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)
