippet is a small program that registers Rijndael.  
+
+\mysection{Symmetric Modes of Operations}
+\subsection{Background}
+A typical symmetric block cipher can be used in chaining modes to effectively encrypt messages larger than the block
+size of the cipher.  Given a key $k$, a plaintext $P$ and a cipher $E$ we shall denote the encryption of the block
+$P$ under the key $k$ as $E_k(P)$.  In some modes there exists an initial vector denoted as $C_{-1}$.
+
+\subsubsection{ECB Mode}
+\index{ECB mode}
+ECB or Electronic Codebook Mode is the simplest method to use.  It is given as:
+\begin{equation}
+C_i = E_k(P_i)
+\end{equation}
+This mode is very weak since it allows people to swap blocks and perform replay attacks if the same key is used more
+than once.
+
+\subsubsection{CBC Mode}
+\index{CBC mode}
+CBC or Cipher Block Chaining mode is a simple mode designed to prevent trivial forms of replay and swap attacks on ciphers.
+It is given as:
+\begin{equation}
+C_i = E_k(P_i \oplus C_{i - 1})
+\end{equation}
+It is important that the initial vector be unique and preferably random for each message encrypted under the same key.
+
+\subsubsection{CTR Mode}
+\index{CTR mode}
+CTR or Counter Mode is a mode which only uses the encryption function of the cipher.  Given a initial vector which is
+treated as a large binary counter the CTR mode is given as:
+\begin{eqnarray}
+C_{-1} = C_{-1} + 1\mbox{ }(\mbox{mod }2^W) \nonumber \\
+C_i = P_i \oplus E_k(C_{-1})
+\end{eqnarray}
+Where $W$ is the size of a block in bits (e.g. 64 for Blowfish).  As long as the initial vector is random for each message
+encrypted under the same key replay and swap attacks are infeasible.  CTR mode may look simple but it is as secure
+as the block cipher is under a chosen plaintext attack (provided the initial vector is unique).
+
+\subsubsection{CFB Mode}
+\index{CFB mode}
+CFB or Ciphertext Feedback Mode is a mode akin to CBC.  It is given as:
+\begin{eqnarray}
+C_i = P_i \oplus C_{-1} \nonumber \\
+C_{-1} = E_k(C_i)
+\end{eqnarray}
+Note that in this library the output feedback width is equal to the size of the block cipher.  That is this mode is used
+to encrypt whole blocks at a time.  However, the library will buffer data allowing the user to encrypt or decrypt partial
+blocks without a delay.  When this mode is first setup it will initially encrypt the initial vector as required.
+
+\subsubsection{OFB Mode}
+\index{OFB mode}
+OFB or Output Feedback Mode is a mode akin to CBC as well.  It is given as:
+\begin{eqnarray}
+C_{-1} = E_k(C_{-1}) \nonumber \\
+C_i = P_i \oplus C_{-1}
+\end{eqnarray}
+Like the CFB mode the output width in CFB mode is the same as the width of the block cipher.  OFB mode will also
+buffer the output which will allow you to encrypt or decrypt partial blocks without delay.
+
+\subsection{Choice of Mode}
+My personal preference is for the CTR mode since it has several key benefits:
+\begin{enumerate}
+   \item No short cycles which is possible in the OFB and CFB modes.
+   \item Provably as secure as the block cipher being used under a chosen plaintext attack.
+   \item Technically does not require the decryption routine of the cipher.
+   \item Allows random access to the plaintext.
+   \item Allows the encryption of block sizes that are not equal to the size of the block cipher.
+\end{enumerate}
+The CTR, CFB and OFB routines provided allow you to encrypt block sizes that differ from the ciphers block size.  They 
+accomplish this by buffering the data required to complete a block.  This allows you to encrypt or decrypt any size 
+block of memory with either of the three modes.
+
+The ECB and CBC modes process blocks of the same size as the cipher at a time.  Therefore, they are less flexible than the
+other modes.
+
+\subsection{Ciphertext Stealing}
+\index{Ciphertext stealing}
+Ciphertext stealing is a method of dealing with messages in CBC mode which are not a multiple of the block length.  This is accomplished
+by encrypting the last ciphertext block in ECB mode, and XOR'ing the output against the last partial block of plaintext.  LibTomCrypt does not
+support this mode directly but it is fairly easy to emulate with a call to the cipher's ecb\_encrypt() callback function.  
+
+The more sane way to deal with partial blocks is to pad them with zeroes, and then use CBC normally.  
+
+\subsection{Initialization}
+\index{CBC Mode} \index{CTR Mode}
+\index{OFB Mode} \index{CFB Mode}
+The library provides simple support routines for handling CBC, CTR, CFB, OFB and ECB encoded messages.  Assuming the mode 
+you want is XXX there is a structure called \textit{symmetric\_XXX} that will contain the information required to
+use that mode.  They have identical setup routines (except CTR and ECB mode):
+\index{ecb\_start()} \index{cfb\_start()} \index{cbc\_start()} \index{ofb\_start()} \index{ctr\_start()}
+\begin{verbatim}
+int XXX_start(                int  cipher, 
+              const unsigned char *IV, 
+              const unsigned char *key, 
+                              int  keylen, 
+                              int  num_rounds, 
+                    symmetric_XXX *XXX);
+
+int ctr_start(                int  cipher,
+              const unsigned char *IV,
+              const unsigned char *key, 
+                              int  keylen,
+                              int  num_rounds, 
+                              int  ctr_mode,
+                    symmetric_CTR *ctr);
+
+int ecb_start(                int  cipher, 
+              const unsigned char *key, 
+                              int  keylen, 
+                              int  num_rounds, 
+                    symmetric_ECB *ecb);
+\end{verbatim}
+
+In each case, \textit{cipher} is the index into the cipher\_descriptor array of the cipher you want to use.  The \textit{IV} value is 
+the initialization vector to be used with the cipher.  You must fill the IV yourself and it is assumed they are the same 
+length as the block size\footnote{In other words the size of a block of plaintext for the cipher, e.g. 8 for DES, 16 for AES, etc.} 
+of the cipher you choose.  It is important that the IV  be random for each unique message you want to encrypt.  The 
+parameters \textit{key}, \textit{keylen} and \textit{num\_rounds} are the same as in the XXX\_setup() function call.  The final parameter 
+is a pointer to the structure you want to hold the information for the mode of operation.
+
+
+In the case of CTR mode there is an additional parameter \textit{ctr\_mode} which specifies the mode that the counter is to be used in.
+If \textbf{CTR\_COUNTER\_ LITTLE\_ENDIAN} was specified then the counter will be treated as a little endian value.  Otherwise, if 
+\textbf{CTR\_COUNTER\_BIG\_ENDIAN} was specified the counter will be treated as a big endian value.  As of v1.15 the RFC 3686 style of
+increment then encrypt is also supported.  By OR'ing \textbf{LTC\_CTR\_RFC3686} with the CTR \textit{mode} value, ctr\_start() will increment
+the counter before encrypting it for the first time.
+
+The routines return {\bf CRYPT\_OK} if the cipher initialized correctly, otherwise, they return an error code.  
+
+\subsection{Encryption and Decryption}
+To actually encrypt or decrypt the following routines are provided:
+\index{ecb\_encrypt()} \index{ecb\_decrypt()} \index{cfb\_encrypt()} \index{cfb\_decrypt()} 
+\index{cbc\_encrypt()} \index{cbc\_decrypt()} \index{ofb\_encrypt()} \index{ofb\_decrypt()} \index{ctr\_encrypt()} \index{ctr\_decrypt()}
+\begin{verbatim}
+int XXX_encrypt(const unsigned char *pt, 
+                      unsigned char *ct, 
+                      unsigned long  len, 
+                      symmetric_YYY *YYY);
+
+int XXX_decrypt(const unsigned char *ct, 
+                      unsigned char *pt, 
+                      unsigned long  len, 
+                      symmetric_YYY *YYY);
+\end{verbatim}
+Where \textit{XXX} is one of $\lbrace ecb, cbc, ctr, cfb, ofb \rbrace$.  
+
+In all cases, \textit{len} is the size of the buffer (as number of octets) to encrypt or decrypt.  The CTR, OFB and CFB modes are order sensitive but not
+chunk sensitive.  That is you can encrypt \textit{ABCDEF} in three calls like \textit{AB}, \textit{CD}, \textit{EF} or two like \textit{ABCDE} and \textit{F}
+and end up with the same ciphertext.  However, encrypting \textit{ABC} and \textit{DABC} will result in different ciphertexts.  All
+five of the modes will return {\bf CRYPT\_OK} on success from the encrypt or decrypt functions.
+
+In the ECB and CBC cases, \textit{len} must be a multiple of the ciphers block size.  In the CBC case, you must manually pad the end of your message (either with
+zeroes or with whatever your protocol requires).
+
+To decrypt in either mode, perform the setup like before (recall you have to fetch the IV value you used), and use the decrypt routine on all of the blocks.
+
+\subsection{IV Manipulation}
+To change or read the IV of a previously initialized chaining mode use the following two functions.
+\index{cbc\_setiv()} \index{cbc\_getiv()} \index{ofb\_setiv()} \index{ofb\_getiv()} \index{cfb\_setiv()} \index{cfb\_getiv()}
+\index{ctr\_setiv()} \index{ctr\_getiv()}
+\begin{verbatim}
+int XXX_getiv(unsigned char *IV, 
+              unsigned long *len, 
+              symmetric_XXX *XXX);
+
+int XXX_setiv(const unsigned char *IV, 
+                    unsigned long  len, 
+                    symmetric_XXX *XXX);
+\end{verbatim}
+
+The XXX\_getiv() functions will read the IV out of the chaining mode and store it into \textit{IV} along with the length of the IV 
+stored in \textit{len}.  The XXX\_setiv will initialize the chaining mode state as if the original IV were the new IV specified.  The length
+of the IV passed in must be the size of the ciphers block size.
+
+The XXX\_setiv() functions are handy if you wish to change the IV without re--keying the cipher.  
+
+What the \textit{setiv} function will do depends on the mode being changed.  In CBC mode, the new IV replaces the existing IV as if it 
+were the last ciphertext block.  In CFB mode, the IV is encrypted as if it were the prior encrypted pad.  In CTR mode, the IV is encrypted without
+first incrementing it (regardless of the LTC\_RFC\_3686 flag presence).  In F8 mode, the IV is encrypted and becomes the new pad.  It does not change
+the salted IV, and is only meant to allow seeking within a session.  In LRW, it changes the tweak, forcing a computation of the tweak pad, allowing for
+seeking within the session.  In OFB mode, the IV is encrypted and becomes the new pad.
+
+\subsection{Stream Termination}
+To terminate an open stream call the done function.
+
+\index{ecb\_done()} \index{cbc\_done()}\index{cfb\_done()}\index{ofb\_done()} \index{ctr\_done()}
+\begin{verbatim}
+int XXX_done(symmetric_XXX *XXX);
+\end{verbatim}
+
+This will terminate the stream (by terminating the cipher) and return \textbf{CRYPT\_OK} if successful.
+

+\subsection{LRW Mode}
+LRW mode is a cipher mode which is meant for indexed encryption like used to handle storage media.  It is meant to have efficient seeking and overcome the 
+security problems of ECB mode while not increasing the storage requirements.  It is used much like any other chaining mode except with two key differences.
+
+The key is specified as two strings the first key $K_1$ is the (normally AES) key and can be any length (typically 16, 24 or 32 octets long).  The second key 
+$K_2$ is the \textit{tweak} key and is always 16 octets long.  The tweak value is \textbf{NOT} a nonce or IV value it must be random and secret.  
+
+To initialize LRW mode use:
+
+\index{lrw\_start()}
+\begin{verbatim}
+int lrw_start(                int  cipher,
+              const unsigned char *IV,
+              const unsigned char *key,       
+                              int  keylen,
+              const unsigned char *tweak,
+                              int  num_rounds, 
+                    symmetric_LRW *lrw);
+\end{verbatim}
+
+This will initialize the LRW context with the given (16 octet) \textit{IV}, cipher $K_1$ \textit{key} of length \textit{keylen} octets and the (16 octet) $K_2$ \textit{tweak}.  
+While LRW was specified to be used only with AES, LibTomCrypt will allow any 128--bit block cipher to be specified as indexed by \textit{cipher}.  The
+number of rounds for the block cipher \textit{num\_rounds} can be 0 to use the default number of rounds for the given cipher.
+
+To process data use the following functions:
+
+\index{lrw\_encrypt()} \index{lrw\_decrypt()}
+\begin{verbatim}
+int lrw_encrypt(const unsigned char *pt, 
+                      unsigned char *ct, 
+                      unsigned long  len, 
+                      symmetric_LRW *lrw);
+
+int lrw_decrypt(const unsigned char *ct, 
+                      unsigned char *pt, 
+                      unsigned long  len, 
+                      symmetric_LRW *lrw);
+\end{verbatim}
+
+These will encrypt (or decrypt) the plaintext to the ciphertext buffer (or vice versa).  The length is specified by \textit{len} in octets but must be a multiple
+of 16.  The LRW code uses a fast tweak update such that consecutive blocks are encrypted faster than if random seeking where used.  
+
+To manipulate the IV use the following functions:
+
+\index{lrw\_getiv()} \index{lrw\_setiv()} 
+\begin{verbatim}
+int lrw_getiv(unsigned char *IV, 
+              unsigned long *len, 
+              symmetric_LRW *lrw);
+
+int lrw_setiv(const unsigned char *IV, 
+                    unsigned long  len, 
+                    symmetric_LRW *lrw);
+\end{verbatim}
+These will get or set the 16--octet IV.  Note that setting the IV is the same as \textit{seeking} and unlike other modes is not a free operation.  It requires
+updating the entire tweak which is slower than sequential use.  Avoid seeking excessively in performance constrained code.
+
+To terminate the LRW state use the following:
+
+\index{lrw\_done()}
+\begin{verbatim}
+int lrw_done(symmetric_LRW *lrw);
+\end{verbatim}
+
+\subsection{F8 Mode}
+\index{F8 Mode}
+The F8 Chaining mode (see RFC 3711 for instance) is yet another chaining mode for block ciphers.  It behaves much like CTR mode in that it XORs a keystream
+against the plaintext to encrypt.  F8 mode comes with the additional twist that the counter value is secret, encrypted by a \textit{salt key}.  We
+initialize F8 mode with the following function call:
+
+\index{f8\_start()}
+\begin{verbatim}
+int f8_start(                int  cipher, 
+             const unsigned char *IV, 
+             const unsigned char *key,     
+                             int  keylen, 
+             const unsigned char *salt_key,               
+                             int  skeylen,
+                             int  num_rounds,   
+                    symmetric_F8 *f8);
+\end{verbatim}
+This will start the F8 mode state using \textit{key} as the secret key, \textit{IV} as the counter.  It uses the \textit{salt\_key} as IV encryption key 
+(\textit{m} in the RFC 3711).  The salt\_key can be shorter than the secret key but it should not be longer.  
+
+To encrypt or decrypt data we use the following two functions:
+
+\index{f8\_encrypt()} \index{f8\_decrypt()}
+\begin{verbatim}
+int f8_encrypt(const unsigned char *pt, 
+                     unsigned char *ct, 
+                     unsigned long  len, 
+                      symmetric_F8 *f8);
+
+int f8_decrypt(const unsigned char *ct, 
+                     unsigned char *pt, 
+                     unsigned long  len, 
+                      symmetric_F8 *f8);
+\end{verbatim}
+These will encrypt or decrypt a variable length array of bytes using the F8 mode state specified.  The length is specified in bytes and does not have to be a multiple 
+of the ciphers block size.
+
+To change or retrieve the current counter IV value use the following functions:
+\index{f8\_getiv()} \index{f8\_setiv()}
+\begin{verbatim}
+int f8_getiv(unsigned char *IV, 
+             unsigned long *len, 
+              symmetric_F8 *f8);
+
+int f8_setiv(const unsigned char *IV, 
+                   unsigned long  len, 
+                    symmetric_F8 *f8);
+\end{verbatim}
+These work with the current IV value only and not the encrypted IV value specified during the call to f8\_start().  The purpose of these two functions is to be
+able to seek within a current session only.  If you want to change the session IV you will have to call f8\_done() and then start a new state with
+f8\_start().
+
+To terminate an F8 state call the following function:
+
+\index{f8\_done()}
+\begin{verbatim}
+int f8_done(symmetric_F8 *f8);
+\end{verbatim}
+
+\vfil
+\mysection{Encrypt and Authenticate Modes}
+
+\subsection{EAX Mode}
+LibTomCrypt provides support for a mode called EAX\footnote{See 
+M. Bellare, P. Rogaway, D. Wagner, A Conventional Authenticated-Encryption Mode.} in a manner similar to the way it was intended to be used 
+by the designers.  First, a short description of what EAX mode is before we explain how to use it.  EAX is a mode that requires a cipher, 
+CTR and OMAC support and provides encryption and 
+authentication\footnote{Note that since EAX only requires OMAC and CTR you may use \textit{encrypt only} cipher descriptors with this mode.}.  
+It is initialized with a random \textit{nonce} that can be shared publicly, a \textit{header} which can be fixed and public, and a random secret symmetric key.
+
+The \textit{header} data is meant to be meta--data associated with a stream that isn't private (e.g., protocol messages).  It can
+be added at anytime during an EAX stream, and is part of the authentication tag.  That is, changes in the meta-data can be detected by changes in the output tag.
+
+The mode can then process plaintext producing ciphertext as well as compute a partial checksum.  The actual checksum
+called a \textit{tag} is only emitted when the message is finished.  In the interim, the user can process any arbitrary
+sized message block to send to the recipient as ciphertext.  This makes the EAX mode especially suited for streaming modes
+of operation.
+
+The mode is initialized with the following function.
+\index{eax\_init()}
+\begin{verbatim}
+int eax_init(          eax_state *eax, 
+                             int  cipher, 
+             const unsigned char *key, 
+                   unsigned long  keylen,
+             const unsigned char *nonce, 
+                   unsigned long  noncelen,
+             const unsigned char *header, 
+                   unsigned long  headerlen);
+\end{verbatim}
+
+Where \textit{eax} is the EAX state.  The \textit{cipher} parameter is the index of the desired cipher in the descriptor table.  
+The \textit{key} parameter is the shared secret symmetric key of length \textit{keylen} octets.  The \textit{nonce} parameter is the 
+random public string of length \textit{noncelen} octets.  The \textit{header} parameter is the random (or fixed or \textbf{NULL}) header for the 
+message of length \textit{headerlen} octets.
+
+When this function completes, the \textit{eax} state will be initialized such that you can now either have data decrypted or 
+encrypted in EAX mode.  Note: if \textit{headerlen} is zero you may pass \textit{header} as \textbf{NULL} to indicate there is no initial header data.
+
+To encrypt or decrypt data in a streaming mode use the following.
+\index{eax\_encrypt()} \index{eax\_decrypt()}
+\begin{verbatim}
+int eax_encrypt(          eax_state *eax, 
+                const unsigned char *pt, 
+                      unsigned char *ct, 
+                      unsigned long  length);
+
+int eax_decrypt(          eax_state *eax, 
+                const unsigned char *ct, 
+                      unsigned char *pt, 
+                      unsigned long  length);
+\end{verbatim}
+The function \textit{eax\_encrypt} will encrypt the bytes in \textit{pt} of \textit{length} octets, and store the ciphertext in
+\textit{ct}.  Note: \textit{ct} and \textit{pt} may be the same region in memory.   This function will also send the ciphertext
+through the OMAC function.  The function \textit{eax\_decrypt} decrypts \textit{ct}, and stores it in \textit{pt}.  This also allows 
+\textit{pt} and \textit{ct} to be the same region in memory.  
+
+You cannot both encrypt or decrypt with the same \textit{eax} context.  For bi--directional communication you will need to initialize 
+two EAX contexts (preferably with different headers and nonces).  
+
+Note: both of these functions allow you to send the data in any granularity but the order is important.  While
+the eax\_init() function allows you to add initial header data to the stream you can also add header data during the
+EAX stream with the following.
+
+\index{eax\_addheader()}
+\begin{verbatim}
+int eax_addheader(          eax_state *eax, 
+                  const unsigned char *header, 
+                        unsigned long  length);
+\end{verbatim}
+This will add the \textit{length} octet from \textit{header} to the given \textit{eax} header.  Once the message is finished, the 
+\textit{tag} (checksum) may be computed with the following function:
+
+\index{eax\_done()}
+\begin{verbatim}
+int eax_done(    eax_state *eax, 
+             unsigned char *tag, 
+             unsigned long *taglen);
+\end{verbatim}
+This will terminate the EAX state \textit{eax}, and store up to \textit{taglen} bytes of the message tag in \textit{tag}.  The function
+then stores how many bytes of the tag were written out back in to \textit{taglen}.
+
+The EAX mode code can be tested to ensure it matches the test vectors by calling the following function:
+\index{eax\_test()}
+\begin{verbatim}
+int eax_test(void);
+\end{verbatim}
+This requires that the AES (or Rijndael) block cipher be registered with the cipher\_descriptor table first.
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int           err;
+   eax_state     eax;
+   unsigned char pt[64], ct[64], nonce[16], key[16], tag[16];
+   unsigned long taglen;
+
+   if (register_cipher(&rijndael_desc) == -1) {
+      printf("Error registering Rijndael");
+      return EXIT_FAILURE;
+   }
+
+   /* ... make up random nonce and key ... */
+
+   /* initialize context */
+   if ((err = eax_init(            &eax,  /* context */
+                find_cipher("rijndael"),  /* cipher id */
+                                  nonce,  /* the nonce */
+                                     16,  /* nonce is 16 bytes */
+                              "TestApp",  /* example header */
+                                      7)  /* header length */
+       ) != CRYPT_OK) {
+      printf("Error eax_init: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* now encrypt data, say in a loop or whatever */
+   if ((err = eax_encrypt(     &eax, /* eax context */
+                                 pt, /* plaintext  (source) */
+                                 ct, /* ciphertext (destination) */
+                          sizeof(pt) /* size of plaintext */
+      ) != CRYPT_OK) {
+      printf("Error eax_encrypt: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* finish message and get authentication tag */
+   taglen = sizeof(tag);
+   if ((err = eax_done(   &eax,      /* eax context */
+                           tag,      /* where to put tag */
+                       &taglen       /* length of tag space */
+      ) != CRYPT_OK) {
+      printf("Error eax_done: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* now we have the authentication tag in "tag" and 
+    * it's taglen bytes long */
+}
+\end{verbatim}
+                       
+You can also perform an entire EAX state on a block of memory in a single function call with the 
+following functions.
+
+
+\index{eax\_encrypt\_authenticate\_memory} \index{eax\_decrypt\_verify\_memory}
+\begin{verbatim}
+int eax_encrypt_authenticate_memory(
+                    int  cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  unsigned long noncelen,
+    const unsigned char *header, unsigned long headerlen,
+    const unsigned char *pt,     unsigned long ptlen,
+          unsigned char *ct,
+          unsigned char *tag,    unsigned long *taglen);
+
+int eax_decrypt_verify_memory(
+                    int  cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  unsigned long noncelen,
+    const unsigned char *header, unsigned long headerlen,
+    const unsigned char *ct,     unsigned long ctlen,
+          unsigned char *pt,
+          unsigned char *tag,    unsigned long taglen,
+          int           *res);
+\end{verbatim}
+
+Both essentially just call eax\_init() followed by eax\_encrypt() (or eax\_decrypt() respectively) and eax\_done().  The parameters
+have the same meaning as with those respective functions.  
+
+The only difference is eax\_decrypt\_verify\_memory() does not emit a tag.  Instead you pass it a tag as input and it compares it against
+the tag it computed while decrypting the message.  If the tags match then it stores a $1$ in \textit{res}, otherwise it stores a $0$.
+
+\subsection{OCB Mode}
+LibTomCrypt provides support for a mode called OCB\footnote{See 
+P. Rogaway, M. Bellare, J. Black, T. Krovetz, \textit{OCB: A Block Cipher Mode of Operation for Efficient Authenticated Encryption}.}
+.  OCB is an encryption protocol that simultaneously provides authentication.  It is slightly faster to use than EAX mode
+but is less flexible.  Let's review how to initialize an OCB context.
+
+\index{ocb\_init()}
+\begin{verbatim}
+int ocb_init(          ocb_state *ocb, 
+                             int  cipher, 
+             const unsigned char *key, 
+                   unsigned long  keylen, 
+             const unsigned char *nonce);
+\end{verbatim}
+
+This will initialize the \textit{ocb} context using cipher descriptor \textit{cipher}.  It will use a \textit{key} of length \textit{keylen}
+and the random \textit{nonce}.  Note that \textit{nonce} must be a random (public) string the same length as the block ciphers
+block size (e.g. 16 bytes for AES).
+
+This mode has no \textit{Associated Data} like EAX mode does which means you cannot authenticate metadata along with the stream.
+To encrypt or decrypt data use the following.
+
+\index{ocb\_encrypt()} \index{ocb\_decrypt()}
+\begin{verbatim}
+int ocb_encrypt(          ocb_state *ocb, 
+                const unsigned char *pt, 
+                      unsigned char *ct);
+
+int ocb_decrypt(          ocb_state *ocb, 
+                const unsigned char *ct, 
+                      unsigned char *pt);
+\end{verbatim}
+
+This will encrypt (or decrypt for the latter) a fixed length of data from \textit{pt} to \textit{ct} (vice versa for the latter).  
+They assume that \textit{pt} and \textit{ct} are the same size as the block cipher's block size.  Note that you cannot call 
+both functions given a single \textit{ocb} state.  For bi-directional communication you will have to initialize two \textit{ocb}
+states (with different nonces).  Also \textit{pt} and \textit{ct} may point to the same location in memory.
+
+\subsubsection{State Termination}
+
+When you are finished encrypting the message you call the following function to compute the tag.
+
+\index{ocb\_done\_encrypt()}
+\begin{verbatim}
+int ocb_done_encrypt(          ocb_state *ocb, 
+                     const unsigned char *pt, 
+                           unsigned long  ptlen,
+                           unsigned char *ct, 
+                           unsigned char *tag, 
+                           unsigned long *taglen);
+\end{verbatim}
+
+This will terminate an encrypt stream \textit{ocb}.  If you have trailing bytes of plaintext that will not complete a block 
+you can pass them here.  This will also encrypt the \textit{ptlen} bytes in \textit{pt} and store them in \textit{ct}.  It will also
+store up to \textit{taglen} bytes of the tag into \textit{tag}.
+
+Note that \textit{ptlen} must be less than or equal to the block size of block cipher chosen.  Also note that if you have 
+an input message equal to the length of the block size then you pass the data here (not to ocb\_encrypt()) only.  
+
+To terminate a decrypt stream and compared the tag you call the following.
+
+\index{ocb\_done\_decrypt()}
+\begin{verbatim}
+int ocb_done_decrypt(          ocb_state *ocb, 
+                     const unsigned char *ct,  
+                           unsigned long  ctlen,
+                           unsigned char *pt, 
+                     const unsigned char *tag, 
+                           unsigned long  taglen, 
+                                     int *res);
+\end{verbatim}
+Similarly to the previous function you can pass trailing message bytes into this function.  This will compute the 
+tag of the message (internally) and then compare it against the \textit{taglen} bytes of \textit{tag} provided.  By default
+\textit{res} is set to zero.  If all \textit{taglen} bytes of \textit{tag} can be verified then \textit{res} is set to one (authenticated
+message).
+
+\subsubsection{Packet Functions}
+To make life simpler the following two functions are provided for memory bound OCB.
+
+%\index{ocb\_encrypt\_authenticate\_memory()}
+\begin{verbatim}
+int ocb_encrypt_authenticate_memory(
+                    int  cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  
+    const unsigned char *pt,     unsigned long ptlen,
+          unsigned char *ct,
+          unsigned char *tag,    unsigned long *taglen);
+\end{verbatim}
+
+This will OCB encrypt the message \textit{pt} of length \textit{ptlen}, and store the ciphertext in \textit{ct}.  The length \textit{ptlen}
+can be any arbitrary length.  
+
+\index{ocb\_decrypt\_verify\_memory()}
+\begin{verbatim}
+int ocb_decrypt_verify_memory(
+                    int  cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  
+    const unsigned char *ct,     unsigned long ctlen,
+          unsigned char *pt,
+    const unsigned char *tag,    unsigned long taglen,
+          int           *res);
+\end{verbatim}
+
+Similarly, this will OCB decrypt, and compare the internally computed tag against the tag provided. \textit{res} is set 
+appropriately.
+
+\subsection{CCM Mode}
+CCM is a NIST proposal for encrypt + authenticate that is centered around using AES (or any 16--byte cipher) as a primitive.  Unlike EAX and OCB mode,
+it is only meant for \textit{packet} mode where the length of the input is known in advance.  Since it is a packet mode function, CCM only has one 
+function that performs the protocol.
+
+\index{ccm\_memory()}
+\begin{verbatim}
+int ccm_memory(
+                    int  cipher,
+    const unsigned char *key,    unsigned long keylen,
+    symmetric_key       *uskey,
+    const unsigned char *nonce,  unsigned long noncelen,
+    const unsigned char *header, unsigned long headerlen,
+          unsigned char *pt,     unsigned long ptlen,
+          unsigned char *ct,
+          unsigned char *tag,    unsigned long *taglen,
+                    int  direction);
+\end{verbatim}
+
+This performs the \textit{CCM} operation on the data.  The \textit{cipher} variable indicates which cipher in the descriptor table to use.  It must have a 
+16--byte block size for CCM.  
+
+The key can be specified in one of two fashions.  First, it can be passed as an array of octets in \textit{key} of length \textit{keylen}.  Alternatively,
+it can be passed in as a previously scheduled key in \textit{uskey}.  The latter fashion saves time when the same key is used for multiple packets.  If
+\textit{uskey} is not \textbf{NULL}, then \textit{key} may be \textbf{NULL} (and vice-versa). 
+
+The nonce or salt is \textit{nonce} of length \textit{noncelen} octets.  The header is meta--data you want to send with the message but not have 
+encrypted, it is stored in \textit{header} of length \textit{headerlen} octets.  The header can be zero octets long (if $headerlen = 0$ then 
+you can pass \textit{header} as \textbf{NULL}).  
+
+The plaintext is stored in \textit{pt}, and the ciphertext in \textit{ct}.  The length of both are expected to be equal and is passed in as \textit{ptlen}.  It is
+allowable that $pt = ct$.  The \textit{direction} variable indicates whether encryption (direction $=$ \textbf{CCM\_ENCRYPT}) or 
+decryption (direction $=$ \textbf{CCM\_DECRYPT}) is to be performed.
+
+As implemented, this version of CCM cannot handle header or plaintext data longer than $2^{32} - 1$ octets long.  
+
+You can test the implementation of CCM with the following function.
+
+\index{ccm\_test()}
+\begin{verbatim}
+int ccm_test(void);
+\end{verbatim}
+
+This will return \textbf{CRYPT\_OK} if the CCM routine passes known test vectors.  It requires AES or Rijndael to be registered previously, otherwise it will
+return \textbf{CRYPT\_NOP}.
+
+\subsubsection{CCM Example}
+The following is a sample of how to call CCM.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   unsigned char key[16], nonce[12], pt[32], ct[32], 
+                 tag[16], tagcp[16];
+   unsigned long taglen;
+   int           err;
+
+   /* register cipher */
+   register_cipher(&aes_desc);
+
+   /* somehow fill key, nonce, pt */
+ 
+   /* encrypt it */
+   taglen = sizeof(tag);
+   if ((err = 
+       ccm_memory(find_cipher("aes"),
+                  key, 16,    /* 128-bit key */
+                  NULL,       /* not prescheduled */
+                  nonce, 12,  /* 96-bit nonce */
+                  NULL, 0,    /* no header */
+                  pt, 32,     /* 32-byte plaintext */
+                  ct,         /* ciphertext */
+                  tag, &taglen,
+                  CCM_ENCRYPT)) != CRYPT_OK) {
+       printf("ccm_memory error %s\n", error_to_string(err));
+       return -1;
+   }
+   /* ct[0..31] and tag[0..15] now hold the output */
+
+   /* decrypt it */
+   taglen = sizeof(tagcp);
+   if ((err = 
+       ccm_memory(find_cipher("aes"),
+                  key, 16,    /* 128-bit key */
+                  NULL,       /* not prescheduled */
+                  nonce, 12,  /* 96-bit nonce */
+                  NULL, 0,    /* no header */
+                  ct, 32,     /* 32-byte ciphertext */
+                  pt,         /* plaintext */
+                  tagcp, &taglen,
+                  CCM_DECRYPT)) != CRYPT_OK) {
+       printf("ccm_memory error %s\n", error_to_string(err));
+       return -1;
+   }
+
+   /* now pt[0..31] should hold the original plaintext,
+      tagcp[0..15] and tag[0..15] should have the same contents */
+}
+\end{verbatim}
+\end{small}
+
+\subsection{GCM Mode}
+Galois counter mode is an IEEE proposal for authenticated encryption (also it is a planned NIST standard).  Like EAX and OCB mode, it can be used in a streaming capacity 
+however, unlike EAX it cannot accept \textit{additional authentication data} (meta--data) after plaintext has been processed.  This mode also only works with 
+block ciphers with a 16--byte block.
+
+A GCM stream is meant to be processed in three modes, one after another.  First, the initial vector (per session) data is processed.  This should be 
+unique to every session.  Next, the the optional additional authentication data is processed, and finally the plaintext (or ciphertext depending on the direction).  
+
+\subsubsection{Initialization}
+To initialize the GCM context with a secret key call the following function.
+
+\index{gcm\_init()}
+\begin{verbatim}
+int gcm_init(          gcm_state *gcm, 
+                             int  cipher,
+             const unsigned char *key, 
+                             int  keylen);
+\end{verbatim}
+This initializes the GCM state \textit{gcm} for the given cipher indexed by \textit{cipher}, with a secret key \textit{key} of length \textit{keylen} octets.  The cipher 
+chosen must have a 16--byte block size (e.g., AES).  
+
+\subsubsection{Initial Vector}
+After the state has been initialized (or reset) the next step is to add the session (or packet) initial vector.  It should be unique per packet encrypted.
+
+\index{gcm\_add\_iv()}
+\begin{verbatim}
+int gcm_add_iv(          gcm_state *gcm, 
+               const unsigned char *IV,     
+                     unsigned long  IVlen);
+\end{verbatim}
+This adds the initial vector octets from \textit{IV} of length \textit{IVlen} to the GCM state \textit{gcm}.  You can call this function as many times as required
+to process the entire IV.  
+
+Note: the GCM protocols provides a \textit{shortcut} for 12--byte IVs where no pre-processing is to be done.  If you want to minimize per packet latency it is ideal
+to only use 12--byte IVs.  You can just increment it like a counter for each packet.
+
+\subsubsection{Additional Authentication Data}
+After the entire IV has been processed, the additional authentication data can be processed.  Unlike the IV, a packet/session does not require additional
+authentication data (AAD) for security.  The AAD is meant to be used as side--channel data you want to be authenticated with the packet.  Note:  once
+you begin adding AAD to the GCM state you cannot return to adding IV data until the state has been reset.
+
+\index{gcm\_add\_aad()}
+\begin{verbatim}
+int gcm_add_aad(          gcm_state *gcm, 
+                const unsigned char *adata, 
+                      unsigned long  adatalen);
+\end{verbatim}
+This adds the additional authentication data \textit{adata} of length \textit{adatalen} to the GCM state \textit{gcm}.
+
+\subsubsection{Plaintext Processing}
+After the AAD has been processed, the plaintext (or ciphertext depending on the direction) can be processed.  
+
+\index{gcm\_process()}
+\begin{verbatim}
+int gcm_process(    gcm_state *gcm,
+                unsigned char *pt, 
+                unsigned long  ptlen,
+                unsigned char *ct,
+                          int  direction);
+\end{verbatim}
+This processes message data where \textit{pt} is the plaintext and \textit{ct} is the ciphertext.  The length of both are equal and stored in \textit{ptlen}.  Depending on 
+the mode \textit{pt} is the input and \textit{ct} is the output (or vice versa).  When \textit{direction} equals \textbf{GCM\_ENCRYPT} the plaintext is read, 
+encrypted and stored in the ciphertext buffer.  When \textit{direction} equals \textbf{GCM\_DECRYPT} the opposite occurs.
+
+\subsubsection{State Termination}
+To terminate a GCM state and retrieve the message authentication tag call the following function.
+
+\index{gcm\_done()}
+\begin{verbatim}
+int gcm_done(    gcm_state *gcm, 
+             unsigned char *tag, 
+             unsigned long *taglen);
+\end{verbatim}
+This terminates the GCM state \textit{gcm} and stores the tag in \textit{tag} of length \textit{taglen} octets.
+
+\subsubsection{State Reset}
+The call to gcm\_init() will perform considerable pre--computation (when \textbf{GCM\_TABLES} is defined) and if you're going to be dealing with a lot of packets
+it is very costly to have to call it repeatedly.  To aid in this endeavour, the reset function has been provided.
+
+\index{gcm\_reset()}
+\begin{verbatim}
+int gcm_reset(gcm_state *gcm);
+\end{verbatim}
+
+This will reset the GCM state \textit{gcm} to the state that gcm\_init() left it.  The user would then call gcm\_add\_iv(), gcm\_add\_aad(), etc.
+
+\subsubsection{One--Shot Packet}
+To process a single packet under any given key the following helper function can be used.
+
+\index{gcm\_memory()}
+\begin{verbatim}
+int gcm_memory(      
+                    int  cipher,
+    const unsigned char *key,    
+          unsigned long keylen,
+    const unsigned char *IV,    unsigned long IVlen,
+    const unsigned char *adata, unsigned long adatalen,
+          unsigned char *pt,    unsigned long ptlen,
+          unsigned char *ct, 
+          unsigned char *tag,   unsigned long *taglen,
+                    int  direction);
+\end{verbatim}
+
+This will initialize the GCM state with the given key, IV and AAD value then proceed to encrypt or decrypt the message text and store the final
+message tag.  The definition of the variables is the same as it is for all the manual functions.
+
+If you are processing many packets under the same key you shouldn't use this function as it invokes the pre--computation with each call.
+
+\subsubsection{Example Usage}
+The following is an example usage of how to use GCM over multiple packets with a shared secret key.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+
+int send_packet(const unsigned char *pt,  unsigned long ptlen,
+                const unsigned char *iv,  unsigned long ivlen,
+                const unsigned char *aad, unsigned long aadlen,
+                      gcm_state     *gcm)
+{
+   int           err;
+   unsigned long taglen;
+   unsigned char tag[16];
+
+   /* reset the state */
+   if ((err = gcm_reset(gcm)) != CRYPT_OK) {
+      return err;
+   }
+ 
+   /* Add the IV */
+   if ((err = gcm_add_iv(gcm, iv, ivlen)) != CRYPT_OK) {
+      return err;
+   }
+
+   /* Add the AAD (note: aad can be NULL if aadlen == 0) */
+   if ((err = gcm_add_aad(gcm, aad, aadlen)) != CRYPT_OK) {
+      return err;
+   }
+
+   /* process the plaintext */
+   if ((err = 
+        gcm_process(gcm, pt, ptlen, pt, GCM_ENCRYPT)) != CRYPT_OK) {
+      return err;
+   }
+
+   /* Finish up and get the MAC tag */
+   taglen = sizeof(tag);
+   if ((err = gcm_done(gcm, tag, &taglen)) != CRYPT_OK) {
+      return err;
+   }
+
+   /* ... send a header describing the lengths ... */
+
+   /* depending on the protocol and how IV is 
+    * generated you may have to send it too... */
+   send(socket, iv, ivlen, 0);
+
+   /* send the aad */
+   send(socket, aad, aadlen, 0);
+
+   /* send the ciphertext */
+   send(socket, pt, ptlen, 0);
+
+   /* send the tag */
+   send(socket, tag, taglen, 0);
+
+   return CRYPT_OK;
+}
+
+int main(void)
+{
+   gcm_state     gcm;
+   unsigned char key[16], IV[12], pt[PACKET_SIZE];
+   int           err, x;
+   unsigned long ptlen; 
+ 
+   /* somehow fill key/IV with random values */
+   
+   /* register AES */
+   register_cipher(&aes_desc);
+
+   /* init the GCM state */
+   if ((err = 
+        gcm_init(&gcm, find_cipher("aes"), key, 16)) != CRYPT_OK) {
+      whine_and_pout(err);
+   }
+
+   /* handle us some packets */
+   for (;;) {
+       ptlen = make_packet_we_want_to_send(pt);
+
+       /* use IV as counter (12 byte counter) */
+       for (x = 11; x >= 0; x--) {
+           if (++IV[x]) {
+              break;
+           }
+       }
+
+       if ((err = send_packet(pt, ptlen, iv, 12, NULL, 0, &gcm)) 
+           != CRYPT_OK) {
+           whine_and_pout(err);
+       }
+   }
+   return EXIT_SUCCESS;
+}
+\end{verbatim}
+\end{small}
+
+\chapter{One-Way Cryptographic Hash Functions}
+\mysection{Core Functions}
+Like the ciphers, there are hash core functions and a universal data type to hold the hash state called \textit{hash\_state}.  To initialize hash 
+XXX (where XXX is the name) call:
+\index{Hash Functions}
+\begin{verbatim}
+void XXX_init(hash_state *md);
+\end{verbatim}
+
+This simply sets up the hash to the default state governed by the specifications of the hash.  To add data to the message being hashed call:
+\begin{verbatim}
+int XXX_process(         hash_state *md, 
+                const unsigned char *in, 
+                      unsigned long  inlen);
+\end{verbatim}
+Essentially all hash messages are virtually infinitely\footnote{Most hashes are limited to $2^{64}$ bits or 2,305,843,009,213,693,952 bytes.} long message which 
+are buffered.  The data can be passed in any sized chunks as long as the order of the bytes are the same the message digest (hash output) will be the same.  For example, 
+this means that:
+\begin{verbatim}
+md5_process(&md, "hello ", 6);
+md5_process(&md, "world", 5);
+\end{verbatim}
+Will produce the same message digest as the single call:
+\index{Message Digest}
+\begin{verbatim}
+md5_process(&md, "hello world", 11);
+\end{verbatim}
+
+To finally get the message digest (the hash) call:
+\begin{verbatim}
+int XXX_done(   hash_state *md, 
+             unsigned char *out);
+\end{verbatim}
+
+This function will finish up the hash and store the result in the \textit{out} array.  You must ensure that \textit{out} is long
+enough for the hash in question.  Often hashes are used to get keys for symmetric ciphers so the \textit{XXX\_done()} functions
+will wipe the \textit{md} variable before returning automatically.
+
+To test a hash function call:
+\begin{verbatim}
+int XXX_test(void);
+\end{verbatim}
+
+This will return {\bf CRYPT\_OK} if the hash matches the test vectors, otherwise it returns an error code.  An
+example snippet that hashes a message with md5 is given below.
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+    hash_state md;
+    unsigned char *in = "hello world", out[16];
+
+    /* setup the hash */
+    md5_init(&md);
+
+    /* add the message */
+    md5_process(&md, in, strlen(in));
+
+    /* get the hash in out[0..15] */
+    md5_done(&md, out);
+
+    return 0;
+}
+\end{verbatim}
+\end{small}
+
+\mysection{Hash Descriptors}
+Like the set of ciphers, the set of hashes have descriptors as well.  They are stored in an array called \textit{hash\_descriptor} and
+are defined by:
+\begin{verbatim}
+struct _hash_descriptor {
+    char *name;
+
+    unsigned long hashsize;    /* digest output size in bytes  */
+    unsigned long blocksize;   /* the block size the hash uses */
+
+    void (*init)   (hash_state *hash);
+
+    int  (*process)(         hash_state *hash, 
+                    const unsigned char *in, 
+                          unsigned long  inlen);
+
+    int  (*done)   (hash_state *hash, unsigned char *out);
+
+    int  (*test)   (void);
+};
+\end{verbatim}
+
+\index{find\_hash()}
+The \textit{name} member is the name of the hash function (all lowercase).  The \textit{hashsize} member is the size of the digest output
+in bytes, while \textit{blocksize} is the size of blocks the hash expects to the compression function.  Technically, this detail is not important
+for high level developers but is useful to know for performance reasons.  
+
+The \textit{init} member initializes the hash, \textit{process} passes data through the hash, \textit{done} terminates the hash and retrieves the 
+digest.  The \textit{test} member tests the hash against the specified test vectors.
+
+There is a function to search the array as well called \textit{int find\_hash(char *name)}.  It returns -1 if the hash is not found, otherwise, the
+position in the descriptor table of the hash.
+
+In addition, there is also find\_hash\_oid() which finds a hash by the ASN.1 OBJECT IDENTIFIER string.
+\index{find\_hash\_oid()}
+\begin{verbatim}
+int find_hash_oid(const unsigned long *ID, unsigned long IDlen);
+\end{verbatim}
+
+You can use the table to indirectly call a hash function that is chosen at run-time.  For example:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   unsigned char buffer[100], hash[MAXBLOCKSIZE];
+   int idx, x;
+   hash_state md;
+
+   /* register hashes .... */
+   if (register_hash(&md5_desc) == -1) {
+      printf("Error registering MD5.\n");
+      return -1;
+   }
+
+   /* register other hashes ... */
+
+   /* prompt for name and strip newline */
+   printf("Enter hash name: \n");
+   fgets(buffer, sizeof(buffer), stdin);
+   buffer[strlen(buffer) - 1] = 0;
+
+   /* get hash index */
+   idx = find_hash(buffer);
+   if (idx == -1) {
+      printf("Invalid hash name!\n");
+      return -1;
+   }
+
+   /* hash input until blank line */
+   hash_descriptor[idx].init(&md);
+   while (fgets(buffer, sizeof(buffer), stdin) != NULL)
+         hash_descriptor[idx].process(&md, buffer, strlen(buffer));
+   hash_descriptor[idx].done(&md, hash);
+
+   /* dump to screen */
+   for (x = 0; x < hash_descriptor[idx].hashsize; x++)
+       printf("%02x ", hash[x]);
+   printf("\n");
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+Note the usage of \textbf{MAXBLOCKSIZE}.  In LibTomCrypt, no symmetric block, key or hash digest is larger than \textbf{MAXBLOCKSIZE} in
+length.  This provides a simple size you can set your automatic arrays to that will not get overrun.
+
+There are three helper functions to make working with hashes easier.  The first is a function to hash a buffer, and produce the digest in a single
+function call.
+
+\index{hash\_memory()} 
+\begin{verbatim}
+int hash_memory(                int  hash, 
+                const unsigned char *in,   
+                      unsigned long  inlen, 
+                      unsigned char *out,  
+                      unsigned long *outlen);
+\end{verbatim}
+
+This will hash the data pointed to by \textit{in} of length \textit{inlen}.  The hash used is indexed by the \textit{hash} parameter.  The message
+digest is stored in \textit{out}, and the \textit{outlen} parameter is updated to hold the message digest size.  
+
+The next helper function allows for the hashing of a file based on a file name.  
+\index{hash\_file()}
+\begin{verbatim}
+int hash_file(          int  hash, 
+                 const char *fname, 
+              unsigned char *out, 
+              unsigned long *outlen);
+\end{verbatim}
+
+This will hash the file named by \textit{fname} using the hash indexed by \textit{hash}.  The file named in this function call must be readable by the 
+user owning the process performing the request.  This function can be omitted by the \textbf{LTC\_NO\_FILE} define, which forces it to return \textbf{CRYPT\_NOP}
+when it is called.  The message digest is stored in \textit{out}, and the \textit{outlen} parameter is updated to hold the message digest size.  
+
+\index{hash\_filehandle()}
+\begin{verbatim}
+int hash_filehandle(          int  hash, 
+                             FILE *in, 
+                    unsigned char *out, 
+                    unsigned long *outlen);
+\end{verbatim}
+
+This will hash the file identified by the handle \textit{in} using the hash indexed by \textit{hash}.  This will begin hashing from the current file pointer position, and
+will not rewind the file pointer when finished.  This function can be omitted by the \textbf{LTC\_NO\_FILE} define, which forces it to return \textbf{CRYPT\_NOP}
+when it is called.  The message digest is stored in \textit{out}, and the \textit{outlen} parameter is updated to hold the message digest size.  
+
+To perform the above hash with md5 the following code could be used:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int idx, err;
+   unsigned long len;
+   unsigned char out[MAXBLOCKSIZE];
+
+   /* register the hash */
+   if (register_hash(&md5_desc) == -1) {
+      printf("Error registering MD5.\n");
+      return -1;
+   }
+
+   /* get the index of the hash  */
+   idx = find_hash("md5");
+
+   /* call the hash */
+   len = sizeof(out);
+   if ((err = 
+       hash_memory(idx, "hello world", 11, out, &len)) != CRYPT_OK) {
+      printf("Error hashing data: %s\n", error_to_string(err));
+      return -1;
+   }
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+\subsection{Hash Registration}
+Similar to the cipher descriptor table you must register your hash algorithms before you can use them.  These functions
+work exactly like those of the cipher registration code.  The functions are:
+\index{register\_hash()} \index{unregister\_hash()}
+\begin{verbatim}
+int register_hash(const struct _hash_descriptor *hash);
+
+int unregister_hash(const struct _hash_descriptor *hash);
+\end{verbatim}
+
+The following hashes are provided as of this release within the LibTomCrypt library:
+\index{Hash descriptor table}

+\mysection{Cipher Hash Construction}
+\index{Cipher Hash Construction}
+An addition to the suite of hash functions is the \textit{Cipher Hash Construction} or \textit{CHC} mode.  In this mode
+applicable block ciphers (such as AES) can be turned into hash functions that other LTC functions can use.  In 
+particular this allows a cryptosystem to be designed using very few moving parts.
+
+In order to use the CHC system the developer will have to take a few extra steps.  First the \textit{chc\_desc} hash
+descriptor must be registered with register\_hash().  At this point the CHC hash cannot be used to hash
+data.  While it is in the hash system you still have to tell the CHC code which cipher to use.  This is accomplished
+via the chc\_register() function.
+
+\index{chc\_register()}
+\begin{verbatim}
+int chc_register(int cipher);
+\end{verbatim}
+
+A cipher has to be registered with CHC (and also in the cipher descriptor tables with 
+register\_cipher()).  The chc\_register() function will bind a cipher to the CHC system.  Only one cipher can 
+be bound to the CHC hash at a time.  There are additional requirements for the system to work.
+
+\begin{enumerate}
+   \item The cipher must have a block size greater than 64--bits.  
+   \item The cipher must allow an input key the size of the block size.
+\end{enumerate}
+
+Example of using CHC with the AES block cipher.
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int err; 
+
+   /* register cipher and hash */
+   if (register_cipher(&aes_enc_desc) == -1) {
+      printf("Could not register cipher\n");
+      return EXIT_FAILURE;
+   }
+   if (register_hash(&chc_desc) == -1) {
+      printf("Could not register hash\n");
+      return EXIT_FAILURE;
+   }
+
+   /* start chc with AES */
+   if ((err = chc_register(find_cipher("aes"))) != CRYPT_OK) {
+      printf("Error binding AES to CHC: %s\n", 
+             error_to_string(err));
+   }
+
+   /* now you can use chc_hash in any LTC function 
+    * [aside from pkcs...] */
+}
+\end{verbatim}
+
+
+\mysection{Notice}
+It is highly recommended that you \textbf{not} use the MD4 or MD5 hashes for the purposes of digital signatures or authentication codes.  
+These hashes are provided for completeness and they still can be used for the purposes of password hashing or one-way accumulators
+(e.g. Yarrow).
+
+The other hashes such as the SHA-1, SHA-2 (that includes SHA-512, SHA-384 and SHA-256) and TIGER-192 are still considered secure
+for all purposes you would normally use a hash for.
+
+\chapter{Message Authentication Codes}
+\mysection{HMAC Protocol}
+Thanks to Dobes Vandermeer, the library now includes support for hash based message authentication codes, or HMAC for short.  An HMAC
+of a message is a keyed authentication code that only the owner of a private symmetric key will be able to verify.  The purpose is
+to allow an owner of a private symmetric key to produce an HMAC on a message then later verify if it is correct.  Any impostor or
+eavesdropper will not be able to verify the authenticity of a message.  
+
+The HMAC support works much like the normal hash functions except that the initialization routine requires you to pass a key 
+and its length.  The key is much like a key you would pass to a cipher.  That is, it is simply an array of octets stored in
+unsigned characters.  The initialization routine is:
+\index{hmac\_init()}
+\begin{verbatim}
+int hmac_init(         hmac_state *hmac, 
+                              int  hash, 
+              const unsigned char *key, 
+                    unsigned long  keylen);
+\end{verbatim}
+The \textit{hmac} parameter is the state for the HMAC code.  The \textit{hash} parameter is the index into the descriptor table of the hash you want
+to use to authenticate the message.  The \textit{key} parameter is the pointer to the array of chars that make up the key.  The \textit{keylen} parameter is the
+length (in octets) of the key you want to use to authenticate the message.  To send octets of a message through the HMAC system you must use the following function:
+\index{hmac\_process()}
+\begin{verbatim}
+int hmac_process(         hmac_state *hmac, 
+                 const unsigned char *in, 
+                       unsigned long  inlen);
+\end{verbatim}
+\textit{hmac} is the HMAC state you are working with. \textit{buf} is the array of octets to send into the HMAC process.  \textit{len} is the
+number of octets to process.  Like the hash process routines you can send the data in arbitrarily sized chunks. When you 
+are finished with the HMAC process you must call the following function to get the HMAC code:
+\index{hmac\_done()}
+\begin{verbatim}
+int hmac_done(   hmac_state *hmac, 
+              unsigned char *out, 
+              unsigned long *outlen);
+\end{verbatim}
+The \textit{hmac} parameter is the HMAC state you are working with.  The \textit{out} parameter is the array of octets where the HMAC code should be stored.  
+You must set \textit{outlen} to the size of the destination buffer before calling this function.  It is updated with the length of the HMAC code
+produced (depending on which hash was picked).  If \textit{outlen} is less than the size of the message digest (and ultimately
+the HMAC code) then the HMAC code is truncated as per FIPS-198 specifications (e.g. take the first \textit{outlen} bytes).
+
+There are two utility functions provided to make using HMACs easier to do.  They accept the key and information about the
+message (file pointer, address in memory), and produce the HMAC result in one shot.  These are useful if you want to avoid
+calling the three step process yourself.
+
+\index{hmac\_memory()}
+\begin{verbatim}
+int hmac_memory(
+                   int  hash, 
+   const unsigned char *key, unsigned long  keylen,
+   const unsigned char *in,  unsigned long  inlen, 
+         unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will produce an HMAC code for the array of octets in \textit{in} of length \textit{inlen}.  The index into the hash descriptor 
+table must be provided in \textit{hash}.  It uses the key from \textit{key} with a key length of \textit{keylen}.  
+The result is stored in the array of octets \textit{out} and the length in \textit{outlen}.  The value of \textit{outlen} must be set
+to the size of the destination buffer before calling this function.  Similarly for files there is the  following function:
+\index{hmac\_file()}
+\begin{verbatim}
+int hmac_file(
+                   int  hash, 
+            const char *fname, 
+   const unsigned char *key, unsigned long  keylen, 
+         unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+\textit{hash} is the index into the hash descriptor table of the hash you want to use.  \textit{fname} is the filename to process.  
+\textit{key} is the array of octets to use as the key of length \textit{keylen}.  \textit{out} is the array of octets where the 
+result should be stored.
+
+To test if the HMAC code is working there is the following function:
+\index{hmac\_test()}
+\begin{verbatim}
+int hmac_test(void);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if the code passes otherwise it returns an error code.  Some example code for using the 
+HMAC system is given below.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int idx, err;
+   hmac_state hmac;
+   unsigned char key[16], dst[MAXBLOCKSIZE];
+   unsigned long dstlen;
+
+   /* register SHA-1 */
+   if (register_hash(&sha1_desc) == -1) {
+      printf("Error registering SHA1\n");
+      return -1;
+   }
+
+   /* get index of SHA1 in hash descriptor table */
+   idx = find_hash("sha1");
+
+   /* we would make up our symmetric key in "key[]" here */
+
+   /* start the HMAC */
+   if ((err = hmac_init(&hmac, idx, key, 16)) != CRYPT_OK) {
+      printf("Error setting up hmac: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* process a few octets */
+   if((err = hmac_process(&hmac, "hello", 5) != CRYPT_OK) {
+      printf("Error processing hmac: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* get result (presumably to use it somehow...) */
+   dstlen = sizeof(dst);
+   if ((err = hmac_done(&hmac, dst, &dstlen)) != CRYPT_OK) {
+      printf("Error finishing hmac: %s\n", error_to_string(err));
+      return -1;
+   }
+   printf("The hmac is %lu bytes long\n", dstlen);
+  
+   /* return */
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+\mysection{OMAC Support}
+\index{OMAC} \index{CMAC}
+OMAC\footnote{\url{http://crypt.cis.ibaraki.ac.jp/omac/omac.html}}, which stands for \textit{One-Key CBC MAC} is an 
+algorithm which produces a Message Authentication Code (MAC) using only a block cipher such as AES.  Note:  OMAC has been standardized as
+CMAC within NIST, for the purposes of this library OMAC and CMAC are synonymous.  From an API standpoint, the OMAC routines work much like the 
+HMAC routines.  Instead, in this case a cipher is used instead of a hash.  
+
+To start an OMAC state you call
+\index{omac\_init()}
+\begin{verbatim}
+int omac_init(         omac_state *omac, 
+                              int  cipher, 
+              const unsigned char *key, 
+                    unsigned long  keylen);
+\end{verbatim}
+The \textit{omac} parameter is the state for the OMAC algorithm.  The \textit{cipher} parameter is the index into the cipher\_descriptor table
+of the cipher\footnote{The cipher must have a 64 or 128 bit block size.  Such as CAST5, Blowfish, DES, AES, Twofish, etc.} you
+wish to use.  The \textit{key} and \textit{keylen} parameters are the keys used to authenticate the data.
+
+To send data through the algorithm call
+\index{omac\_process()}
+\begin{verbatim}
+int omac_process(         omac_state *state, 
+                 const unsigned char *in, 
+                       unsigned long  inlen);
+\end{verbatim}
+This will send \textit{inlen} bytes from \textit{in} through the active OMAC state \textit{state}.  Returns \textbf{CRYPT\_OK} if the 
+function succeeds.  The function is not sensitive to the granularity of the data.  For example,
+
+\begin{verbatim}
+omac_process(&mystate, "hello",  5);
+omac_process(&mystate, " world", 6);
+\end{verbatim}
+
+Would produce the same result as,
+
+\begin{verbatim}
+omac_process(&mystate, "hello world",  11);
+\end{verbatim}
+
+When you are done processing the message you can call the following to compute the message tag.
+
+\index{omac\_done()}
+\begin{verbatim}
+int omac_done(   omac_state *state, 
+              unsigned char *out, 
+              unsigned long *outlen);
+\end{verbatim}
+Which will terminate the OMAC and output the \textit{tag} (MAC) to \textit{out}.  Note that unlike the HMAC and other code 
+\textit{outlen} can be smaller than the default MAC size (for instance AES would make a 16-byte tag).  Part of the OMAC 
+specification states that the output may be truncated.  So if you pass in $outlen = 5$ and use AES as your cipher than
+the output MAC code will only be five bytes long.  If \textit{outlen} is larger than the default size it is set to the default
+size to show how many bytes were actually used.
+
+Similar to the HMAC code the file and memory functions are also provided.  To OMAC a buffer of memory in one shot use the 
+following function.
+
+\index{omac\_memory()}
+\begin{verbatim}
+int omac_memory(                
+                    int  cipher, 
+    const unsigned char *key, unsigned long keylen,
+    const unsigned char *in,  unsigned long inlen,
+          unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will compute the OMAC of \textit{inlen} bytes of \textit{in} using the key \textit{key} of length \textit{keylen} bytes and the cipher
+specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with the same
+rules as omac\_done.
+
+To OMAC a file use
+\index{omac\_file()}
+\begin{verbatim}
+int omac_file(
+                    int  cipher, 
+    const unsigned char *key,      unsigned long keylen,
+             const char *filename, 
+          unsigned char *out,      unsigned long *outlen);
+\end{verbatim}
+
+Which will OMAC the entire contents of the file specified by \textit{filename} using the key \textit{key} of length \textit{keylen} bytes
+and the cipher specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with 
+the same rules as omac\_done.
+
+To test if the OMAC code is working there is the following function:
+\index{omac\_test()}
+\begin{verbatim}
+int omac_test(void);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if the code passes otherwise it returns an error code.  Some example code for using the 
+OMAC system is given below.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int idx, err;
+   omac_state omac;
+   unsigned char key[16], dst[MAXBLOCKSIZE];
+   unsigned long dstlen;
+
+   /* register Rijndael */
+   if (register_cipher(&rijndael_desc) == -1) {
+      printf("Error registering Rijndael\n");
+      return -1;
+   }
+
+   /* get index of Rijndael in cipher descriptor table */
+   idx = find_cipher("rijndael");
+
+   /* we would make up our symmetric key in "key[]" here */
+
+   /* start the OMAC */
+   if ((err = omac_init(&omac, idx, key, 16)) != CRYPT_OK) {
+      printf("Error setting up omac: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* process a few octets */
+   if((err = omac_process(&omac, "hello", 5) != CRYPT_OK) {
+      printf("Error processing omac: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* get result (presumably to use it somehow...) */
+   dstlen = sizeof(dst);
+   if ((err = omac_done(&omac, dst, &dstlen)) != CRYPT_OK) {
+      printf("Error finishing omac: %s\n", error_to_string(err));
+      return -1;
+   }
+   printf("The omac is %lu bytes long\n", dstlen);
+  
+   /* return */
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+\mysection{PMAC Support}
+The PMAC\footnote{J.Black, P.Rogaway, \textit{A Block--Cipher Mode of Operation for Parallelizable Message Authentication}} 
+protocol is another MAC algorithm that relies solely on a symmetric-key block cipher.  It uses essentially the same
+API as the provided OMAC code.  
+
+A PMAC state is initialized with the following.
+
+\index{pmac\_init()}
+\begin{verbatim}
+int pmac_init(         pmac_state *pmac, 
+                              int  cipher, 
+              const unsigned char *key, 
+                    unsigned long  keylen);
+\end{verbatim}
+Which initializes the \textit{pmac} state with the given \textit{cipher} and \textit{key} of length \textit{keylen} bytes.  The chosen cipher
+must have a 64 or 128 bit block size (e.x. AES).
+
+To MAC data simply send it through the process function.
+
+\index{pmac\_process()}
+\begin{verbatim}
+int pmac_process(         pmac_state *state, 
+                 const unsigned char *in, 
+                       unsigned long  inlen);
+\end{verbatim}
+This will process \textit{inlen} bytes of \textit{in} in the given \textit{state}.  The function is not sensitive to the granularity of the
+data.  For example,
+
+\begin{verbatim}
+pmac_process(&mystate, "hello",  5);
+pmac_process(&mystate, " world", 6);
+\end{verbatim}
+
+Would produce the same result as,
+
+\begin{verbatim}
+pmac_process(&mystate, "hello world",  11);
+\end{verbatim}
+
+When a complete message has been processed the following function can be called to compute the message tag.
+
+\index{pmac\_done()}
+\begin{verbatim}
+int pmac_done(   pmac_state *state, 
+              unsigned char *out, 
+              unsigned long *outlen);
+\end{verbatim}
+This will store up to \textit{outlen} bytes of the tag for the given \textit{state} into \textit{out}.  Note that if \textit{outlen} is larger
+than the size of the tag it is set to the amount of bytes stored in \textit{out}.
+
+Similar to the OMAC code the file and memory functions are also provided.  To PMAC a buffer of memory in one shot use the 
+following function.
+
+\index{pmac\_memory()}
+\begin{verbatim}
+int pmac_memory(
+                    int  cipher, 
+    const unsigned char *key, unsigned long  keylen,
+    const unsigned char *in,  unsigned long  inlen,
+          unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will compute the PMAC of \textit{msglen} bytes of \textit{msg} using the key \textit{key} of length \textit{keylen} bytes, and the cipher
+specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with the same
+rules as pmac\_done().
+
+To PMAC a file use
+\index{pmac\_file()}
+\begin{verbatim}
+int pmac_file(
+                    int  cipher, 
+    const unsigned char *key,      unsigned long keylen,
+             const char *filename, 
+          unsigned char *out,      unsigned long *outlen);
+\end{verbatim}
+
+Which will PMAC the entire contents of the file specified by \textit{filename} using the key \textit{key} of length \textit{keylen} bytes, 
+and the cipher specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with 
+the same rules as pmac\_done().
+
+To test if the PMAC code is working there is the following function:
+\index{pmac\_test()}
+\begin{verbatim}
+int pmac_test(void);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if the code passes otherwise it returns an error code.
+
+\mysection{Pelican MAC}
+Pelican MAC is a new (experimental) MAC by the AES team that uses four rounds of AES as a \textit{mixing function}.  It achieves a very high 
+rate of processing and is potentially very secure.  It requires AES to be enabled to function.  You do not have to register\_cipher() AES first though
+as it calls AES directly.
+
+\index{pelican\_init()}
+\begin{verbatim}
+int pelican_init(      pelican_state *pelmac, 
+                 const unsigned char *key, 
+                       unsigned long  keylen);
+\end{verbatim}
+This will initialize the Pelican state with the given AES key.  Once this has been done you can begin processing data.
+
+\index{pelican\_process()}
+\begin{verbatim}
+int pelican_process(      pelican_state *pelmac, 
+                    const unsigned char *in, 
+                          unsigned long  inlen);
+\end{verbatim}
+This will process \textit{inlen} bytes of \textit{in} through the Pelican MAC.  It's best that you pass in multiples of 16 bytes as it makes the
+routine more efficient but you may pass in any length of text.  You can call this function as many times as required to process
+an entire message.
+
+\index{pelican\_done()}
+\begin{verbatim}
+int pelican_done(pelican_state *pelmac, unsigned char *out);
+\end{verbatim}
+This terminates a Pelican MAC and writes the 16--octet tag to \textit{out}.
+
+\subsection{Example}

+\mysection{XCBC-MAC}
+As of LibTomCrypt v1.15, XCBC-MAC (RFC 3566) has been provided to support TLS encryption suites.  Like OMAC, it computes a message authentication code
+by using a cipher in CBC mode.  It also uses a single key which it expands into the requisite three keys for the MAC function.  A XCBC--MAC state is
+initialized with the following function:
+
+\index{xcbc\_init()}
+\begin{verbatim}
+int xcbc_init(         xcbc_state *xcbc, 
+                              int  cipher, 
+              const unsigned char *key, 
+                    unsigned long  keylen);
+\end{verbatim}
+
+This will initialize the XCBC--MAC state \textit{xcbc}, with the key specified in \textit{key} of length \textit{keylen} octets.  The cipher indicated
+by the \textit{cipher} index can be either a 64 or 128--bit block cipher.  This will return \textbf{CRYPT\_OK} on success.
+
+To process data through XCBC--MAC use the following function:
+
+\index{xcbc\_process()}
+\begin{verbatim}
+int xcbc_process(         xcbc_state *state, 
+                 const unsigned char *in, 
+                       unsigned long  inlen);
+\end{verbatim}
+
+This will add the message octets pointed to by \textit{in} of length \textit{inlen} to the XCBC--MAC state pointed to by \textit{state}.  Like the other MAC functions,
+the granularity of the input is not important but the order is.  This will return \textbf{CRYPT\_OK} on success.
+
+To compute the MAC tag value use the following function:
+
+\index{xcbc\_done()}
+\begin{verbatim}
+int xcbc_done(   xcbc_state *state, 
+              unsigned char *out, 
+              unsigned long *outlen);
+\end{verbatim}
+
+This will retrieve the XCBC--MAC tag from the state pointed to by \textit{state}, and store it in the array pointed to by \textit{out}.  The \textit{outlen} parameter
+specifies the maximum size of the destination buffer, and is updated to hold the final size of the tag when the function returns.  This will return \textbf{CRYPT\_OK} on success.
+
+Helper functions are provided to make parsing memory buffers and files easier.  The following functions are provided:
+
+\index{xcbc\_memory()}
+\begin{verbatim}
+int xcbc_memory(
+                    int  cipher, 
+    const unsigned char *key, unsigned long  keylen,
+    const unsigned char *in,  unsigned long  inlen,
+          unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will compute the XCBC--MAC of \textit{msglen} bytes of \textit{msg}, using the key \textit{key} of length \textit{keylen} bytes, and the cipher
+specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with the same rules as xcbc\_done().
+
+To xcbc a file use
+\index{xcbc\_file()}
+\begin{verbatim}
+int xcbc_file(
+                    int  cipher, 
+    const unsigned char *key,      unsigned long keylen,
+             const char *filename, 
+          unsigned char *out,      unsigned long *outlen);
+\end{verbatim}
+
+Which will XCBC--MAC the entire contents of the file specified by \textit{filename} using the key \textit{key} of length \textit{keylen} bytes, and the cipher 
+specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with the same rules as xcbc\_done().
+
+
+To test XCBC--MAC for RFC 3566 compliance use the following function:
+
+\index{xcbc\_test()}
+\begin{verbatim}
+int xcbc_test(void);
+\end{verbatim}
+
+This will return \textbf{CRYPT\_OK} on success.  This requires the AES or Rijndael descriptor be previously registered, otherwise, it will return 
+\textbf{CRYPT\_NOP}. 
+
+\mysection{F9--MAC}
+The F9--MAC is yet another CBC--MAC variant proposed for the 3GPP standard.  Originally specified to be used with the KASUMI block cipher, it can also be used
+with other ciphers.  For LibTomCrypt, the F9--MAC code can use any cipher.  
+
+\subsection{Usage Notice}
+F9--MAC differs slightly from the other MAC functions in that it requires the caller to perform the final message padding.  The padding quite simply is a direction
+bit followed by a 1 bit and enough zeros to make the message a multiple of the cipher block size.  If the message is byte aligned, the padding takes on the form of 
+a single 0x40 or 0xC0 byte followed by enough 0x00 bytes to make the message proper multiple.  
+
+If the user simply wants a MAC function (hint: use OMAC) padding with a single 0x40 byte should be sufficient for security purposes and still be reasonably compatible
+with F9--MAC.
+
+\subsection{F9--MAC Functions}
+A F9--MAC state is initialized with the following function:
+\index{f9\_init()}
+\begin{verbatim}
+int f9_init(           f9_state *f9, 
+                            int  cipher, 
+            const unsigned char *key, 
+                  unsigned long  keylen);
+\end{verbatim}
+
+This will initialize the F9--MAC state \textit{f9}, with the key specified in \textit{key} of length \textit{keylen} octets.  The cipher indicated
+by the \textit{cipher} index can be either a 64 or 128--bit block cipher.  This will return \textbf{CRYPT\_OK} on success.
+
+To process data through F9--MAC use the following function:
+\index{f9\_process()}
+\begin{verbatim}
+int f9_process(           f9_state *state, 
+               const unsigned char *in, 
+                     unsigned long  inlen);
+\end{verbatim}
+
+This will add the message octets pointed to by \textit{in} of length \textit{inlen} to the F9--MAC state pointed to by \textit{state}.  Like the other MAC functions,
+the granularity of the input is not important but the order is.  This will return \textbf{CRYPT\_OK} on success.
+
+To compute the MAC tag value use the following function:
+
+\index{f9\_done()}
+\begin{verbatim}
+int f9_done(     f9_state *state, 
+            unsigned char *out, 
+            unsigned long *outlen);
+\end{verbatim}
+
+This will retrieve the F9--MAC tag from the state pointed to by \textit{state}, and store it in the array pointed to by \textit{out}.  The \textit{outlen} parameter
+specifies the maximum size of the destination buffer, and is updated to hold the final size of the tag when the function returns.  This will return 
+\textbf{CRYPT\_OK} on success.
+
+Helper functions are provided to make parsing memory buffers and files easier.  The following functions are provided:
+
+\index{f9\_memory()}
+\begin{verbatim}
+int f9_memory(
+                    int  cipher, 
+    const unsigned char *key, unsigned long  keylen,
+    const unsigned char *in,  unsigned long  inlen,
+          unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will compute the F9--MAC of \textit{msglen} bytes of \textit{msg}, using the key \textit{key} of length \textit{keylen} bytes, and the cipher
+specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with the same rules as f9\_done().
+
+To F9--MAC a file use
+\index{f9\_file()}
+\begin{verbatim}
+int f9_file(
+                    int  cipher, 
+    const unsigned char *key,      unsigned long keylen,
+             const char *filename, 
+          unsigned char *out,      unsigned long *outlen);
+\end{verbatim}
+
+Which will F9--MAC the entire contents of the file specified by \textit{filename} using the key \textit{key} of length \textit{keylen} bytes, and the cipher 
+specified by the \textit{cipher}'th entry in the cipher\_descriptor table.  It will store the MAC in \textit{out} with the same rules as f9\_done().
+
+
+To test f9--MAC for RFC 3566 compliance use the following function:
+
+\index{f9\_test()}
+\begin{verbatim}
+int f9_test(void);
+\end{verbatim}
+
+This will return \textbf{CRYPT\_OK} on success.  This requires the AES or Rijndael descriptor be previously registered, otherwise, it will return 
+\textbf{CRYPT\_NOP}. 
+
+\chapter{Pseudo-Random Number Generators}
+\mysection{Core Functions}
+The library provides an array of core functions for Pseudo-Random Number Generators (PRNGs) as well.  A cryptographic PRNG is
+used to expand a shorter bit string into a longer bit string.  PRNGs are used wherever random data is required such as Public Key (PK)
+key generation.  There is a universal structure called \textit{prng\_state}.  To initialize a PRNG call:
+\index{PRNG start}
+\begin{verbatim}
+int XXX_start(prng_state *prng);
+\end{verbatim}
+
+This will setup the PRNG for future use and not seed it.  In order for the PRNG to be cryptographically useful you must give it 
+entropy.  Ideally you'd have some OS level source to tap like in UNIX.  To add entropy to the PRNG call:
+\index{PRNG add\_entropy}
+\begin{verbatim}
+int XXX_add_entropy(const unsigned char *in, 
+                          unsigned long  inlen, 
+                             prng_state *prng);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if the entropy was accepted.  Once you think you have enough entropy you call another
+function to put the entropy into action.
+\index{PRNG ready}
+\begin{verbatim}
+int XXX_ready(prng_state *prng);
+\end{verbatim}
+
+Which returns {\bf CRYPT\_OK} if it is ready.  Finally to actually read bytes call:
+\index{PRNG read}
+\begin{verbatim}
+unsigned long XXX_read(unsigned char *out, 
+                       unsigned long  outlen,
+                          prng_state *prng);
+\end{verbatim}
+
+Which returns the number of bytes read from the PRNG.  When you are finished with a PRNG state you call
+the following.
+
+\index{PRNG done}
+\begin{verbatim}
+void XXX_done(prng_state *prng);
+\end{verbatim}
+
+This will terminate a PRNG state and free any memory (if any) allocated.  To export a PRNG state
+so that you can later resume the PRNG call the following.
+
+\index{PRNG export}
+\begin{verbatim}
+int XXX_export(unsigned char *out, 
+               unsigned long *outlen, 
+                  prng_state *prng);
+\end{verbatim}
+
+This will write a \textit{PRNG state} to the buffer \textit{out} of length \textit{outlen} bytes.  The idea of 
+the export is meant to be used as a \textit{seed file}.  That is, when the program starts up there will not likely
+be that much entropy available.   To import a state to seed a PRNG call the following function.
+
+\index{PRNG import}
+\begin{verbatim}
+int XXX_import(const unsigned char *in, 
+                     unsigned long  inlen, 
+                        prng_state *prng);
+\end{verbatim}
+
+This will call the start and add\_entropy functions of the given PRNG.  It will use the state in
+\textit{in} of length \textit{inlen} as the initial seed.  You must pass the same seed length as was exported
+by the corresponding export function.
+
+Note that importing a state will not \textit{resume} the PRNG from where it left off.  That is, if you export
+a state, emit (say) 8 bytes and then import the previously exported state the next 8 bytes will not 
+specifically equal the 8 bytes you generated previously.
+
+When a program is first executed the normal course of operation is:
+
+\begin{enumerate}
+   \item Gather entropy from your sources for a given period of time or number of events.
+   \item Start, use your entropy via add\_entropy and ready the PRNG yourself.
+\end{enumerate}
+
+When your program is finished you simply call the export function and save the state to a medium (disk,
+flash memory, etc).  The next time your application starts up you can detect the state, feed it to the 
+import function and go on your way.  It is ideal that (as soon as possible) after start up you export a
+fresh state.  This helps in the case that the program aborts or the machine is powered down without
+being given a chance to exit properly.  
+
+Note that even if you have a state to import it is important to add new entropy to the state.  However,
+there is less pressure to do so.  
+
+To test a PRNG for operational conformity call the following functions.
+
+\index{PRNG test}
+\begin{verbatim}
+int XXX_test(void);
+\end{verbatim}
+
+This will return \textbf{CRYPT\_OK} if PRNG is operating properly.
+
+\subsection{Remarks}
+
+It is possible to be adding entropy and reading from a PRNG at the same time.  For example, if you first seed the PRNG
+and call ready() you can now read from it.  You can also keep adding new entropy to it.  The new entropy will not be used
+in the PRNG until ready() is called again.  This allows the PRNG to be used and re-seeded at the same time.  No real error 
+checking is guaranteed to see if the entropy is sufficient, or if the PRNG is even in a ready state before reading.
+
+\subsection{Example}
+Below is a simple snippet to read 10 bytes from Yarrow.  It is important to note that this snippet is {\bf NOT} secure since 
+the entropy added is not random.
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   prng_state prng;
+   unsigned char buf[10];
+   int err;
+   
+   /* start it */
+   if ((err = yarrow_start(&prng)) != CRYPT_OK) {
+      printf("Start error: %s\n", error_to_string(err));
+   }
+   /* add entropy */
+   if ((err = yarrow_add_entropy("hello world", 11, &prng)) 
+       != CRYPT_OK) {
+      printf("Add_entropy error: %s\n", error_to_string(err));
+   }
+   /* ready and read */
+   if ((err = yarrow_ready(&prng)) != CRYPT_OK) {
+      printf("Ready error: %s\n", error_to_string(err));
+   }
+   printf("Read %lu bytes from yarrow\n", 
+          yarrow_read(buf, sizeof(buf), &prng));
+   return 0;
+}
+\end{verbatim}
+
+\mysection{PRNG Descriptors}
+\index{PRNG Descriptor}
+PRNGs have descriptors that allow plugin driven functions to be created using PRNGs. The plugin descriptors are stored in the structure \textit{prng\_descriptor}.  The 
+format of an element is:
+\begin{verbatim}
+struct _prng_descriptor {
+    char *name;
+    int  export_size;    /* size in bytes of exported state */
+
+    int (*start)      (prng_state *);
+
+    int (*add_entropy)(const unsigned char *, unsigned long, 
+                       prng_state *);
+
+    int (*ready)      (prng_state *);
+
+    unsigned long (*read)(unsigned char *, unsigned long len, 
+                          prng_state *);
+
+    void (*done)(prng_state *);
+
+    int (*export)(unsigned char *, unsigned long *, prng_state *);
+
+    int (*import)(const unsigned char *, unsigned long, prng_state *);
+
+    int (*test)(void);
+};
+\end{verbatim}
+
+To find a PRNG in the descriptor table the following function can be used:
+\index{find\_prng()}
+\begin{verbatim}
+int find_prng(const char *name);
+\end{verbatim}
+This will search the PRNG descriptor table for the PRNG named \textit{name}.  It will return -1 if the PRNG is not found, otherwise, it returns
+the index into the descriptor table.
+
+Just like the ciphers and hashes, you must register your prng before you can use it.  The two functions provided work exactly as those for the cipher registry functions.  
+They are the following:
+\index{register\_prng()} \index{unregister\_prng()}
+\begin{verbatim}
+int register_prng(const struct _prng_descriptor *prng);
+int unregister_prng(const struct _prng_descriptor *prng);
+\end{verbatim}
+
+The register function will register the PRNG, and return the index into the table where it was placed (or -1 for error).  It will avoid registering the same
+descriptor twice, and will return the index of the current placement in the table if the caller attempts to register it more than once.  The unregister function
+will return \textbf{CRYPT\_OK} if the PRNG was found and removed.  Otherwise, it returns \textbf{CRYPT\_ERROR}.
+

+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{List of Provided PRNGs}
+\end{figure}
+
+\subsubsection{Yarrow}
+Yarrow is fast PRNG meant to collect an unspecified amount of entropy from sources 
+(keyboard, mouse, interrupts, etc), and produce an unbounded string of random bytes.  
+
+\textit{Note:} This PRNG is still secure for most tasks but is no longer recommended.  Users
+should use Fortuna instead.
+
+\subsubsection{Fortuna}
+
+Fortuna is a fast attack tolerant and more thoroughly designed PRNG suitable for long term
+usage.  It is faster than the default implementation of Yarrow\footnote{Yarrow has been implemented
+to work with most cipher and hash combos based on which you have chosen to build into the library.} while
+providing more security.  
+
+Fortuna is slightly less flexible than Yarrow in the sense that it only works with the AES block cipher 
+and SHA--256 hash function.  Technically, Fortuna will work with any block cipher that accepts a 256--bit
+key, and any hash that produces at least a 256--bit output.  However, to make the implementation simpler
+it has been fixed to those choices.
+
+Fortuna is more secure than Yarrow in the sense that attackers who learn parts of the entropy being 
+added to the PRNG learn far less about the state than that of Yarrow.  Without getting into to many
+details Fortuna has the ability to recover from state determination attacks where the attacker starts
+to learn information from the PRNGs output about the internal state.  Yarrow on the other hand, cannot 
+recover from that problem until new entropy is added to the pool and put to use through the ready() function.
+
+\subsubsection{RC4}
+
+RC4 is an old stream cipher that can also double duty as a PRNG in a pinch.  You key RC4 by
+calling add\_entropy(), and setup the key by calling ready().  You can only add up to 256 bytes via
+add\_entropy().  
+
+When you read from RC4, the output is XOR'ed against your buffer you provide.  In this manner, you can use rc4\_read() 
+as an encrypt (and decrypt) function.  
+
+You really should not use RC4.  This is not because RC4 is weak, (though biases are known to exist) but simply due to 
+the fact that faster alternatives exist.
+
+\subsubsection{SOBER-128}
+
+SOBER--128 is a stream cipher designed by the QUALCOMM Australia team.  Like RC4, you key it by 
+calling add\_entropy().  There is no need to call ready() for this PRNG as it does not do anything.  
+
+Note: this cipher has several oddities about how it operates.  The first call to add\_entropy() sets the cipher's key.  
+Every other time call to the add\_entropy() function sets the cipher's IV variable.  The IV mechanism allows you to 
+encrypt several messages with the same key, and not re--use the same key material.
+
+Unlike Yarrow and Fortuna, all of the entropy (and hence security) of this algorithm rests in the data
+you pass it on the \textbf{first} call to add\_entropy().  All buffers sent to add\_entropy() must have a length
+that is a multiple of four bytes.
+
+Like RC4, the output of SOBER--128 is XOR'ed against the buffer you provide it.  In this manner, you can use
+sober128\_read() as an encrypt (and decrypt) function.
+
+Since SOBER-128 has a fixed keying scheme, and is very fast (faster than RC4) the ideal usage of SOBER-128 is to 
+key it from the output of Fortuna (or Yarrow), and use it to encrypt messages.  It is also ideal for
+simulations which need a high quality (and fast) stream of bytes.  
+
+\subsubsection{Example Usage}
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   prng_state prng;
+   unsigned char buf[32];
+   int err;
+
+   if ((err = rc4_start(&prng)) != CRYPT_OK) {
+      printf("RC4 init error: %s\n", error_to_string(err));
+      exit(-1);
+   }
+
+   /* use "key" as the key */
+   if ((err = rc4_add_entropy("key", 3, &prng)) != CRYPT_OK) {
+      printf("RC4 add entropy error: %s\n", error_to_string(err));
+      exit(-1);
+   }
+
+   /* setup RC4 for use */
+   if ((err = rc4_ready(&prng)) != CRYPT_OK) {
+      printf("RC4 ready error: %s\n", error_to_string(err));
+      exit(-1);
+   }
+
+   /* encrypt buffer */
+   strcpy(buf,"hello world");
+   if (rc4_read(buf, 11, &prng) != 11) {
+      printf("RC4 read error\n");
+      exit(-1);
+   }
+   return 0;
+}   
+\end{verbatim}
+\end{small}
+To decrypt you have to do the exact same steps.  
+
+\mysection{The Secure RNG}
+\index{Secure RNG}
+An RNG is related to a PRNG in many ways, except that it does not expand a smaller seed to get the data.  They generate their random bits
+by performing some computation on fresh input bits.  Possibly the hardest thing to get correctly in a cryptosystem is the 
+PRNG.  Computers are deterministic that try hard not to stray from pre--determined paths.  This makes gathering entropy needed to seed a PRNG 
+a hard task.  
+
+There is one small function that may help on certain platforms:
+\index{rng\_get\_bytes()}
+\begin{verbatim}
+unsigned long rng_get_bytes(
+    unsigned char *buf, 
+    unsigned long  len, 
+    void         (*callback)(void));
+\end{verbatim}
+
+Which will try one of three methods of getting random data.  The first is to open the popular \textit{/dev/random} device which 
+on most *NIX platforms provides cryptographic random bits\footnote{This device is available in Windows through the Cygwin compiler suite.  It emulates \textit{/dev/random} via the Microsoft CSP.}.  
+The second method is to try the Microsoft Cryptographic Service Provider, and read the RNG.  The third method is an ANSI C 
+clock drift method that is also somewhat popular but gives bits of lower entropy.  The \textit{callback} parameter is a pointer to a function that returns void.  It is 
+used when the slower ANSI C RNG must be used so the calling application can still work.  This is useful since the ANSI C RNG has a throughput of roughly three 
+bytes a second.  The callback pointer may be set to {\bf NULL} to avoid using it if you do not want to.  The function returns the number of bytes actually read from 
+any RNG source.  There is a function to help setup a PRNG as well:
+\index{rng\_make\_prng()}
+\begin{verbatim}
+int rng_make_prng(       int  bits, 
+                         int  wprng, 
+                  prng_state *prng, 
+                       void (*callback)(void));
+\end{verbatim}
+This will try to initialize the prng with a state of at least \textit{bits} of entropy.  The \textit{callback} parameter works much like
+the callback in \textit{rng\_get\_bytes()}.  It is highly recommended that you use this function to setup your PRNGs unless you have a
+platform where the RNG does not work well.  Example usage of this function is given below:
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   ecc_key mykey;
+   prng_state prng;
+   int err;
+
+   /* register yarrow */
+   if (register_prng(&yarrow_desc) == -1) {
+      printf("Error registering Yarrow\n");
+      return -1;
+   }
+
+   /* setup the PRNG */
+   if ((err = rng_make_prng(128, find_prng("yarrow"), &prng, NULL)) 
+       != CRYPT_OK) {
+      printf("Error setting up PRNG, %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* make a 192-bit ECC key */
+   if ((err = ecc_make_key(&prng, find_prng("yarrow"), 24, &mykey)) 
+       != CRYPT_OK) {
+      printf("Error making key: %s\n", error_to_string(err));
+      return -1;
+   }
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+\subsection{The Secure PRNG Interface}
+It is possible to access the secure RNG through the PRNG interface, and in turn use it within dependent functions such
+as the PK API.  This simplifies the cryptosystem on platforms where the secure RNG is fast.  The secure PRNG never 
+requires to be started, that is you need not call the start, add\_entropy, or ready functions.  For example, consider
+the previous example using this PRNG.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   ecc_key mykey;
+   int err;
+
+   /* register SPRNG */
+   if (register_prng(&sprng_desc) == -1) {
+      printf("Error registering SPRNG\n");
+      return -1;
+   }
+
+   /* make a 192-bit ECC key */
+   if ((err = ecc_make_key(NULL, find_prng("sprng"), 24, &mykey)) 
+       != CRYPT_OK) {
+      printf("Error making key: %s\n", error_to_string(err));
+      return -1;
+   }
+   return 0;

+\chapter{RSA Public Key Cryptography}
+
+\mysection{Introduction}
+RSA wrote the PKCS \#1 specifications which detail RSA Public Key Cryptography.  In the specifications are
+padding algorithms for encryption and signatures.  The standard includes the \textit{v1.5} and \textit{v2.1} algorithms.
+To simplify matters a little the v2.1 encryption and signature padding algorithms are called OAEP and PSS respectively.  
+
+\mysection{PKCS \#1 Padding}
+PKCS \#1 v1.5 padding is so simple that both signature and encryption padding are performed by the same function.  Note: the
+signature padding does \textbf{not} include the ASN.1 padding required.  That is performed by the rsa\_sign\_hash\_ex() function
+documented later on in this chapter.  
+
+\subsection{PKCS \#1 v1.5 Encoding}
+The following function performs PKCS \#1 v1.5 padding:
+\index{pkcs\_1\_v1\_5\_encode()}
+\begin{verbatim}
+int pkcs_1_v1_5_encode(
+    const unsigned char *msg, 
+          unsigned long  msglen,
+                    int  block_type,
+          unsigned long  modulus_bitlen,
+             prng_state *prng, 
+                    int  prng_idx,
+          unsigned char *out, 
+          unsigned long *outlen);
+\end{verbatim}
+
+This will encode the message pointed to by \textit{msg} of length \textit{msglen} octets.  The \textit{block\_type} parameter must be set to
+\textbf{LTC\_PKCS\_1\_EME} to perform encryption padding.  It must be set to \textbf{LTC\_PKCS\_1\_EMSA} to perform signature padding.  The \textit{modulus\_bitlen} 
+parameter indicates the length of the modulus in bits.  The padded data is stored in \textit{out} with a length of \textit{outlen} octets.  The output will not be 
+longer than the modulus which helps allocate the correct output buffer size.
+
+Only encryption padding requires a PRNG.  When performing signature padding the \textit{prng\_idx} parameter may be left to zero as it is not checked for validity.
+
+\subsection{PKCS \#1 v1.5 Decoding}
+The following function performs PKCS \#1 v1.5 de--padding:
+\index{pkcs\_1\_v1\_5\_decode()}
+\begin{verbatim}
+int pkcs_1_v1_5_decode(
+    const unsigned char *msg, 
+          unsigned long  msglen,
+                    int  block_type,
+          unsigned long  modulus_bitlen,
+          unsigned char *out, 
+          unsigned long *outlen,
+                    int *is_valid);
+\end{verbatim}
+\index{LTC\_PKCS\_1\_EME} \index{LTC\_PKCS\_1\_EMSA}
+This will remove the PKCS padding data pointed to by \textit{msg} of length \textit{msglen}.  The decoded data is stored in \textit{out} of length
+\textit{outlen}.  If the padding is valid, a 1 is stored in \textit{is\_valid}, otherwise, a 0 is stored.  The \textit{block\_type} parameter must be set to either
+\textbf{LTC\_PKCS\_1\_EME} or \textbf{LTC\_PKCS\_1\_EMSA} depending on whether encryption or signature padding is being removed.
+
+\mysection{PKCS \#1 v2.1 Encryption}
+PKCS \#1 RSA Encryption amounts to OAEP padding of the input message followed by the modular exponentiation.  As far as this portion of
+the library is concerned we are only dealing with th OAEP padding of the message.
+
+\subsection{OAEP Encoding}
+
+The following function performs PKCS \#1 v2.1 encryption padding:
+
+\index{pkcs\_1\_oaep\_encode()}
+\begin{alltt}
+int pkcs_1_oaep_encode(
+    const unsigned char *msg,    
+          unsigned long  msglen,
+    const unsigned char *lparam, 
+          unsigned long  lparamlen,
+          unsigned long  modulus_bitlen, 
+             prng_state *prng,
+                    int  prng_idx,
+                    int  hash_idx,
+          unsigned char *out, 
+          unsigned long *outlen);
+\end{alltt}
+
+This accepts \textit{msg} as input of length \textit{msglen} which will be OAEP padded.  The \textit{lparam} variable is an additional system specific
+tag that can be applied to the encoding.  This is useful to identify which system encoded the message.  If no variance is desired then
+\textit{lparam} can be set to \textbf{NULL}.  
+
+OAEP encoding requires the length of the modulus in bits in order to calculate the size of the output.  This is passed as the parameter
+\textit{modulus\_bitlen}.  \textit{hash\_idx} is the index into the hash descriptor table of the hash desired.  PKCS \#1 allows any hash to be 
+used but both the encoder and decoder must use the same hash in order for this to succeed.  The size of hash output affects the maximum
+ sized input message.  \textit{prng\_idx} and \textit{prng} are the random number generator arguments required to randomize the padding process.  
+The padded message is stored in \textit{out} along with the length in \textit{outlen}.
+
+If $h$ is the length of the hash and $m$ the length of the modulus (both in octets) then the maximum payload for \textit{msg} is 
+$m - 2h - 2$.  For example, with a $1024$--bit RSA key and SHA--1 as the hash the maximum payload is $86$ bytes.  
+
+Note that when the message is padded it still has not been RSA encrypted.  You must pass the output of this function to 
+rsa\_exptmod() to encrypt it. 
+
+\subsection{OAEP Decoding}
+
+\index{pkcs\_1\_oaep\_decode()}
+\begin{alltt}
+int pkcs_1_oaep_decode(
+    const unsigned char *msg,    
+          unsigned long  msglen,
+    const unsigned char *lparam, 
+          unsigned long  lparamlen,
+          unsigned long  modulus_bitlen, 
+                    int  hash_idx,
+          unsigned char *out,    
+          unsigned long *outlen,
+                    int *res);
+\end{alltt}
+
+This function decodes an OAEP encoded message and outputs the original message that was passed to the OAEP encoder.  \textit{msg} is the 
+output of pkcs\_1\_oaep\_encode() of length \textit{msglen}.  \textit{lparam} is the same system variable passed to the OAEP encoder.  If it does not
+match what was used during encoding this function will not decode the packet.  \textit{modulus\_bitlen} is the size of the RSA modulus in bits
+and must match what was used during encoding.  Similarly the \textit{hash\_idx} index into the hash descriptor table must match what was used
+during encoding.
+
+If the function succeeds it decodes the OAEP encoded message into \textit{out} of length \textit{outlen} and stores a 
+$1$ in \textit{res}.  If the packet is invalid it stores $0$ in \textit{res} and if the function fails for another reason
+it returns an error code.  
+
+\mysection{PKCS \#1 Digital Signatures}
+
+\subsection{PSS Encoding}
+PSS encoding is the second half of the PKCS \#1 standard which is padding to be applied to messages that are signed.  
+
+\index{pkcs\_1\_pss\_encode()}
+\begin{alltt}
+int pkcs_1_pss_encode(
+    const unsigned char *msghash, 
+          unsigned long  msghashlen,
+          unsigned long  saltlen,  
+             prng_state *prng,     
+                    int  prng_idx, 
+                    int  hash_idx,
+          unsigned long  modulus_bitlen,
+          unsigned char *out, 
+          unsigned long *outlen);
+\end{alltt}
+
+This function assumes the message to be PSS encoded has previously been hashed.  The input hash \textit{msghash} is of length 
+\textit{msghashlen}.  PSS allows a variable length random salt (it can be zero length) to be introduced in the signature process.  
+\textit{hash\_idx} is the index into the hash descriptor table of the hash to use.  \textit{prng\_idx} and \textit{prng} are the random
+number generator information required for the salt.
+
+Similar to OAEP encoding \textit{modulus\_bitlen} is the size of the RSA modulus (in bits).  It limits the size of the salt.  If $m$ is the length
+of the modulus $h$ the length of the hash output (in octets) then there can be $m - h - 2$ bytes of salt.  
+
+This function does not actually sign the data it merely pads the hash of a message so that it can be processed by rsa\_exptmod().
+
+\subsection{PSS Decoding}
+
+To decode a PSS encoded signature block you have to use the following.
+
+\index{pkcs\_1\_pss\_decode()}
+\begin{alltt}
+int pkcs_1_pss_decode(
+    const unsigned char *msghash, 
+          unsigned long  msghashlen,
+    const unsigned char *sig, 
+          unsigned long  siglen,
+          unsigned long  saltlen,
+                    int  hash_idx,
+          unsigned long  modulus_bitlen, 
+                    int *res);
+\end{alltt}
+This will decode the PSS encoded message in \textit{sig} of length \textit{siglen} and compare it to values in \textit{msghash} of length
+\textit{msghashlen}.  If the block is a valid PSS block and the decoded hash equals the hash supplied \textit{res} is set to non--zero.  Otherwise, 
+it is set to zero.  The rest of the parameters are as in the PSS encode call.
+
+It's important to use the same \textit{saltlen} and hash for both encoding and decoding as otherwise the procedure will not work.
+
+\mysection{RSA Key Operations}
+\subsection{Background}
+
+RSA is a public key algorithm that is based on the inability to find the \textit{e-th} root modulo a composite of unknown 
+factorization.  Normally the difficulty of breaking RSA is associated with the integer factoring problem but they are
+not strictly equivalent.
+
+The system begins with with two primes $p$ and $q$ and their product $N = pq$.  The order or \textit{Euler totient} of the
+multiplicative sub-group formed modulo $N$ is given as $\phi(N) = (p - 1)(q - 1)$ which can be reduced to 
+$\mbox{lcm}(p - 1, q - 1)$.  The public key consists of the composite $N$ and some integer $e$ such that 
+$\mbox{gcd}(e, \phi(N)) = 1$.  The private key consists of the composite $N$ and the inverse of $e$ modulo $\phi(N)$ 
+often simply denoted as $de \equiv 1\mbox{ }(\mbox{mod }\phi(N))$.
+
+A person who wants to encrypt with your public key simply forms an integer (the plaintext) $M$ such that 
+$1 < M < N-2$ and computes the ciphertext $C = M^e\mbox{ }(\mbox{mod }N)$.  Since finding the inverse exponent $d$
+given only $N$ and $e$ appears to be intractable only the owner of the private key can decrypt the ciphertext and compute
+$C^d \equiv \left (M^e \right)^d \equiv M^1 \equiv M\mbox{ }(\mbox{mod }N)$.  Similarly the owner of the private key 
+can sign a message by \textit{decrypting} it.  Others can verify it by \textit{encrypting} it.  
+
+Currently RSA is a difficult system to cryptanalyze provided that both primes are large and not close to each other.  
+Ideally $e$ should be larger than $100$ to prevent direct analysis.  For example, if $e$ is three and you do not pad
+the plaintext to be encrypted than it is possible that $M^3 < N$ in which case finding the cube-root would be trivial.  
+The most often suggested value for $e$ is $65537$ since it is large enough to make such attacks impossible and also well 
+designed for fast exponentiation (requires 16 squarings and one multiplication).
+
+It is important to pad the input to RSA since it has particular mathematical structure.  For instance  
+$M_1^dM_2^d = (M_1M_2)^d$ which can be used to forge a signature.  Suppose $M_3 = M_1M_2$ is a message you want
+to have a forged signature for.  Simply get the signatures for $M_1$ and $M_2$ on their own and multiply the result
+together.  Similar tricks can be used to deduce plaintexts from ciphertexts.  It is important not only to sign 
+the hash of documents only but also to pad the inputs with data to remove such structure.  
+
+\subsection{RSA Key Generation}
+
+For RSA routines a single \textit{rsa\_key} structure is used.  To make a new RSA key call:
+\index{rsa\_make\_key()}
+\begin{verbatim}
+int rsa_make_key(prng_state *prng, 
+                        int  wprng, 
+                        int  size, 
+                       long  e, 
+                    rsa_key *key);
+\end{verbatim}
+
+Where \textit{wprng} is the index into the PRNG descriptor array.  The \textit{size} parameter is the size in bytes of the RSA modulus desired.
+The \textit{e} parameter is the encryption exponent desired, typical values are 3, 17, 257 and 65537.  Stick with 65537 since it is big enough to prevent 
+trivial math attacks, and not super slow.  The \textit{key} parameter is where the constructed key is placed.  All keys must be at 
+least 128 bytes, and no more than 512 bytes in size (\textit{that is from 1024 to 4096 bits}).
+
+\index{rsa\_free()}
+Note: the \textit{rsa\_make\_key()} function allocates memory at run--time when you make the key.  Make sure to call 
+\textit{rsa\_free()} (see below) when you are finished with the key.  If \textit{rsa\_make\_key()} fails it will automatically 
+free the memory allocated.
+
+\index{PK\_PRIVATE} \index{PK\_PUBLIC}
+There are two types of RSA keys.  The types are {\bf PK\_PRIVATE} and {\bf PK\_PUBLIC}.  The first type is a private 
+RSA key which includes the CRT parameters\footnote{As of v0.99 the PK\_PRIVATE\_OPTIMIZED type has been deprecated, and has been replaced by the 
+PK\_PRIVATE type.} in the form of a RSAPrivateKey (PKCS \#1 compliant).  The second type, is a public RSA key which only includes the modulus and public exponent.  
+It takes the form of a RSAPublicKey (PKCS \#1 compliant).
+
+\subsection{RSA Exponentiation}
+To do raw work with the RSA function, that is without padding, use the following function:
+\index{rsa\_exptmod()}
+\begin{verbatim}
+int rsa_exptmod(const unsigned char *in,   
+                      unsigned long  inlen,
+                      unsigned char *out,  
+                      unsigned long *outlen, 
+                                int  which, 
+                            rsa_key *key);
+\end{verbatim}
+This will load the bignum from \textit{in} as a big endian integer in the format PKCS \#1 specifies, raises it to either \textit{e} or \textit{d} and stores the result
+in \textit{out} and the size of the result in \textit{outlen}. \textit{which} is set to {\bf PK\_PUBLIC} to use \textit{e} 
+(i.e. for encryption/verifying) and set to {\bf PK\_PRIVATE} to use \textit{d} as the exponent (i.e. for decrypting/signing).
+
+Note: the output of this function is zero--padded as per PKCS \#1 specification.  This allows this routine to work with PKCS \#1 padding functions properly.
+
+\mysection{RSA Key Encryption}
+Normally RSA is used to encrypt short symmetric keys which are then used in block ciphers to encrypt a message.
+To facilitate encrypting short keys the following functions have been provided.
+
+\index{rsa\_encrypt\_key()}
+\begin{verbatim}
+int rsa_encrypt_key(
+    const unsigned char *in,  
+          unsigned long  inlen,
+          unsigned char *out, 
+          unsigned long *outlen,
+    const unsigned char *lparam, 
+          unsigned long  lparamlen,
+             prng_state *prng, 
+                    int  prng_idx, 
+                    int  hash_idx, 
+                rsa_key *key);
+\end{verbatim}
+This function will OAEP pad \textit{in} of length \textit{inlen} bytes, RSA encrypt it, and store the ciphertext
+in \textit{out} of length \textit{outlen} octets.  The \textit{lparam} and \textit{lparamlen} are the same parameters you would pass
+to \index{pkcs\_1\_oaep\_encode()} pkcs\_1\_oaep\_encode().
+
+\subsection{Extended Encryption}
+As of v1.15, the library supports both v1.5 and v2.1 PKCS \#1 style paddings in these higher level functions.  The following is the extended
+encryption function:
+
+\index{rsa\_encrypt\_key\_ex()}
+\begin{verbatim}
+int rsa_encrypt_key_ex(
+    const unsigned char *in,     
+          unsigned long  inlen,
+          unsigned char *out,    
+          unsigned long *outlen,
+    const unsigned char *lparam, 
+          unsigned long  lparamlen,
+             prng_state *prng, 
+                    int  prng_idx, 
+                    int  hash_idx, 
+                    int  padding, 
+                rsa_key *key);
+\end{verbatim}
+
+\index{LTC\_PKCS\_1\_OAEP} \index{LTC\_PKCS\_1\_V1\_5}
+The parameters are all the same as for rsa\_encrypt\_key() except for the addition of the \textit{padding} parameter.  It must be set to
+\textbf{LTC\_PKCS\_1\_V1\_5} to perform v1.5 encryption, or set to \textbf{LTC\_PKCS\_1\_OAEP} to perform v2.1 encryption.
+
+When performing v1.5 encryption, the hash and lparam parameters are totally ignored and can be set to \textbf{NULL} or zero (respectively).
+
+\mysection{RSA Key Decryption}
+\index{rsa\_decrypt\_key()}
+\begin{verbatim}
+int rsa_decrypt_key(
+    const unsigned char *in, 
+          unsigned long  inlen,
+          unsigned char *out, 
+          unsigned long *outlen, 
+    const unsigned char *lparam, 
+          unsigned long  lparamlen,
+                    int  hash_idx, 
+                    int *stat,
+                rsa_key *key);
+\end{verbatim}
+This function will RSA decrypt \textit{in} of length \textit{inlen} then OAEP de-pad the resulting data and store it in
+\textit{out} of length \textit{outlen}.  The \textit{lparam} and \textit{lparamlen} are the same parameters you would pass
+to pkcs\_1\_oaep\_decode().
+
+If the RSA decrypted data is not a valid OAEP packet then \textit{stat} is set to $0$.  Otherwise, it is set to $1$.
+
+\subsection{Extended Decryption}
+As of v1.15, the library supports both v1.5 and v2.1 PKCS \#1 style paddings in these higher level functions.  The following is the extended
+decryption function:
+
+\index{rsa\_decrypt\_key\_ex()}
+\begin{verbatim}
+int rsa_decrypt_key_ex(
+    const unsigned char *in,       
+          unsigned long  inlen,
+          unsigned char *out,      
+          unsigned long *outlen,
+    const unsigned char *lparam,   
+          unsigned long  lparamlen,
+                    int  hash_idx, 
+                    int  padding,
+                    int *stat,
+                rsa_key *key);
+\end{verbatim}
+
+Similar to the extended encryption, the new parameter \textit{padding} indicates which version of the PKCS \#1 standard to use.  
+It must be set to \textbf{LTC\_PKCS\_1\_V1\_5} to perform v1.5 decryption, or set to \textbf{LTC\_PKCS\_1\_OAEP} to perform v2.1 decryption.
+
+When performing v1.5 decryption, the hash and lparam parameters are totally ignored and can be set to \textbf{NULL} or zero (respectively).
+
+
+\mysection{RSA Signature Generation}
+Similar to RSA key encryption RSA is also used to \textit{digitally sign} message digests (hashes).  To facilitate this
+process the following functions have been provided.
+
+\index{rsa\_sign\_hash()}
+\begin{verbatim}
+int rsa_sign_hash(const unsigned char *in, 
+                        unsigned long  inlen, 
+                        unsigned char *out,  
+                        unsigned long *outlen, 
+                           prng_state *prng,     
+                                  int  prng_idx,
+                                  int  hash_idx, 
+                        unsigned long  saltlen,
+                              rsa_key *key);
+\end{verbatim}
+
+This will PSS encode the message digest pointed to by \textit{in} of length \textit{inlen} octets.  Next, the PSS encoded hash will be RSA 
+\textit{signed} and the output stored in the buffer pointed to by \textit{out} of length \textit{outlen} octets.  
+
+The \textit{hash\_idx} parameter indicates which hash will be used to create the PSS encoding.  It should be the same as the hash used to
+hash the message being signed.  The \textit{saltlen} parameter indicates the length of the desired salt, and should typically be small.  A good
+default value is between 8 and 16 octets.  Strictly, it must be small than $modulus\_len - hLen - 2$ where \textit{modulus\_len} is the size of
+the RSA modulus (in octets), and \textit{hLen} is the length of the message digest produced by the chosen hash.  
+
+\subsection{Extended Signatures}
+
+As of v1.15, the library supports both v1.5 and v2.1 signatures.  The extended signature generation function has the following prototype:
+
+\index{rsa\_sign\_hash\_ex()}
+\begin{verbatim}
+int rsa_sign_hash_ex(
+    const unsigned char *in,       
+          unsigned long  inlen,
+          unsigned char *out,      
+          unsigned long *outlen,
+                    int  padding,
+          prng_state    *prng,     
+                    int  prng_idx,
+                    int  hash_idx, 
+          unsigned long  saltlen,
+                rsa_key *key);
+\end{verbatim}
+
+This will PKCS encode the message digest pointed to by \textit{in} of length \textit{inlen} octets.  Next, the PKCS encoded hash will be RSA 
+\textit{signed} and the output stored in the buffer pointed to by \textit{out} of length \textit{outlen} octets.  The \textit{padding} parameter
+must be set to \textbf{LTC\_PKCS\_1\_V1\_5} to produce a v1.5 signature, otherwise, it must be set to \textbf{LTC\_PKCS\_1\_PSS} to produce a 
+v2.1 signature.
+
+When performing a v1.5 signature the \textit{prng}, \textit{prng\_idx}, and \textit{hash\_idx} parameters are not checked and can be left to any
+values such as $\lbrace$\textbf{NULL}, 0, 0$\rbrace$.
+
+\mysection{RSA Signature Verification}
+\index{rsa\_verify\_hash()}
+\begin{verbatim}
+int rsa_verify_hash(const unsigned char *sig, 
+                          unsigned long  siglen,
+                    const unsigned char *msghash,  
+                          unsigned long  msghashlen,

+                                rsa_key *key);
+\end{verbatim}
+
+This will RSA \textit{verify} the signature pointed to by \textit{sig} of length \textit{siglen} octets.  Next, the RSA decoded data is PSS decoded
+and the extracted hash is compared against the message digest pointed to by \textit{msghash} of length \textit{msghashlen} octets.
+
+If the RSA decoded data is not a valid PSS message, or if the PSS decoded hash does not match the \textit{msghash} 
+value, \textit{res} is set to $0$.  Otherwise, if the function succeeds, and signature is valid \textit{res} is set to $1$.
+
+\subsection{Extended Verification}
+
+As of v1.15, the library supports both v1.5 and v2.1 signature verification.  The extended signature verification function has the following prototype:
+
+\index{rsa\_verify\_hash\_ex()}
+\begin{verbatim}
+int rsa_verify_hash_ex(
+    const unsigned char *sig,      
+          unsigned long  siglen,
+    const unsigned char *hash,     
+          unsigned long  hashlen,
+                    int  padding,
+                    int  hash_idx, 
+          unsigned long  saltlen,
+                    int *stat,     
+                rsa_key *key);
+\end{verbatim}
+
+This will RSA \textit{verify} the signature pointed to by \textit{sig} of length \textit{siglen} octets.  Next, the RSA decoded data is PKCS decoded
+and the extracted hash is compared against the message digest pointed to by \textit{msghash} of length \textit{msghashlen} octets.
+
+If the RSA decoded data is not a valid PSS message, or if the PKCS decoded hash does not match the \textit{msghash} 
+value, \textit{res} is set to $0$.  Otherwise, if the function succeeds, and signature is valid \textit{res} is set to $1$.
+
+The \textit{padding} parameter must be set to \textbf{LTC\_PKCS\_1\_V1\_5} to perform a v1.5 verification.  Otherwise, it must be set to 
+\textbf{LTC\_PKCS\_1\_PSS} to perform a v2.1 verification.  When performing a v1.5 verification the \textit{hash\_idx} parameter is ignored.

+}
+\end{verbatim}
+\end{small}
+
+\mysection{RSA Key Format}
+
+The RSA key format adopted for exporting and importing keys is the PKCS \#1 format defined by the ASN.1 constructs known as 
+RSAPublicKey and RSAPrivateKey.  Additionally, the OpenSSL key format is supported by the import function only.
+
+\subsection{RSA Key Export}
+To export a RSA key use the following function.
+
+\index{rsa\_export()}
+\begin{verbatim}
+int rsa_export(unsigned char *out, 
+               unsigned long *outlen, 
+                         int  type, 
+                     rsa_key *key);
+\end{verbatim}
+This will export the RSA key in either a RSAPublicKey or RSAPrivateKey (PKCS \#1 types) depending on the value of \textit{type}.  When it is 
+set to \textbf{PK\_PRIVATE} the export format will be RSAPrivateKey and otherwise it will be RSAPublicKey.
+
+\subsection{RSA Key Import}
+To import a RSA key use the following function.
+
+\index{rsa\_import()}
+\begin{verbatim}
+int rsa_import(const unsigned char *in, 
+                     unsigned long  inlen, 
+                           rsa_key *key);
+\end{verbatim}
+
+This will import the key stored in \textit{inlen} and import it to \textit{key}.  If the function fails it will automatically free any allocated memory.  This
+function can import both RSAPublicKey and RSAPrivateKey formats.
+
+As of v1.06 this function can also import OpenSSL DER formatted public RSA keys.  They are essentially encapsulated RSAPublicKeys.  LibTomCrypt will
+import the key, strip off the additional data (it's the preferred hash) and fill in the rsa\_key structure as if it were a native RSAPublicKey.  Note that
+there is no function provided to export in this format.  
+
+\chapter{Elliptic Curve Cryptography}
+
+\mysection{Background}
+The library provides a set of core ECC functions as well that are designed to be the Elliptic Curve analogy of all of the 
+Diffie-Hellman routines in the previous chapter.  Elliptic curves (of certain forms) have the benefit that they are harder
+to attack (no sub-exponential attacks exist unlike normal DH crypto) in fact the fastest attack requires the square root
+of the order of the base point in time.  That means if you use a base point of order $2^{192}$ (which would represent a
+192-bit key) then the work factor is $2^{96}$ in order to find the secret key.
+
+The curves in this library are taken from the following website:
+\begin{verbatim}
+http://csrc.nist.gov/cryptval/dss.htm
+\end{verbatim}
+
+As of v1.15 three new curves from the SECG standards are also included they are the secp112r1, secp128r1, and secp160r1 curves.  These curves were added to 
+support smaller devices which do not need as large keys for security.
+
+They are all curves over the integers modulo a prime.  The curves have the basic equation that is:
+\begin{equation}
+y^2 = x^3 - 3x + b\mbox{ }(\mbox{mod }p)
+\end{equation}
+
+The variable $b$ is chosen such that the number of points is nearly maximal.  In fact the order of the base points $\beta$ 
+provided are very close to $p$ that is $\vert \vert \phi(\beta) \vert \vert \approx \vert \vert p \vert \vert$.  The curves
+range in order from $\approx 2^{112}$ points to $\approx 2^{521}$.  According to the source document any key size greater
+than or equal to 256-bits is sufficient for long term security.  
+
+\mysection{Fixed Point Optimizations}
+\index{Fixed Point ECC}
+\index{MECC\_FP}
+As of v1.12 of LibTomCrypt, support for Fixed Point ECC point multiplication has been added.  It is a generic optimization that is
+supported by any conforming math plugin.  It is enabled by defining \textbf{MECC\_FP} during the build, such as 
+
+\begin{verbatim}
+CFLAGS="-DTFM_DESC -DMECC_FP" make 
+\end{verbatim}
+
+which will build LTC using the TFM math library and enabling this new feature.  The feature is not enabled by default as it is \textbf{NOT} thread
+safe (by default).  It supports the LTC locking macros (such as by enabling LTC\_PTHREAD), but by default is not locked.
+
+\index{FP\_ENTRIES}
+The optimization works by using a Fixed Point multiplier on any base point you use twice or more in a short period of time.  It has a limited size
+cache (of FP\_ENTRIES entries) which it uses to hold recent bases passed to ltc\_ecc\_mulmod().  Any base detected to be used twice is sent through the
+pre--computation phase, and then the fixed point algorithm can be used.  For example, if you use a NIST base point twice in a row, the 2$^{nd}$ and 
+all subsequent point multiplications with that point will use the faster algorithm.
+
+\index{FP\_LUT}
+The optimization uses a window on the multiplicand of FP\_LUT bits (default: 8, min: 2, max: 12), and this controls the memory/time trade-off. The larger the 
+value the faster the algorithm will be but the more memory it will take.  The memory usage is $3 \cdot 2^{FP\_LUT}$ integers which by default
+with TFM amounts to about 400kB of memory.  Tuning TFM (by changing FP\_SIZE) can decrease the usage by a fair amount.  Memory is only used by a cache entry
+if it is active.  Both FP\_ENTRIES and FP\_LUT are definable on the command line if you wish to override them. For instance,
+
+\begin{verbatim}
+CFLAGS="-DTFM_DESC -DMECC_FP -DFP_ENTRIES=8 -DFP_LUT=6" make
+\end{verbatim}
+
+\begin{flushleft} 
+\index{FP\_SIZE} \index{TFM} \index{tfm.h}
+would define a window of 6 bits and limit the cache to 8 entries.  Generally, it is better to first tune TFM by adjusting FP\_SIZE (from tfm.h).  It defaults
+to 4096 bits (512 bytes) which is way more than what is required by ECC.  At most, you need 1152 bits to accommodate ECC--521.  If you're only using (say)
+ECC--256 you will only need 576 bits, which would reduce the memory usage by 700\%.
+\end{flushleft}
+
+\mysection{Key Format}
+LibTomCrypt uses a unique format for ECC public and private keys.  While ANSI X9.63 partially specifies key formats, it does it in a less than ideally simple manner.  \
+In the case of LibTomCrypt, it is meant \textbf{solely} for NIST and SECG $GF(p)$ curves.  The format of the keys is as follows:
+
+\index{ECC Key Format}
+\begin{small}
+\begin{verbatim}
+ECCPublicKey ::= SEQUENCE {
+    flags       BIT STRING(0), -- public/private flag (always zero), 
+    keySize     INTEGER,       -- Curve size (in bits) divided by eight 
+                               -- and rounded down, e.g. 521 => 65
+    pubkey.x    INTEGER,       -- The X co-ordinate of the public key point
+    pubkey.y    INTEGER,       -- The Y co-ordinate of the public key point
+}
+
+ECCPrivateKey ::= SEQUENCE {
+    flags       BIT STRING(1), -- public/private flag (always one), 
+    keySize     INTEGER,       -- Curve size (in bits) divided by eight 
+                               -- and rounded down, e.g. 521 => 65
+    pubkey.x    INTEGER,       -- The X co-ordinate of the public key point
+    pubkey.y    INTEGER,       -- The Y co-ordinate of the public key point
+    secret.k    INTEGER,       -- The secret key scalar
+}
+\end{verbatim}
+\end{small}
+
+The first flags bit denotes whether the key is public (zero) or private (one).  
+
+\vfil
+
+\mysection{ECC Curve Parameters}
+The library uses the following structure to describe an elliptic curve.  This is used internally, as well as by the new
+extended ECC functions which allow the user to specify their own curves. 
+
+\index{ltc\_ecc\_set\_type}
+\begin{verbatim}
+/** Structure defines a NIST GF(p) curve */
+typedef struct {
+   /** The size of the curve in octets */
+   int size;
+
+   /** name of curve */
+   char *name; 
+
+   /** The prime that defines the field (encoded in hex) */
+   char *prime;
+
+   /** The fields B param (hex) */
+   char *B;
+
+   /** The order of the curve (hex) */
+   char *order;
+  
+   /** The x co-ordinate of the base point on the curve (hex) */
+   char *Gx;
+ 
+   /** The y co-ordinate of the base point on the curve (hex) */
+   char *Gy;
+} ltc_ecc_set_type;
+\end{verbatim}
+
+The curve must be of the form $y^2 = x^3 - 3x + b$, and all of the integer parameters are encoded in hexadecimal format.
+
+\mysection{Core Functions}
+\subsection{ECC Key Generation}
+There is a key structure called \textit{ecc\_key} used by the ECC functions.  There is a function to make a key:
+\index{ecc\_make\_key()}
+\begin{verbatim}
+int ecc_make_key(prng_state *prng, 
+                        int  wprng, 
+                        int  keysize, 
+                    ecc_key *key);
+\end{verbatim}
+
+The \textit{keysize} is the size of the modulus in bytes desired.  Currently directly supported values are 12, 16, 20, 24, 28, 32, 48, and 65 bytes which
+correspond to key sizes of 112, 128, 160, 192, 224, 256, 384, and 521 bits respectively.  If you pass a key size that is between any key size it will round 
+the keysize up to the next available one.
+
+The function will free any internally allocated resources if there is an error.
+
+\subsection{Extended Key Generation}
+As of v1.16, the library supports an extended key generation routine which allows the user to specify their own curve.  It is specified as follows:
+
+\index{ecc\_make\_key\_ex()}
+\begin{verbatim}
+int  ecc_make_key_ex(
+                 prng_state *prng, 
+                        int  wprng, 
+                    ecc_key *key, 
+     const ltc_ecc_set_type *dp);
+\end{verbatim}
+
+This function generates a random ECC key over the curve specified by the parameters by \textit{dp}.  The rest of the parameters are equivalent to
+those from the original key generation function.
+
+\subsection{ECC Key Free}
+To free the memory allocated by a ecc\_make\_key(), ecc\_make\_key\_ex(), ecc\_import(), or ecc\_import\_ex() call use the following function:
+\index{ecc\_free()}
+\begin{verbatim}
+void ecc_free(ecc_key *key);
+\end{verbatim}
+
+\subsection{ECC Key Export}
+To export an ECC key using the LibTomCrypt format call the following function:
+\index{ecc\_export()}
+\begin{verbatim}
+int ecc_export(unsigned char *out, 
+               unsigned long *outlen, 
+                         int  type, 
+                     ecc_key *key);
+\end{verbatim}
+This will export the key with the given \textit{type} (\textbf{PK\_PUBLIC} or \textbf{PK\_PRIVATE}), and store it to \textit{out}.  
+
+\subsection{ECC Key Import}
+The following function imports a LibTomCrypt format ECC key:
+\index{ecc\_import()}
+\begin{verbatim}
+int ecc_import(const unsigned char *in, 
+                     unsigned long  inlen, 
+                           ecc_key *key);
+\end{verbatim}
+This will import the ECC key from \textit{in}, and store it in the ecc\_key structure pointed to by \textit{key}.  If the operation fails it will free
+any allocated memory automatically.
+
+\subsection{Extended Key Import}
+
+The following function imports a LibTomCrypt format ECC key using a specified set of curve parameters:
+\index{ecc\_import\_ex()}
+\begin{verbatim}
+int  ecc_import_ex(const unsigned char *in, 
+                         unsigned long  inlen, 
+                               ecc_key *key, 
+                const ltc_ecc_set_type *dp);
+\end{verbatim}
+This will import the key from the array pointed to by \textit{in} of length \textit{inlen} octets.  The key is stored in
+the ECC structure pointed to by \textit{key}.  The curve is specified by the parameters pointed to by \textit{dp}.  The function will free
+all internally allocated memory upon error.
+
+\subsection{ANSI X9.63 Export}
+The following function exports an ECC public key in the ANSI X9.63 format:
+
+\index{ecc\_ansi\_x963\_export()}
+\begin{verbatim}
+int ecc_ansi_x963_export(      ecc_key *key, 
+                         unsigned char *out, 
+                         unsigned long *outlen);
+\end{verbatim}
+The ECC key pointed to by \textit{key} is exported in public fashion to the array pointed to by \textit{out}.  The ANSI X9.63 format used is from
+section 4.3.6 of the standard.  It does not allow for the export of private keys.
+
+\subsection{ANSI X9.63 Import}
+The following function imports an ANSI X9.63 section 4.3.6 format public ECC key:
+
+\index{ecc\_ansi\_x963\_import()}
+\begin{verbatim}
+int ecc_ansi_x963_import(const unsigned char *in, 
+                               unsigned long  inlen, 
+                                     ecc_key *key);
+\end{verbatim}
+This will import the key stored in the array pointed to by \textit{in} of length \textit{inlen} octets.  The imported key is stored in the ECC key pointed to by 
+\textit{key}.  The function will free any allocated memory upon error.
+
+\subsection{Extended ANSI X9.63 Import}
+The following function allows the importing of an ANSI x9.63 section 4.3.6 format public ECC key using user specified domain parameters:
+
+\index{ecc\_ansi\_x963\_import\_ex()}
+\begin{verbatim}
+int ecc_ansi_x963_import_ex(const unsigned char *in, 
+                                  unsigned long  inlen, 
+                                        ecc_key *key, 
+                               ltc_ecc_set_type *dp);
+\end{verbatim}
+This will import the key stored in the array pointed to by \textit{in} of length \textit{inlen} octets using the domain parameters pointed to by \textit{dp}.  
+The imported key is stored in the ECC key pointed to by \textit{key}.  The function will free any allocated memory upon error.
+
+\subsection{ECC Shared Secret}
+To construct a Diffie-Hellman shared secret with a private and public ECC key, use the following function:
+\index{ecc\_shared\_secret()}
+\begin{verbatim}
+int ecc_shared_secret(      ecc_key *private_key, 
+                            ecc_key *public_key, 
+                      unsigned char *out, 
+                      unsigned long *outlen);
+\end{verbatim}
+The \textit{private\_key} is typically the local private key, and \textit{public\_key} is the key the remote party has shared.   
+Note: this function stores only the $x$ co-ordinate of the shared elliptic point as described in ANSI X9.63 ECC--DH.  
+
+\mysection{ECC Diffie-Hellman Encryption}
+ECC--DH Encryption is performed by producing a random key, hashing it, and XOR'ing the digest against the plaintext.  It is not strictly ANSI X9.63 compliant
+but it is very similar.  It has been extended by using an ASN.1 sequence and hash object identifiers to allow portable usage.  The following function
+encrypts a short string (no longer than the message digest) using this technique:
+
+\subsection{ECC-DH Encryption}
+\index{ecc\_encrypt\_key()}

+
+As the name implies this function encrypts a (symmetric) key, and is not intended for encrypting long messages directly.  It will encrypt the 
+plaintext in the array pointed to by \textit{in} of length \textit{inlen} octets.  It uses the public ECC key pointed to by \textit{key}, and
+hash algorithm indexed by \textit{hash} to construct a shared secret which may be XOR'ed against the plaintext.  The ciphertext is stored in
+the output buffer pointed to by \textit{out} of length \textit{outlen} octets.
+
+The data is encrypted to the public ECC \textit{key} such that only the holder of the private key can decrypt the payload.  To have multiple 
+recipients multiple call to this function for each public ECC key is required.

+\end{verbatim}
+
+This function will decrypt an encrypted payload.  The \textit{key} provided must be the private key corresponding to the public key
+used during encryption.  If the wrong key is provided the function will not specifically return an error code.  It is important
+to use some form of challenge response in that case (e.g. compute a MAC of a known string).
+
+\subsection{ECC Encryption Format}
+The packet format for the encrypted keys is the following ASN.1 SEQUENCE:
+
+\begin{verbatim}
+ECCEncrypt ::= SEQUENCE {
+   hashID        OBJECT IDENTIFIER, -- OID of hash used
+   pubkey        OCTET STRING     , -- Encapsulated ECCPublicKey

+}
+\end{verbatim}
+
+\mysection{EC DSA Signatures}
+
+There are also functions to sign and verify messages.  They use the ANSI X9.62 EC-DSA algorithm to generate and verify signatures in the
+ANSI X9.62 format.  
+
+\subsection{EC-DSA Signature Generation}
+To sign a message digest (hash) use the following function:
+
+\index{ecc\_sign\_hash()}
+\begin{verbatim}
+int ecc_sign_hash(const unsigned char *in,  
+                        unsigned long  inlen,
+                        unsigned char *out, 
+                        unsigned long *outlen,
+                           prng_state *prng, 
+                                  int  wprng, 
+                              ecc_key *key);
+\end{verbatim}
+
+This function will EC--DSA sign the message digest stored in the array pointed to by \textit{in} of length \textit{inlen} octets.  The signature
+will be stored in the array pointed to by \textit{out} of length \textit{outlen} octets.  The function requires a properly seeded PRNG, and 
+the ECC \textit{key} provided must be a private key.
+
+\subsection{EC-DSA Signature Verification}
+\index{ecc\_verify\_hash()}
+\begin{verbatim}
+int ecc_verify_hash(const unsigned char *sig, 
+                          unsigned long  siglen,
+                    const unsigned char *hash, 
+                          unsigned long  hashlen, 
+                                    int *stat, 
+                                ecc_key *key);
+\end{verbatim}
+
+This function will verify the EC-DSA signature in the array pointed to by \textit{sig} of length \textit{siglen} octets, against the message digest 
+pointed to by the array \textit{hash} of length \textit{hashlen}.  It will store a non--zero value in \textit{stat} if the signature is valid.  Note: 
+the function will not return an error if the signature is invalid.  It will return an error, if the actual signature payload is an invalid format.  
+The ECC \textit{key} must be the public (or private) ECC key corresponding to the key that performed the signature.
+
+\subsection{Signature Format}
+The signature code is an implementation of X9.62 EC--DSA, and the output is compliant for GF(p) curves.
+
+\mysection{ECC Keysizes}
+With ECC if you try to sign a hash that is bigger than your ECC key you can run into problems.  The math will still work, and in effect the signature will still 
+work.  With ECC keys the strength of the signature is limited by the size of the hash, or the size of they key, whichever is smaller.  For example, if you sign with 
+SHA256 and an ECC-192 key, you in effect have 96--bits of security.  
+
+The library will not warn you if you make this mistake, so it is important to check yourself before using the signatures.
+
+\chapter{Digital Signature Algorithm}
+\mysection{Introduction}
+The Digital Signature Algorithm (or DSA) is a variant of the ElGamal Signature scheme which has been modified to 
+reduce the bandwidth of the signatures.  For example, to have \textit{80-bits of security} with ElGamal, you need a group with an order of at least 1024--bits.  
+With DSA, you need a group of order at least 160--bits.  By comparison, the ElGamal signature would require at least 256 bytes of storage, whereas the DSA signature 
+would require only at least 40 bytes.  
+
+\mysection{Key Format}
+Since no useful public standard for DSA key storage was presented to me during the course of this development I made my own ASN.1 SEQUENCE which I document
+now so that others can interoperate with this library.
+
+\begin{verbatim}
+DSAPublicKey ::= SEQUENCE {
+    publicFlags    BIT STRING(0), -- must be 0
+    g              INTEGER      , -- base generator
+                                  -- check that g^q mod p == 1
+                                  -- and that 1 < g < p - 1
+    p              INTEGER      , -- prime modulus 
+    q              INTEGER      , -- order of sub-group 
+                                  -- (must be prime)
+    y              INTEGER      , -- public key, specifically, 
+                                  -- g^x mod p, 
+                                  -- check that y^q mod p == 1
+                                  -- and that 1 < y < p - 1
+}
+
+DSAPrivateKey ::= SEQUENCE {
+    publicFlags    BIT STRING(1), -- must be 1
+    g              INTEGER      , -- base generator
+                                  -- check that g^q mod p == 1
+                                  -- and that 1 < g < p - 1
+    p              INTEGER      , -- prime modulus 
+    q              INTEGER      , -- order of sub-group 
+                                  -- (must be prime)
+    y              INTEGER      , -- public key, specifically, 
+                                  -- g^x mod p, 
+                                  -- check that y^q mod p == 1
+                                  -- and that 1 < y < p - 1
+    x              INTEGER        -- private key
+}
+\end{verbatim}
+
+The leading BIT STRING has a single bit in it which is zero for public keys and one for private keys.  This makes the structure uniquely decodable, 
+and easy to work with.
+
+\mysection{Key Generation}
+To make a DSA key you must call the following function
+\begin{verbatim}
+int dsa_make_key(prng_state *prng, 
+                        int  wprng, 
+                        int  group_size, 
+                        int  modulus_size, 
+                    dsa_key *key);
+\end{verbatim}
+The variable \textit{prng} is an active PRNG state and \textit{wprng} the index to the descriptor.  \textit{group\_size} and 
+\textit{modulus\_size} control the difficulty of forging a signature.  Both parameters are in bytes.  The larger the
+\textit{group\_size} the more difficult a forgery becomes upto a limit.  The value of $group\_size$ is limited by 
+$15 < group\_size < 1024$ and $modulus\_size - group\_size < 512$.  Suggested values for the pairs are as follows.
+
+\begin{figure}[here]
+\begin{center}
+\begin{tabular}{|c|c|c|}
+\hline \textbf{Bits of Security} & \textbf{group\_size} & \textbf{modulus\_size} \\
+\hline 80  & 20 & 128 \\
+\hline 120 & 30 & 256 \\
+\hline 140 & 35 & 384 \\
+\hline 160 & 40 & 512 \\
+\hline
+\end{tabular}
+\end{center}
+\caption{DSA Key Sizes}
+\end{figure}
+
+When you are finished with a DSA key you can call the following function to free the memory used.
+\index{dsa\_free()}
+\begin{verbatim}
+void dsa_free(dsa_key *key);
+\end{verbatim}
+
+\mysection{Key Verification}
+Each DSA key is composed of the following variables.
+
+\begin{enumerate}
+  \item $q$ a small prime of magnitude $256^{group\_size}$.  
+  \item $p = qr + 1$ a large prime of magnitude $256^{modulus\_size}$ where $r$ is a random even integer.
+  \item $g = h^r \mbox{ (mod }p\mbox{)}$ a generator of order $q$ modulo $p$.  $h$ can be any non-trivial random 
+        value.  For this library they start at $h = 2$ and step until $g$ is not $1$.
+  \item $x$ a random secret (the secret key) in the range $1 < x < q$ 
+  \item $y = g^x \mbox{ (mod }p\mbox{)}$ the public key.
+\end{enumerate}
+
+A DSA key is considered valid if it passes all of the following tests.
+
+\begin{enumerate}
+   \item $q$ must be prime.
+   \item $p$ must be prime.
+   \item $g$ cannot be one of $\lbrace -1, 0, 1 \rbrace$ (modulo $p$).
+   \item $g$ must be less than $p$.
+   \item $(p-1) \equiv 0 \mbox{ (mod }q\mbox{)}$.
+   \item $g^q \equiv 1 \mbox{ (mod }p\mbox{)}$.
+   \item $1 < y < p - 1$
+   \item $y^q \equiv 1 \mbox{ (mod }p\mbox{)}$.
+\end{enumerate}
+
+Tests one and two ensure that the values will at least form a field which is required for the signatures to  
+function.  Tests three and four ensure that the generator $g$ is not set to a trivial value which would make signature
+forgery easier.  Test five ensures that $q$ divides the order of multiplicative sub-group of $\Z/p\Z$. Test six
+ensures that the generator actually generates a prime order group.  Tests seven and eight ensure that the public key
+is within range and belongs to a group of prime order.  Note that test eight does not prove that $g$ generated $y$ only
+that $y$ belongs to a multiplicative sub-group of order $q$. 
+
+The following function will perform these tests.
+
+\index{dsa\_verify\_key()}
+\begin{verbatim}
+int dsa_verify_key(dsa_key *key, int *stat);
+\end{verbatim}
+
+This will test \textit{key} and store the result in \textit{stat}.  If the result is $stat = 0$ the DSA key failed one of the tests
+and should not be used at all.  If the result is $stat = 1$ the DSA key is valid (as far as valid mathematics are concerned).
+
+\mysection{Signatures}
+\subsection{Signature Generation}
+To generate a DSA signature call the following function:
+
+\index{dsa\_sign\_hash()}
+\begin{verbatim}
+int dsa_sign_hash(const unsigned char *in,  
+                        unsigned long  inlen,
+                        unsigned char *out, 
+                        unsigned long *outlen,
+                           prng_state *prng, 
+                                  int  wprng, 
+                              dsa_key *key);
+\end{verbatim}
+
+Which will sign the data in \textit{in} of length \textit{inlen} bytes.  The signature is stored in \textit{out} and the size
+of the signature in \textit{outlen}.  If the signature is longer than the size you initially specify in \textit{outlen} nothing
+is stored and the function returns an error code.  The DSA \textit{key} must be of the \textbf{PK\_PRIVATE} persuasion.
+
+\subsection{Signature Verification}
+To verify a hash created with that function use the following function:
+
+\index{dsa\_verify\_hash()} 
+\begin{verbatim}
+int dsa_verify_hash(const unsigned char *sig, 
+                          unsigned long  siglen,
+                    const unsigned char *hash, 
+                          unsigned long  inlen, 
+                                    int *stat, 
+                                dsa_key *key);
+\end{verbatim}
+Which will verify the data in \textit{hash} of length \textit{inlen} against the signature stored in \textit{sig} of length \textit{siglen}.  
+It will set \textit{stat} to $1$ if the signature is valid, otherwise it sets \textit{stat} to $0$.  
+
+\mysection{DSA Encrypt and Decrypt}
+As of version 1.07, the DSA keys can be used to encrypt and decrypt small payloads.  It works similar to the ECC encryption where
+a shared key is computed, and the hash of the shared key XOR'ed against the plaintext forms the ciphertext.  The format used is functional port of
+the ECC encryption format to the DSA algorithm.
+
+\subsection{DSA Encryption}
+This function will encrypt a small payload with a recipients public DSA key.
+
+\index{dsa\_encrypt\_key()}
+\begin{verbatim}
+int dsa_encrypt_key(const unsigned char *in, 
+                          unsigned long  inlen,
+                          unsigned char *out,  
+                          unsigned long *outlen, 
+                             prng_state *prng, 
+                                    int  wprng, 
+                                    int  hash, 
+                                dsa_key *key);
+\end{verbatim}
+
+This will encrypt the payload in \textit{in} of length \textit{inlen} and store the ciphertext in the output buffer \textit{out}.  The
+length of the ciphertext \textit{outlen} must be originally set to the length of the output buffer.  The DSA \textit{key} can be 
+a public key.
+
+\subsection{DSA Decryption}
+
+\index{dsa\_decrypt\_key()}
+\begin{verbatim}                      
+int dsa_decrypt_key(const unsigned char *in,  
+                          unsigned long  inlen,
+                          unsigned char *out, 
+                          unsigned long *outlen, 
+                                dsa_key *key);
+\end{verbatim}
+This will decrypt the ciphertext \textit{in} of length \textit{inlen}, and store the original payload in \textit{out} of length \textit{outlen}.  
+The DSA \textit{key} must be a private key.
+
+\mysection{DSA Key Import and Export}
+
+\subsection{DSA Key Export}
+To export a DSA key so that it can be transported use the following function:
+\index{dsa\_export()}
+\begin{verbatim}
+int dsa_export(unsigned char *out, 
+               unsigned long *outlen, 
+                         int  type, 
+                     dsa_key *key);
+\end{verbatim}
+This will export the DSA \textit{key} to the buffer \textit{out} and set the length in \textit{outlen} (which must have been previously
+initialized to the maximum buffer size).  The \textit{type} variable may be either \textbf{PK\_PRIVATE} or \textbf{PK\_PUBLIC}
+depending on whether you want to export a private or public copy of the DSA key.
+
+\subsection{DSA Key Import}
+To import an exported DSA key use the following function
+:
+\index{dsa\_import()}
+\begin{verbatim}
+int dsa_import(const unsigned char *in, 
+                     unsigned long  inlen, 
+                           dsa_key *key);
+\end{verbatim}
+
+This will import the DSA key from the buffer \textit{in} of length \textit{inlen} to the \textit{key}.  If the process fails the function
+will automatically free all of the heap allocated in the process (you don't have to call dsa\_free()).  
+
+\chapter{Standards Support}
+\mysection{ASN.1 Formats}
+LibTomCrypt supports a variety of ASN.1 data types encoded with the Distinguished Encoding Rules (DER) suitable for various cryptographic protocols.  The data types
+are all provided with three basic functions with \textit{similar} prototypes.  One function has been dedicated to calculate the length in octets of a given
+format, and two functions have been dedicated to encoding and decoding the format.  
+
+On top of the basic data types are the SEQUENCE and SET data types which are collections of other ASN.1 types.  They are provided 
+in the same manner as the other data types except they use list of objects known as the \textbf{ltc\_asn1\_list} structure.  It is defined as the following:
+
+\index{ltc\_asn1\_list structure}
+\begin{verbatim}
+typedef struct {
+   int                    type;
+   void                  *data;
+   unsigned long          size;
+   int                    used;
+   struct ltc_asn1_list_ *prev,  *next, 
+                         *child, *parent;
+} ltc_asn1_list;
+\end{verbatim}
+
+\index{LTC\_SET\_ASN1 macro}
+The \textit{type} field is one of the following ASN.1 field definitions.  The \textit{data} pointer is a void pointer to the data to be encoded (or the destination) and the 
+\textit{size} field is specific to what you are encoding (e.g. number of bits in the BIT STRING data type).  The \textit{used} field is primarily for the CHOICE decoder
+and reflects if the particular member of a list was the decoded data type.  To help build the lists in an orderly fashion the macro
+\textit{LTC\_SET\_ASN1(list, index, Type, Data, Size)} has been provided.
+
+It will assign to the \textit{index}th position in the \textit{list} the triplet (Type, Data, Size).  An example usage would be:
+
+\begin{small}
+\begin{verbatim}
+...
+ltc_asn1_list   sequence[3];
+unsigned long   three=3;
+
+LTC_SET_ASN1(sequence, 0, LTC_ASN1_IA5_STRING,    "hello", 5);
+LTC_SET_ASN1(sequence, 1, LTC_ASN1_SHORT_INTEGER, &three,  1);
+LTC_SET_ASN1(sequence, 2, LTC_ASN1_NULL,           NULL,   0);
+\end{verbatim}
+\end{small}
+
+The macro is relatively safe with respect to modifying variables, for instance the following code is equivalent.
+
+\begin{small}
+\begin{verbatim}
+...
+ltc_asn1_list   sequence[3];
+unsigned long   three=3;
+int             x=0;
+LTC_SET_ASN1(sequence, x++, LTC_ASN1_IA5_STRING,    "hello", 5);
+LTC_SET_ASN1(sequence, x++, LTC_ASN1_SHORT_INTEGER, &three,  1);
+LTC_SET_ASN1(sequence, x++, LTC_ASN1_NULL,           NULL,   0);
+\end{verbatim}
+\end{small}
+

+
+\subsection{SEQUENCE Type}
+The SEQUENCE data type is a collection of other ASN.1 data types encapsulated with a small header which is a useful way of sending multiple data types in one packet.
+
+\subsubsection{SEQUENCE Encoding}
+To encode a sequence a \textbf{ltc\_asn1\_list} array must be initialized with the members of the sequence and their respective pointers.  The encoding is performed
+with the following function.
+
+\index{der\_encode\_sequence()}
+\begin{verbatim}
+int der_encode_sequence(ltc_asn1_list *list, 
+                        unsigned long  inlen,
+                        unsigned char *out,  
+                        unsigned long *outlen);
+\end{verbatim}
+This encodes a sequence of items pointed to by \textit{list} where the list has \textit{inlen} items in it.  The SEQUENCE will be encoded to \textit{out} and of length \textit{outlen}.  The
+function will terminate when it reads all the items out of the list (upto \textit{inlen}) or it encounters an item in the list with a type of \textbf{LTC\_ASN1\_EOL}.
+
+The \textit{data} pointer in the list would be the same pointer you would pass to the respective ASN.1 encoder (e.g. der\_encode\_bit\_string()) and it is simply passed on
+verbatim to the dependent encoder.  The list can contain other SEQUENCE or SET types which enables you to have nested SEQUENCE and SET definitions.  In these cases
+the \textit{data} pointer is simply a pointer to another \textbf{ltc\_asn1\_list}.
+
+\subsubsection{SEQUENCE Decoding}
+
+\index{der\_decode\_sequence()}
+
+Decoding a SEQUENCE is similar to encoding.  You set up an array of \textbf{ltc\_asn1\_list} where in this case the \textit{size} member is the maximum size 
+(in certain cases).  For types such as IA5 STRING, BIT STRING, OCTET STRING (etc) the \textit{size} field is updated after successful decoding to reflect how many
+units of the respective type has been loaded.  
+
+\begin{verbatim}
+int der_decode_sequence(const unsigned char *in,
+                              unsigned long  inlen,
+                              ltc_asn1_list *list, 
+                              unsigned long  outlen);
+\end{verbatim}
+
+This will decode upto \textit{outlen} items from the input buffer \textit{in} of length \textit{inlen} octets.  The function will stop (gracefully) when it runs out of items to decode.
+It will fail (for among other reasons) when it runs out of input bytes to read, a data type is invalid or a heap failure occurred.
+
+For the following types the \textit{size} field will be updated to reflect the number of units read of the given type.
+\begin{enumerate}
+   \item BIT STRING
+   \item OCTET STRING
+   \item OBJECT IDENTIFIER
+   \item IA5 STRING
+   \item PRINTABLE STRING
+\end{enumerate}
+
+\subsubsection{SEQUENCE Length}
+
+The length of a SEQUENCE can be determined with the following function.
+
+\index{der\_length\_sequence()}
+\begin{verbatim}
+int der_length_sequence(ltc_asn1_list *list, 
+                        unsigned long  inlen,
+                        unsigned long *outlen);
+\end{verbatim}
+
+This will get the encoding size for the given \textit{list} of length \textit{inlen} and store it in \textit{outlen}.  
+
+\subsubsection{SEQUENCE Multiple Argument Lists}
+
+For small or simple sequences an encoding or decoding can be performed with one of the following two functions.
+
+\index{der\_encode\_sequence\_multi()}
+\index{der\_decode\_sequence\_multi()}
+
+\begin{verbatim}
+int der_encode_sequence_multi(unsigned char *out, 
+                              unsigned long *outlen, ...);
+
+int der_decode_sequence_multi(const unsigned char *in, 
+                                    unsigned long  inlen, ...);
+\end{verbatim}
+
+These either encode or decode (respectively) a SEQUENCE data type where the items in the sequence are specified after the length parameter.
+
+The list of items are specified as a triple of the form \textit{(type, size, data)}  where \textit{type} is an \textbf{int}, \textit{size} is a \textbf{unsigned long}
+and \textit{data} is \textbf{void} pointer.  The list of items must be terminated with an item with the type \textbf{LTC\_ASN1\_EOL}.
+
+It is ideal that you cast the \textit{size} values to unsigned long to ensure that the proper data type is passed to the function.  Constants such as \textit{1} without
+a cast or prototype are of type \textbf{int} by default.  Appending \textit{UL} or pre-pending \textit{(unsigned long)} is enough to cast it to the correct type.
+
+\begin{small}
+\begin{verbatim}
+unsigned char buf[MAXBUFSIZE];
+unsigned long buflen;
+int           err;
+
+   buflen = sizeof(buf);
+   if ((err = 
+        der_encode_sequence_multi(buf, &buflen,
+        LTC_ASN1_IA5_STRING, 5UL, "Hello",
+        LTC_ASN1_IA5_STRING, 7UL, " World!",
+        LTC_ASN1_EOL,        0UL, NULL)) != CRYPT_OK) {
+      // error handling
+   }
+\end{verbatim}
+\end{small}
+
+This example encodes a SEQUENCE with two IA5 STRING types containing ``Hello'' and `` World!'' respectively.  Note the usage of the \textbf{UL} modifier
+on the size parameters.  This forces the compiler to pass the numbers as the required \textbf{unsigned long} type that the function expects.
+
+\subsection{SET and SET OF}
+
+\index{SET} \index{SET OF}
+SET and SET OF are related to the SEQUENCE type in that they can be pretty much be decoded with the same code.  However, they are different, and they should
+be carefully noted.  The SET type is an unordered array of ASN.1 types sorted by the TAG (type identifier), whereas the SET OF type is an ordered array of 
+a \textbf{single} ASN.1 object sorted in ascending order by the DER their respective encodings.
+
+\subsubsection{SET Encoding}
+
+SETs use the same array structure of ltc\_asn1\_list that the SEQUENCE functions use.  They are encoded with the following function:
+
+\index{der\_encode\_set()}
+\begin{verbatim}
+int der_encode_set(ltc_asn1_list *list, 
+                   unsigned long  inlen,
+                   unsigned char *out,  
+                   unsigned long *outlen);
+\end{verbatim}            
+
+This will encode the list of ASN.1 objects in \textit{list} of length \textit{inlen} objects, and store the output in \textit{out} of length \textit{outlen} bytes.  
+The function will make a copy of the list provided, and sort it by the TAG.  Objects with identical TAGs are additionally sorted on their original placement in the 
+array (to make the process deterministic).
+
+This function will \textbf{NOT} recognize \textit{DEFAULT} objects, and it is the responsibility of the caller to remove them as required.
+
+\subsubsection{SET Decoding}
+
+The SET type can be decoded with the following function.
+
+\index{der\_decode\_set()}
+\begin{verbatim}
+int der_decode_set(const unsigned char *in, 
+                         unsigned long  inlen,
+                         ltc_asn1_list *list, 
+                         unsigned long  outlen);
+\end{verbatim}
+
+This will decode the SET specified by \textit{list} of length \textit{outlen} objects from the input buffer \textit{in} of length \textit{inlen} octets.
+
+It handles the fact that SETs are not strictly ordered and will make multiple passes (as required) through the list to decode all the objects.  
+
+\subsubsection{SET Length}
+The length of a SET can be determined by calling der\_length\_sequence() since they have the same encoding length.
+
+\subsubsection{SET OF Encoding}
+A \textit{SET OF} object is an array of identical objects (e.g. OCTET STRING) sorted in ascending order by the DER encoding of the object.  They are 
+used to store objects deterministically based solely on their encoding.  It uses the same array structure of ltc\_asn1\_list that the SEQUENCE functions
+use.  They are encoded with the following function.
+
+\index{der\_encode\_setof()}
+\begin{verbatim}
+int der_encode_setof(ltc_asn1_list *list, 
+                     unsigned long  inlen,
+                     unsigned char *out,  
+                     unsigned long *outlen);
+\end{verbatim}
+
+This will encode a \textit{SET OF} containing the \textit{list} of \textit{inlen} ASN.1 objects and store the encoding in the output buffer \textit{out} of length \textit{outlen}.
+
+The routine will first encode the SET OF in an unordered fashion (in a temporary buffer) then sort using the XQSORT macro and copy back to the output buffer.  This
+means you need at least enough memory to keep an additional copy of the output on the heap.  
+
+\subsubsection{SET OF Decoding}
+Since the decoding of a \textit{SET OF} object is unambiguous it can be decoded with der\_decode\_sequence().  
+
+\subsubsection{SET OF Length}
+Like the SET type the der\_length\_sequence() function can be used to determine the length of a \textit{SET OF} object.
+
+\subsection{ASN.1 INTEGER}
+
+To encode or decode INTEGER data types use the following functions.
+
+\index{der\_encode\_integer()}\index{der\_decode\_integer()}\index{der\_length\_integer()}
+\begin{verbatim}
+int der_encode_integer(         void *num, 
+                       unsigned char *out, 
+                       unsigned long *outlen);
+
+int der_decode_integer(const unsigned char *in, 
+                             unsigned long  inlen, 
+                                      void *num);
+
+int der_length_integer(         void *num, 
+                       unsigned long *len);
+\end{verbatim}
+
+These will encode or decode a signed INTEGER data type using the bignum data type to store the large INTEGER.  To encode smaller values without allocating
+a bignum to store the value, the \textit{short} INTEGER functions were made available.
+
+\index{der\_encode\_short\_integer()}\index{der\_decode\_short\_integer()}\index{der\_length\_short\_integer()}
+\begin{verbatim}
+int der_encode_short_integer(unsigned long  num, 
+                             unsigned char *out, 
+                             unsigned long *outlen);
+
+int der_decode_short_integer(const unsigned char *in,  
+                                   unsigned long  inlen, 
+                                   unsigned long *num);
+
+int der_length_short_integer(unsigned long  num, 
+                             unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an unsigned \textbf{unsigned long} type (only reads upto 32--bits).  For values in the range $0 \dots 2^{32} - 1$ the integer 
+and short integer functions can encode and decode each others outputs.  
+
+\subsection{ASN.1 BIT STRING}
+
+\index{der\_encode\_bit\_string()}\index{der\_decode\_bit\_string()}\index{der\_length\_bit\_string()}
+\begin{verbatim}
+int der_encode_bit_string(const unsigned char *in,

+                                unsigned char *out, 
+                                unsigned long *outlen);

+
+int der_length_bit_string(unsigned long  nbits, 
+                          unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode a BIT STRING data type.  The bits are passed in (or read out) using one \textbf{char} per bit.  A non--zero value will be interpreted
+as a one bit, and a zero value a zero bit.
+
+\subsection{ASN.1 OCTET STRING}
+
+\index{der\_encode\_octet\_string()}\index{der\_decode\_octet\_string()}\index{der\_length\_octet\_string()}

+                            unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an OCTET STRING data type.  The octets are stored using one \textbf{unsigned char} each.

+\subsection{ASN.1 OBJECT IDENTIFIER}
+
+\index{der\_encode\_object\_identifier()}\index{der\_decode\_object\_identifier()}\index{der\_length\_object\_identifier()}

+\end{verbatim}
+
+These will encode or decode an OBJECT IDENTIFIER object.  The words of the OID are stored in individual \textbf{unsigned long} elements, and must be in the range
+$0 \ldots 2^{32} - 1$.  
+
+\subsection{ASN.1 IA5 STRING}

+                                unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an IA5 STRING.  The characters are read or stored in individual \textbf{char} elements.  These functions performs internal character
+to numerical conversions based on the conventions of the compiler being used.  For instance, on an x86\_32 machine 'A' == 65 but the same may not be true on 
+say a SPARC machine.  Internally, these functions have a table of literal characters and their numerical ASCII values.  This provides a stable conversion provided
+that the build platform honours the run--time platforms character conventions.

+                           unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an UTF8 STRING.  The characters are read or stored in individual \textbf{wchar\_t} elements.  These function performs no internal
+mapping and treat the characters as literals.  
+
+These functions use the \textbf{wchar\_t} type which is not universally available.  In those cases, the library will typedef it to \textbf{unsigned long}.  If you 
+intend to use the ISO C functions for working with wide--char arrays, you should make sure that wchar\_t has been defined previously.
+
+\subsection{ASN.1 UTCTIME}
+
+The UTCTIME type is to store a date and time in ASN.1 format.  It uses the following structure to organize the time.
+
+\index{ltc\_utctime structure}
+\begin{verbatim}
+typedef struct {
+   unsigned YY, /* year    00--99 */
+            MM, /* month   01--12 */
+            DD, /* day     01--31 */
+            hh, /* hour    00--23 */
+            mm, /* minute  00--59 */
+            ss, /* second  00--59 */
+            off_dir, /* timezone offset direction 0 == +, 1 == - */
+            off_hh, /* timezone offset hours */
+            off_mm; /* timezone offset minutes */
+} ltc_utctime;
+\end{verbatim}
+
+The time can be offset plus or minus a set amount of hours (off\_hh) and minutes (off\_mm).  When \textit{off\_dir} is zero, the time will be added otherwise it 
+will be subtracted.  For instance, the array $\lbrace 5, 6, 20, 22, 4, 00, 0, 5, 0 \rbrace$ represents the current time of 
+\textit{2005, June 20th, 22:04:00} with a time offset of +05h00.  
+
+\index{der\_encode\_utctime()}\index{der\_decode\_utctime()}\index{der\_length\_utctime()}
+\begin{verbatim}
+int der_encode_utctime(  ltc_utctime *utctime, 
+                       unsigned char *out,   
+                       unsigned long *outlen);
+
+int der_decode_utctime(const unsigned char *in, 
+                             unsigned long *inlen,
+                               ltc_utctime *out);
+
+int der_length_utctime(  ltc_utctime *utctime, 
+                       unsigned long *outlen);
+\end{verbatim}
+
+The encoder will store time in one of the two ASN.1 formats, either \textit{YYMMDDhhmmssZ} or \textit{YYMMDDhhmmss$\pm$hhmm}, and perform minimal error checking on the 
+input.  The decoder will read all valid ASN.1 formats and perform range checking on the values (not complete but rational) useful for catching packet errors.
+
+It is suggested that decoded data be further scrutinized (e.g. days of month in particular).
+
+\subsection{ASN.1 CHOICE}
+
+The CHOICE ASN.1 type represents a union of ASN.1 types all of which are stored in a \textit{ltc\_asn1\_list}.  There is no encoder for the CHOICE type, only a 
+decoder.  The decoder will scan through the provided list attempting to use the appropriate decoder on the input packet.  The list can contain any ASN.1 data
+type\footnote{Except it cannot have LTC\_ASN1\_INTEGER and LTC\_ASN1\_SHORT\_INTEGER simultaneously.} except for other CHOICE types.  
+
+There is no encoder for the CHOICE type as the actual DER encoding is the encoding of the chosen type.  
+
+\index{der\_decode\_choice()}
+\begin{verbatim}
+int der_decode_choice(const unsigned char *in, 
+                            unsigned long *inlen,
+                            ltc_asn1_list *list, 
+                            unsigned long  outlen);
+\end{verbatim}
+
+This will decode the input in the \textit{in} field of length \textit{inlen}.  It uses the provided ASN.1 list specified in the \textit{list} field which has 
+\textit{outlen} elements.  The \textit{inlen} field will be updated with the length of the decoded data type, as well as the respective entry in the \textit{list} field 
+will have the \textit{used} flag set to non--zero to reflect it was the data type decoded.
+
+\subsection{ASN.1 Flexi Decoder}
+The ASN.1 \textit{flexi} decoder allows the developer to decode arbitrary ASN.1 DER packets (provided they use data types LibTomCrypt supports) without first knowing
+the structure of the data.  Where der\_decode \_sequence() requires the developer to specify the data types to decode in advance the flexi decoder is entirely
+free form.
+
+The flexi decoder uses the same \textit{ltc\_asn1\_list} but instead of being stored in an array it uses the linked list pointers \textit{prev}, \textit{next}, \textit{parent} 
+and \textit{child}.  The list works as a \textit{doubly-linked list} structure where decoded items at the same level are siblings (using next and prev) and items
+encoded in a SEQUENCE are stored as a child element.
+
+When a SEQUENCE or SET has been encountered a SEQUENCE (or SET resp.) item will be added as a sibling (e.g. list.type == LTC\_ASN1\_SEQUENCE) and the child 
+pointer points to a new list of items contained within the object.
+
+\index{der\_decode\_sequence\_flexi()}
+\begin{verbatim}
+int  der_decode_sequence_flexi(const unsigned char *in, 
+                                     unsigned long *inlen, 
+                                    ltc_asn1_list **out);
+\end{verbatim}
+
+This will decode items in the \textit{in} buffer of max input length \textit{inlen} and store the newly created pointer to the list in \textit{out}.  This function allocates
+all required memory for the decoding.  It stores the number of octets read back into \textit{inlen}.
+
+The function will terminate when either it hits an invalid ASN.1 tag, or it reads \textit{inlen} octets.  An early termination is a soft error, and returns
+normally.  The decoded list \textit{out} will point to the very first element of the list (e.g. both parent and prev pointers will be \textbf{NULL}).  
+
+An invalid decoding will terminate the process, and free the allocated memory automatically.  
+
+\textbf{Note:} the list decoded by this function is \textbf{NOT} in the correct form for der\_encode\_sequence() to use directly.  You will have to first 
+have to convert the list by first storing all of the siblings in an array then storing all the children as sub-lists of a sequence using the \textit{.data} 
+pointer.  Currently no function in LibTomCrypt provides this ability.
+
+\subsubsection{Sample Decoding}
+Suppose we decode the following structure:
+\begin{small}
+\begin{verbatim}
+User ::= SEQUENCE {
+   Name        IA5 STRING
+   LoginToken  SEQUENCE {
+      passwdHash   OCTET STRING
+      pubkey       ECCPublicKey
+   }
+   LastOn      UTCTIME
+}
+\end{verbatim}
+\end{small}
+\begin{flushleft}and we decoded it with the following code:\end{flushleft}
+
+\begin{small}
+\begin{verbatim}
+unsigned char inbuf[MAXSIZE];
+unsigned long inbuflen;
+ltc_asn1_list *list;
+int           err;
+
+/* somehow fill inbuf/inbuflen */
+if ((err = der_decode_sequence_flexi(inbuf, inbuflen, &list)) != CRYPT_OK) {
+   printf("Error decoding: %s\n", error_to_string(err));
+   exit(EXIT_FAILURE);
+}
+\end{verbatim}
+\end{small}
+
+At this point \textit{list} would point to the SEQUENCE identified by \textit{User}.  It would have no sibblings (prev or next), and only a child node.  Walking to the child
+node with the following code will bring us to the \textit{Name} portion of the SEQUENCE:
+\begin{small}
+\begin{verbatim}
+list = list->child;
+\end{verbatim}
+\end{small}
+Now \textit{list} points to the \textit{Name} member (with the tag IA5 STRING).  The \textit{data}, \textit{size}, and \textit{type} members of \textit{list} should reflect
+that of an IA5 STRING.  The sibbling will now be the \textit{LoginToken} SEQUENCE.  The sibbling has a child node which points to the \textit{passwdHash} OCTET STRING.
+We can walk to this node with the following code:
+\begin{small}
+\begin{verbatim}
+/* list already pointing to 'Name' */
+list = list->next->child;
+\end{verbatim}
+\end{small}
+At this point, \textit{list} will point to the \textit{passwdHash} member of the innermost SEQUENCE.  This node has a sibbling, the \textit{pubkey} member of the SEQUENCE.
+The \textit{LastOn} member of the SEQUENCE is a sibbling of the LoginToken node, if we wanted to walk there we would have to go up and over via:
+\begin{small}
+\begin{verbatim}
+list = list->parent->next;
+\end{verbatim}
+\end{small}
+At this point, we are pointing to the last node of the list.  Lists are terminated in all directions by a \textbf{NULL} pointer.  All nodes are doubly linked so that you 
+can walk up and down the nodes without keeping pointers lying around.
+
+
+
+
+
+\subsubsection{Free'ing a Flexi List}
+To free the list use the following function.
+
+\index{der\_sequence\_free()}
+\begin{verbatim}
+void der_sequence_free(ltc_asn1_list *in);
+\end{verbatim}
+
+This will free all of the memory allocated by der\_decode\_sequence\_flexi().
+
+\mysection{Password Based Cryptography}
+\subsection{PKCS \#5}
+\index{PKCS \#5}
+In order to securely handle user passwords for the purposes of creating session keys and chaining IVs the PKCS \#5 was drafted.   PKCS \#5
+is made up of two algorithms, Algorithm One and Algorithm Two.  Algorithm One is the older fairly limited algorithm which has been implemented
+for completeness.  Algorithm Two is a bit more modern and more flexible to work with.
+
+\subsection{Algorithm One}
+Algorithm One accepts as input a password, an 8--byte salt, and an iteration counter.  The iteration counter is meant to act as delay for
+people trying to brute force guess the password.  The higher the iteration counter the longer the delay.  This algorithm also requires a hash 
+algorithm and produces an output no longer than the output of the hash.  
+
+\index{pkcs\_5\_alg1()}
+\begin{alltt}
+int pkcs_5_alg1(const unsigned char *password, 
+                      unsigned long  password_len, 
+                const unsigned char *salt, 
+                                int  iteration_count,  
+                                int  hash_idx,
+                      unsigned char *out,
+                      unsigned long *outlen)
+\end{alltt}
+Where \textit{password} is the user's password.  Since the algorithm allows binary passwords you must also specify the length in \textit{password\_len}.  
+The \textit{salt} is a fixed size 8--byte array which should be random for each user and session.  The \textit{iteration\_count} is the delay desired
+on the password.  The \textit{hash\_idx} is the index of the hash you wish to use in the descriptor table.  
+
+The output of length up to \textit{outlen} is stored in \textit{out}.  If \textit{outlen} is initially larger than the size of the hash functions output
+it is set to the number of bytes stored.  If it is smaller than not all of the hash output is stored in \textit{out}.
+
+\subsection{Algorithm Two}
+
+Algorithm Two is the recommended algorithm for this task.  It allows variable length salts, and can produce outputs larger than the 
+hash functions output.  As such, it can easily be used to derive session keys for ciphers and MACs as well initial vectors as required
+from a single password and invocation of this algorithm.
+
+\index{pkcs\_5\_alg2()}
+\begin{alltt}
+int pkcs_5_alg2(const unsigned char *password,
+                      unsigned long  password_len,

+                      unsigned long  salt_len,
+                                int  iteration_count, 
+                                int  hash_idx,
+                      unsigned char *out,
+                      unsigned long *outlen)
+\end{alltt}
+Where \textit{password} is the users password.  Since the algorithm allows binary passwords you must also specify the length in \textit{password\_len}.  
+The \textit{salt} is an array of size \textit{salt\_len}.  It should be random for each user and session.  The \textit{iteration\_count} is the delay desired
+on the password.  The \textit{hash\_idx} is the index of the hash you wish to use in the descriptor table.   The output of length up to 
+\textit{outlen} is stored in \textit{out}.
+
+\begin{verbatim}

+}
+\end{verbatim}
+
+\chapter{Miscellaneous}
+\mysection{Base64 Encoding and Decoding}
+The library provides functions to encode and decode a RFC 1521 base--64 coding scheme.  The characters used in the mappings are:
+\begin{verbatim}
+ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/
+\end{verbatim}
+Those characters are supported in the 7-bit ASCII map, which means they can be used for transport over
+common e-mail, usenet and HTTP mediums.  The format of an encoded stream is just a literal sequence of ASCII characters
+where a group of four represent 24-bits of input.  The first four chars of the encoders output is the length of the 
+original input.  After the first four characters is the rest of the message.
+
+Often, it is desirable to line wrap the output to fit nicely in an e-mail or usenet posting.  The decoder allows you to
+put any character (that is not in the above sequence) in between any character of the encoders output.  You may not however,
+break up the first four characters.
+
+To encode a binary string in base64 call:
+\index{base64\_encode()}  \index{base64\_decode()} 
+\begin{verbatim}
+int base64_encode(const unsigned char *in, 
+                        unsigned long  len, 
+                        unsigned char *out, 
+                        unsigned long *outlen);
+\end{verbatim}
+Where \textit{in} is the binary string and \textit{out} is where the ASCII output is placed.  You must set the value of \textit{outlen} prior
+to calling this function and it sets the length of the base64 output in \textit{outlen} when it is done.  To decode a base64 
+string call:
+\begin{verbatim}
+int base64_decode(const unsigned char *in, 
+                        unsigned long  len, 
+                        unsigned char *out, 
+                        unsigned long *outlen);
+\end{verbatim}
+
+\mysection{Primality Testing}
+\index{Primality Testing}
+The library includes primality testing and random prime functions as well.  The primality tester will perform the test in
+two phases.  First it will perform trial division by the first few primes.  Second it will perform eight rounds of the 
+Rabin-Miller primality testing algorithm.  If the candidate passes both phases it is declared prime otherwise it is declared
+composite.  No prime number will fail the two phases but composites can.  Each round of the Rabin-Miller algorithm reduces
+the probability of a pseudo-prime by $1 \over 4$ therefore after sixteen rounds the probability is no more than 
+$\left ( { 1 \over 4 } \right )^{8} = 2^{-16}$.  In practice the probability of error is in fact much lower than that.
+
+When making random primes the trial division step is in fact an optimized implementation of \textit{Implementation of Fast RSA Key Generation on Smart Cards}\footnote{Chenghuai Lu, Andre L. M. dos Santos and Francisco R. Pimentel}.
+In essence a table of machine-word sized residues are kept of a candidate modulo a set of primes.  When the candidate
+is rejected and ultimately incremented to test the next number the residues are updated without using multi-word precision
+math operations.  As a result the routine can scan ahead to the next number required for testing with very little work
+involved.
+
+In the event that a composite did make it through it would most likely cause the the algorithm trying to use it to fail.  For 
+instance, in RSA two primes $p$ and $q$ are required.  The order of the multiplicative sub-group (modulo $pq$) is given 
+as $\phi(pq)$ or $(p - 1)(q - 1)$.  The decryption exponent $d$ is found as $de \equiv 1\mbox{ }(\mbox{mod } \phi(pq))$.  If either $p$ or $q$ is composite the value of $d$ will be incorrect and the user
+will not be able to sign or decrypt messages at all.  Suppose $p$ was prime and $q$ was composite this is just a variation of 
+the multi-prime RSA.  Suppose $q = rs$ for two primes $r$ and $s$ then $\phi(pq) = (p - 1)(r - 1)(s - 1)$ which clearly is 
+not equal to $(p - 1)(rs - 1)$.
+
+These are not technically part of the LibTomMath library but this is the best place to document them.  
+To test if a \textit{mp\_int} is prime call:
+\begin{verbatim}
+int is_prime(mp_int *N, int *result);
+\end{verbatim}
+This puts a one in \textit{result} if the number is probably prime, otherwise it places a zero in it.  It is assumed that if 
+it returns an error that the value in \textit{result} is undefined.  To make 
+a random prime call:
+\begin{verbatim}
+int rand_prime(       mp_int *N, 
+               unsigned long len, 
+                  prng_state *prng, 
+                         int  wprng);
+\end{verbatim}
+Where \textit{len} is the size of the prime in bytes ($2 \le len \le 256$).  You can set \textit{len} to the negative size you want
+to get a prime of the form $p \equiv 3\mbox{ }(\mbox{mod } 4)$.  So if you want a 1024-bit prime of this sort pass 
+\textit{len = -128} to the function.  Upon success it will return {\bf CRYPT\_OK} and \textit{N} will contain an integer which
+is very likely prime.
+
+\chapter{Programming Guidelines}
+
+\mysection{Secure Pseudo Random Number Generators}
+Probably the single most vulnerable point of any cryptosystem is the PRNG.  Without one, generating and protecting secrets
+would be impossible.  The requirement that one be setup correctly is vitally important, and to address this point the library
+does provide two RNG sources that will address the largest amount of end users as possible.  The \textit{sprng} PRNG provides an easy to 
+access source of entropy for any application on a UNIX (and the like) or Windows computer.  
+
+However, when the end user is not on one of these platforms, the application developer must address the issue of finding
+entropy.  This manual is not designed to be a text on cryptography.  I would just like to highlight that when you design
+a cryptosystem make sure the first problem you solve is getting a fresh source of entropy.  
+
+\mysection{Preventing Trivial Errors}
+Two simple ways to prevent trivial errors is to prevent overflows, and to check the return values.  All of the functions
+which output variable length strings will require you to pass the length of the destination.  If the size of your output
+buffer is smaller than the output it will report an error.  Therefore, make sure the size you pass is correct!
+
+Also, virtually all of the functions return an error code or {\bf CRYPT\_OK}.  You should detect all errors, as simple 
+typos can cause algorithms to fail to work as desired.
+
+\mysection{Registering Your Algorithms}
+To avoid linking and other run--time errors it is important to register the ciphers, hashes and PRNGs you intend to use 
+before you try to use them.  This includes any function which would use an algorithm indirectly through a descriptor table.
+
+A neat bonus to the registry system is that you can add external algorithms that are not part of the library without 
+having to hack the library.  For example, suppose you have a hardware specific PRNG on your system.  You could easily 
+write the few functions required plus a descriptor.  After registering your PRNG, all of the library functions that 
+need a PRNG can instantly take advantage of it.  The same applies for ciphers, hashes, and bignum math routines.
+
+\mysection{Key Sizes}
+
+\subsection{Symmetric Ciphers}
+For symmetric ciphers, use as large as of a key as possible.  For the most part \textit{bits are cheap} so using a 256--bit key
+is not a hard thing to do.  As a good rule of thumb do not use a key smaller than 128 bits.
+
+\subsection{Asymmetric Ciphers}
+The following chart gives the work factor for solving a DH/RSA public key using the NFS.  The work factor for a key of order
+$n$ is estimated to be
+\begin{equation}
+e^{1.923 \cdot ln(n)^{1 \over 3} \cdot ln(ln(n))^{2 \over 3}} 
+\end{equation}
+
+Note that $n$ is not the bit-length but the magnitude.  For example, for a 1024-bit key $n = 2^{1024}$.  The work required 
+is:
+\begin{figure}[here]
+\begin{center}
+\begin{tabular}{|c|c|}
+    \hline RSA/DH Key Size (bits) & Work Factor ($log_2$) \\
+    \hline 512 & 63.92 \\
+    \hline 768 & 76.50 \\
+    \hline 1024 & 86.76 \\
+    \hline 1536 & 103.37 \\
+    \hline 2048 & 116.88 \\
+    \hline 2560 & 128.47 \\
+    \hline 3072 & 138.73 \\
+    \hline 4096 & 156.49 \\
+    \hline 
+\end{tabular}
+\end{center}
+\caption{RSA/DH Key Strength}
+\end{figure}
+
+The work factor for ECC keys is much higher since the best attack is still fully exponential.  Given a key of magnitude
+$n$ it requires $\sqrt n$ work.  The following table summarizes the work required:
+\begin{figure}[here]
+\begin{center}
+\begin{tabular}{|c|c|}
+    \hline ECC Key Size (bits) & Work Factor ($log_2$) \\
+    \hline 112 & 56 \\
+    \hline 128 & 64 \\
+    \hline 160 & 80 \\
+    \hline 192 & 96  \\
+    \hline 224 & 112 \\
+    \hline 256 & 128 \\
+    \hline 384 & 192 \\
+    \hline 521 & 260.5 \\
+    \hline
+\end{tabular}
+\end{center}
+\caption{ECC Key Strength}
+\end{figure}
+
+Using the above tables the following suggestions for key sizes seems appropriate:
+\begin{center}
+\begin{tabular}{|c|c|c|}
+    \hline Security Goal & RSA/DH Key Size (bits) & ECC Key Size (bits) \\
+    \hline Near term   & 1024 & 160 \\
+    \hline Short term  & 1536 & 192 \\
+    \hline Long Term   & 2560 & 384 \\
+    \hline 
+\end{tabular}
+\end{center}
+
+\mysection{Thread Safety}
+The library is not fully thread safe but several simple precautions can be taken to avoid any problems.  The registry functions
+such as register\_cipher() are not thread safe no matter what you do.  It is best to call them from your programs initialization
+code before threads are initiated.
+
+The rest of the code uses state variables you must pass it such as hash\_state, hmac\_state, etc.  This means that if each
+thread has its own state variables then they will not affect each other, and are fully thread safe.  This is fairly simple with symmetric ciphers
+and hashes.  
+
+\index{LTC\_PTHREAD}
+The only sticky issue is a shared PRNG which can be alleviated with the careful use of mutex devices.  Defining LTC\_PTHREAD for instance, enables
+pthreads based mutex locking in various routines such as the Yarrow and Fortuna PRNGs, the fixed point ECC multiplier, and other routines.
+
+\chapter{Configuring and Building the Library}
+\mysection{Introduction}
+The library is fairly flexible about how it can be built, used, and generally distributed.  Additions are being made with
+each new release that will make the library even more flexible.  Each of the classes of functions can be disabled during
+the build process to make a smaller library.  This is particularly useful for shared libraries.
+
+As of v1.06 of the library, the build process has been moved to two steps for the typical LibTomCrypt application.  This is because
+LibTomCrypt no longer provides a math API on its own and relies on third party libraries (such as LibTomMath, GnuMP, or TomsFastMath).
+
+The build process now consists of installing a math library first, and then building and installing LibTomCrypt with a math library
+configured.  Note that LibTomCrypt can be built with no internal math descriptors.  This means that one must be provided at either
+build, or run time for the application.  LibTomCrypt comes with three math descriptors that provide a standard interface to math 
+libraries.
+
+\mysection{Makefile variables}
+
+All GNU driven makefiles (including the makefile for ICC) use a set of common variables to control the build and install process.  Most of the 
+settings can be overwritten from the command line which makes custom installation a breeze.
+
+\index{MAKE}\index{CC}\index{AR}
+\subsection{MAKE, CC and AR}
+The MAKE, CC and AR flags can all be overwritten.  They default to \textit{make}, \textit{\$CC} and \textit{\$AR} respectively.  
+Changing MAKE allows you to change what program will be invoked to handle sub--directories. For example, this
+
+\begin{verbatim}
+MAKE=gmake gmake install
+\end{verbatim}
+
+\begin{flushleft} will build and install the libraries with the \textit{gmake} tool.  Similarly, \end{flushleft}
+
+\begin{verbatim}
+CC=arm-gcc AR=arm-ar make 
+\end{verbatim}
+
+\begin{flushleft} will build the library using \textit{arm--gcc} as the compiler and \textit{arm--ar} as the archiver. \end{flushleft}
+
+\subsection{IGNORE\_SPEED}
+\index{IGNORE\_SPEED}
+When \textbf{IGNORE\_SPEED} has been defined the default optimization flags for CFLAGS will be disabled which allows the developer to specify new
+CFLAGS on the command line.  E.g. to add debugging
+
+\begin{verbatim}
+CFLAGS="-g3" make IGNORE_SPEED=1
+\end{verbatim}
+
+This will turn off optimizations and add \textit{-g3} to the CFLAGS which enables debugging.  
+
+\subsection{LIBNAME and LIBNAME\_S}
+\index{LIBNAME} \index{LIBNAME\_S}
+\textbf{LIBNAME} is the name of the output library (archive) to create.  It defaults to \textit{libtomcrypt.a} for static builds and \textit{libtomcrypt.la} for
+shared.  The \textbf{LIBNAME\_S} variable is the static name while doing shared builds.  Ideally they should have the same prefix but don't have to.
+
+\index{LIBTEST} \index{LIBTEST\_S}
+Similarly \textbf{LIBTEST} and \textbf{LIBTEST\_S} are the names for the profiling and testing library.  The default is \textit{libtomcrypt\_prof.a} for 
+static and \textit{libtomcrypt\_prof.la} for shared.
+
+\subsection{Installation Directories}
+\index{DESTDIR} \index{LIBPATH} \index{INCPATH} \index{DATADIR}
+\textbf{DESTDIR} is the prefix for the installation directories.  It defaults to an empty string.  \textbf{LIBPATH} is the prefix for the library
+directory which defaults to \textit{/usr/lib}.  \textbf{INCPATH} is the prefix for the header file directory which defaults to \textit{/usr/include}.  
+\textbf{DATADIR} is the prefix for the data (documentation) directory which defaults to \textit{/usr/share/doc/libtomcrypt/pdf}.
+
+All four can be used to create custom install locations depending on the nature of the OS and file system in use.
+
+\begin{verbatim}
+make LIBPATH=/home/tom/project/lib INCPATH=/home/tom/project/include \
+     DATAPATH=/home/tom/project/docs install
+\end{verbatim}
+
+This will build the library and install it to the directories under \textit{/home/tom/project/}.  e.g.
+
+\begin{small}
+\begin{verbatim}
+/home/tom/project/:
+total 1

+\mysection{Extra libraries}
+\index{EXTRALIBS}
+\textbf{EXTRALIBS} specifies any extra libraries required to link the test programs and shared libraries.  They are specified in the notation
+that GCC expects for global archives.
+
+\begin{verbatim}
+CFLAGS="-DTFM_DESC -DUSE_TFM" EXTRALIBS=-ltfm make install \
+                                                   test timing
+\end{verbatim}
+
+This will install the library using the TomsFastMath library and link the \textit{libtfm.a} library out of the default library search path.  The two
+defines are explained below.  You can specify multiple archives (say if you want to support two math libraries, or add on additional code) to 
+the \textbf{EXTRALIBS} variable by separating them by a space.
+
+Note that \textbf{EXTRALIBS} is not required if you are only making and installing the static library but none of the test programs.  
+
+\mysection{Building a Static Library}
+
+Building a static library is fairly trivial as it only requires one invocation of the GNU make command.  
+
+\begin{verbatim}
+CFLAGS="-DTFM_DESC" make install
+\end{verbatim}
+
+That will build LibTomCrypt (including the TomsFastMath descriptor), and install it in the default locations indicated previously.  You can enable 
+the built--in LibTomMath descriptor as well (or in place of the TomsFastMath descriptor).  Similarly, you can build the library with no built--in 
+math descriptors.  
+
+\begin{verbatim}
+make install
+\end{verbatim}
+
+In this case, no math descriptors are present in the library and they will have to be made available at build or run time before you can use any of the 
+public key functions.  
+
+Note that even if you include the built--in descriptors you must link against the source library as well.  
+
+\begin{verbatim}
+gcc -DTFM_DESC myprogram.c -ltomcrypt -ltfm -o myprogram
+\end{verbatim}
+
+This will compile \textit{myprogram} and link it against the LibTomCrypt library as well as TomsFastMath (which must have been previously installed).  Note that 
+we define \textbf{TFM\_DESC} for compilation.  This is so that the TFM descriptor symbol will be defined for the client application to make use of without 
+giving warnings.
+
+\mysection{Building a Shared Library}
+
+LibTomCrypt can also be built as a shared library through the \textit{makefile.shared} make script.  It is similar to use as the static script except
+that you \textbf{must} specify the \textbf{EXTRALIBS} variable at install time.  
+
+\begin{verbatim}
+CFLAGS="-DTFM_DESC" EXTRALIBS=-ltfm make -f makefile.shared install
+\end{verbatim}
+
+This will build and install the library and link the shared object against the TomsFastMath library (which must be installed as a shared object as well).  The 
+shared build process requires libtool to be installed.
+
+\mysection{Header Configuration}
+The file \textit{tomcrypt\_cfg.h} is what lets you control various high level macros which control the behaviour of the library.  Build options are also
+stored in \textit{tomcrypt\_custom.h} which allow the enabling and disabling of various algorithms.
+
+\subsubsection{ARGTYPE}
+This lets you control how the LTC\_ARGCHK macro will behave.  The macro is used to check pointers inside the functions against
+NULL.  There are four settings for ARGTYPE.  When set to 0, it will have the default behaviour of printing a message to 
+stderr and raising a SIGABRT signal.  This is provided so all platforms that use LibTomCrypt can have an error that functions
+similarly.  When set to 1, it will simply pass on to the assert() macro.  When set to 2, the macro will display the error to
+stderr then return execution to the caller.  This could lead to a segmentation fault (e.g. when a pointer is \textbf{NULL}) but is useful
+if you handle signals on your own.  When set to 3, it will resolve to a empty macro and no error checking will be performed.  Finally, when set
+to 4, it will return CRYPT\_INVALID\_ARG to the caller.  
+
+\subsubsection{Endianess}
+There are five macros related to endianess issues.  For little endian platforms define, \textbf{ENDIAN\_LITTLE}.  For big endian
+platforms define \textbf{ENDIAN\_BIG}.  Similarly when the default word size of an \textit{unsigned long} is 32-bits define \textbf{ENDIAN\_32BITWORD}
+or define \textbf{ENDIAN\_64BITWORD} when its 64-bits.  If you do not define any of them the library will automatically use \textbf{ENDIAN\_NEUTRAL}
+which will work on all platforms.
+
+Currently LibTomCrypt will detect x86-32, x86-64, MIPS R5900, SPARC and SPARC64 running GCC as well as x86-32 running MSVC.  
+
+\mysection{The Configure Script}
+There are also options you can specify from the \textit{tomcrypt\_custom.h} header file.
+
+\subsection{X memory routines}
+\index{XMALLOC}\index{XCALLOC}\index{XREALLOC}\index{XFREE}
+At the top of tomcrypt\_custom.h are a series of macros denoted as XMALLOC, XCALLOC, XREALLOC, XFREE, and so on.  They resolve to 
+the name of the respective functions from the standard C library by default.  This lets you substitute in your own memory routines.  
+If you substitute in your own functions they must behave like the standard C library functions in terms of what they expect as input and 
+output.
+
+These macros are handy for working with platforms which do not have a standard C library.  For instance, the OLPC\footnote{See http://dev.laptop.org/git?p=bios-crypto;a=summary}
+bios code uses these macros to redirect to very compact heap and string operations.
+
+\subsection{X clock routines}
+The rng\_get\_bytes() function can call a function that requires the clock() function.  These macros let you override
+the default clock() used with a replacement.  By default the standard C library clock() function is used.
+
+\subsection{LTC\_NO\_FILE}
+During the build if LTC\_NO\_FILE is defined then any function in the library that uses file I/O will not call the file I/O 
+functions and instead simply return CRYPT\_NOP.  This should help resolve any linker errors stemming from a lack of
+file I/O on embedded platforms.
+
+\subsection{LTC\_CLEAN\_STACK}
+When this functions is defined the functions that store key material on the stack will clean up afterwards.  
+Assumes that you have no memory paging with the stack.
+
+\subsection{LTC\_TEST}
+When this has been defined the various self--test functions (for ciphers, hashes, prngs, etc) are included in the build.  This is the default configuration.
+If LTC\_NO\_TEST has been defined, the testing routines will be compacted and only return CRYPT\_NOP.
+
+\subsection{LTC\_NO\_FAST}
+When this has been defined the library will not use faster word oriented operations.  By default, they are only enabled for platforms
+which can be auto-detected.  This macro ensures that they are never enabled.
+
+\subsection{LTC\_FAST}
+This mode (auto-detected with x86\_32,x86\_64 platforms with GCC or MSVC) configures various routines such as ctr\_encrypt() or 
+cbc\_encrypt() that it can safely XOR multiple octets in one step by using a larger data type.  This has the benefit of 
+cutting down the overhead of the respective functions.  
+
+This mode does have one downside.  It can cause unaligned reads from memory if you are not careful with the functions.  This is why
+it has been enabled by default only for the x86 class of processors where unaligned accesses are allowed.  Technically LTC\_FAST
+is not \textit{portable} since unaligned accesses are not covered by the ISO C specifications.
+
+In practice however, you can use it on pretty much any platform (even MIPS) with care.
+
+By design the \textit{fast} mode functions won't get unaligned on their own.  For instance, if you call ctr\_encrypt() right after calling
+ctr\_start() and all the inputs you gave are aligned than ctr\_encrypt() will perform aligned memory operations only.  However, if you 
+call ctr\_encrypt() with an odd amount of plaintext then call it again the CTR pad (the IV) will be partially used.  This will
+cause the ctr routine to first use up the remaining pad bytes.  Then if there are enough plaintext bytes left it will use 
+whole word XOR operations.  These operations will be unaligned.
+
+The simplest precaution is to make sure you process all data in power of two blocks and handle \textit{remainder} at the end.  e.g. If you are 
+CTR'ing a long stream process it in blocks of (say) four kilobytes and handle any remaining incomplete blocks at the end of the stream.  
+
+\index{LTC\_FAST\_TYPE}
+If you do plan on using the \textit{LTC\_FAST} mode you have to also define a \textit{LTC\_FAST\_TYPE} macro which resolves to an optimal sized
+data type you can perform integer operations with.  Ideally it should be four or eight bytes since it must properly divide the size 
+of your block cipher (e.g. 16 bytes for AES).  This means sadly if you're on a platform with 57--bit words (or something) you can't 
+use this mode.  So sad.
+
+\subsection{LTC\_NO\_ASM}
+When this has been defined the library will not use any inline assembler.  Only a few platforms support assembler inlines but various versions of ICC and GCC
+cannot handle all of the assembler functions.  
+
+\subsection{Symmetric Ciphers, One-way Hashes, PRNGS and Public Key Functions}
+There are a plethora of macros for the ciphers, hashes, PRNGs and public key functions which are fairly 
+self-explanatory.  When they are defined the functionality is included otherwise it is not.  There are some 
+dependency issues which are noted in the file.  For instance, Yarrow requires CTR chaining mode, a block 
+cipher and a hash function.
+
+Also see technical note number five for more details.
+
+\subsection{LTC\_EASY}
+When defined the library is configured to build fewer algorithms and modes.  Mostly it sticks to NIST and ANSI approved algorithms.  See 
+the header file \textit{tomcrypt\_custom.h} for more details.  It is meant to provide literally an easy method of trimming the library 
+build to the most minimum of useful functionality.
+
+\subsection{TWOFISH\_SMALL and TWOFISH\_TABLES}
+Twofish is a 128-bit symmetric block cipher that is provided within the library.  The cipher itself is flexible enough
+to allow some trade-offs in the implementation.  When TWOFISH\_SMALL is defined the scheduled symmetric key for Twofish 
+requires only 200 bytes of memory.  This is achieved by not pre-computing the substitution boxes.  Having this 
+defined will also greatly slow down the cipher.  When this macro is not defined Twofish will pre-compute the 
+tables at a cost of 4KB of memory.  The cipher will be much faster as a result.  
+
+When TWOFISH\_TABLES is defined the cipher will use pre-computed (and fixed in code) tables required to work.  This is
+useful when TWOFISH\_SMALL is defined as the table values are computed on the fly.  When this is defined the code size
+will increase by approximately 500 bytes.  If this is defined but TWOFISH\_SMALL is not the cipher will still work but
+it will not speed up the encryption or decryption functions.
+
+\subsection{GCM\_TABLES}
+When defined GCM will use a 64KB table (per GCM state) which will greatly speed up the per--packet latency.  
+It also increases the initialization time and is not suitable when you are going to use a key a few times only.  
+
+\subsection{GCM\_TABLES\_SSE2}
+\index{SSE2}
+When defined GCM will use the SSE2 instructions to perform the $GF(2^x)$ multiply using 16 128--bit XOR operations.  It shaves a few cycles per byte
+of GCM output on both the AMD64 and Intel Pentium 4 platforms.  Requires GCC and an SSE2 equipped platform.
+
+\subsection{LTC\_SMALL\_CODE}
+When this is defined some of the code such as the Rijndael and SAFER+ ciphers are replaced with smaller code variants.
+These variants are slower but can save quite a bit of code space.
+
+\subsection{LTC\_PTHREAD}
+When this is activated all of the descriptor table functions will use pthread locking to ensure thread safe updates to the tables.  Note that 
+it doesn't prevent a thread that is passively using a table from being messed up by another thread that updates the table.
+
+Generally the rule of thumb is to setup the tables once at startup and then leave them be.  This added build flag simply makes updating
+the tables safer.
+
+\subsection{LTC\_ECC\_TIMING\_RESISTANT}
+When this has been defined the ECC point multiplier (built--in to the library) will use a timing resistant point multiplication
+algorithm which prevents leaking key bits of the private key (scalar).  It is a slower algorithm but useful for situations
+where timing side channels pose a significant threat.
+
+\subsection{Math Descriptors}
+The library comes with three math descriptors that allow you to interface the public key cryptography API to freely available math
+libraries.  When \textbf{GMP\_DESC}, \textbf{LTM\_DESC}, or \textbf{TFM\_DESC} are defined
+descriptors for the respective library are built and included in the library as \textit{gmp\_desc}, \textit{ltm\_desc}, or \textit{tfm\_desc} respectively.
+
+In the test demos that use the libraries the additional flags \textbf{USE\_GMP}, \textbf{USE\_LTM}, and \textbf{USE\_TFM} can be defined
+to tell the program which library to use.  Only one of the USE flags can be defined at once.
+
+\index{GMP\_DESC} \index{USE\_GMP} \index{LTM\_DESC} \index{TFM\_DESC} \index{USE\_LTM} \index{USE\_TFM}
+\begin{small}
+\begin{verbatim}
+CFLAGS="-DGMP_DESC -DLTM_DESC -DTFM_DESC -DUSE_TFM" \
+EXTRALIBS="-lgmp -ltommath -ltfm" make -f makefile.shared install timing
+\end{verbatim}
+\end{small}
+
+That will build and install the library with all descriptors (and link against all), but only use TomsFastMath in the timing demo.  
+
+\chapter{Optimizations}
+\mysection{Introduction}
+The entire API was designed with plug and play in mind at the low level.  That is you can swap out any cipher, hash, PRNG or bignum library and the dependent API will not 
+require updating.  This has the nice benefit that one can add ciphers (etc.) not have to re--write portions of the API.  For the most part, LibTomCrypt has also been written
+to be highly portable and easy to build out of the box on pretty much any platform.  As such there are no assembler inlines throughout the code, I make no assumptions
+about the platform, etc...
+
+That works well for most cases but there are times where performance is of the essence.  This API allows optimized routines to be dropped in--place of the existing
+portable routines.  For instance, hand optimized assembler versions of AES could be provided.  Any existing function that uses the cipher could automatically use
+the optimized code without re--writing.  This also paves the way for hardware drivers that can access hardware accelerated cryptographic devices.
+
+At the heart of this flexibility is the \textit{descriptor} system.  A descriptor is essentially just a C \textit{struct} which describes the algorithm and provides pointers
+to functions that do the required work.  For a given class of operation (e.g. cipher, hash, prng, bignum) the functions of a descriptor have identical prototypes which makes 
+development simple.  In most dependent routines all an end developer has to do is register\_XXX() the descriptor and they are set.
+
+\mysection{Ciphers}
+The ciphers in LibTomCrypt are accessed through the ltc\_cipher\_descriptor structure.
+

+
+\subsection{Name}
+\index{find\_cipher()}
+The \textit{name} parameter specifies the name of the cipher.  This is what a developer would pass to find\_cipher() to find the cipher in the descriptor
+tables.
+
+\subsection{Internal ID}
+This is a single byte Internal ID you can use to distinguish ciphers from each other.
+
+\subsection{Key Lengths}
+The minimum key length is \textit{min\_key\_length} and is measured in octets.  Similarly the maximum key length is \textit{max\_key\_length}.  They can be equal
+and both must valid key sizes for the cipher.  Values in between are not assumed to be valid though they may be.
+
+\subsection{Block Length}
+The size of the ciphers plaintext or ciphertext is \textit{block\_length} and is measured in octets.
+
+\subsection{Rounds}
+Some ciphers allow different number of rounds to be used.  Usually you just use the default.  The default round count is \textit{default\_rounds}.
+
+\subsection{Setup}
+To initialize a cipher (for ECB mode) the function setup() was provided.  It accepts an array of key octets \textit{key} of length \textit{keylen} octets.  The user
+can specify the number of rounds they want through \textit{num\_rounds} where $num\_rounds = 0$ means use the default.  The destination of a scheduled key is stored
+in \textit{skey}.
+
+Inside the \textit{symmetric\_key} union there is a \textit{void *data} which you can use to allocate data if you need a data structure that does not fit with the existing
+ones provided.  Just make sure in your \textit{done()} function that you free the allocated memory.
+
+\subsection{Single block ECB}
+To process a single block in ECB mode the ecb\_encrypt() and ecb\_decrypt() functions were provided.  The plaintext and ciphertext buffers are allowed to overlap so you 
+must make sure you do not overwrite the output before you are finished with the input.
+
+\subsection{Testing}
+The test() function is used to self--test the \textit{device}.  It takes no arguments and returns \textbf{CRYPT\_OK} if all is working properly.  You may return
+\textbf{CRYPT\_NOP} to indicate that no testing was performed.
+
+\subsection{Key Sizing}
+Occasionally, a function will want to find a suitable key size to use since the input is oddly sized.  The keysize() function is for this case.  It accepts a 
+pointer to an integer which represents the desired size.  The function then has to match it to the exact or a lower key size that is valid for the cipher.  For
+example, if the input is $25$ and $24$ is valid then it stores $24$ back in the pointed to integer.  It must not round up and must return an error if the keysize
+ cannot be mapped to a valid key size for the cipher.
+
+\subsection{Acceleration}
+The next set of functions cover the accelerated functionality of the cipher descriptor.  Any combination of these functions may be set to \textbf{NULL} to indicate
+it is not supported.  In those cases the software defaults are used (using the single ECB block routines).
+
+\subsubsection{Accelerated ECB}
+These two functions are meant for cases where a user wants to encrypt (in ECB mode no less) an array of blocks.  These functions are accessed
+through the accel\_ecb\_encrypt and accel\_ecb\_decrypt pointers.  The \textit{blocks} count is the number of complete blocks to process.
+
+\subsubsection{Accelerated CBC} 
+These two functions are meant for accelerated CBC encryption.  These functions are accessed through the accel\_cbc\_encrypt and accel\_cbc\_decrypt pointers.
+The \textit{blocks} value is the number of complete blocks to process.  The \textit{IV} is the CBC initial vector.  It is an input upon calling this function and must be
+updated by the function before returning.  
+
+\subsubsection{Accelerated CTR}
+This function is meant for accelerated CTR encryption.  It is accessible through the accel\_ctr\_encrypt pointer.
+The \textit{blocks} value is the number of complete blocks to process.  The \textit{IV} is the CTR counter vector.  It is an input upon calling this function and must be
+updated by the function before returning.  The \textit{mode} value indicates whether the counter is big (mode = CTR\_COUNTER\_BIG\_ENDIAN) or 
+little (mode = CTR\_COUNTER\_LITTLE\_ENDIAN) endian.
+
+This function (and the way it's called) differs from the other two since ctr\_encrypt() allows any size input plaintext.  The accelerator will only be
+called if the following conditions are met.
+
+\begin{enumerate}
+   \item The accelerator is present
+   \item The CTR pad is empty
+   \item The remaining length of the input to process is greater than or equal to the block size.
+\end{enumerate}
+
+The \textit{CTR pad} is empty when a multiple (including zero) blocks of text have been processed.  That is, if you pass in seven bytes to AES--CTR mode you would have to 
+pass in a minimum of nine extra bytes before the accelerator could be called.  The CTR accelerator must increment the counter (and store it back into the 
+buffer provided) before encrypting it to create the pad.  
+
+The accelerator will only be used to encrypt whole blocks.  Partial blocks are always handled in software.
+
+\subsubsection{Accelerated LRW}
+These functions are meant for accelerated LRW.  They process blocks of input in lengths of multiples of 16 octets.  They must accept the \textit{IV} and \textit{tweak}
+state variables and updated them prior to returning.  Note that you may want to disable \textbf{LRW\_TABLES} in \textit{tomcrypt\_custom.h} if you intend
+to use accelerators for LRW.
+
+While both encrypt and decrypt accelerators are not required it is suggested as it makes lrw\_setiv() more efficient.
+
+Note that calling lrw\_done() will only invoke the cipher\_descriptor[].done() function on the \textit{symmetric\_key} parameter of the LRW state.  That means 
+if your device requires any (LRW specific) resources you should free them in your ciphers() done function.  The simplest way to think of it is to write
+the plugin solely to do LRW with the cipher.  That way cipher\_descriptor[].setup() means to init LRW resources and cipher\_descriptor[].done() means to
+free them.
+
+\subsubsection{Accelerated CCM}
+This function is meant for accelerated CCM encryption or decryption.  It processes the entire packet in one call.  You can optimize the work flow somewhat
+by allowing the caller to call the setup() function first to schedule the key if your accelerator cannot do the key schedule on the fly (for instance).  This 
+function MUST support both key passing methods.
+
+\begin{center}
+\begin{small}
+\begin{tabular}{|r|r|l|}
+\hline \textbf{key} & \textbf{uskey} & \textbf{Source of key} \\
+\hline NULL         & NULL           & Error, not supported \\
+\hline non-NULL     & NULL           & Use key, do a key schedule \\
+\hline NULL         & non-NULL       & Use uskey, key schedule not required \\
+\hline non-NULL     & non-NULL       & Use uskey, key schedule not required \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+
+\index{ccm\_memory()} This function is called when the user calls ccm\_memory().
+
+\subsubsection{Accelerated GCM}
+\index{gcm\_memory()}
+This function is meant for accelerated GCM encryption or decryption.  It processes the entire packet in one call.  Note that the setup() function will not
+be called prior to this.  This function must handle scheduling the key provided on its own.  It is called when the user calls gcm\_memory().
+
+\subsubsection{Accelerated OMAC}
+\index{omac\_memory()}
+This function is meant to perform an optimized OMAC1 (CMAC) message authentication code computation when the user calls omac\_memory().  
+
+\subsubsection{Accelerated XCBC-MAC}
+\index{xcbc\_memory()}
+This function is meant to perform an optimized XCBC-MAC message authentication code computation when the user calls xcbc\_memory().  
+
+\subsubsection{Accelerated F9}
+\index{f9\_memory()}
+This function is meant to perform an optimized F9 message authentication code computation when the user calls f9\_memory().  Like f9\_memory(), it requires
+the caller to perform any 3GPP related padding before calling in order to ensure proper compliance with F9.
+
+
+\mysection{One--Way Hashes}
+The hash functions are accessed through the ltc\_hash\_descriptor structure.
+
+\begin{small}

+                             unsigned long *outlen);
+};
+\end{verbatim}
+\end{small}
+
+\subsection{Name}
+This is the name the hash is known by and what find\_hash() will look for.
+
+\subsection{Internal ID}
+This is the internal ID byte used to distinguish the hash from other hashes.
+
+\subsection{Digest Size}
+The \textit{hashsize} variable indicates the length of the output in octets.
+
+\subsection{Block Size}
+The \textit{blocksize} variable indicates the length of input (in octets) that the hash processes in a given
+invocation.
+
+\subsection{OID Identifier}
+This is the universal ASN.1 Object Identifier for the hash.
+
+\subsection{Initialization}
+The init function initializes the hash and prepares it to process message bytes.
+
+\subsection{Process}
+This processes message bytes.  The algorithm must accept any length of input that the hash would allow.  The input is not
+guaranteed to be a multiple of the block size in length.
+
+\subsection{Done}
+The done function terminates the hash and returns the message digest.
+
+\subsection{Acceleration}
+A compatible accelerator must allow processing data in any granularity which may require internal padding on the driver side.
+
+\subsection{HMAC Acceleration}
+The hmac\_block() callback is meant for single--shot optimized HMAC implementations.  It is called directly by hmac\_memory() if present.  If you need
+to be able to process multiple blocks per MAC then you will have to simply provide a process() callback and use hmac\_memory() as provided in LibTomCrypt.
+

+
+\subsection{Name}
+The name by which find\_prng() will find the PRNG.
+
+\subsection{Export Size}
+When an PRNG state is to be exported for future use you specify the space required in this variable.
+
+\subsection{Start}
+Initialize the PRNG and make it ready to accept entropy.
+
+\subsection{Entropy Addition}
+Add entropy to the PRNG state.  The exact behaviour of this function depends on the particulars of the PRNG.
+
+\subsection{Ready}
+This function makes the PRNG ready to read from by processing the entropy added.  The behaviour of this function depends
+on the specific PRNG used.
+
+\subsection{Read}
+Read from the PRNG and return the number of bytes read.  This function does not have to fill the buffer but it is best 
+if it does as many protocols do not retry reads and will fail on the first try.
+
+\subsection{Done}
+Terminate a PRNG state.  The behaviour of this function depends on the particular PRNG used.
+
+\subsection{Exporting and Importing}
+An exported PRNG state is data that the PRNG can later import to resume activity.  They're not meant to resume \textit{the same session}
+but should at least maintain the same level of state entropy.
+
+\mysection{BigNum Math Descriptors}

+
+Most of the functions are fairly straightforward and do not need documentation.  We'll cover the basic conventions of the API and then explain the accelerated functions.
+
+\subsection{Conventions}
+
+All \textit{bignums} are accessed through an opaque \textit{void *} data type.  You must internally cast the pointer if you need to access members of your bignum structure.  During
+the init calls a \textit{void **} will be passed where you allocate your structure and set the pointer then initialize the number to zero.  During the deinit calls you must 
+free the bignum as well as the structure you allocated to place it in.
+
+All functions except the Montgomery reductions work from left to right with the arguments.  For example, mul(a, b, c) computes $c \leftarrow ab$.  
+
+All functions (except where noted otherwise) return \textbf{CRYPT\_OK} to signify a successful operation.  All error codes must be valid LibTomCrypt error codes.
+
+The digit routines (including functions with the \textit{i} suffix) use a \textit{unsigned long} to represent the digit.  If your internal digit is larger than this you must
+then partition your digits.  Normally this does not matter as \textit{unsigned long} will be the same size as your register size.  Note that if your digit is smaller
+than an \textit{unsigned long} that is also acceptable as the \textit{bits\_per\_digit} parameter will specify this.  
+
+\subsection{ECC Functions}
+The ECC system in LibTomCrypt is based off of the NIST recommended curves over $GF(p)$ and is used to implement EC-DSA and EC-DH.   The ECC functions work with 
+the \textbf{ecc\_point} structure and assume the points are stored in Jacobian projective format.
+
+\begin{verbatim}
+/** A point on a ECC curve, stored in Jacobian format such 
+    that (x,y,z) => (x/z^2, y/z^3, 1) when interpreted as affine */
+typedef struct {
+    /** The x co-ordinate */
+    void *x;
+    /** The y co-ordinate */
+    void *y;
+    /** The z co-ordinate */
+    void *z;
+} ecc_point;
+\end{verbatim}
+
+All ECC functions must use this mapping system.  The only exception is when you remap all ECC callbacks which will allow you to have more control
+over how the ECC math will be implemented.  Out of the box you only have three parameters per point to use $(x, y, z)$ however, these are just void pointers.  They
+could point to anything you want.  The only further exception is the export functions which expects the values to be in affine format.
+
+\subsubsection{Point Multiply}
+This will multiply the point $G$ by the scalar $k$ and store the result in the point $R$.  The value should be mapped to affine only if $map$ is set to one.  
+
+\subsubsection{Point Addition}
+This will add the point $P$ to the point $Q$ and store it in the point $R$.  The $mp$ parameter is the \textit{b} value from the montgomery\_setup() call.  The input points
+may be in either affine (with $z = 1$) or projective format and the output point is always projective.  
+
+\subsubsection{Point Mapping}
+This will map the point $P$ back from projective to affine.  The output point $P$ must be of the form $(x, y, 1)$.  
+
+\subsubsection{Shamir's Trick}
+\index{Shamir's Trick}
+\index{ltc\_ecc\_mul2add()}
+To accelerate EC--DSA verification the library provides a built--in function called ltc\_ecc\_mul2add().  This performs two point multiplications and an addition in
+roughly the time of one point multiplication.  It is called from ecc\_verify\_hash() if an accelerator is not present.  The acclerator function must allow the points to
+overlap (e.g., $A \leftarrow k_1A + k_2B$) and must return the final point in affine format.  
+
+
+\subsection{RSA Functions}
+The RSA Modular Exponentiation (ME) function is used by the RSA API to perform exponentiations for private and public key operations.  In particular for
+private key operations it uses the CRT approach to lower the time required.  It is passed an RSA key with the following format.
+
+\begin{verbatim}
+/** RSA PKCS style key */
+typedef struct Rsa_key {
+    /** Type of key, PK_PRIVATE or PK_PUBLIC */
+    int type;
+    /** The public exponent */
+    void *e; 
+    /** The private exponent */
+    void *d; 
+    /** The modulus */
+    void *N; 
+    /** The p factor of N */
+    void *p; 
+    /** The q factor of N */
+    void *q; 
+    /** The 1/q mod p CRT param */
+    void *qP; 
+    /** The d mod (p - 1) CRT param */
+    void *dP; 
+    /** The d mod (q - 1) CRT param */
+    void *dQ;
+} rsa_key;
+\end{verbatim}
+
+The call reads the \textit{in} buffer as an unsigned char array in big endian format.  Then it performs the exponentiation and stores the output in big endian format
+to the \textit{out} buffer.  The output must be zero padded (leading bytes) so that the length of the output matches the length of the modulus (in bytes).  For example,
+for RSA--1024 the output is always 128 bytes regardless of how small the numerical value of the exponentiation is.
+
+Since the function is given the entire RSA key (for private keys only) CRT is possible as prescribed in the PKCS \#1 v2.1 specification.

+Tech Note 0001
+How to Gather Entropy on Embedded Systems
+Tom St Denis
+
+Introduction
+------------
+
+This tech note explains a relatively simple way to gather entropy for a PRNG (Yarrow in this case) in embedded systems
+where there are few sources of entropy or physical sources.
+
+When trying to setup a secure random number generator a fresh source of random data (entropy) is required to ensure the
+deterministic state of the PRNG is not known or predetermined with respect to an attacker.
+
+At the very least the system requires one timer and one source of un-timed interrupts.  by "un-timed" I mean interrupts
+that do not occur at regular intervals [e.g. joypad/keypad input, network packets, etc...].
+
+First we shall begin by taking an overview of how the Yarrow PRNG works within libtomcrypt.  At the heart of all
+PRNGs is the "prng_state" data type.  This is a union of structures that hold the PRNG state for the various prngs.  The 
+first thing we require is a state... 
+
+   prng_state myPrng;
+
+Next we must initialize the state once to get the ball rolling
+
+   if (yarrow_start(&myPrng) != CRYPT_OK) {
+      // error should never happen!
+   }
+
+At this point the PRNG is ready to accept fresh entropy which is added with
+
+   int yarrow_add_entropy(const unsigned char *buf, unsigned long len, prng_state *prng)
+
+This function is **NOT** thread safe which will come under consideration later.  To add entropy to our PRNG we must 
+call this function with fresh data as its sampled.  Lets say we have a timer counter called "uTimer" which is a 32-bit 
+long and say a 32-bit joyPad state called "uPad".  An example interrupt handler would look like
+
+   void joypad_interrupt(...) {
+       unsigned char buf[8];
+
+       STORE32L(uTimer, buf);
+       STORE32L(uPad, buf+4)
+       if (yarrow_add_entropy(buf, 8, &myPrng) != CRYPT_OK) {
+          // this should never occur either unless you didn't call yarrow_start
+       }
+ 
+       // handle interrupt
+   }
+
+In this snippet the timer count and state of the joypad are added together into the entropy pool.  The timer is important
+because with respect to the joypad it is a good source of entropy (on its own its not).  For example, the probability of
+the user pushing the up arrow is fairly high, but at a specific time is not.
+
+This method doesn't gather alot of entropy and has to be used to for quite a while.  One way to speed it up is to tap
+multiple sources.  If you have a network adapter and other sources of events (keyboard, mouse, etc...) trapping their
+data is ideal as well.  Its important to gather the timer along with the event data.
+
+As mentioned the "yarrow_add_entropy()" function is not thread safe.  If your system allows interrupt handlers to be 
+interrupted themselves then you could have trouble.  One simple way is to detect when an interrupt is in progress and
+simply not add entropy during the call (jump over the yarrow_add_entropy() call)
+
+Once you feel that there has been enough entropy added to the pool then within a single thread you can call
+
+    int yarrow_ready(prng_state *prng)
+
+Now the PRNG is ready to read via the 
+
+    unsigned long yarrow_read(unsigned char *buf, unsigned long len, prng_state *prng)
+
+It is a very good idea that once you call the yarrow_ready() function that you stop harvesting entropy in your interrupt
+functions.  This will free up alot of CPU time.  Also one more final note.  The yarrow_read() function is not thread
+safe either.  This means if you have multiple threads or processes that read from it you will have to add your own semaphores
+around calls to it.

+Tech Note 0002
+How to avoid non-intrusive timing attacks with online computations
+Tom St Denis
+
+Introduction
+------------
+
+A timing attack is when an attacker can observe a side channel of the device (in this case time).  In this tech note
+we consider only non-intrusive timing attacks with respect to online computations.  That is an attacker can
+determine when a computation (such as a public key encryption) begins and ends but cannot observe the device 
+directly.  This is specifically important for applications which transmit data via a public network.
+
+Consider a Diffie-Hellman encryption which requires the sender to make up a public key "y = g^x mod p".  Libtomcrypt
+uses the MPI bignum library to perform the operation.  The time it takes to compute y is controlled by the number
+of 1 bits in the exponent 'x'.  To a large extent there will be the same number of squaring operations.  "1" bits in
+the exponent require the sender to perform a multiplication.  This means to a certain extent an attacker can 
+determine not only the magnitude of 'x' but the number of one bits.  With this information the attacker cannot directly
+learn the key used.  However, good cryptography mandates the close scrutiny of any practical side channel.
+
+Similar logic applies to the other various routines.  Fortunately for this case there is a simple solution.  First, 
+determine the maximum time the particular operation can require.  For instance, on an Athlon 1.53Ghz XP processor a
+DH-768 encryption requires roughly 50 milliseconds.  Take that time and round it up.  Now place a delay after the call.
+
+For example, 
+
+void demo(void) {
+   clock_t t1;
+
+   // get initial clock
+   t1 = clock();
+   
+   // some PK function
+   
+   // now delay 
+   while (clock() < (t1 + 100));
+   
+   // transmit data...
+   
+}
+
+This code has the effect of taking at least 100 ms always.  In effect someone analyzing the traffic will see that the
+operations always take a fixed amount of time.  Since no two platforms are the same this type of fix has not been 
+incorporated into libtomcrypt (nor is it desired for many platforms).  This requires on the developers part to profile
+the code to determine the delays required.
+
+Note that this "quick" fix has no effect against an intrusive attacker.  For example, power consumption will drop
+significantly in the loop after the operation.  However, this type of fix is more important to secure the user of the 
+application/device.  For example, a user placing an order online won't try to cheat themselves by cracking open their
+device and performing side-channel cryptanalysis.  An attacker over a network might try to use the timing information
+against the user.

+Minimizing Memory Usage
+Tom St Denis
+
+Introduction
+------------
+
+For the most part the library can get by with around 20KB of stack and about 32KB of heap even if you use the
+public key functions.  If all you plan on using are the hashes and ciphers than only about 1KB of stack is required
+and no heap.
+
+To save space all of the symmetric key scheduled keys are stored in a union called "symmetric_key".  This means the 
+size of a symmetric_key is the size of the largest scheduled key.  By removing the ciphers you don't use from
+the build you can minimize the size of this structure.  For instance, by removing both Twofish and Blowfish the
+size reduces to 768 bytes from the 4,256 bytes it would have been (on a 32-bit platform).  Or if you remove
+Blowfish and use Twofish with TWOFISH_SMALL defined its still 768 bytes.  Even at its largest the structure is only 
+4KB which is normally not a problem for any platform.  
+

+Noekeon is a fairly fast cipher and uses very little memory.  Ideally in low-ram platforms all other ciphers should be

+fairly fast as well.

+Tech Note 0004
+Using Yarrow, Fortuna and SOBER-128
+Tom St Denis
+
+Introduction
+------------
+
+This tech note explains how to use three of the more useful pseudo random number generators and their 
+own little "issues".  While all of the PRNGs have the same API and are roughly used in the same 
+manner their effectiveness really depends on the user knowing how they work.
+
+
+Yarrow
+------
+
+Yarrow is by far the simplest of the PRNGs.  It gathers bits of entropy by hashing the pool state
+plus the additional bits storing the message digest back in the pool.  E.g.
+
+pool = hash(pool || newbits)
+
+Simply dump bits into the PRNG via yarrow_add_entropy() and call yarrow_ready() when you want to 
+put them to use.  This PRNG while simple is not entirely safe.  An attacker who learns the state
+of the pool and can control future events can control the PRNG.  This requires an active attacker but 
+isn't entire impossible.
+
+The pool is then used as a key for a cipher that is used in CTR mode.  
+
+Yarrow is mostly meant for short-term programs [e.g. like file utils].  This particular implementation
+is not meant for long-term usage.
+
+Fortuna
+-------
+
+Fortuna was designed by Niels Fergusson and Bruce Schneier [Bruce is also the guy who invented Yarrow].  It
+operates on a more defensive level than Yarrow.  Instead of 1 entropy pool it has 32 and the new entropy 
+is spread [round robin] in all of the pools. 
+
+That is, each call to fortuna_add_entropy() puts the bits in the next [in the sequenece] pool of entropy.  
+Effective bits are added to the pool by sending them through a hash [but not terminating the hash].  
+
+Here's the main catch though.  When the PRNG must be reseeded [so that you can extract bits from it] only
+certain pools are used.  More precisely the i'th pool is used every 2**i'th reseeding.  For example, pool[0]
+is always used.  pool[1] is used every second reseeding, pool[2] every fourth.
+
+The pools are hashed together along with the current key and the result is the new key for a cipher which
+operates in CTR mode [more about that in a sec].
+
+Now this may seem odd at first however there is a good reason behind it.  An attacker who learns pool[0] won't
+strictly know the other pools.  So the recovery rate of is not 0.  In fact pool[0] can be completely 
+compromised and the PRNG will still eventually recover.  The value FORTUNA_WD is the "WatchDog" counter.
+Every FORTUNA_WD calls to fortuna_read will invoke the reseed operation.  By default this is set to 10 which 
+means after 10 calls the PRNG will reseed itself.  
+
+The pools are combined with the running cipher key [256 bits] so that a cipher in CTR mode can produce 
+the stream.  Unlike Yarrow the cipher is re-keyed after every call to fortuna_read() [so one big call 
+would be faster than many smaller calls].  This prevents too much data being encrypted under the same
+key [and mitigates a flaw in CTR mode that the same block can't be emitted twice under the same key].
+
+Fortuna is really meant for a kernel-level PRNG.  The more sources [and often] you feed into it the 
+healthier it will be.  It's also meant to be used for long term purposes.  Since it can recover from
+compromises it is harder to control it.  
+
+SOBER-128
+------
+
+SOBER-128 is actually a stream cipher but like most ciphers can easily be modelled in the context of a PRNG.
+This PRNG is extremely fast [4 cycles/byte on a P4] and was designed by a well known cryptographer [Greg Rose].
+
+SOBER-128 doesn't really "act" like the other two PRNGs.  It's meant to be seeded once and then read as 
+required.  In such a sense it isn't a "system PRNG" but useful short term purposes.  In particular
+the sober128_read() function actually XORs against the input buffer you specify.  This allows the 
+read() function to be used as an "encrypt" function as well.  
+
+You can only key SOBER-128 once [by calling sober128_add_entropy()].  Once it it is keyed subsequent
+calls to add_entropy() will be considered a "re-IV" operation.  Changing the IV allows you to use same
+initial key and not produce the same output stream.  It also lets you differentiate packets.  E.g. each
+packet has it's own IV.
+
+All inputs to sober128_add_entropy() must have a length that is a multiple of four.
+
+Overall
+-------
+
+Since SOBER-128 is *much* faster than the other two PRNGs a good setup would be to use Fortuna as your 
+system-wide PRNG and use SOBER-128 [key'ed from Fortuna] for encrypting streams or as a PRNG for 
+simulations.
+
+Yarrow is still a good candidate but only for "short lived" programs.  However, since Fortuna is faster
+[by about 10 cycles/byte on a P4] I'd use Fortuna anyways...

+Introduction
+------------
+
+Tweaking...
+
+You can disable whole classes of algorithms on the command line with the LTC_NO_* defines.  From there you can manually turn on what you want to enable.  
+
+The following build with GCC 3.4.4 on an AMD64 box gets you AES, CTR mode, SHA-256, HMAC, Yarrow, full RSA PKCS #1, PKCS #5 and ASN.1 DER in 
+roughly 40KB of code (49KB on the ARMv4) (both excluding the math library).
+
+CFLAGS="-DLTC_NO_CIPHERS -DLTC_NO_HASHES -DLTC_NO_PRNGS -DLTC_NO_MACS -DLTC_NO_MODES -DLTC_NO_PK -DRIJNDAEL -DLTC_CTR_MODE -DSHA256 \
+-DLTC_HMAC -DYARROW -DMRSA -DMPI -DTFM_DESC -DARGTYPE=3 -Os -DLTC_SMALL_CODE -fomit-frame-pointer" make IGNORE_SPEED=1
+
+Obviously this won't get you performance but if you need to pack a crypto lib in a device with limited means it's more than enough...
+
+Neato eh?

+ECC
+----
+
+The ANSI X9.62 and X9.63 algorithms [partial].  Supports all NIST GF(p) curves.
+
+Key Format   :  Homebrew [see below, only GF(p) NIST curves supported]
+Signature    :  X9.62 compliant
+Encryption   :  Homebrew [based on X9.63, differs in that the public point is stored as an ECCPublicKey]
+Shared Secret:  X9.63 compliant
+
+ECCPublicKey ::= SEQUENCE {
+    flags       BIT STRING(1), -- public/private flag (always zero), 
+    keySize     INTEGER,       -- Curve size (in bits) divided by eight 
+                               -- and rounded down, e.g. 521 => 65
+    pubkey.x    INTEGER,       -- The X co-ordinate of the public key point
+    pubkey.y    INTEGER,       -- The Y co-ordinate of the public key point
+}
+
+ECCPrivateKey ::= SEQUENCE {
+    flags       BIT STRING(1), -- public/private flag (always one), 
+    keySize     INTEGER,       -- Curve size (in bits) divided by eight 
+                               -- and rounded down, e.g. 521 => 65
+    pubkey.x    INTEGER,       -- The X co-ordinate of the public key point
+    pubkey.y    INTEGER,       -- The Y co-ordinate of the public key point
+    secret.k    INTEGER,       -- The secret key scalar
+}
+
+The encryption works by finding the X9.63 shared secret and hashing it.  The hash is then simply XOR'ed against the message [which must be at most the size
+of the hash digest].  The format of the encrypted text is as follows
+
+ECCEncrypted ::= SEQUENCE {
+    hashOID     OBJECT IDENTIFIER,   -- The OID of the hash used
+    pubkey      OCTET STRING     ,   -- Encapsulation of a random ECCPublicKey
+    skey        OCTET STRING         -- The encrypted text (which the hash was XOR'ed against)
+}

+\chapter{Introduction}
+\section{What is LibTomMath?}
+LibTomMath is a library of source code which provides a series of efficient and carefully written functions for manipulating
+large integer numbers.  It was written in portable ISO C source code so that it will build on any platform with a conforming
+C compiler.  
+
+In a nutshell the library was written from scratch with verbose comments to help instruct computer science students how
+to implement ``bignum'' math.  However, the resulting code has proven to be very useful.  It has been used by numerous 
+universities, commercial and open source software developers.  It has been used on a variety of platforms ranging from
+Linux and Windows based x86 to ARM based Gameboys and PPC based MacOS machines.  
+
+\section{License}
+As of the v0.25 the library source code has been placed in the public domain with every new release.  As of the v0.28
+release the textbook ``Implementing Multiple Precision Arithmetic'' has been placed in the public domain with every new
+release as well.  This textbook is meant to compliment the project by providing a more solid walkthrough of the development
+algorithms used in the library.
+
+Since both\footnote{Note that the MPI files under mtest/ are copyrighted by Michael Fromberger.  They are not required to use LibTomMath.} are in the 
+public domain everyone is entitled to do with them as they see fit.
+
+\section{Building LibTomMath}
+
+LibTomMath is meant to be very ``GCC friendly'' as it comes with a makefile well suited for GCC.  However, the library will
+also build in MSVC, Borland C out of the box.  For any other ISO C compiler a makefile will have to be made by the end
+developer.  
+
+\subsection{Static Libraries}
+To build as a static library for GCC issue the following
+\begin{alltt}
+make
+\end{alltt}
+
+command.  This will build the library and archive the object files in ``libtommath.a''.  Now you link against 
+that and include ``tommath.h'' within your programs.  Alternatively to build with MSVC issue the following
+\begin{alltt}
+nmake -f makefile.msvc
+\end{alltt}
+
+This will build the library and archive the object files in ``tommath.lib''.  This has been tested with MSVC 
+version 6.00 with service pack 5.  
+
+\subsection{Shared Libraries}
+To build as a shared library for GCC issue the following
+\begin{alltt}
+make -f makefile.shared
+\end{alltt}
+This requires the ``libtool'' package (common on most Linux/BSD systems).  It will build LibTomMath as both shared
+and static then install (by default) into /usr/lib as well as install the header files in /usr/include.  The shared 
+library (resource) will be called ``libtommath.la'' while the static library called ``libtommath.a''.  Generally 
+you use libtool to link your application against the shared object.  
+
+There is limited support for making a ``DLL'' in windows via the ``makefile.cygwin\_dll'' makefile.  It requires 
+Cygwin to work with since it requires the auto-export/import functionality.  The resulting DLL and import library 
+``libtommath.dll.a'' can be used to link LibTomMath dynamically to any Windows program using Cygwin.
+
+\subsection{Testing}
+To build the library and the test harness type
+
+\begin{alltt}
+make test
+\end{alltt}
+
+This will build the library, ``test'' and ``mtest/mtest''.  The ``test'' program will accept test vectors and verify the
+results.  ``mtest/mtest'' will generate test vectors using the MPI library by Michael Fromberger\footnote{A copy of MPI
+is included in the package}.  Simply pipe mtest into test using
+
+\begin{alltt}
+mtest/mtest | test
+\end{alltt}
+
+If you do not have a ``/dev/urandom'' style RNG source you will have to write your own PRNG and simply pipe that into 
+mtest.  For example, if your PRNG program is called ``myprng'' simply invoke
+
+\begin{alltt}
+myprng | mtest/mtest | test
+\end{alltt}
+
+This will output a row of numbers that are increasing.  Each column is a different test (such as addition, multiplication, etc)
+that is being performed.  The numbers represent how many times the test was invoked.  If an error is detected the program
+will exit with a dump of the relevent numbers it was working with.
+
+\section{Build Configuration}
+LibTomMath can configured at build time in three phases we shall call ``depends'', ``tweaks'' and ``trims''.  
+Each phase changes how the library is built and they are applied one after another respectively.  
+
+To make the system more powerful you can tweak the build process.  Classes are defined in the file
+``tommath\_superclass.h''.  By default, the symbol ``LTM\_ALL'' shall be defined which simply 
+instructs the system to build all of the functions.  This is how LibTomMath used to be packaged.  This will give you 
+access to every function LibTomMath offers.
+
+However, there are cases where such a build is not optional.  For instance, you want to perform RSA operations.  You 
+don't need the vast majority of the library to perform these operations.  Aside from LTM\_ALL there is 
+another pre--defined class ``SC\_RSA\_1'' which works in conjunction with the RSA from LibTomCrypt.  Additional 
+classes can be defined base on the need of the user.
+
+\subsection{Build Depends}
+In the file tommath\_class.h you will see a large list of C ``defines'' followed by a series of ``ifdefs''
+which further define symbols.  All of the symbols (technically they're macros $\ldots$) represent a given C source
+file.  For instance, BN\_MP\_ADD\_C represents the file ``bn\_mp\_add.c''.  When a define has been enabled the
+function in the respective file will be compiled and linked into the library.  Accordingly when the define
+is absent the file will not be compiled and not contribute any size to the library.
+
+You will also note that the header tommath\_class.h is actually recursively included (it includes itself twice).  
+This is to help resolve as many dependencies as possible.  In the last pass the symbol LTM\_LAST will be defined.  
+This is useful for ``trims''.
+
+\subsection{Build Tweaks}
+A tweak is an algorithm ``alternative''.  For example, to provide tradeoffs (usually between size and space).
+They can be enabled at any pass of the configuration phase.
+
+\begin{small}
+\begin{center}
+\begin{tabular}{|l|l|}
+\hline \textbf{Define} & \textbf{Purpose} \\
+\hline BN\_MP\_DIV\_SMALL & Enables a slower, smaller and equally \\
+                          & functional mp\_div() function \\
+\hline
+\end{tabular}
+\end{center}
+\end{small}
+
+\subsection{Build Trims}
+A trim is a manner of removing functionality from a function that is not required.  For instance, to perform
+RSA cryptography you only require exponentiation with odd moduli so even moduli support can be safely removed.  
+Build trims are meant to be defined on the last pass of the configuration which means they are to be defined
+only if LTM\_LAST has been defined.

+\section{Purpose of LibTomMath}
+Unlike  GNU MP (GMP) Library, LIP, OpenSSL or various other commercial kits (Miracl), LibTomMath was not written with 
+bleeding edge performance in mind.  First and foremost LibTomMath was written to be entirely open.  Not only is the 
+source code public domain (unlike various other GPL/etc licensed code), not only is the code freely downloadable but the
+source code is also accessible for computer science students attempting to learn ``BigNum'' or multiple precision
+arithmetic techniques. 
+
+LibTomMath was written to be an instructive collection of source code.  This is why there are many comments, only one
+function per source file and often I use a ``middle-road'' approach where I don't cut corners for an extra 2\% speed
+increase.
+
+Source code alone cannot really teach how the algorithms work which is why I also wrote a textbook that accompanies
+the library (beat that!).
+
+So you may be thinking ``should I use LibTomMath?'' and the answer is a definite maybe.  Let me tabulate what I think
+are the pros and cons of LibTomMath by comparing it to the math routines from GnuPG\footnote{GnuPG v1.2.3 versus LibTomMath v0.28}.
+
+\newpage\begin{figure}[here]
+\begin{small}
+\begin{center}
+\begin{tabular}{|l|c|c|l|}
+\hline \textbf{Criteria} & \textbf{Pro} & \textbf{Con} & \textbf{Notes} \\
+\hline Few lines of code per file & X & & GnuPG $ = 300.9$, LibTomMath  $ = 71.97$ \\
+\hline Commented function prototypes & X && GnuPG function names are cryptic. \\
+\hline Speed && X & LibTomMath is slower.  \\
+\hline Totally free & X & & GPL has unfavourable restrictions.\\
+\hline Large function base & X & & GnuPG is barebones. \\
+\hline Five modular reduction algorithms & X & & Faster modular exponentiation for a variety of moduli. \\
+\hline Portable & X & & GnuPG requires configuration to build. \\
+\hline
+\end{tabular}
+\end{center}
+\end{small}
+\caption{LibTomMath Valuation}
+\end{figure}
+
+It may seem odd to compare LibTomMath to GnuPG since the math in GnuPG is only a small portion of the entire application. 
+However, LibTomMath was written with cryptography in mind.  It provides essentially all of the functions a cryptosystem
+would require when working with large integers.  
+
+So it may feel tempting to just rip the math code out of GnuPG (or GnuMP where it was taken from originally) in your
+own application but I think there are reasons not to.  While LibTomMath is slower than libraries such as GnuMP it is
+not normally significantly slower.  On x86 machines the difference is normally a factor of two when performing modular
+exponentiations.  It depends largely on the processor, compiler and the moduli being used.
+
+Essentially the only time you wouldn't use LibTomMath is when blazing speed is the primary concern.  However,
+on the other side of the coin LibTomMath offers you a totally free (public domain) well structured math library
+that is very flexible, complete and performs well in resource contrained environments.  Fast RSA for example can
+be performed with as little as 8KB of ram for data (again depending on build options).  
+
+\chapter{Getting Started with LibTomMath}
+\section{Building Programs}
+In order to use LibTomMath you must include ``tommath.h'' and link against the appropriate library file (typically 
+libtommath.a).  There is no library initialization required and the entire library is thread safe.
+
+\section{Return Codes}
+There are three possible return codes a function may return.
+
+\index{MP\_OKAY}\index{MP\_YES}\index{MP\_NO}\index{MP\_VAL}\index{MP\_MEM}
+\begin{figure}[here!]
+\begin{center}
+\begin{small}
+\begin{tabular}{|l|l|}
+\hline \textbf{Code} & \textbf{Meaning} \\
+\hline MP\_OKAY & The function succeeded. \\
+\hline MP\_VAL  & The function input was invalid. \\
+\hline MP\_MEM  & Heap memory exhausted. \\
+\hline &\\
+\hline MP\_YES  & Response is yes. \\
+\hline MP\_NO   & Response is no. \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{Return Codes}
+\end{figure}
+
+The last two codes listed are not actually ``return'ed'' by a function.  They are placed in an integer (the caller must
+provide the address of an integer it can store to) which the caller can access.  To convert one of the three return codes
+to a string use the following function.
+
+\index{mp\_error\_to\_string}
+\begin{alltt}
+char *mp_error_to_string(int code);
+\end{alltt}
+
+This will return a pointer to a string which describes the given error code.  It will not work for the return codes 
+MP\_YES and MP\_NO.  
+
+\section{Data Types}
+The basic ``multiple precision integer'' type is known as the ``mp\_int'' within LibTomMath.  This data type is used to
+organize all of the data required to manipulate the integer it represents.  Within LibTomMath it has been prototyped
+as the following.
+
+\index{mp\_int}
+\begin{alltt}
+typedef struct  \{
+    int used, alloc, sign;
+    mp_digit *dp;
+\} mp_int;
+\end{alltt}
+
+Where ``mp\_digit'' is a data type that represents individual digits of the integer.  By default, an mp\_digit is the
+ISO C ``unsigned long'' data type and each digit is $28-$bits long.  The mp\_digit type can be configured to suit other
+platforms by defining the appropriate macros.  
+
+All LTM functions that use the mp\_int type will expect a pointer to mp\_int structure.  You must allocate memory to
+hold the structure itself by yourself (whether off stack or heap it doesn't matter).  The very first thing that must be
+done to use an mp\_int is that it must be initialized.
+
+\section{Function Organization}
+
+The arithmetic functions of the library are all organized to have the same style prototype.  That is source operands
+are passed on the left and the destination is on the right.  For instance,
+
+\begin{alltt}
+mp_add(&a, &b, &c);       /* c = a + b */
+mp_mul(&a, &a, &c);       /* c = a * a */
+mp_div(&a, &b, &c, &d);   /* c = [a/b], d = a mod b */
+\end{alltt}
+
+Another feature of the way the functions have been implemented is that source operands can be destination operands as well.
+For instance,
+
+\begin{alltt}
+mp_add(&a, &b, &b);       /* b = a + b */
+mp_div(&a, &b, &a, &c);   /* a = [a/b], c = a mod b */
+\end{alltt}
+
+This allows operands to be re-used which can make programming simpler.
+
+\section{Initialization}
+\subsection{Single Initialization}
+A single mp\_int can be initialized with the ``mp\_init'' function. 
+
+\index{mp\_init}
+\begin{alltt}
+int mp_init (mp_int * a);
+\end{alltt}
+
+This function expects a pointer to an mp\_int structure and will initialize the members of the structure so the mp\_int
+represents the default integer which is zero.  If the functions returns MP\_OKAY then the mp\_int is ready to be used
+by the other LibTomMath functions.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Single Free}
+When you are finished with an mp\_int it is ideal to return the heap it used back to the system.  The following function 
+provides this functionality.
+
+\index{mp\_clear}
+\begin{alltt}
+void mp_clear (mp_int * a);
+\end{alltt}
+
+The function expects a pointer to a previously initialized mp\_int structure and frees the heap it uses.  It sets the 
+pointer\footnote{The ``dp'' member.} within the mp\_int to \textbf{NULL} which is used to prevent double free situations. 
+Is is legal to call mp\_clear() twice on the same mp\_int in a row.  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   /* We're done with it. */
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Multiple Initializations}
+Certain algorithms require more than one large integer.  In these instances it is ideal to initialize all of the mp\_int
+variables in an ``all or nothing'' fashion.  That is, they are either all initialized successfully or they are all
+not initialized.
+
+The  mp\_init\_multi() function provides this functionality.
+
+\index{mp\_init\_multi} \index{mp\_clear\_multi}
+\begin{alltt}
+int mp_init_multi(mp_int *mp, ...);
+\end{alltt}
+
+It accepts a \textbf{NULL} terminated list of pointers to mp\_int structures.  It will attempt to initialize them all
+at once.  If the function returns MP\_OKAY then all of the mp\_int variables are ready to use, otherwise none of them
+are available for use.  A complementary mp\_clear\_multi() function allows multiple mp\_int variables to be free'd 
+from the heap at the same time.  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int num1, num2, num3;
+   int result;
+
+   if ((result = mp_init_multi(&num1, 
+                               &num2,
+                               &num3, NULL)) != MP\_OKAY) \{      
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the numbers */
+
+   /* We're done with them. */
+   mp_clear_multi(&num1, &num2, &num3, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Other Initializers}
+To initialized and make a copy of an mp\_int the mp\_init\_copy() function has been provided.  
+
+\index{mp\_init\_copy}
+\begin{alltt}
+int mp_init_copy (mp_int * a, mp_int * b);
+\end{alltt}
+
+This function will initialize $a$ and make it a copy of $b$ if all goes well.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int num1, num2;
+   int result;
+
+   /* initialize and do work on num1 ... */
+
+   /* We want a copy of num1 in num2 now */
+   if ((result = mp_init_copy(&num2, &num1)) != MP_OKAY) \{
+     printf("Error initializing the copy.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* now num2 is ready and contains a copy of num1 */
+
+   /* We're done with them. */
+   mp_clear_multi(&num1, &num2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+Another less common initializer is mp\_init\_size() which allows the user to initialize an mp\_int with a given
+default number of digits.  By default, all initializers allocate \textbf{MP\_PREC} digits.  This function lets
+you override this behaviour.
+
+\index{mp\_init\_size}
+\begin{alltt}
+int mp_init_size (mp_int * a, int size);
+\end{alltt}
+
+The $size$ parameter must be greater than zero.  If the function succeeds the mp\_int $a$ will be initialized
+to have $size$ digits (which are all initially zero).  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   /* we need a 60-digit number */
+   if ((result = mp_init_size(&number, 60)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\section{Maintenance Functions}
+
+\subsection{Reducing Memory Usage}
+When an mp\_int is in a state where it won't be changed again\footnote{A Diffie-Hellman modulus for instance.} excess
+digits can be removed to return memory to the heap with the mp\_shrink() function.
+
+\index{mp\_shrink}
+\begin{alltt}
+int mp_shrink (mp_int * a);
+\end{alltt}
+
+This will remove excess digits of the mp\_int $a$.  If the operation fails the mp\_int should be intact without the
+excess digits being removed.  Note that you can use a shrunk mp\_int in further computations, however, such operations
+will require heap operations which can be slow.  It is not ideal to shrink mp\_int variables that you will further
+modify in the system (unless you are seriously low on memory).  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number [e.g. pre-computation]  */
+
+   /* We're done with it for now. */
+   if ((result = mp_shrink(&number)) != MP_OKAY) \{
+      printf("Error shrinking the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* use it .... */
+
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Adding additional digits}
+
+Within the mp\_int structure are two parameters which control the limitations of the array of digits that represent
+the integer the mp\_int is meant to equal.   The \textit{used} parameter dictates how many digits are significant, that is,
+contribute to the value of the mp\_int.  The \textit{alloc} parameter dictates how many digits are currently available in
+the array.  If you need to perform an operation that requires more digits you will have to mp\_grow() the mp\_int to
+your desired size.  
+
+\index{mp\_grow}
+\begin{alltt}
+int mp_grow (mp_int * a, int size);
+\end{alltt}
+
+This will grow the array of digits of $a$ to $size$.  If the \textit{alloc} parameter is already bigger than
+$size$ the function will not do anything.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   /* We need to add 20 digits to the number  */
+   if ((result = mp_grow(&number, number.alloc + 20)) != MP_OKAY) \{
+      printf("Error growing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+
+   /* use the number */
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\chapter{Basic Operations}
+\section{Small Constants}
+Setting mp\_ints to small constants is a relatively common operation.  To accomodate these instances there are two
+small constant assignment functions.  The first function is used to set a single digit constant while the second sets
+an ISO C style ``unsigned long'' constant.  The reason for both functions is efficiency.  Setting a single digit is quick but the
+domain of a digit can change (it's always at least $0 \ldots 127$).  
+
+\subsection{Single Digit}
+
+Setting a single digit can be accomplished with the following function.
+
+\index{mp\_set}
+\begin{alltt}
+void mp_set (mp_int * a, mp_digit b);
+\end{alltt}
+
+This will zero the contents of $a$ and make it represent an integer equal to the value of $b$.  Note that this
+function has a return type of \textbf{void}.  It cannot cause an error so it is safe to assume the function
+succeeded.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 5 */
+   mp_set(&number, 5);
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Long Constants}
+
+To set a constant that is the size of an ISO C ``unsigned long'' and larger than a single digit the following function 
+can be used.
+
+\index{mp\_set\_int}
+\begin{alltt}
+int mp_set_int (mp_int * a, unsigned long b);
+\end{alltt}
+
+This will assign the value of the 32-bit variable $b$ to the mp\_int $a$.  Unlike mp\_set() this function will always
+accept a 32-bit input regardless of the size of a single digit.  However, since the value may span several digits 
+this function can fail if it runs out of heap memory.
+
+To get the ``unsigned long'' copy of an mp\_int the following function can be used.
+
+\index{mp\_get\_int}
+\begin{alltt}
+unsigned long mp_get_int (mp_int * a);
+\end{alltt}
+
+This will return the 32 least significant bits of the mp\_int $a$.  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 654321 (note this is bigger than 127) */
+   if ((result = mp_set_int(&number, 654321)) != MP_OKAY) \{
+      printf("Error setting the value of the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   printf("number == \%lu", mp_get_int(&number));
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+This should output the following if the program succeeds.
+
+\begin{alltt}
+number == 654321
+\end{alltt}
+
+\subsection{Initialize and Setting Constants}
+To both initialize and set small constants the following two functions are available.
+\index{mp\_init\_set} \index{mp\_init\_set\_int}
+\begin{alltt}
+int mp_init_set (mp_int * a, mp_digit b);
+int mp_init_set_int (mp_int * a, unsigned long b);
+\end{alltt}
+
+Both functions work like the previous counterparts except they first mp\_init $a$ before setting the values.  
+
+\begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int    result;
+
+   /* initialize and set a single digit */
+   if ((result = mp_init_set(&number1, 100)) != MP_OKAY) \{
+      printf("Error setting number1: \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}             
+
+   /* initialize and set a long */
+   if ((result = mp_init_set_int(&number2, 1023)) != MP_OKAY) \{
+      printf("Error setting number2: \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* display */
+   printf("Number1, Number2 == \%lu, \%lu",
+          mp_get_int(&number1), mp_get_int(&number2));
+
+   /* clear */
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt}
+
+If this program succeeds it shall output.
+\begin{alltt}
+Number1, Number2 == 100, 1023
+\end{alltt}
+
+\section{Comparisons}
+
+Comparisons in LibTomMath are always performed in a ``left to right'' fashion.  There are three possible return codes
+for any comparison.
+
+\index{MP\_GT} \index{MP\_EQ} \index{MP\_LT}
+\begin{figure}[here]
+\begin{center}
+\begin{tabular}{|c|c|}
+\hline \textbf{Result Code} & \textbf{Meaning} \\
+\hline MP\_GT & $a > b$ \\
+\hline MP\_EQ & $a = b$ \\
+\hline MP\_LT & $a < b$ \\
+\hline
+\end{tabular}
+\end{center}
+\caption{Comparison Codes for $a, b$}
+\label{fig:CMP}
+\end{figure}
+
+In figure \ref{fig:CMP} two integers $a$ and $b$ are being compared.  In this case $a$ is said to be ``to the left'' of 
+$b$.  
+
+\subsection{Unsigned comparison}
+
+An unsigned comparison considers only the digits themselves and not the associated \textit{sign} flag of the 
+mp\_int structures.  This is analogous to an absolute comparison.  The function mp\_cmp\_mag() will compare two
+mp\_int variables based on their digits only. 
+
+\index{mp\_cmp\_mag}
+\begin{alltt}
+int mp_cmp_mag(mp_int * a, mp_int * b);
+\end{alltt}
+This will compare $a$ to $b$ placing $a$ to the left of $b$.  This function cannot fail and will return one of the
+three compare codes listed in figure \ref{fig:CMP}.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int result;
+
+   if ((result = mp_init_multi(&number1, &number2, NULL)) != MP_OKAY) \{
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number1 to 5 */
+   mp_set(&number1, 5);
+  
+   /* set the number2 to -6 */
+   mp_set(&number2, 6);
+   if ((result = mp_neg(&number2, &number2)) != MP_OKAY) \{
+      printf("Error negating number2.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   switch(mp_cmp_mag(&number1, &number2)) \{
+       case MP_GT:  printf("|number1| > |number2|"); break;
+       case MP_EQ:  printf("|number1| = |number2|"); break;
+       case MP_LT:  printf("|number1| < |number2|"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program\footnote{This function uses the mp\_neg() function which is discussed in section \ref{sec:NEG}.} completes 
+successfully it should print the following.
+
+\begin{alltt}
+|number1| < |number2|
+\end{alltt}
+
+This is because $\vert -6 \vert = 6$ and obviously $5 < 6$.
+
+\subsection{Signed comparison}
+
+To compare two mp\_int variables based on their signed value the mp\_cmp() function is provided.
+
+\index{mp\_cmp}
+\begin{alltt}
+int mp_cmp(mp_int * a, mp_int * b);
+\end{alltt}
+
+This will compare $a$ to the left of $b$.  It will first compare the signs of the two mp\_int variables.  If they
+differ it will return immediately based on their signs.  If the signs are equal then it will compare the digits
+individually.  This function will return one of the compare conditions codes listed in figure \ref{fig:CMP}.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int result;
+
+   if ((result = mp_init_multi(&number1, &number2, NULL)) != MP_OKAY) \{
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number1 to 5 */
+   mp_set(&number1, 5);
+  
+   /* set the number2 to -6 */
+   mp_set(&number2, 6);
+   if ((result = mp_neg(&number2, &number2)) != MP_OKAY) \{
+      printf("Error negating number2.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   switch(mp_cmp(&number1, &number2)) \{
+       case MP_GT:  printf("number1 > number2"); break;
+       case MP_EQ:  printf("number1 = number2"); break;
+       case MP_LT:  printf("number1 < number2"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program\footnote{This function uses the mp\_neg() function which is discussed in section \ref{sec:NEG}.} completes 
+successfully it should print the following.
+
+\begin{alltt}
+number1 > number2
+\end{alltt}
+
+\subsection{Single Digit}
+
+To compare a single digit against an mp\_int the following function has been provided.
+
+\index{mp\_cmp\_d}
+\begin{alltt}
+int mp_cmp_d(mp_int * a, mp_digit b);
+\end{alltt}
+
+This will compare $a$ to the left of $b$ using a signed comparison.  Note that it will always treat $b$ as 
+positive.  This function is rather handy when you have to compare against small values such as $1$ (which often
+comes up in cryptography).  The function cannot fail and will return one of the tree compare condition codes
+listed in figure \ref{fig:CMP}.
+
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 5 */
+   mp_set(&number, 5);
+
+   switch(mp_cmp_d(&number, 7)) \{
+       case MP_GT:  printf("number > 7"); break;
+       case MP_EQ:  printf("number = 7"); break;
+       case MP_LT:  printf("number < 7"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program functions properly it will print out the following.
+
+\begin{alltt}
+number < 7
+\end{alltt}
+
+\section{Logical Operations}
+
+Logical operations are operations that can be performed either with simple shifts or boolean operators such as
+AND, XOR and OR directly.  These operations are very quick.
+
+\subsection{Multiplication by two}
+
+Multiplications and divisions by any power of two can be performed with quick logical shifts either left or
+right depending on the operation.  
+
+When multiplying or dividing by two a special case routine can be used which are as follows.
+\index{mp\_mul\_2} \index{mp\_div\_2}
+\begin{alltt}
+int mp_mul_2(mp_int * a, mp_int * b);
+int mp_div_2(mp_int * a, mp_int * b);
+\end{alltt}
+
+The former will assign twice $a$ to $b$ while the latter will assign half $a$ to $b$.  These functions are fast
+since the shift counts and maskes are hardcoded into the routines.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 5 */
+   mp_set(&number, 5);
+
+   /* multiply by two */
+   if ((result = mp\_mul\_2(&number, &number)) != MP_OKAY) \{
+      printf("Error multiplying the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   switch(mp_cmp_d(&number, 7)) \{
+       case MP_GT:  printf("2*number > 7"); break;
+       case MP_EQ:  printf("2*number = 7"); break;
+       case MP_LT:  printf("2*number < 7"); break;
+   \}
+
+   /* now divide by two */
+   if ((result = mp\_div\_2(&number, &number)) != MP_OKAY) \{
+      printf("Error dividing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   switch(mp_cmp_d(&number, 7)) \{
+       case MP_GT:  printf("2*number/2 > 7"); break;
+       case MP_EQ:  printf("2*number/2 = 7"); break;
+       case MP_LT:  printf("2*number/2 < 7"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program is successful it will print out the following text.
+
+\begin{alltt}
+2*number > 7
+2*number/2 < 7
+\end{alltt}
+
+Since $10 > 7$ and $5 < 7$.  To multiply by a power of two the following function can be used.
+
+\index{mp\_mul\_2d}
+\begin{alltt}
+int mp_mul_2d(mp_int * a, int b, mp_int * c);
+\end{alltt}
+
+This will multiply $a$ by $2^b$ and store the result in ``c''.  If the value of $b$ is less than or equal to 
+zero the function will copy $a$ to ``c'' without performing any further actions.  
+
+To divide by a power of two use the following.
+
+\index{mp\_div\_2d}
+\begin{alltt}
+int mp_div_2d (mp_int * a, int b, mp_int * c, mp_int * d);
+\end{alltt}
+Which will divide $a$ by $2^b$, store the quotient in ``c'' and the remainder in ``d'.  If $b \le 0$ then the
+function simply copies $a$ over to ``c'' and zeroes $d$.  The variable $d$ may be passed as a \textbf{NULL}
+value to signal that the remainder is not desired.
+
+\subsection{Polynomial Basis Operations}
+
+Strictly speaking the organization of the integers within the mp\_int structures is what is known as a 
+``polynomial basis''.  This simply means a field element is stored by divisions of a radix.  For example, if
+$f(x) = \sum_{i=0}^{k} y_ix^k$ for any vector $\vec y$ then the array of digits in $\vec y$ are said to be 
+the polynomial basis representation of $z$ if $f(\beta) = z$ for a given radix $\beta$.  
+
+To multiply by the polynomial $g(x) = x$ all you have todo is shift the digits of the basis left one place.  The
+following function provides this operation.
+
+\index{mp\_lshd}
+\begin{alltt}
+int mp_lshd (mp_int * a, int b);
+\end{alltt}
+
+This will multiply $a$ in place by $x^b$ which is equivalent to shifting the digits left $b$ places and inserting zeroes
+in the least significant digits.  Similarly to divide by a power of $x$ the following function is provided.
+
+\index{mp\_rshd}
+\begin{alltt}
+void mp_rshd (mp_int * a, int b)
+\end{alltt}
+This will divide $a$ in place by $x^b$ and discard the remainder.  This function cannot fail as it performs the operations
+in place and no new digits are required to complete it.
+
+\subsection{AND, OR and XOR Operations}
+
+While AND, OR and XOR operations are not typical ``bignum functions'' they can be useful in several instances.  The
+three functions are prototyped as follows.
+
+\index{mp\_or} \index{mp\_and} \index{mp\_xor}
+\begin{alltt}
+int mp_or  (mp_int * a, mp_int * b, mp_int * c);
+int mp_and (mp_int * a, mp_int * b, mp_int * c);
+int mp_xor (mp_int * a, mp_int * b, mp_int * c);
+\end{alltt}
+
+Which compute $c = a \odot b$ where $\odot$ is one of OR, AND or XOR.  
+
+\section{Addition and Subtraction}
+
+To compute an addition or subtraction the following two functions can be used.
+
+\index{mp\_add} \index{mp\_sub}
+\begin{alltt}
+int mp_add (mp_int * a, mp_int * b, mp_int * c);
+int mp_sub (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+
+Which perform $c = a \odot b$ where $\odot$ is one of signed addition or subtraction.  The operations are fully sign
+aware.
+
+\section{Sign Manipulation}
+\subsection{Negation}
+\label{sec:NEG}
+Simple integer negation can be performed with the following.
+
+\index{mp\_neg}
+\begin{alltt}
+int mp_neg (mp_int * a, mp_int * b);
+\end{alltt}
+
+Which assigns $-a$ to $b$.  
+
+\subsection{Absolute}
+Simple integer absolutes can be performed with the following.
+
+\index{mp\_neg}
+\begin{alltt}
+int mp_abs (mp_int * a, mp_int * b);
+\end{alltt}
+
+Which assigns $\vert a \vert$ to $b$.  
+
+\section{Integer Division and Remainder}
+To perform a complete and general integer division with remainder use the following function.
+
+\index{mp\_div}
+\begin{alltt}
+int mp_div (mp_int * a, mp_int * b, mp_int * c, mp_int * d);
+\end{alltt}
+                                                        
+This divides $a$ by $b$ and stores the quotient in $c$ and $d$.  The signed quotient is computed such that 
+$bc + d = a$.  Note that either of $c$ or $d$ can be set to \textbf{NULL} if their value is not required.  If 
+$b$ is zero the function returns \textbf{MP\_VAL}.  
+
+
+\chapter{Multiplication and Squaring}
+\section{Multiplication}
+A full signed integer multiplication can be performed with the following.
+\index{mp\_mul}
+\begin{alltt}
+int mp_mul (mp_int * a, mp_int * b, mp_int * c);
+\end{alltt}
+Which assigns the full signed product $ab$ to $c$.  This function actually breaks into one of four cases which are 
+specific multiplication routines optimized for given parameters.  First there are the Toom-Cook multiplications which
+should only be used with very large inputs.  This is followed by the Karatsuba multiplications which are for moderate
+sized inputs.  Then followed by the Comba and baseline multipliers.
+
+Fortunately for the developer you don't really need to know this unless you really want to fine tune the system.  mp\_mul()
+will determine on its own\footnote{Some tweaking may be required.} what routine to use automatically when it is called.
+
+\begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int result;
+
+   /* Initialize the numbers */
+   if ((result = mp_init_multi(&number1, 
+                               &number2, NULL)) != MP_OKAY) \{
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* set the terms */
+   if ((result = mp_set_int(&number, 257)) != MP_OKAY) \{
+      printf("Error setting number1.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   if ((result = mp_set_int(&number2, 1023)) != MP_OKAY) \{
+      printf("Error setting number2.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* multiply them */
+   if ((result = mp_mul(&number1, &number2,
+                        &number1)) != MP_OKAY) \{
+      printf("Error multiplying terms.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* display */
+   printf("number1 * number2 == \%lu", mp_get_int(&number1));
+
+   /* free terms and return */
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt}   
+
+If this program succeeds it shall output the following.
+
+\begin{alltt}
+number1 * number2 == 262911
+\end{alltt}
+
+\section{Squaring}
+Since squaring can be performed faster than multiplication it is performed it's own function instead of just using
+mp\_mul().
+
+\index{mp\_sqr}
+\begin{alltt}
+int mp_sqr (mp_int * a, mp_int * b);
+\end{alltt}
+
+Will square $a$ and store it in $b$.  Like the case of multiplication there are four different squaring
+algorithms all which can be called from mp\_sqr().  It is ideal to use mp\_sqr over mp\_mul when squaring terms because
+of the speed difference.  
+
+\section{Tuning Polynomial Basis Routines}
+
+Both of the Toom-Cook and Karatsuba multiplication algorithms are faster than the traditional $O(n^2)$ approach that
+the Comba and baseline algorithms use.  At $O(n^{1.464973})$ and $O(n^{1.584962})$ running times respectively they require 
+considerably less work.  For example, a 10000-digit multiplication would take roughly 724,000 single precision
+multiplications with Toom-Cook or 100,000,000 single precision multiplications with the standard Comba (a factor
+of 138).
+
+So why not always use Karatsuba or Toom-Cook?   The simple answer is that they have so much overhead that they're not
+actually faster than Comba until you hit distinct  ``cutoff'' points.  For Karatsuba with the default configuration, 
+GCC 3.3.1 and an Athlon XP processor the cutoff point is roughly 110 digits (about 70 for the Intel P4).  That is, at 
+110 digits Karatsuba and Comba multiplications just about break even and for 110+ digits Karatsuba is faster.
+
+Toom-Cook has incredible overhead and is probably only useful for very large inputs.  So far no known cutoff points 
+exist and for the most part I just set the cutoff points very high to make sure they're not called.
+
+A demo program in the ``etc/'' directory of the project called ``tune.c'' can be used to find the cutoff points.  This
+can be built with GCC as follows
+
+\begin{alltt}
+make XXX
+\end{alltt}
+Where ``XXX'' is one of the following entries from the table \ref{fig:tuning}.
+
+\begin{figure}[here]
+\begin{center}
+\begin{small}
+\begin{tabular}{|l|l|}
+\hline \textbf{Value of XXX} & \textbf{Meaning} \\
+\hline tune & Builds portable tuning application \\
+\hline tune86 & Builds x86 (pentium and up) program for COFF \\
+\hline tune86c & Builds x86 program for Cygwin \\
+\hline tune86l & Builds x86 program for Linux (ELF format) \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{Build Names for Tuning Programs}
+\label{fig:tuning}
+\end{figure}
+
+When the program is running it will output a series of measurements for different cutoff points.  It will first find
+good Karatsuba squaring and multiplication points.  Then it proceeds to find Toom-Cook points.  Note that the Toom-Cook
+tuning takes a very long time as the cutoff points are likely to be very high.
+
+\chapter{Modular Reduction}
+
+Modular reduction is process of taking the remainder of one quantity divided by another.  Expressed 
+as (\ref{eqn:mod}) the modular reduction is equivalent to the remainder of $b$ divided by $c$.  
+
+\begin{equation}
+a \equiv b \mbox{ (mod }c\mbox{)}
+\label{eqn:mod}
+\end{equation}
+
+Of particular interest to cryptography are reductions where $b$ is limited to the range $0 \le b < c^2$ since particularly 
+fast reduction algorithms can be written for the limited range.  
+
+Note that one of the four optimized reduction algorithms are automatically chosen in the modular exponentiation
+algorithm mp\_exptmod when an appropriate modulus is detected.  
+
+\section{Straight Division}
+In order to effect an arbitrary modular reduction the following algorithm is provided.
+
+\index{mp\_mod}
+\begin{alltt}
+int mp_mod(mp_int *a, mp_int *b, mp_int *c);
+\end{alltt}
+
+This reduces $a$ modulo $b$ and stores the result in $c$.  The sign of $c$ shall agree with the sign 
+of $b$.  This algorithm accepts an input $a$ of any range and is not limited by $0 \le a < b^2$.
+
+\section{Barrett Reduction}
+
+Barrett reduction is a generic optimized reduction algorithm that requires pre--computation to achieve
+a decent speedup over straight division.  First a $\mu$ value must be precomputed with the following function.
+
+\index{mp\_reduce\_setup}
+\begin{alltt}
+int mp_reduce_setup(mp_int *a, mp_int *b);
+\end{alltt}
+
+Given a modulus in $b$ this produces the required $\mu$ value in $a$.  For any given modulus this only has to
+be computed once.  Modular reduction can now be performed with the following.
+
+\index{mp\_reduce}
+\begin{alltt}
+int mp_reduce(mp_int *a, mp_int *b, mp_int *c);
+\end{alltt}
+
+This will reduce $a$ in place modulo $b$ with the precomputed $\mu$ value in $c$.  $a$ must be in the range
+$0 \le a < b^2$.

+      return EXIT_FAILURE;
+   \}
+

+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} 
+
+This program will calculate $a^3 \mbox{ mod }b$ if all the functions succeed.  
+
+\section{Montgomery Reduction}
+
+Montgomery is a specialized reduction algorithm for any odd moduli.  Like Barrett reduction a pre--computation
+step is required.  This is accomplished with the following.
+
+\index{mp\_montgomery\_setup}
+\begin{alltt}
+int mp_montgomery_setup(mp_int *a, mp_digit *mp);
+\end{alltt}
+
+For the given odd moduli $a$ the precomputation value is placed in $mp$.  The reduction is computed with the 
+following.
+
+\index{mp\_montgomery\_reduce}
+\begin{alltt}
+int mp_montgomery_reduce(mp_int *a, mp_int *m, mp_digit mp);
+\end{alltt}
+This reduces $a$ in place modulo $m$ with the pre--computed value $mp$.   $a$ must be in the range
+$0 \le a < b^2$.
+
+Montgomery reduction is faster than Barrett reduction for moduli smaller than the ``comba'' limit.  With the default
+setup for instance, the limit is $127$ digits ($3556$--bits).   Note that this function is not limited to
+$127$ digits just that it falls back to a baseline algorithm after that point.  
+
+An important observation is that this reduction does not return $a \mbox{ mod }m$ but $aR^{-1} \mbox{ mod }m$ 
+where $R = \beta^n$, $n$ is the n number of digits in $m$ and $\beta$ is radix used (default is $2^{28}$).  
+
+To quickly calculate $R$ the following function was provided.
+
+\index{mp\_montgomery\_calc\_normalization}
+\begin{alltt}
+int mp_montgomery_calc_normalization(mp_int *a, mp_int *b);
+\end{alltt}
+Which calculates $a = R$ for the odd moduli $b$ without using multiplication or division.  
+
+The normal modus operandi for Montgomery reductions is to normalize the integers before entering the system.  For
+example, to calculate $a^3 \mbox { mod }b$ using Montgomery reduction the value of $a$ can be normalized by
+multiplying it by $R$.  Consider the following code snippet.
+
+\begin{alltt}
+int main(void)
+\{
+   mp_int   a, b, c, R;
+   mp_digit mp;
+   int      result;
+
+   /* initialize a,b to desired values, 
+    * mp_init R, c and set c to 1.... 
+    */
+
+   /* get normalization */
+   if ((result = mp_montgomery_calc_normalization(&R, b)) != MP_OKAY) \{
+      printf("Error getting norm.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* get mp value */
+   if ((result = mp_montgomery_setup(&c, &mp)) != MP_OKAY) \{
+      printf("Error setting up montgomery.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* normalize `a' so now a is equal to aR */
+   if ((result = mp_mulmod(&a, &R, &b, &a)) != MP_OKAY) \{
+      printf("Error computing aR.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* square a to get c = a^2R^2 */
+   if ((result = mp_sqr(&a, &c)) != MP_OKAY) \{
+      printf("Error squaring.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* now reduce `c' back down to c = a^2R^2 * R^-1 == a^2R */
+   if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   
+   /* multiply a to get c = a^3R^2 */
+   if ((result = mp_mul(&a, &c, &c)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* now reduce `c' back down to c = a^3R^2 * R^-1 == a^3R */
+   if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   
+   /* now reduce (again) `c' back down to c = a^3R * R^-1 == a^3 */
+   if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* c now equals a^3 mod b */
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} 
+
+This particular example does not look too efficient but it demonstrates the point of the algorithm.  By 
+normalizing the inputs the reduced results are always of the form $aR$ for some variable $a$.  This allows
+a single final reduction to correct for the normalization and the fast reduction used within the algorithm.
+
+For more details consider examining the file \textit{bn\_mp\_exptmod\_fast.c}.
+
+\section{Restricted Dimminished Radix}
+
+``Dimminished Radix'' reduction refers to reduction with respect to moduli that are ameniable to simple
+digit shifting and small multiplications.  In this case the ``restricted'' variant refers to moduli of the
+form $\beta^k - p$ for some $k \ge 0$ and $0 < p < \beta$ where $\beta$ is the radix (default to $2^{28}$).  
+
+As in the case of Montgomery reduction there is a pre--computation phase required for a given modulus.
+
+\index{mp\_dr\_setup}
+\begin{alltt}
+void mp_dr_setup(mp_int *a, mp_digit *d);
+\end{alltt}
+
+This computes the value required for the modulus $a$ and stores it in $d$.  This function cannot fail
+and does not return any error codes.  After the pre--computation a reduction can be performed with the
+following.
+
+\index{mp\_dr\_reduce}
+\begin{alltt}
+int mp_dr_reduce(mp_int *a, mp_int *b, mp_digit mp);
+\end{alltt}
+
+This reduces $a$ in place modulo $b$ with the pre--computed value $mp$.  $b$ must be of a restricted
+dimminished radix form and $a$ must be in the range $0 \le a < b^2$.  Dimminished radix reductions are 
+much faster than both Barrett and Montgomery reductions as they have a much lower asymtotic running time.  
+
+Since the moduli are restricted this algorithm is not particularly useful for something like Rabin, RSA or
+BBS cryptographic purposes.  This reduction algorithm is useful for Diffie-Hellman and ECC where fixed
+primes are acceptable.  
+
+Note that unlike Montgomery reduction there is no normalization process.  The result of this function is
+equal to the correct residue.
+
+\section{Unrestricted Dimminshed Radix}
+
+Unrestricted reductions work much like the restricted counterparts except in this case the moduli is of the 
+form $2^k - p$ for $0 < p < \beta$.  In this sense the unrestricted reductions are more flexible as they 
+can be applied to a wider range of numbers.  
+
+\index{mp\_reduce\_2k\_setup}
+\begin{alltt}
+int mp_reduce_2k_setup(mp_int *a, mp_digit *d);
+\end{alltt}
+
+This will compute the required $d$ value for the given moduli $a$.  
+
+\index{mp\_reduce\_2k}
+\begin{alltt}
+int mp_reduce_2k(mp_int *a, mp_int *n, mp_digit d);
+\end{alltt}
+
+This will reduce $a$ in place modulo $n$ with the pre--computed value $d$.  From my experience this routine is 
+slower than mp\_dr\_reduce but faster for most moduli sizes than the Montgomery reduction.  
+
+\chapter{Exponentiation}
+\section{Single Digit Exponentiation}
+\index{mp\_expt\_d}
+\begin{alltt}
+int mp_expt_d (mp_int * a, mp_digit b, mp_int * c)
+\end{alltt}
+This computes $c = a^b$ using a simple binary left-to-right algorithm.  It is faster than repeated multiplications by 
+$a$ for all values of $b$ greater than three.  
+
+\section{Modular Exponentiation}
+\index{mp\_exptmod}
+\begin{alltt}
+int mp_exptmod (mp_int * G, mp_int * X, mp_int * P, mp_int * Y)
+\end{alltt}
+This computes $Y \equiv G^X \mbox{ (mod }P\mbox{)}$ using a variable width sliding window algorithm.  This function
+will automatically detect the fastest modular reduction technique to use during the operation.  For negative values of 
+$X$ the operation is performed as $Y \equiv (G^{-1} \mbox{ mod }P)^{\vert X \vert} \mbox{ (mod }P\mbox{)}$ provided that 
+$gcd(G, P) = 1$.
+
+This function is actually a shell around the two internal exponentiation functions.  This routine will automatically
+detect when Barrett, Montgomery, Restricted and Unrestricted Dimminished Radix based exponentiation can be used.  Generally
+moduli of the a ``restricted dimminished radix'' form lead to the fastest modular exponentiations.  Followed by Montgomery
+and the other two algorithms.
+
+\section{Root Finding}
+\index{mp\_n\_root}
+\begin{alltt}
+int mp_n_root (mp_int * a, mp_digit b, mp_int * c)
+\end{alltt}
+This computes $c = a^{1/b}$ such that $c^b \le a$ and $(c+1)^b > a$.  The implementation of this function is not 
+ideal for values of $b$ greater than three.  It will work but become very slow.  So unless you are working with very small
+numbers (less than 1000 bits) I'd avoid $b > 3$ situations.  Will return a positive root only for even roots and return
+a root with the sign of the input for odd roots.  For example, performing $4^{1/2}$ will return $2$ whereas $(-8)^{1/3}$ 
+will return $-2$.  
+
+This algorithm uses the ``Newton Approximation'' method and will converge on the correct root fairly quickly.  Since
+the algorithm requires raising $a$ to the power of $b$ it is not ideal to attempt to find roots for large
+values of $b$.  If particularly large roots are required then a factor method could be used instead.  For example,
+$a^{1/16}$ is equivalent to $\left (a^{1/4} \right)^{1/4}$ or simply 
+$\left ( \left ( \left ( a^{1/2} \right )^{1/2} \right )^{1/2} \right )^{1/2}$
+
+\chapter{Prime Numbers}
+\section{Trial Division}
+\index{mp\_prime\_is\_divisible}
+\begin{alltt}
+int mp_prime_is_divisible (mp_int * a, int *result)
+\end{alltt}
+This will attempt to evenly divide $a$ by a list of primes\footnote{Default is the first 256 primes.} and store the 
+outcome in ``result''.  That is if $result = 0$ then $a$ is not divisible by the primes, otherwise it is.  Note that 
+if the function does not return \textbf{MP\_OKAY} the value in ``result'' should be considered undefined\footnote{Currently
+the default is to set it to zero first.}.
+
+\section{Fermat Test}
+\index{mp\_prime\_fermat}
+\begin{alltt}
+int mp_prime_fermat (mp_int * a, mp_int * b, int *result)
+\end{alltt}
+Performs a Fermat primality test to the base $b$.  That is it computes $b^a \mbox{ mod }a$ and tests whether the value is
+equal to $b$ or not.  If the values are equal then $a$ is probably prime and $result$ is set to one.  Otherwise $result$
+is set to zero.
+
+\section{Miller-Rabin Test}
+\index{mp\_prime\_miller\_rabin}
+\begin{alltt}
+int mp_prime_miller_rabin (mp_int * a, mp_int * b, int *result)
+\end{alltt}
+Performs a Miller-Rabin test to the base $b$ of $a$.  This test is much stronger than the Fermat test and is very hard to
+fool (besides with Carmichael numbers).  If $a$ passes the test (therefore is probably prime) $result$ is set to one.  
+Otherwise $result$ is set to zero.  
+
+Note that is suggested that you use the Miller-Rabin test instead of the Fermat test since all of the failures of 
+Miller-Rabin are a subset of the failures of the Fermat test.
+
+\subsection{Required Number of Tests}
+Generally to ensure a number is very likely to be prime you have to perform the Miller-Rabin with at least a half-dozen
+or so unique bases.  However, it has been proven that the probability of failure goes down as the size of the input goes up.
+This is why a simple function has been provided to help out.
+
+\index{mp\_prime\_rabin\_miller\_trials}
+\begin{alltt}
+int mp_prime_rabin_miller_trials(int size)
+\end{alltt}
+This returns the number of trials required for a $2^{-96}$ (or lower) probability of failure for a given ``size'' expressed
+in bits.  This comes in handy specially since larger numbers are slower to test.  For example, a 512-bit number would
+require ten tests whereas a 1024-bit number would only require four tests. 
+
+You should always still perform a trial division before a Miller-Rabin test though.
+
+\section{Primality Testing}
+\index{mp\_prime\_is\_prime}
+\begin{alltt}
+int mp_prime_is_prime (mp_int * a, int t, int *result)
+\end{alltt}
+This will perform a trial division followed by $t$ rounds of Miller-Rabin tests on $a$ and store the result in $result$.  
+If $a$ passes all of the tests $result$ is set to one, otherwise it is set to zero.  Note that $t$ is bounded by 
+$1 \le t < PRIME\_SIZE$ where $PRIME\_SIZE$ is the number of primes in the prime number table (by default this is $256$).
+
+\section{Next Prime}
+\index{mp\_prime\_next\_prime}
+\begin{alltt}
+int mp_prime_next_prime(mp_int *a, int t, int bbs_style)
+\end{alltt}
+This finds the next prime after $a$ that passes mp\_prime\_is\_prime() with $t$ tests.  Set $bbs\_style$ to one if you 
+want only the next prime congruent to $3 \mbox{ mod } 4$, otherwise set it to zero to find any next prime.  
+
+\section{Random Primes}
+\index{mp\_prime\_random}
+\begin{alltt}
+int mp_prime_random(mp_int *a, int t, int size, int bbs, 
+                    ltm_prime_callback cb, void *dat)
+\end{alltt}
+This will find a prime greater than $256^{size}$ which can be ``bbs\_style'' or not depending on $bbs$ and must pass
+$t$ rounds of tests.  The ``ltm\_prime\_callback'' is a typedef for 
+
+\begin{alltt}
+typedef int ltm_prime_callback(unsigned char *dst, int len, void *dat);
+\end{alltt}
+
+Which is a function that must read $len$ bytes (and return the amount stored) into $dst$.  The $dat$ variable is simply
+copied from the original input.  It can be used to pass RNG context data to the callback.  The function 
+mp\_prime\_random() is more suitable for generating primes which must be secret (as in the case of RSA) since there 
+is no skew on the least significant bits.
+
+\textit{Note:}  As of v0.30 of the LibTomMath library this function has been deprecated.  It is still available
+but users are encouraged to use the new mp\_prime\_random\_ex() function instead.
+
+\subsection{Extended Generation}
+\index{mp\_prime\_random\_ex}
+\begin{alltt}
+int mp_prime_random_ex(mp_int *a,    int t, 
+                       int     size, int flags, 
+                       ltm_prime_callback cb, void *dat);
+\end{alltt}
+This will generate a prime in $a$ using $t$ tests of the primality testing algorithms.  The variable $size$
+specifies the bit length of the prime desired.  The variable $flags$ specifies one of several options available
+(see fig. \ref{fig:primeopts}) which can be OR'ed together.  The callback parameters are used as in 
+mp\_prime\_random().
+

+\section{ASCII Conversions}
+\subsection{To ASCII}
+\index{mp\_toradix}
+\begin{alltt}
+int mp_toradix (mp_int * a, char *str, int radix);
+\end{alltt}
+This still store $a$ in ``str'' as a base-``radix'' string of ASCII chars.  This function appends a NUL character
+to terminate the string.  Valid values of ``radix'' line in the range $[2, 64]$.  To determine the size (exact) required
+by the conversion before storing any data use the following function.
+
+\index{mp\_radix\_size}
+\begin{alltt}
+int mp_radix_size (mp_int * a, int radix, int *size)
+\end{alltt}
+This stores in ``size'' the number of characters (including space for the NUL terminator) required.  Upon error this 
+function returns an error code and ``size'' will be zero.  
+
+\subsection{From ASCII}
+\index{mp\_read\_radix}
+\begin{alltt}
+int mp_read_radix (mp_int * a, char *str, int radix);
+\end{alltt}
+This will read the base-``radix'' NUL terminated string from ``str'' into $a$.  It will stop reading when it reads a
+character it does not recognize (which happens to include th NUL char... imagine that...).  A single leading $-$ sign
+can be used to denote a negative number.
+
+\section{Binary Conversions}
+
+Converting an mp\_int to and from binary is another keen idea.
+
+\index{mp\_unsigned\_bin\_size}
+\begin{alltt}
+int mp_unsigned_bin_size(mp_int *a);
+\end{alltt}
+
+This will return the number of bytes (octets) required to store the unsigned copy of the integer $a$.
+
+\index{mp\_to\_unsigned\_bin}
+\begin{alltt}
+int mp_to_unsigned_bin(mp_int *a, unsigned char *b);
+\end{alltt}
+This will store $a$ into the buffer $b$ in big--endian format.  Fortunately this is exactly what DER (or is it ASN?)
+requires.  It does not store the sign of the integer.
+
+\index{mp\_read\_unsigned\_bin}
+\begin{alltt}
+int mp_read_unsigned_bin(mp_int *a, unsigned char *b, int c);
+\end{alltt}
+This will read in an unsigned big--endian array of bytes (octets) from $b$ of length $c$ into $a$.  The resulting
+integer $a$ will always be positive.
+
+For those who acknowledge the existence of negative numbers (heretic!) there are ``signed'' versions of the
+previous functions.
+
+\begin{alltt}
+int mp_signed_bin_size(mp_int *a);
+int mp_read_signed_bin(mp_int *a, unsigned char *b, int c);
+int mp_to_signed_bin(mp_int *a, unsigned char *b);
+\end{alltt}
+They operate essentially the same as the unsigned copies except they prefix the data with zero or non--zero
+byte depending on the sign.  If the sign is zpos (e.g. not negative) the prefix is zero, otherwise the prefix
+is non--zero.  
+
+\chapter{Algebraic Functions}
+\section{Extended Euclidean Algorithm}
+\index{mp\_exteuclid}

+int mp_exteuclid(mp_int *a, mp_int *b, 
+                 mp_int *U1, mp_int *U2, mp_int *U3);
+\end{alltt}
+
+This finds the triple U1/U2/U3 using the Extended Euclidean algorithm such that the following equation holds.
+
+\begin{equation}
+a \cdot U1 + b \cdot U2 = U3
+\end{equation}
+
+Any of the U1/U2/U3 paramters can be set to \textbf{NULL} if they are not desired.  
+
+\section{Greatest Common Divisor}
+\index{mp\_gcd}
+\begin{alltt}
+int mp_gcd (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+This will compute the greatest common divisor of $a$ and $b$ and store it in $c$.
+
+\section{Least Common Multiple}
+\index{mp\_lcm}
+\begin{alltt}
+int mp_lcm (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+This will compute the least common multiple of $a$ and $b$ and store it in $c$.
+
+\section{Jacobi Symbol}
+\index{mp\_jacobi}
+\begin{alltt}
+int mp_jacobi (mp_int * a, mp_int * p, int *c)
+\end{alltt}
+This will compute the Jacobi symbol for $a$ with respect to $p$.  If $p$ is prime this essentially computes the Legendre
+symbol.  The result is stored in $c$ and can take on one of three values $\lbrace -1, 0, 1 \rbrace$.  If $p$ is prime
+then the result will be $-1$ when $a$ is not a quadratic residue modulo $p$.  The result will be $0$ if $a$ divides $p$
+and the result will be $1$ if $a$ is a quadratic residue modulo $p$.  
+
+\section{Modular Inverse}
+\index{mp\_invmod}
+\begin{alltt}
+int mp_invmod (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+Computes the multiplicative inverse of $a$ modulo $b$ and stores the result in $c$ such that $ac \equiv 1 \mbox{ (mod }b\mbox{)}$.
+
+\section{Single Digit Functions}
+
+For those using small numbers (\textit{snicker snicker}) there are several ``helper'' functions
+
+\index{mp\_add\_d} \index{mp\_sub\_d} \index{mp\_mul\_d} \index{mp\_div\_d} \index{mp\_mod\_d}
+\begin{alltt}
+int mp_add_d(mp_int *a, mp_digit b, mp_int *c);
+int mp_sub_d(mp_int *a, mp_digit b, mp_int *c);
+int mp_mul_d(mp_int *a, mp_digit b, mp_int *c);
+int mp_div_d(mp_int *a, mp_digit b, mp_int *c, mp_digit *d);
+int mp_mod_d(mp_int *a, mp_digit b, mp_digit *c);
+\end{alltt}
+
+These work like the full mp\_int capable variants except the second parameter $b$ is a mp\_digit.  These
+functions fairly handy if you have to work with relatively small numbers since you will not have to allocate
+an entire mp\_int to store a number like $1$ or $2$.

+ *
+ * Let B represent the radix [e.g. 2**DIGIT_BIT] and 
+ * let n represent half of the number of digits in 
+ * the min(a,b)
+ *
+ * a = a1 * B**n + a0

+ *
+ * Note that a1b1 and a0b0 are used twice and only need to be 
+ * computed once.  So in total three half size (half # of 
+ * digit) multiplications are performed, a0b0, a1b1 and 
+ * (a1+b1)(a0+b0)
+ *
+ * Note that a multiplication of half the digits requires
+ * 1/4th the number of single precision multiplications so in 
+ * total after one call 25% of the single precision multiplications 
+ * are saved.  Note also that the call to mp_mul can end up back 
+ * in this function if the a0, a1, b0, or b1 are above the threshold.  
+ * This is known as divide-and-conquer and leads to the famous 
+ * O(N**lg(3)) or O(N**1.584) work which is asymptopically lower than 
+ * the standard O(N**2) that the baseline/comba methods use.  
+ * Generally though the overhead of this method doesn't pay off

+       -- updated email and url info in all source files
+
+Jan 26th, 2006
+v0.38  -- broken makefile.shared fixed
+       -- removed some carry stores that were not required [updated text]
+       
+November 18th, 2005
+v0.37  -- [Don Porter] reported on a TCL list [HEY SEND ME BUGREPORTS ALREADY!!!] that mp_add_d() would compute -0 with some inputs.  Fixed.
+       -- [rinick@gmail.com] reported the makefile.bcc was messed up.  Fixed.
+       -- [Kevin Kenny] reported some issues with mp_toradix_n().  Now it doesn't require a min of 3 chars of output.  
+       -- Made the make command renamable.  Wee
+
+August 1st, 2005

+v0.35  -- Stupid XOR function missing line again... oops.
+       -- Fixed bug in invmod not handling negative inputs correctly [Wolfgang Ehrhardt]

+          Actually is faster than Montgomery on my AMD64 (and probably much faster on a P4)
+       -- Updated the manual a bit
+       -- Ok so I haven't done the textbook work yet... My current freelance gig has landed me in France till the 
+          end of Feb/05.  Once I get back I'll have tons of free time and I plan to go to town on the book.
+          As of this release the API will freeze.  At least until the book catches up with all the changes.  I welcome
+          bug reports but new algorithms will have to wait.
+
+December 23rd, 2004
+v0.33  -- Fixed "small" variant for mp_div() which would munge with negative dividends...
+       -- Fixed bug in mp_prime_random_ex() which would set the most significant byte to zero when
+          no special flags were set
+       -- Fixed overflow [minor] bug in fast_s_mp_sqr()
+       -- Made the makefiles easier to configure the group/user that ltm will install as
+       -- Fixed "final carry" bug in comba multipliers. (Volkan Ceylan)
+       -- Matt Johnston pointed out a missing semi-colon in mp_exptmod
+
+October 29th, 2004
+v0.32  -- Added "makefile.shared" for shared object support
+       -- Added more to the build options/configs in the manual
+       -- Started the Depends framework, wrote dep.pl to scan deps and 
+          produce "callgraph.txt" ;-)
+       -- Wrote SC_RSA_1 which will enable close to the minimum required to perform
+          RSA on 32-bit [or 64-bit] platforms with LibTomCrypt
+       -- Merged in the small/slower mp_div replacement.  You can now toggle which
+          you want to use as your mp_div() at build time.  Saves roughly 8KB or so.
+       -- Renamed a few files and changed some comments to make depends system work better.
+          (No changes to function names)
+       -- Merged in new Combas that perform 2 reads per inner loop instead of the older 
+          3reads/2writes per inner loop of the old code.  Really though if you want speed
+          learn to use TomsFastMath ;-)
+
+August 9th, 2004
+v0.31  -- "profiled" builds now :-) new timings for Intel Northwoods
+       -- Added "pretty" build target
+       -- Update mp_init() to actually assign 0's instead of relying on calloc()
+       -- "Wolfgang Ehrhardt" <Wolfgang.Ehrhardt@munich.netsurf.de> found a bug in mp_mul() where if
+          you multiply a negative by zero you get negative zero as the result.  Oops.
+       -- J Harper from PeerSec let me toy with his AMD64 and I got 60-bit digits working properly
+          [this also means that I fixed a bug where if sizeof(int) < sizeof(mp_digit) it would bug]
+
+April 11th, 2004
+v0.30  -- Added "mp_toradix_n" which stores upto "n-1" least significant digits of an mp_int
+       -- Johan Lindh sent a patch so MSVC wouldn't whine about redefining malloc [in weird dll modes]
+       -- Henrik Goldman spotted a missing OPT_CAST in mp_fwrite()
+       -- Tuned tommath.h so that when MP_LOW_MEM is defined MP_PREC shall be reduced.
+          [I also allow MP_PREC to be externally defined now]
+       -- Sped up mp_cnt_lsb() by using a 4x4 table [e.g. 4x speedup]
+       -- Added mp_prime_random_ex() which is a more versatile prime generator accurate to
+          exact bit lengths (unlike the deprecated but still available mp_prime_random() which
+          is only accurate to byte lengths).  See the new LTM_PRIME_* flags ;-)
+       -- Alex Polushin contributed an optimized mp_sqrt() as well as mp_get_int() and mp_is_square().
+          I've cleaned them all up to be a little more consistent [along with one bug fix] for this release.
+       -- Added mp_init_set and mp_init_set_int to initialize and set small constants with one function
+          call.
+       -- Removed /etclib directory [um LibTomPoly deprecates this].
+       -- Fixed mp_mod() so the sign of the result agrees with the sign of the modulus.
+       ++ N.B.  My semester is almost up so expect updates to the textbook to be posted to the libtomcrypt.org 
+          website.  
+
+Jan 25th, 2004
+v0.29  ++ Note: "Henrik" from the v0.28 changelog refers to Henrik Goldman ;-)
+       -- Added fix to mp_shrink to prevent a realloc when used == 0 [e.g. realloc zero bytes???]
+       -- Made the mp_prime_rabin_miller_trials() function internal table smaller and also
+          set the minimum number of tests to two (sounds a bit safer).
+       -- Added a mp_exteuclid() which computes the extended euclidean algorithm.
+       -- Fixed a memory leak in s_mp_exptmod() [called when Barrett reduction is to be used] which would arise
+          if a multiplication or subsequent reduction failed [would not free the temp result].
+       -- Made an API change to mp_radix_size().  It now returns an error code and stores the required size
+          through an "int star" passed to it.
+
+Dec 24th, 2003
+v0.28  -- Henrik Goldman suggested I add casts to the montomgery code [stores into mu...] so compilers wouldn't
+          spew [erroneous] diagnostics... fixed.
+       -- Henrik Goldman also spotted two typos.  One in mp_radix_size() and another in mp_toradix().
+       -- Added fix to mp_shrink() to avoid a memory leak.
+       -- Added mp_prime_random() which requires a callback to make truly random primes of a given nature
+          (idea from chat with Niels Ferguson at Crypto'03)
+       -- Picked up a second wind.  I'm filled with Gooo.  Mission Gooo!
+       -- Removed divisions from mp_reduce_is_2k()
+       -- Sped up mp_div_d() [general case] to use only one division per digit instead of two.
+       -- Added the heap macros from LTC to LTM.  Now you can easily [by editing four lines of tommath.h]
+          change the name of the heap functions used in LTM [also compatible with LTC via MPI mode]
+       -- Added bn_prime_rabin_miller_trials() which gives the number of Rabin-Miller trials to achieve
+          a failure rate of less than 2^-96
+       -- fixed bug in fast_mp_invmod().  The initial testing logic was wrong.  An invalid input is not when
+          "a" and "b" are even it's when "b" is even [the algo is for odd moduli only].
+       -- Started a new manual [finally].  It is incomplete and will be finished as time goes on.  I had to stop
+          adding full demos around half way in chapter three so I could at least get a good portion of the
+          manual done.   If you really need help using the library you can always email me!
+       -- My Textbook is now included as part of the package [all Public Domain]
+
+Sept 19th, 2003
+v0.27  -- Removed changes.txt~ which was made by accident since "kate" decided it was
+          a good time to re-enable backups... [kde is fun!]
+       -- In mp_grow() "a->dp" is not overwritten by realloc call [re: memory leak]
+          Now if mp_grow() fails the mp_int is still valid and can be cleared via
+          mp_clear() to reclaim the memory.
+       -- Henrik Goldman found a buffer overflow bug in mp_add_d().  Fixed.
+       -- Cleaned up mp_mul_d() to be much easier to read and follow.
+
+Aug 29th, 2003
+v0.26  -- Fixed typo that caused warning with GCC 3.2
+       -- Martin Marcel noticed a bug in mp_neg() that allowed negative zeroes.
+          Also, Martin is the fellow who noted the bugs in mp_gcd() of 0.24/0.25.
+       -- Martin Marcel noticed an optimization [and slight bug] in mp_lcm().
+       -- Added fix to mp_read_unsigned_bin to prevent a buffer overflow.
+       -- Beefed up the comments in the baseline multipliers [and montgomery]
+       -- Added "mont" demo to the makefile.msvc in etc/
+       -- Optimized sign compares in mp_cmp from 4 to 2 cases.
+
+Aug 4th, 2003
+v0.25  -- Fix to mp_gcd again... oops (0,-a) == (-a, 0) == a
+       -- Fix to mp_clear which didn't reset the sign  [Greg Rose]
+       -- Added mp_error_to_string() to convert return codes to strings.  [Greg Rose]
+       -- Optimized fast_mp_invmod() to do the test for invalid inputs [both even]
+          first so temps don't have to be initialized if it's going to fail.
+       -- Optimized mp_gcd() by removing mp_div_2d calls for when one of the inputs
+          is odd.
+       -- Tons of new comments, some indentation fixups, etc.
+       -- mp_jacobi() returns MP_VAL if the modulus is less than or equal to zero.
+       -- fixed two typos in the header of each file :-)
+       -- LibTomMath is officially Public Domain [see LICENSE]
+
+July 15th, 2003
+v0.24  -- Optimized mp_add_d and mp_sub_d to not allocate temporary variables
+       -- Fixed mp_gcd() so the gcd of 0,0 is 0.  Allows the gcd operation to be chained
+          e.g. (0,0,a) == a [instead of 1]
+       -- Should be one of the last release for a while.  Working on LibTomMath book now.
+       -- optimized the pprime demo [/etc/pprime.c] to first make a huge table of single
+          digit primes then it reads them randomly instead of randomly choosing/testing single
+          digit primes.
+
+July 12th, 2003
+v0.23  -- Optimized mp_prime_next_prime() to not use mp_mod [via is_divisible()] in each
+          iteration.  Instead now a smaller table is kept of the residues which can be updated
+          without division.
+       -- Fixed a bug in next_prime() where an input of zero would be treated as odd and
+          have two added to it [to move to the next odd].
+       -- fixed a bug in prime_fermat() and prime_miller_rabin() which allowed the base
+          to be negative, zero or one.  Normally the test is only valid if the base is
+          greater than one.
+       -- changed the next_prime() prototype to accept a new parameter "bbs_style" which
+          will find the next prime congruent to 3 mod 4.  The default [bbs_style==0] will
+          make primes which are either congruent to 1 or 3 mod 4.
+       -- fixed mp_read_unsigned_bin() so that it doesn't include both code for
+          the case DIGIT_BIT < 8 and >= 8
+       -- optimized div_d() to easy out on division by 1 [or if a == 0] and use
+          logical shifts if the divisor is a power of two.
+       -- the default DIGIT_BIT type was not int for non-default builds.  Fixed.
+
+July 2nd, 2003
+v0.22  -- Fixed up mp_invmod so the result is properly in range now [was always congruent to the inverse...]
+       -- Fixed up s_mp_exptmod and mp_exptmod_fast so the lower half of the pre-computed table isn't allocated
+          which makes the algorithm use half as much ram.
+       -- Fixed the install script not to make the book :-) [which isn't included anyways]
+       -- added mp_cnt_lsb() which counts how many of the lsbs are zero
+       -- optimized mp_gcd() to use the new mp_cnt_lsb() to replace multiple divisions by two by a single division.
+       -- applied similar optimization to mp_prime_miller_rabin().
+       -- Fixed a bug in both mp_invmod() and fast_mp_invmod() which tested for odd
+          via "mp_iseven() == 0" which is not valid [since zero is not even either].
+
+June 19th, 2003
+v0.21  -- Fixed bug in mp_mul_d which would not handle sign correctly [would not always forward it]
+       -- Removed the #line lines from gen.pl [was in violation of ISO C]
+
+June 8th, 2003
+v0.20  -- Removed the book from the package.  Added the TDCAL license document.
+       -- This release is officially pure-bred TDCAL again [last officially TDCAL based release was v0.16]
+
+June 6th, 2003
+v0.19  -- Fixed a bug in mp_montgomery_reduce() which was introduced when I tweaked mp_rshd() in the previous release.
+          Essentially the digits were not trimmed before the compare which cause a subtraction to occur all the time.
+       -- Fixed up etc/tune.c a bit to stop testing new cutoffs after 16 failures [to find more optimal points].
+          Brute force ho!
+
+
+May 29th, 2003
+v0.18  -- Fixed a bug in s_mp_sqr which would handle carries properly just not very elegantly.
+          (e.g. correct result, just bad looking code)
+       -- Fixed bug in mp_sqr which still had a 512 constant instead of MP_WARRAY
+       -- Added Toom-Cook multipliers [needs tuning!]
+       -- Added efficient divide by 3 algorithm mp_div_3
+       -- Re-wrote mp_div_d to be faster than calling mp_div
+       -- Added in a donated BCC makefile and a single page LTM poster (ahalhabsi@sbcglobal.net)
+       -- Added mp_reduce_2k which reduces an input modulo n = 2**p - k for any single digit k
+       -- Made the exptmod system be aware of the 2k reduction algorithms.
+       -- Rewrote mp_dr_reduce to be smaller, simpler and easier to understand.
+
+May 17th, 2003
+v0.17  -- Benjamin Goldberg submitted optimized mp_add and mp_sub routines.  A new gen.pl as well
+          as several smaller suggestions.  Thanks!
+       -- removed call to mp_cmp in inner loop of mp_div and put mp_cmp_mag in its place :-)
+       -- Fixed bug in mp_exptmod that would cause it to fail for odd moduli when DIGIT_BIT != 28
+       -- mp_exptmod now also returns errors if the modulus is negative and will handle negative exponents
+       -- mp_prime_is_prime will now return true if the input is one of the primes in the prime table
+       -- Damian M Gryski (dgryski@uwaterloo.ca) found a index out of bounds error in the
+          mp_fast_s_mp_mul_high_digs function which didn't come up before.  (fixed)
+       -- Refactored the DR reduction code so there is only one function per file.
+       -- Fixed bug in the mp_mul() which would erroneously avoid the faster multiplier [comba] when it was
+          allowed.  The bug would not cause the incorrect value to be produced just less efficient (fixed)
+       -- Fixed similar bug in the Montgomery reduction code.
+       -- Added tons of (mp_digit) casts so the 7/15/28/31 bit digit code will work flawlessly out of the box.
+          Also added limited support for 64-bit machines with a 60-bit digit.  Both thanks to Tom Wu (tom@arcot.com)
+       -- Added new comments here and there, cleaned up some code [style stuff]
+       -- Fixed a lingering typo in mp_exptmod* that would set bitcnt to zero then one.  Very silly stuff :-)
+       -- Fixed up mp_exptmod_fast so it would set "redux" to the comba Montgomery reduction if allowed.  This
+          saves quite a few calls and if statements.
+       -- Added etc/mont.c a test of the Montgomery reduction [assuming all else works :-| ]
+       -- Fixed up etc/tune.c to use a wider test range [more appropriate] also added a x86 based addition which
+          uses RDTSC for high precision timing.
+       -- Updated demo/demo.c to remove MPI stuff [won't work anyways], made the tests run for 2 seconds each so its
+          not so insanely slow.  Also made the output space delimited [and fixed up various errors]
+       -- Added logs directory, logs/graph.dem which will use gnuplot to make a series of PNG files
+          that go with the pre-made index.html.  You have to build [via make timing] and run ltmtest first in the
+          root of the package.
+       -- Fixed a bug in mp_sub and mp_add where "-a - -a" or "-a + a" would produce -0 as the result [obviously invalid].
+       -- Fixed a bug in mp_rshd.  If the count == a.used it should zero/return [instead of shifting]
+       -- Fixed a "off-by-one" bug in mp_mul2d.  The initial size check on alloc would be off by one if the residue
+          shifting caused a carry.
+       -- Fixed a bug where s_mp_mul_digs() would not call the Comba based routine if allowed.  This made Barrett reduction
+          slower than it had to be.
+
+Mar 29th, 2003
+v0.16  -- Sped up mp_div by making normalization one shift call
+       -- Sped up mp_mul_2d/mp_div_2d by aliasing pointers :-)
+       -- Cleaned up mp_gcd to use the macros for odd/even detection
+       -- Added comments here and there, mostly there but occasionally here too.
+
+Mar 22nd, 2003
+v0.15  -- Added series of prime testing routines to lib
+       -- Fixed up etc/tune.c
+       -- Added DR reduction algorithm
+       -- Beefed up the manual more.
+       -- Fixed up demo/demo.c so it doesn't have so many warnings and it does the full series of
+          tests
+       -- Added "pre-gen" directory which will hold a "gen.pl"'ed copy of the entire lib [done at
+          zipup time so its always the latest]
+       -- Added conditional casts for C++ users [boo!]
+
+Mar 15th, 2003
+v0.14  -- Tons of manual updates
+       -- cleaned up the directory
+       -- added MSVC makefiles
+       -- source changes [that I don't recall]
+       -- Fixed up the lshd/rshd code to use pointer aliasing
+       -- Fixed up the mul_2d and div_2d to not call rshd/lshd unless needed
+       -- Fixed up etc/tune.c a tad
+       -- fixed up demo/demo.c to output comma-delimited results of timing
+          also fixed up timing demo to use a finer granularity for various functions
+       -- fixed up demo/demo.c testing to pause during testing so my Duron won't catch on fire
+          [stays around 31-35C during testing :-)]
+
+Feb 13th, 2003
+v0.13  -- tons of minor speed-ups in low level add, sub, mul_2 and div_2 which propagate
+          to other functions like mp_invmod, mp_div, etc...
+       -- Sped up mp_exptmod_fast by using new code to find R mod m [e.g. B^n mod m]
+       -- minor fixes
+
+Jan 17th, 2003
+v0.12  -- re-wrote the majority of the makefile so its more portable and will
+          install via "make install" on most *nix platforms
+       -- Re-packaged all the source as seperate files.  Means the library a single
+          file packagage any more.  Instead of just adding "bn.c" you have to add
+          libtommath.a
+       -- Renamed "bn.h" to "tommath.h"
+       -- Changes to the manual to reflect all of this
+       -- Used GNU Indent to clean up the source
+
+Jan 15th, 2003
+v0.11  -- More subtle fixes
+       -- Moved to gentoo linux [hurrah!] so made *nix specific fixes to the make process
+       -- Sped up the montgomery reduction code quite a bit
+       -- fixed up demo so when building timing for the x86 it assumes ELF format now
+
+Jan 9th, 2003
+v0.10  -- Pekka Riikonen suggested fixes to the radix conversion code.
+       -- Added baseline montgomery and comba montgomery reductions, sped up exptmods
+          [to a point, see bn.h for MONTGOMERY_EXPT_CUTOFF]
+
+Jan 6th, 2003
+v0.09  -- Updated the manual to reflect recent changes.  :-)
+       -- Added Jacobi function (mp_jacobi) to supplement the number theory side of the lib
+       -- Added a Mersenne prime finder demo in ./etc/mersenne.c
+
+Jan 2nd, 2003
+v0.08  -- Sped up the multipliers by moving the inner loop variables into a smaller scope
+       -- Corrected a bunch of small "warnings"
+       -- Added more comments
+       -- Made "mtest" be able to use /dev/random, /dev/urandom or stdin for RNG data
+       -- Corrected some bugs where error messages were potentially ignored
+       -- add etc/pprime.c program which makes numbers which are provably prime.
+
+Jan 1st, 2003
+v0.07  -- Removed alot of heap operations from core functions to speed them up
+       -- Added a root finding function [and mp_sqrt macro like from MPI]
+       -- Added more to manual
+
+Dec 31st, 2002
+v0.06  -- Sped up the s_mp_add, s_mp_sub which inturn sped up mp_invmod, mp_exptmod, etc...
+       -- Cleaned up the header a bit more
+
+Dec 30th, 2002
+v0.05  -- Builds with MSVC out of the box
+       -- Fixed a bug in mp_invmod w.r.t. even moduli
+       -- Made mp_toradix and mp_read_radix use char instead of unsigned char arrays
+       -- Fixed up exptmod to use fewer multiplications
+       -- Fixed up mp_init_size to use only one heap operation
+          -- Note there is a slight "off-by-one" bug in the library somewhere
+             without the padding (see the source for comment) the library
+             crashes in libtomcrypt.  Anyways a reasonable workaround is to pad the
+             numbers which will always correct it since as the numbers grow the padding
+             will still be beyond the end of the number
+       -- Added more to the manual
+
+Dec 29th, 2002
+v0.04  -- Fixed a memory leak in mp_to_unsigned_bin
+       -- optimized invmod code
+       -- Fixed bug in mp_div
+       -- use exchange instead of copy for results
+       -- added a bit more to the manual
+
+Dec 27th, 2002
+v0.03  -- Sped up s_mp_mul_high_digs by not computing the carries of the lower digits
+       -- Fixed a bug where mp_set_int wouldn't zero the value first and set the used member.
+       -- fixed a bug in s_mp_mul_high_digs where the limit placed on the result digits was not calculated properly
+       -- fixed bugs in add/sub/mul/sqr_mod functions where if the modulus and dest were the same it wouldn't work
+       -- fixed a bug in mp_mod and mp_mod_d concerning negative inputs
+       -- mp_mul_d didn't preserve sign
+       -- Many many many many fixes
+       -- Works in LibTomCrypt now :-)
+       -- Added iterations to the timing demos... more accurate.
+       -- Tom needs a job.
+
+Dec 26th, 2002
+v0.02  -- Fixed a few "slips" in the manual.  This is "LibTomMath" afterall :-)
+       -- Added mp_cmp_mag, mp_neg, mp_abs and mp_radix_size that were missing.
+       -- Sped up the fast [comba] multipliers more [yahoo!]
+
+Dec 25th,2002
+v0.01  -- Initial release.  Gimme a break.
+       -- Todo list,
+           add details to manual [e.g. algorithms]
+           more comments in code
+           example programs

+To use the pretty graphs you have to first build/run the ltmtest from the root directory of the package.  
+Todo this type 
+
+make timing ; ltmtest
+
+in the root.  It will run for a while [about ten minutes on most PCs] and produce a series of .log files in logs/.
+
+After doing that run "gnuplot graphs.dem" to make the PNGs.  If you managed todo that all so far just open index.html to view
+them all :-)
+
+Have fun
