|
|
|
2 v0.96 -- Removed GF and Keyring code
|
|
|
3 -- Extended OAEP decoder to distinguish better [and use a more uniform API]
|
|
|
4 -- Changed PSS/OAEP API slightly to be more consistent with other PK functions (order of arguments)
|
|
|
5 -- rsa_exptmod() now pads with leading zeroes as per I2OSP.
|
|
|
6 -- added error checking to yarrow code
|
|
|
7 -- Mike Frysinger pointed out that tommath.h from this distro will overwrite tommath.h
|
|
|
8 from libtommath. I changed this to ltc_tommath.h to avoid any such problems.
|
|
|
9 -- Fixed bug in PSS encoder/decoder that didn't handle the MSB properly
|
|
|
10 -- refactored AES, now sports an "encrypt only" descriptor which uses half as much code space.
|
|
|
11 -- modded Yarrow to try and use refactored AES code and added WHIRLPOOL support (d'oh) ;-)
|
|
|
12 -- updated ECB, OCB and CBC decrypt functions to detect when "encrypt only" descriptor is used.
|
|
|
13 -- replaced old RSA code with new code that uses PKCS #1 v2.0 padding
|
|
|
14 -- replaced old test harness with new over-engineer'ed one in /demos/test/
|
|
|
15 -- updated cbc/cfb/ofb/ctr code with setiv/getiv functions to change/read the IV without re-keying.
|
|
|
16 -- Added PKCS #1 v1.5 RSA encryption and signature padding routines
|
|
|
17 -- Added DER OID's to most hash descriptors (as many as I could find)
|
|
|
18 -- modded rsa_exptmod() to use timing-resilient tim_exptmod() when doing private key operations
|
|
|
19 added #define RSA_TIMING which can turn on/off this feature.
|
|
|
20 -- No more config.pl so please just read mycrypt_custom.h for build-time tweaks
|
|
|
21 -- Small update to rand_prime()
|
|
|
22 -- Updated sha1, md5 and sha256 so they are smaller when SMALL_CODE is defined. If you want speed though,
|
|
|
23 you're going to have to undefine SMALL_CODE ;-)
|
|
|
24 -- Worked over AES so that it's even smaller now [in both modes].
|
|
|
25
|
|

|
26 May 12th, 2004
|
|
|
27 v0.95 -- Optimized AES and WHIRLPOOL for SMALL_CODE by taking advantage of the fact
|
|
|
28 the transforms are circulant. AES dropped 5KB and WHIRLPOOL dropped 13KB
|
|
|
29 using the default build options on the x86.
|
|
|
30 -- Updated eax so the eax_done() would clear the state [like hmac,pmac,ocb] when
|
|
|
31 CLEAN_STACK has been defined.
|
|
|
32 -- added LTC_TEST support to rmd160
|
|
|
33 -- updates to mycrypt_pk.h
|
|
|
34 -- updated rand_prime() to faciliate making RSA composites
|
|
|
35 -- DSA/RSA now makes composites of the exact size desired.
|
|
|
36 -- Refactored quite a bit of the code, fewer functions per C file
|
|
|
37 -- cleaned up the makefiles to organize the objects logically
|
|
|
38 -- added ICC makefile along with "profiled" targets for both GNU and ICC compilers
|
|
|
39 -- Marked functions for removal before v1.00 see PLAN for more information
|
|
|
40 -- GCC 3.4.0 tested and seems to work
|
|
|
41 -- Added PKCS #5 support
|
|
|
42 -- Fixed typo in comment header of .C files ;-)
|
|
|
43 -- Added PKCS #1 OAEP and PSS support.
|
|
|
44
|
|
|
45 Feb 20th, 2004
|
|
|
46 v0.94 -- removed unused variables from ocb.c and fixed it to match known test vectors.
|
|
|
47 -- Added PMAC support, minor changes to OMAC/EAX code [I think....]
|
|
|
48 -- Teamed up with Brian Gladman. His code verifies against my vectors and my code
|
|
|
49 verifies against his test vectors. Hazaa for co-operation!
|
|
|
50 -- Various small changes (added missing ARGCHKs and cleaned up indentation)
|
|
|
51 -- Optimization to base64, removed unused variable "c"
|
|
|
52 -- Added base64 gen to demos/tv_gen.c
|
|
|
53 -- Fix to demos/x86_prof.c to correctly identify the i386 architecture... weird...
|
|
|
54 -- Fixed up all of the PK code by adding missing error checking, removed "res" variables,
|
|
|
55 shrunk some stack variables, removed non-required stack variables and added proper
|
|
|
56 error conversion from MPI to LTC codes. I also spotted a few "off by one" error
|
|
|
57 checking which could have been used to force the code to read past the end of
|
|
|
58 the buffer (in theory, haven't checked if it would work) by a few bytes.
|
|
|
59 -- Added checks to OUTPUT_BIGNUM so the *_export() functions cannot overflow the output and I
|
|
|
60 also modded it so it stores in the output provided to the function (that is not on
|
|
|
61 the local stack) which saves memory and time.
|
|
|
62 -- Made SAFER default to disabled for now (plans are to cleanhouse write an implementation later)
|
|
|
63 -- Added the 512-bit one-way hash WHIRLPOOL which clocks in at 138 cycles per byte on my
|
|
|
64 Athlon XP [for comparison, SHA-512 clocks in at 77 cycles per byte]. This code uses the
|
|
|
65 teams new sbox design (not the original NESSIE one).
|
|
|
66
|
|
|
67
|
|
|
68 Jan 25th, 2004
|
|
|
69 v0.93 -- [note: deleted v0.93 changes by accident... recreating from memory...]
|
|
|
70 -- Fix to RC2 to not deference pointer before ARGCHK
|
|
|
71 -- Fix to NOEKEON to match published test vectors as well as cleaned up the code a bit
|
|
|
72 -- Optimized Twofish [down to 28 cycles/byte on my box] and Blowfish
|
|
|
73 -- Fix to OMAC to test cipher block size first [prevents wasting any time]
|
|
|
74 -- Added more OMAC test vectors
|
|
|
75 -- Added EAX Encrypt+Authenticate support
|
|
|
76 -- Fix to DSA to check return of a few LTM functions I forgot [mp_to_unsigned_bin]
|
|
|
77 -- Added common headers to all C files
|
|
|
78 -- CTR mode supports big and little [default] endian counters now.
|
|
|
79 -- fix to find_cipher_any() so that it can handle a fragmented cipher_descriptor table.
|
|
|
80 -- added find_hash_any() akin to find_cipher_any().
|
|
|
81 -- Added EAX code to demos/tv_gen.c Hazaa!
|
|
|
82 -- Removed SONY defines and files from codebase.
|
|
|
83 -- Added OCB support [patents be damned] and to demos/tv_gen.c
|
|
|
84 -- Merge all of the INPUT/OUTPUT BIGNUM macros (less toc) into mycrypt_pk.h
|
|
|
85 -- Made appropriate changes to the debug string in crypt.c
|
|
|
86
|
|
|
87 Dec 24th, 2003
|
|
|
88 v0.92 -- Updated the config.pl script so the options have more details.
|
|
|
89 -- Updated demos/tv_gen to include RIPEMD hashes
|
|
|
90 -- Updated Twofish so when TWOFISH_ALL_TABLES is defined a pre-computed RS table
|
|
|
91 is included [speedup: slight, about 4k cycles on my Athlon].
|
|
|
92 -- Re-wrote the twofish large key generation [the four 8x32 key dependent tables]. Now about twice as fast.
|
|
|
93 With both optimizations [e.g. TWOFISH_ALL_TABLES defined] a 128-bit Twofish key can now be scheduled
|
|
|
94 in 26,000 cycles on my Athlon XP [as opposed to 49,000 before] when optimized for size.
|
|
|
95 -- config.pl has been updated so rmd128.o and rmd160.o are objects included in the build [oops]
|
|
|
96 -- Andrew Mann found a bug in rsa_exptmod() which wouldn't indicate if the wrong type of key was specified
|
|
|
97 (e.g. not PK_PRIVATE or PK_PUBLIC)
|
|
|
98 -- Fixed up demos/x86_prof so it sorts the output now :-)
|
|
|
99 -- The project is now powered by radioactive rubber pants.
|
|
|
100 -- Fixed dh_encrypt_key() so if you pass it a hash with a smaller output than the input key it
|
|
|
101 will return CRYPT_INVALID_HASH [to match what ecc_encrypt_key() will do]
|
|
|
102 -- Merge the store/encrypt key part of ecc_encrypt_key() as per dh_encrypt_key() [can you guess what I'm upto?]
|
|
|
103 -- Massive updates to the prime generation code. I use the LTM random prime functions [and provide a nice
|
|
|
104 interface between the LTC PRNG's and the LTM generic prng prototype]. I also use a variable number of tests
|
|
|
105 depending on the input size. This nicely speeds up most prime generation/testing within the library.
|
|
|
106 -- Added SHA-224 to the list of hashes.
|
|
|
107 -- Made HMAC test vectors constant and static [takes ROM space instead of RAM]
|
|
|
108 -- This release was brought to you by the letter P which stands for Patent Infringement.
|
|
|
109 -- Added generic HASH_PROCESS macro to mycrypt_hash.h which simplifies the hash "process" functions
|
|
|
110 I also optimized the compression functions of all but MD2 to not perform input copies when avoidable.
|
|
|
111 -- Removed the division from the Blowfish setup function [dropped 3k cycles on my Athlon]
|
|
|
112 -- Added stack cleaning to rijndael, cast5 so now all ciphers have CLEAN_STACK code.
|
|
|
113 -- Added Skipjack to the list of ciphers [made appropriate changes to demos/test.c, demos/tv_gen.c and
|
|
|
114 demos/x86_prof.c]
|
|
|
115 -- Added mechanical testing to cipher test vector routines. Now it encrypts 1000 times, then decrypts and
|
|
|
116 compares. Any fault (e.g. bug in code, compiler) in the routines is likely to show through. Doesn't
|
|
|
117 stress test the key gen though...
|
|
|
118 -- Matt Johnson found a bug in the blowfish.c apparently I was out of my mind and put twofish defines in there
|
|
|
119 The code now builds with any config. Thanks.
|
|
|
120 -- Added OMAC1 Message Authentication Code support to the library.
|
|
|
121 -- Re-prototyped the hash "process" and "done" to prevent buffer overflows [which don't seem easy to exploit].
|
|
|
122 Updated HMAC code to use them too. Hazaa!
|
|
|
123 -- Fixed bug in ECC code which wouldn't do an _ARGCHK on stat in ecc_verify_hash().
|
|
|
124 -- Fixed [temp fix] bug in all PK where the OUTPUT_BIGNUM macros would not trap errors on the to_unsigned_bin
|
|
|
125 conversion [now returns CRYPT_MEM, will fix it up better later]
|
|
|
126 -- Added DSA to the list of supported PK algorithms.
|
|
|
127 -- Fixed up various ciphers to &255 the input key bytes where required [e.g. where used to index a table] to prevent
|
|
|
128 problems on platforms where CHAR_BIT != 8
|
|
|
129 -- Merged in LibTomMath v0.28
|
|
|
130 -- Updated demos/x86_prof.c to use Yarrow during the key sched testing [was horribly slow on platforms with blockable
|
|
|
131 /dev/random].
|
|
|
132 -- Added OMAC/HMAC tests to demos/tv_gen and I now store the output of this in notes/
|
|
|
133 -- Fixed a bug in config.pl that wouldn't have TWOFISH_TABLES defined by default (too many commas on the line)
|
|
|
134 -- Fixed bug in hmac_done(). Apparently FIPS-198 [HMAC] specifies that the output can be truncated. My code
|
|
|
135 would not support that (does now just like the new OMAC code).
|
|
|
136 -- Removed "hashsize" from hmac_state as it wasn't being used.
|
|
|
137 -- Made demos/test.c stop if OMAC or HMAC tests fail (instead of just printing a failed message and keep going).
|
|
|
138 -- Updated notes/tech0003.txt to take into account the existence of Skipjack [also I fixed a few typos].
|
|
|
139 -- Slight changes to Noekeon, with SMALL_CODE undefined it uses a fully unrolled version. Dropped +10 cycles/byte
|
|
|
140 on my Athlon (35 cycles per byte or 410.4Mbit/sec at 1795Mhz)
|
|
|
141 -- Added _ARGCHK() calls to is_prime() for the two input pointers.
|
|
|
142
|
|
|
143 Sept 25th, 2003
|
|
|
144 v0.91 -- HMAC fix of 0.90 was incorrect for keys larger than the block size of the hash.
|
|
|
145 -- Added error CRYPT_FILE_NOTFOUND for the file [hmac/hash] routines.
|
|
|
146 -- Added RIPEMD hashes to the hashsum demo.
|
|
|
147 -- Added hashsum demo to MSVC makefile.
|
|
|
148 -- Added RMD160 to the x86_prof demo [oops]
|
|
|
149 -- Merged in LibTomMath-0.27 with a patch to mp_shrink() that will be in LibTomMath-0.28
|
|
|
150 Fixes another potential memory leak.
|
|
|
151
|
|
|
152 Sept 7th, 2003
|
|
|
153 v0.90 -- new ROL/ROR for x86 GCC
|
|
|
154 -- Jochen Katz submitted a patch to the makefile to prevent "make" from making the .a library
|
|
|
155 when not required.
|
|
|
156 == By default the KR code is not enabled [it's only a demo anyways!]
|
|
|
157 -- changed the "buf" in ecc_make_key from 4KB to 128 bytes [since the largest key is 65 bytes]
|
|
|
158 -- hmac_done() now requires you pass it the size of the destination buffer to prevent
|
|
|
159 buffer overflows. (API CHANGE)
|
|
|
160 -- hmac/hash filebased routines now return CRYPT_NOP if NO_FILE is defined.
|
|
|
161 -- I've removed the primes from dh.c and replaced them with DR safe primes suitable for the default
|
|
|
162 configuration of LibTomMath. Check out these comparisons on a 1.3Ghz Athlon XP, optimized for size,
|
|
|
163
|
|
|
164 768-bit, 4 vs. 10
|
|
|
165 1024-bit, 8 vs. 18
|
|
|
166 1280-bit, 12 vs. 34
|
|
|
167 1536-bit, 20 vs. 56
|
|
|
168 1792-bit 28 vs. 88
|
|
|
169 2048-bit, 40 vs. 124
|
|
|
170 2560-bit, 71 vs. 234
|
|
|
171 3072-bit, 113 vs. 386
|
|
|
172 4096-bit, 283 vs. 916
|
|
|
173
|
|
|
174 Times are all in milliseconds for key generation. New primes times on the left. This makes the code binary
|
|
|
175 incompatible with previous releases. However, this addition is long overdue as LibTomMath has supported DR
|
|
|
176 reductions for quite some time.
|
|
|
177 -- Added RIPE-MD 128 and 160 to the list of supported hashes [10 in total].
|
|
|
178 -- The project has been released as public domain. TDCAL no longer applies.
|
|
|
179
|
|
|
180 July 15th, 2003
|
|
|
181 v0.89 -- Fix a bug in bits.c which would prevent it from building with msvc
|
|
|
182 -- Merged in LibTomMath v0.24 [and I used the alloc/free macros this time!]
|
|
|
183 -- Removed the LTC version of next_prime() and replaced it with a call to the
|
|
|
184 mp_prime_next_prime() from LibTomMath
|
|
|
185 -- reverted bits.c to the 0.86 copy since the new one doesn't build in MSVC
|
|
|
186 or cygwin.
|
|
|
187
|
|
|
188 Jul 10th, 2003
|
|
|
189 v0.88 -- Sped up CAST5 key schedule for MSVC
|
|
|
190 -- added "ulong32" which allows people on 64-bit platforms to force the 32-bit tables in
|
|
|
191 ciphers like blowfish and AES to be 32-bits. E.g. when unsigned long is 64-bits.
|
|
|
192 -- Optimized the SAFER-SK64, SAFER-SK128, SAFER+, RC5 and RC6 key schedule [big time!]
|
|
|
193 -- Optimized SHA-1 and SHA-256 quite a bit too.
|
|
|
194 -- Fixed up the makefile to use -fomit-frame-pointer more liberally
|
|
|
195 -- Added tv_gen program which makes test vectors for ciphers/hashes
|
|
|
196 -- Merged in LibTomMath v0.22
|
|
|
197
|
|
|
198 Jun 19th, 2003
|
|
|
199 v0.87 -- Many MSVC optimizations to the code base
|
|
|
200 -- Improved the AES and Twofish key schedule [faster, more constant time]
|
|
|
201 -- Tons of optimizations here and there.
|
|
|
202
|
|
|
203 Jun 15th, 2003
|
|
|
204 v0.86 -- Fixed up AES to workaround MSVC optimizer bug
|
|
|
205 -- Merged in fresh LTM base [based on v0.20] so there are no warnings with MSVC
|
|
|
206 -- Wrote x86_prof which will time the hashes and ciphers downto cycles per byte.
|
|
|
207 -- Fixed up demos/encrypt to remove serpent_desc from the list
|
|
|
208 -- Re-enabled MSVC optimizations w00t w00t
|
|
|
209 -- Replaced "errno" with "err" in all functions that had it so it wouldn't clash
|
|
|
210 with the global "errno"

219 Jun 1st, 2003
|
|
|
220 v0.84 -- Removed a 4KB buffer from rsa_decrypt_key that wasn't being used no more
|
|
|
221 -- Fixed another potential buffer problem. Not an overflow but could cause the
|
|
|
222 PK import routines to read past the end of the buffer.
|
|
|
223 -- Optimized the ECC mulmod more by removing a if condition that will always be false
|
|
|
224 -- Optimized prime.c to not include a 2nd prime table, removed code from is_prime calls prime
|
|
|
225 test from LibTomMath now
|
|
|
226 -- Added LTC_TEST define which when defined will enable the test vector routines [see mycrypt_custom.h]
|
|
|
227 -- Removed ampi.o from the depends cuz it ain't no not working in *nix with it [routines are in mpi.c now].
|
|
|
228
|
|
|
229
|
|
|
230 Mar 29th, 2003
|
|
|
231 v0.83 -- Optimized the ecc_mulmod, it's faster and takes less heap/stack space
|
|
|
232 -- Fixed a free memory error in ecc_mulmod and del_point which would try to free NULL
|
|
|
233 -- Fixed two serious bugs in rsa_decrypt_key and rsa_verify_hash that would allow a trivialy
|
|
|
234 buffer overflow.
|
|
|
235 -- Fixed a bug in the hmac testing code if you don't register all the hashes it won't return
|
|
|
236 errors now.
|
|
|
237
|
|
|
238 Mar 15th, 2003
|
|
|
239 v0.82 -- Manual updated
|
|
|
240 -- Added MSVC makefile [back, actually its written from scratch to work with NMAKE]
|
|
|
241 -- Change to HMAC helper functions API to avoid buffer overflow [source changes]
|
|
|
242 -- the rsa_encrypt_key was supposed to reject key sizes out of bounds ...
|
|
|
243 same fix to the rsa_sign_hash
|
|
|
244 -- Added code to ensure that that chaining mode code (cfb/ofb/ctr/cbc) have valid
|
|
|
245 structures when being called. E.g. the indexes to the pad/ivs are not out of bounds
|
|
|
246 -- Cleaned up the DES code and simplified the core desfunc routine.
|
|
|
247 -- Simplified one of the boolean functions in MD4
|
|
|
248
|
|
|
249 Jan 16th, 2003
|
|
|
250 v0.81 -- Merged in new makefile from Clay Culver and Mike Frysinger
|
|
|
251 -- Sped up the ECC mulmod() routine by making the word size adapt to the input. Saves a whopping 9 point
|
|
|
252 operations on 521-bit keys now (translates to about 8ms on my Athlon XP). I also now use barrett reduction
|
|
|
253 as much as possible. This sped the routine up quite a bit.
|
|
|
254 -- Fixed a huge flaw in ecc_verify_hash() where it would return CRYPT_OK on error... Now fixed.
|
|
|
255 -- Fixed up config.pl by fixing an invalid query and the file is saved in non-windows [e.g. not CR/LF] format
|
|
|
256 (fix due to Mika Bostr�m)
|
|
|
257 -- Merged in LibTomMath for kicks
|
|
|
258 -- Changed the build process so that by default "mycrypt_custom.h" is included and provided
|
|
|
259 The makefile doesn't include any build options anymore
|
|
|
260 -- Removed the PS2 and VC makefiles.
|
|
|
261
|
|
|
262 Dec 16th, 2002
|
|
|
263 v0.80 -- Found a change I made to the MPI that is questionable. Not quite a bug but definately not desired. Had todo
|
|
|
264 with the digit shifting. In v0.79 I simply truncated without zeroing. It didn't cause problems during my
|
|
|
265 testing but I fixed it up none the less.
|
|
|
266 -- Optimized s_mp_mul_dig() from MPI to do a minimal number of passes.
|
|
|
267 -- Fixed in rsa_exptmod() where I was getting the size of the result. Basically it accomplishes the same thing
|
|
|
268 but the fixed code is more readable.
|
|
|
269 -- Fixed slight bug in dh_sign_hash() where the random "k" value was 1 byte shorter than it should have been. I've
|
|
|
270 also made the #define FAST_PK speed up signatures as well. Essentially FAST_PK tells the DH sub-system to
|
|
|
271 limit any private exponent to 256-bits. Note that when FAST_PK is defined does not make the library
|
|
|
272 binary or source incompatible with a copy of the library with it undefined.
|
|
|
273 -- Removed the DSA code. If you want fast diffie-hellman just define FAST_PK :-)
|
|
|
274 -- Updated dh_sign_hash()/dh_verify_hash() to export "unsigned" bignums. Saves two bytes but is not binary
|
|
|
275 compatible with the previous release... sorry! I've performed the same fix to the ecc code as well.
|
|
|
276 -- 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]
|
|
|
277 -- Fixed a bug in the DH code where it missed trapping a few errors if they occurred.
|
|
|
278 -- Fixed a slight "its-not-a-bug-but-could-be-done-better" bug in the next_prime() function. Essentially it was
|
|
|
279 testing to ensure that in the loop that searches for the next candidate that the step never grows beyond
|
|
|
280 65000. Should have been testing for MP_DIGIT_MAX
|
|
|
281 -- Spruced up the config.pl script. It now makes a header file "mycrypt_custom.h" which can be included *before*
|
|
|
282 you include mycrypt.h. This allows you to add libtomcrypt to a project without completely changing your make
|
|
|
283 system around. Note that you should use the makefile it writes to at least build the library initially.
|
|
|
284 -- Used splint to check alot of the code out. Tons of minor fixes and explicit casts added.
|
|
|
285 -- Also made all the internal functions of MPI are now static to avoid poluting the namespace
|
|
|
286 -- **Notice**: There are no planned future releases for at least a month from the this release date.
|
|
|
287
|
|
|
288 Dec 14th, 2002
|
|
|
289 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
|
|
|
290 *_verify_hash functions. This prevents malformed packets from performing buffer overflows. I've also trimmed
|
|
|
291 the packet header size [by 4 bytes].
|
|
|
292 -- Made the test program halt on the first error it occurs. Also made it trap more errors than before.
|
|
|
293 -- Wrote the first chapter of my new book [DRAFT!], not in this package but check my website!
|
|
|
294 -- Included a perl script "config.pl" that will make "makefile.out" according to the users needs.
|
|
|
295 -- Added shell script to look for latest release
|
|
|
296 -- Merge DH and ECC key defines from mycrypt_cfg.h into the makefiles
|
|
|
297 -- updated the makefile to use BSD friendly archiving invokations
|
|
|
298 -- Changed the DH and ECC code to use base64 static key settings [e.g. the primes]. Dropped the code size by 3KB
|
|
|
299 and is ever-so-slightly faster than before.
|
|
|
300 -- added "mp_shrink" function to shrink the size of bignums. Specially useful for PK code :-)
|
|
|
301 -- Added new exptmod function that calculates a^b mod c with fewer multiplies then before [~20% for crypto
|
|
|
302 sized numbers]. Also added a "low mem" variant that doesn't use more than 20KB [upto 4096 bit nums] of
|
|
|
303 heap todo the calculation. Both are #define'able controlled
|
|
|
304 -- Added XREALLOC macro to provide realloc() functionality.
|
|
|
305 -- Added fix where in rsa_import() if you imported a public key or a non-optimized key it would free the mp_int's
|
|
|
306 not being used.
|
|
|
307 -- Fixed potential bug in the ECC code. Only would occur on platforms where char is not eight bits [which isn't
|
|
|
308 often!]
|
|
|
309 -- Fixed up the ECC point multiplication, its about 15% faster now
|
|
|
310 -- While I was at it [since the lib isn't binary backwards compatible anyways] I've fixed the PK export routines
|
|
|
311 so they export as "unsigned" types saving 1 byte per bignum outputted. Not a lot but heck why not.
|
|
|
312
|
|
|
313 Nov 28th, 2002
|
|
|
314 v0.78 -- Made the default ARGCHK macro a function call instead which reduced the code size from 264KB to 239KB.
|
|
|
315 -- Fixed a bug in the XTEA keysize function which called ARGCHK incorrectly.
|
|
|
316 -- Added Noekeon block cipher at 2,800 bytes of object code and 345Mbit/sec it is a welcome addition.
|
|
|
317 -- Made the KR code check if the other PK systems are included [provides error when building otherwise].
|
|
|
318 -- Made "aes" an alias for Rijndael via a pre-processor macro. Now you can use "aes_ecb_encrypt", etc... :-)
|
|
|
319 Thanks to Jean-Luc Cooke for the "buzzword conformance" suggestion.
|
|
|
320 -- Removed the old PK code entirely (e.g. rsa_sign, dh_encrypt). The *_sign_hash and *_encrypt_key functions
|
|
|
321 are all that is to remain.
|
|
|
322 -- **NOTE** Changed the PK *_import (including the keyring) routine to accept a "inlen" parameter. This fixes a
|
|
|
323 bug where improperly made key packets could result in reading passed the end of the buffer. This means
|
|
|
324 the code is no longer source compatible but still binary compatible.
|
|
|
325 -- Fixed a few other minor bugs in the PK import code while I was at it.
|
|
|
326
|
|
|
327 Nov 26th, 2002
|
|
|
328 v0.77 -- Updated the XTEA code to use pre-computed keys. With optimizations for speed it achieves 222Mbit/sec
|
|
|
329 compared to the 121Mbit/sec before. It is 288 bytes bigger than before.
|
|
|
330 -- Cleaned up some of the ciphers and hashes (coding style, cosmetic changes)
|
|
|
331 -- Optimized AES slightly for 256-bit keys [only one if statement now, still two for 192-bit keys]
|
|
|
332 -- Removed most test cases from Blowfish, left three of them there. Makes it smaller and faster to test.
|
|
|
333 -- Changed the primality routines around. I now use 8 rounds of Rabin-Miller, I use 256 primes in the sieve
|
|
|
334 step and the "rand_prime" function uses a modified sieve that avoids alot of un-needed bignum work.
|
|
|
335 -- Fixed a bug in the ECC/DH signatures where the keys "setting" value was not checked for validity. This means
|
|
|
336 that a invalid value could have caused segfaults, etc...
|
|
|
337 -- **NOTE** Changed the way the ECC/DH export/import functions work. They are source but not binary compatible
|
|
|
338 with v0.76. Essentially insteading of exporting the setting index like before I export the key size. Now
|
|
|
339 if you ever re-configure which key settings are supported the lib will still be able to make use of your
|
|
|
340 keys.
|
|
|
341 -- Optimized Blowfish by inlining the round function, unrolling it for four rounds then using a for loop for the
|
|
|
342 rest. It achieves a rate of 425Mbit/sec with the new code compared to 314Mbit/sec before. The new blowfish
|
|
|
343 object file is 7,813 bytes compared to 8,663 before and is 850 bytes smaller. So the code is both smaller and
|
|
|
344 faster!
|
|
|
345 -- Optimized Twofish as well by inlining the round function. Gets ~400Mbit/sec compared to 280Mbit/sec before
|
|
|
346 and the code is only 78 bytes larger than the previous copy.
|
|
|
347 -- Removed SMALL_PRIME_TAB build option. I use the smaller table always.
|
|
|
348 -- Fixed some mistakes concerning prime generation in the manual.
|
|
|
349 -- [Note: sizes/speeds are for GCC 3.2 on an x86 Athlon XP @ 1.53Ghz]
|
|
|
350
|
|
|
351 Nov 25th, 2002
|
|
|
352 v0.76 -- Updated makefiles a bit more, use "-Os" instead of "-O2" to optimize for size. Got the lib
|
|
|
353 downto 265KB using GCC 3.2 on my x86 box.
|
|
|
354 -- Updated the SAFER+, Twofish and Rijndael test vector routine to use the table driven design.
|
|
|
355 -- Updated all other test vector routines to return as soon as an error is found
|
|
|
356 -- fixed a bug in the test program where errors in the hash test routines would not be reported
|
|
|
357 correctly. I found this by temporarily changing one of the bytes of the test vectors. All the
|
|
|
358 hashes check out [the demos/test.c would still have reported an error, just the wrong one].
|
|
|
359
|
|
|
360
|
|
|
361 Nov 24th, 2002
|
|
|
362 v0.75 -- Fixed a flaw in hash_filehandle, it should ARGCHK that the filehandle is not NULL
|
|
|
363 -- Fixed a bug where in hash_file if the call to hash_filehandle failed the open file would
|
|
|
364 not be closed.
|
|
|
365 -- Added more strict rules to build process, starting to weed out "oh this works in GCC" style code
|
|
|
366 In the next release "-Wconversion" will be enabled which will deal with all implicit casts.
|
|
|
367
|
|
|
368 Nov 22nd, 2002 [later in the day]
|
|
|
369 v0.74 -- Wrote a small variant of SAFER+ which shaved 50KB off the size of the library on x86 platforms
|
|
|
370 -- Wrote a build option to remove the PK packet functions [keeps the encrypt_key/sign_hash functions]
|
|
|
371 -- Wrote a small variant of Rijndael (trimmed 13KB)
|
|
|
372 -- Trimmed the TIGER/192 hash function a bit
|
|
|
373 -- Overall the entire lib compiled is 295KB [down from 400KB before]
|
|
|
374 -- Fixed a few minor oversights in the MSVC makefile
|
|
|
375
|
|
|
376 Nov 22nd, 2002
|
|
|
377 v0.73 -- Fixed bug in RC4 code where it could only use 255 byte keys.
|
|
|
378 -- Fixed bug in yarrow code where it would allow cast5 or md2 to be used with it...
|
|
|
379 -- Removed the ecc compress/expand points from the global scope. Reduces namespace polution
|
|
|
380 -- Fixed bug where if you used the SPRNG you couldn't pass NULL as your prng_state which you should be
|
|
|
381 able todo since the SPRNG has no state...
|
|
|
382 -- Corrected some oversights in the manual and the examples...
|
|
|
383 -- By default the GF(2^W) math library is excluded from the build. The source is maintained because I wrote it
|
|
|
384 and like it :-). This way the built library is a tad smaller
|
|
|
385 -- the MSVC makefile will now build for a SPACE optimized library rather than TIME optimized.
|
|
|
386
|
|
|
387 Nov 21th, 2002
|
|
|
388 v0.72 -- Fixed bug in the prime testing. In the Miller-Rabin test I was raising the base to "N-1" not "r".
|
|
|
389 The math still worked out fine because in effect it was performing a Fermat test. Tested the new code and it
|
|
|
390 works properly
|
|
|
391 -- Fixed some of the code where it was still using the old error syntax
|
|
|
392 -- Sped up the RSA decrypt/sign routines
|
|
|
393 -- Optimized the ecc_shared_secret routine to not use so much stack
|
|
|
394 -- Fixed up the makefile to make releases where the version # is in the file name and directory it will unzip
|
|
|
395 to
|
|
|
396
|
|
|
397 Nov 19th, 2002
|
|
|
398 v0.71 -- HELP TOM. I need tuition for the January semester. Now I don't want to force donations [nor will I ever]
|
|
|
399 but I really need the help! See my website http://tom.iahu.ca/help_tom.html for more details. Please help
|
|
|
400 if you can!
|
|
|
401 --------------------------------------------------------------------------------------------------------------
|
|
|
402 -- Officially the library is no longer supported in GCC 3.2 in windows [cygwin].
|
|
|
403 In windows you can either use GCC 2.95.3 or try your luck with 3.2 It seems that
|
|
|
404 "-fomit-frame-pointer" is broken in the windows build [but not the linux x86 build???]
|
|
|
405 If you simply must use 3.2 then I suggest you limit the optimizations to simply "-O2"
|
|
|
406 -- Started new error handling API. Similar to the previous except there are more error codes than just
|
|
|
407 CRYPT_ERROR
|
|
|
408 -- Added my implementation of the MD2 hash function [despite the errors in the RFC I managed to get it right!]
|
|
|
409 -- Merged in more changes from Sky Schulz. I have to make mention here that he has been a tremendous help in
|
|
|
410 getting me motivated to make some much needed updates to the library!
|
|
|
411 -- Fixed one of the many mistakes in the manual as pointed out by Daniel Richards
|
|
|
412 -- Fixed a bug in the RC4 code [wasn't setting up the key correctly]
|
|
|
413 -- Added my implementation of the CAST5 [aka CAST-128] block cipher (conforms...)
|
|
|
414 -- Fixed numerous bugs in the PK code. Essentially I was "freeing" keys when the import failed. This is neither
|
|
|
415 required nor a good a idea [double free].
|
|
|
416 -- Tom needs a job.
|
|
|
417 -- Fixed up the test harness as requested by Sky Schulz. Also modifed the timing routines to run for X seconds
|
|
|
418 and count # of ops performed. This is more suitable than say encrypting 10 million blocks on a slow processor
|
|
|
419 where it could take minutes!
|
|
|
420 -- Modified test programs hashsum/encrypt to use the new algorithms and error handling syntax
|
|
|
421 -- Removed the PKCS code since it was incomplete. In the future I plan on writing a "add-on" library that
|
|
|
422 provides PKCS support...
|
|
|
423 -- updated the config system so the #defines are in the makefiles instead of mycrypt_cfg.h
|
|
|
424 -- Willing to work on an hourly basis for 15$ CDN per hour.
|
|
|
425 -- updated the test program to not test ciphers not included
|
|
|
426 -- updated the makefile to make "rsa_sys.c" a dependency of rsa.o [helps develop the code...]
|
|
|
427 -- fixed numerous failures to detect buffer overflows [minor] in the PK code.
|
|
|
428 -- fixed the safer [64-bit block version] test routines which didn't check the returns of the setup
|
|
|
429 function
|
|
|
430 -- check out my CV at http://tom.iahu.ca/cv.html
|
|
|
431 -- removed the GBA makefile and code from demos/test.c [not a particularly useful demo...]
|
|
|
432 -- merged in rudimentary [for testing] PS2 RNG from Sky Schulz
|
|
|
433 -- merged in PS2 timer code [only shell included due to NDA reasons...]
|
|
|
434 -- updated HMAC code to return errors where possible
|
|
|
435 -- Thanks go to Sky Schulz who bought me a RegCode for TextPad [the official editor of libtomcrypt]
|
|
|
436
|
|
|
437 Nov 12th, 2002
|
|
|
438 v0.70 -- Updated so you can swap out the default malloc/calloc/free routines at build time with others. (Sky Schulz)
|
|
|
439 -- Sky Schulz contributed some code towards autodetecting the PS2 in mycrypt_cfg.h
|
|
|
440 -- Added PS2 makefile contributed by Sky Schulz [see a pattern forming?]
|
|
|
441 -- Added ability to have no FILE I/O functions at all (see makefile), Sky Schulz....
|
|
|
442 -- Added support for substituting out the clock() function (Sky Schulz)
|
|
|
443 -- Fixed up makefile to include new headers in the HEADERS variable
|
|
|
444 -- Removed "coin.c" as its not really useful anyways
|
|
|
445 -- Removed many "debug" printfs that would show up on failures. Basically I wanted to ensure the only output
|
|
|
446 would be from the developer themselves.
|
|
|
447 -- Added "rc4.c" a RC4 implementation with a PRNG interface. Since RC4 isn't a block cipher it wouldn't work
|
|
|
448 too well as a block cipher.
|
|
|
449 -- Fixed ARGCHK macro usage when ARGTYPE=1 throughout the code
|
|
|
450 -- updated makefile to make subdirectory properly (Sku Schulz)
|
|
|
451 -- Started towards new API setup. Instead of checking for "== CRYPT_ERROR" you should check "!= CRYPT_OK"
|
|
|
452 In future releases functions will return things other than CRYPT_ERROR on error to give more useful
|
|
|
453 thread safe error reporting. The manual will be updated to reflect this. For this release all
|
|
|
454 errors are returned as CRYPT_ERROR (except as noted) but in future releases this will change.
|
|
|
455 -- Removed the zlib branch since its not really required anyways. Makes the package smaller
|
|
|
456
|
|
|
457 Nov 11th, 2002
|
|
|
458 v0.69 -- Added ARGCHK (see mycrypt_argchk.h) "arguement checking" to all functions that accept pointers
|
|
|
459 -- Note I forgot to change the CRYPT version tag in v0.68... fixed now.
|
|
|
460
|
|
|
461 Nov 8th, 2002
|
|
|
462 v0.68 -- Fixed flaw in kr_import/kr_export that wasted 4 bytes. Source but not binary compatible with v0.67
|
|
|
463 -- Fixed bug in kr_find_name that used memcmp to match strings. Uses strncmp now.
|
|
|
464 -- kr_clear now sets the pointer to NULL to facilate debugging [e.g. using the keyring after clearing]
|
|
|
465 -- static functions in _write/_read in keyring.c now check the return of ctr_encrypt/ctr_decrypt.
|
|
|
466 -- Updated blowfish/rc2/rc5/rc6 keysize() function to not reject keys larger than the biggest key the
|
|
|
467 respective ciphers can use.
|
|
|
468 -- Fixed a bug in hashsum demo that would report the hash for files that don't exist!
|
|
|
469
|
|
|
470 Oct 16th, 2002
|
|
|
471 v0.67 -- Moved the function prototypes into files mycrypt_*.h. To "install" the lib just copy all the
|
|
|
472 header files "*.h" from the base of this project into your global include path.
|
|
|
473 -- Made the OFB/CFB/CTR functions use "unsigned long" for the length instead of "int"
|
|
|
474 -- Added keyring support for the PK functions
|
|
|
475 -- ***API CHANGE*** changed the ecc_make_key and dh_make_key to act more like rsa_make_key. Basically
|
|
|
476 move the first argument to the next to last.
|
|
|
477 -- Fixed bug in dh_test() that wouldn't test the primality of the order of the sub-group
|
|
|
478 -- replaced the primes in the DH code with new ones that are larger than the size they are
|
|
|
479 associated with. That is a 1024-bit DH key will have a 1025-bit prime as the modulus
|
|
|
480 -- cleaned up all the PK code, changed a bit of the API around [not source compatible with v0.66]
|
|
|
481 -- major editing of the manual, started Docer program
|
|
|
482 -- added 160 and 224 bit key settings for ECC. This makes the DH and ECC binary wise incompatible with v0.66
|
|
|
483 -- Added an additional check for memory errors in is_prime() and cleaned up prime.c a bit
|
|
|
484 -- Removed ID_TAG from all files [meh, not a big fan...]
|
|
|
485 -- Removed unused variable from yarrow state and made AES/SHA256 the default cipher/hash combo
|
|
|
486 -- Fixed a bug in the Yarrow code that called prng_is_valid instead of cipher_is_valid from yarrow_start()
|
|
|
487 -- The ECB/CBC/OFB/CFB/CTR wrappers now check that the cipher is valid in the encrypt/decrypt calls
|
|
|
488 Returns int now instead of void.
|
|
|
489
|
|
|
490 Sept 24th, 2002
|
|
|
491 v0.66 -- Updated the /demos/test.c program to time the hashes correctly. Also it uses the yarrow PRNG for all of the
|
|
|
492 tests meaning its possible to run on RNG less platforms
|
|
|
493 -- Updated the /demos/hashsum.c program to hash from the standard input
|
|
|
494 -- Updated the RSA code to make keys a bit quicker [update by Wayne Scott] by not making both primes at the same
|
|
|
495 time.
|
|
|
496 -- Dan Kaminsky suggested some cleanups for the code and the MPI config
|
|
|
497 Code ships in unix LF format by default now too... will still build in MSVC and all... but if you want
|
|
|
498 to read the stuff you'll have to convert it
|
|
|
499 -- Changes to the manual to reflect new API [e.g. hash_memory/file have v0.65 prototypes]and some typos fixed
|
|
|
500
|
|
|
501 Sept 20th, 2002
|
|
|
502 v0.65 -- Wayne Scott ([email protected]) made a few of suggestions to improve the library. Most
|
|
|
503 importantly he pointed out the math lib is not really required. He's also tested the lib on 18
|
|
|
504 different platforms. According to him with only a few troubles [lack of /dev/random, etc] the
|
|
|
505 library worked as it was supposed to. You can find the list at
|
|
|
506 http://www.bitkeeper.com/Products.BitKeeper.Platforms.html
|
|
|
507 -- Updated the hash_file and hash_memory functions to keep track of the size of the output
|
|
|
508 -- Wayne Scott updated the demos/test.c file to use the SPRNG less and Yarrow more
|
|
|
509 -- Modified the mycrypt_cfg.h to autodetect x86-32 machines
|
|
|

512 v0.64 -- wrote makefile for the GBA device [and hacked the demos/test.c file to support it conditionally]
|
|
|
513 -- Fixed error in PK (e.g. ECC, RSA, DH) import functions where I was clobbering the packet error messages
|
|
|
514 -- fixed more typos in the manual
|
|
|
515 -- removed all unused variables from the core library (ignore the ID_TAG stuff)
|
|
|
516 -- added "const char *crypt_build_settings" string which is a build time constant that gives a listing
|
|
|
517 of all the build time options. Useful for debugging since you can send that to me and I will know what
|
|
|
518 exactly you had set for the mycrypt_cfg.h file.
|
|
|
519 -- Added control over endianess. Out of the box it defaults to endianess neutral but you can trivially
|
|
|
520 configure the library for your platform. Using this I boosted RC5 from 660Mbit/sec to 785Mbit/sec on my
|
|
|
521 Athlon box. See "mycrypt_cfg.h" for more information.
|
|
|

|
523 Sept 11th, 2002
|
|
|
524 v0.63 -- Made hashsum demo output like the original md5sum program
|
|
|
525 -- Made additions to the examples in the manual (fixed them up a bunch)
|
|
|
526 -- Merged in the base64 code from Wayne Scott ([email protected])
|
|
|
527
|
|
|
528 Aug 29th, 2002
|
|
|
529 v0.62 -- Added the CLEAN_STACK functionality to several of the hashes I forgot to update.
|
|
|
530
|
|
|
531 Aug 9th, 2002
|
|
|
532 v0.61 -- Fixed a bug in the DES code [oops I read something wrong].
|
|
|
533
|
|
|
534 Aug 8th, 2002
|
|
|
535 v0.60 -- Merged in DES code [and wrote 3DES-EDE code based on it] from Dobes V.
|
|
|
536
|
|
|
537 Aug 7th, 2002
|
|
|
538 v0.59 -- Fixed a "unsigned long long" bug that caused v0.58 not to build in MSVC.
|
|
|
539 -- Cleaned up a little in the makefile
|
|
|
540 -- added code that times the hash functions too in the test program
|
|
|
541
|
|
|
542 Aug 3rd, 2002
|
|
|
543 v0.58 -- Added more stack cleaning conditionals throughout the code.
|
|
|
544 -- corrected some CLEAR_STACK conditionals... should have been CLEAN_STACK
|
|
|
545 -- Simplified the RSA, DH and ECC encrypt() routines where they use CTR to encode the message
|
|
|
546 now they only make one call to ctr_encrypt()/ctr_decrypt().
|
|
|
547
|
|
|
548 Aug 2nd, 2002
|
|
|
549 v0.57 -- Fixed a few errors messages in the SAFER code to actually report the correct cipher name.
|
|
|
550 -- rsa_encrypt() uses the "keysize()" method of the cipher being used to more accurately pick a
|
|
|
551 key size. By default rsa_encrypt() will choose to use a 256-bit key but the cipher can turn that
|
|
|
552 down if required.
|
|
|
553 -- The rsa_exptmod() function will now more reliably detect invalid inputs (e.g. greater than the modulus).
|
|
|
554 -- The padding method for RSA is more clearly documented. Namely if you want to encrypt/sign something of length
|
|
|
555 N then your modulus must be of length 1+3N. So to sign a message with say SHA-384 [48 bytes] you need a
|
|
|
556 145 byte (1160 bits) modulus. This is all in the manual now.
|
|
|
557 -- Added build option CLEAN_STACK which will allow you to choose whether you want to clean the stack or not after every
|
|
|
558 cipher/hash call
|
|
|
559 -- Sped up the hash "process()" functions by not copying one byte at a time.
|
|
|
560 ++ (added just after I uploaded...)
|
|
|
561 MD4 process() now handles input buffers > 64 bytes
|
|
|
562
|
|
|
563 Aug 1st, 2002
|
|
|
564 v0.56 -- Cleaned up the comments in the Blowfish code.
|
|
|
565 -- Oh yeah, in v0.55 I made all of the descriptor elements constant. I just forgot to mention it.
|
|
|
566 -- fixed a couple of places where descriptor indexes were tested wrong. Not a huge bug but now its harder
|
|
|
567 to mess up.
|
|
|
568 -- Added the SAFER [64-bit block] ciphers K64, SK64, K128 and SK128 to the library.
|
|
|
569 -- Added the RC2 block cipher to the library.
|
|
|
570 -- Changed the SAFER define for the SAFER+ cipher to SAFERP so that the new SAFER [64-bit] ciphers
|
|
|
571 can use them with less confusion.
|
|
|
572
|
|
|
573 July 29th, 2002
|
|
|
574 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
|
|
|
575 library. Use AES or something else cuz I really hate Blowfish at this stage....
|
|
|
576 -- Partial PKCS support [hint DONT USE IT YET CUZ ITS UNTESTED!]
|
|
|
577
|
|
|
578 July 19th, 2002
|
|
|
579 v0.54 -- Blowfish now conforms to known test vectors. Silly bad coding tom!
|
|
|
580 -- RC5/RC6/Serpent all have more test vectors now [and they seemed to have been working before]
|
|
|
581
|
|
|
582 July 18th, 2002
|
|
|
583 v0.53 -- Added more test vectors to the blowfish code just for kicks [and they are const now too :-)]
|
|
|
584 -- added prng/hash/cipher is_valid functions and used them in all of the PK code so you can't enter the code
|
|
|
585 with an invalid index ever now.
|
|
|
586 -- Simplified the Yarrow code once again :-)
|
|
|
587
|
|
|
588 July 12th, 2002
|
|
|
589 v0.52 -- Fixed a bug in MD4 where the hash descriptor ID was the same as SHA-512. Now MD4 will work with
|
|
|
590 all the routines...
|
|
|
591 -- Fixed the comments in SHA-512 to be a bit more meaningful
|
|
|
592 -- In md4 I made the PADDING array const [again to store it in ROM]
|
|
|
593 -- in hash_file I switched the constant "512" to "sizeof(buf)" to be a bit safer
|
|
|
594 -- in SHA-1's test routine I fixed the string literal to say SHA-1 not sha1
|
|
|
595 -- Fixed a logical error in the CTR code which would make it skip the first IV value. This means
|
|
|
596 the CTR code from v0.52 will be incompatible [binary wise] with previous releases but it makes more
|
|
|
597 sense this way.
|
|
|
598 -- Added {} braces for as many if/for/blocks of code I could find. My rule is that every for/if/while/do block
|
|
|
599 must have {} braces around it.
|
|
|
600 -- made the rounds table in saferp_setup const [again for the ROM think about the ROM!]
|
|
|
601 -- fixed RC5 since it no longer requires rc5 to be registered in the lib. It used to since the descriptors used to
|
|
|
602 be part of the table...
|
|
|
603 -- the packet.c code now makes crypt_error literal string errors when an error occurs
|
|
|
604 -- cleaned up the SAFER+ key schedule to be a bit easier to read.
|
|
|
605 -- fixed a huge bug in Twofish with the TWOFISH_SMALL define. Because I clean the stack now I had
|
|
|
606 changed the "g_func()" to be called indirectly. I forgot to actually return the return of the Twofish
|
|
|
607 g_func() function which caused it not to work... [does now :-)]
|
|
|
608
|
|
|
609 July 11th, 2002
|
|
|
610 v0.51 -- Fixed a bug in SHA512/384 code for multi-block messages.
|
|
|
611 -- Added more test vectors to the SHA384/512 and TIGER hash functions
|
|
|
612 -- cleaned up the hash done routines to make more sense
|
|
|
613
|
|
|
614 July 10th, 2002
|
|
|
615 v0.50 -- Fixed yarrow.c so that the cipher/hash used would be registered. Also fixed
|
|
|
616 a bug where the SAFER+ name was "safer" but should have been "safer+".
|
|
|
617 -- Added an element to the hash descriptors that gives the size of a block [sent into the compressor]
|
|
|
618 -- Cleaned up the support for HMAC's
|
|
|
619 -- Cleaned up the test vector routines to make the test vector data const. This means on some platforms it will be
|
|
|
620 placed in ROM not RAM now.
|
|
|
621 -- Added MD4 code submited by Dobes Vandermeer ([email protected])
|
|
|
622 -- Added "burn_stack" function [idea taken from another source of crypto code]. The idea is if a function has
|
|
|
623 alot of variables it will clean up better. Functions like the ecb serpent and twofish code will now have their
|
|
|
624 stacks cleaned and the rest of the code is getting much more straightforward.
|
|
|
625 -- Added a hashing demo by Daniel Richards ([email protected])
|
|
|
626 -- I (Tom) modified some of the test vector routines to use more vectors ala Dobes style.
|
|
|
627 For example, the MD5/SHA1 code now uses all of the test vectors from the RFC/FIPS spec.
|
|
|
628 -- Fixed the register/unregister functions to properly report errors in crypt_error
|
|
|
629 -- Correctly updated yarrow code to remove a few unused variables.
|
|
|
630 -- Updated manual to fix a few erroneous examples.
|
|
|
631 -- Added section on Hash based Message Authentication Codes (HMAC) to the manual
|
|
|
632
|
|
|
633 June 19th, 2002
|
|
|
634 v0.46 -- Added in HMAC code from Dobes Vandermeer ([email protected])
|
|
|
635
|
|
|
636 June 8th, 2002
|
|
|
637 v0.45 -- Fixed bug in rc5.c where if you called rc5_setup() before registering RC5 it would cause
|
|
|
638 undefined behaviour.
|
|
|
639 -- Fixed mycrypt_cfg.h to eliminate the 224 bit ECC key.
|
|
|
640 -- made the "default" makefile target have depends on mycrypt.h and mycrypt_cfg.h
|
|
|
641
|
|
|
642 Apr 4th, 2002
|
|
|
643 v0.44 -- Fixed bug in ecc.c::new_point() where if the initial malloc fails it would not catch it.
|
|
|
644
|
|
|
645 Mar 22nd, 2002
|
|
|
646 v0.43 -- Changed the ZLIB code over to the 1.1.4 code base to avoid the "double free" bug.
|
|
|
647 -- Updated the GCC makefile not to use -O3 or -funroll-loops
|
|
|
648 -- Version tag in mycrypt.h has been updated :-)
|
|
|
649
|
|
|
650 Mar 10th, 2002
|
|
|
651 v0.42 -- The RNG code can now use /dev/urandom before trying /dev/random (J. Klapste)
|
|
|
652
|
|
|
653 Mar 3rd, 2002
|
|
|
654 v0.41 -- Added support to link and use ciphers at compile time. This can greatly reduce the code size!
|
|
|
655 -- Added a demo to show off how small an application can get... 46kb!
|
|
|
656 -- Disastry pointed out that Blowfish is supposed to be high endian.
|
|
|
657 -- Made registry code for the PRNGs as well [now the smallest useable link is 43kb]
|
|
|
658
|
|
|
659 Feb 11th, 2002
|
|
|
660 v0.40 -- RSA signatures use [and check for] fixed padding scheme.
|
|
|
661 -- I'm developing in Linux now :-)
|
|
|
662 -- No more warnings from GCC 2.96
|
|
|
663
|
|
|
664 Feb 5th, 2002
|
|
|
665 v0.39 -- Updated the XTEA code to work in accordance with the XTEA design
|
|
|
666
|
|
|
667 January 24th, 2002
|
|
|
668 v0.38 -- CFB and OFB modes can now handle blocks of variable size like the CTR code
|
|
|
669 -- Wrote a wrapper around the memory compress functions in Zlib that act like the functions
|
|
|
670 in the rest of my crypto lib
|
|
|
671
|
|
|
672 January 23rd, 2002
|
|
|
673 v0.37 -- Added support code so that if a hash size and key size for a cipher don't match up they will
|
|
|
674 use the next lower key supported. (mainly for the PK code). So you can now use SHA-1 with
|
|
|
675 Twofish, etc...
|
|
|
676 -- Added more options for Twofish. You can now tell it to use precomputed sboxes and MDS multiplications
|
|
|
677 This will speed up the TWOFISH_SMALL implementation by increasing the code size by 1024 bytes.
|
|
|
678 -- Fixed a bug in prime.c that would not use the correct table if you undefined SMALL_PRIME_TAB
|
|
|
679 -- Fixed all of the PK packet code to use the same header format [see packet.c]. This makes the PK code
|
|
|
680 binary wise incompatible with previous releases while the API has not changed at all.
|
|
|
681
|
|
|
682 January 22nd, 2002
|
|
|
683 v0.36 -- Corrections to the manual
|
|
|
684 -- Made a modification to Twofish which lets you build a "small ram" variant. It requires
|
|
|
685 about 190 bytes of ram for the key storage compared to the 4,200 bytes the normal
|
|
|
686 variant requires.
|
|
|
687 -- Reduced the stack space used in all of the PK routines.
|
|
|
688
|
|
|
689 January 19th, 2002
|
|
|
690 v0.35 -- If you removed the first hash or cipher from the library it wouldn't return an error if
|
|
|
691 you used an ID=0 [i.e blowfish or sha256] in any routine. Now it checks for that and will
|
|
|
692 return an error like it should
|
|
|
693 -- Merged in new routines from Clay Culver. These routines are for the PK code so you can easily
|
|
|
694 encode a symmetric key for multiple recipients.
|
|
|
695 -- Made the ecc and DH make_key() routines make secret keys of the same size as the keysize listed.
|
|
|
696 Originally I wanted to ensure that the keys were smaller than the order of the field used
|
|
|
697 However, the bias is so insignifcant using full sizes. For example, with a ECC-192 key the order
|
|
|
698 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
|
|
|
699 key the code will work just the same except that some 192-bit keys will be duplicates which is not a big
|
|
|
700 deal since 1/2^192 is a very small bias!
|
|
|
701 -- Made the configuration a bit simpler and more exacting. You can for example now select which DH or ECC
|
|
|
702 key settings you wish to support without including the data for all other key settings. I put the #defines
|
|
|
703 in a new file called "mycrypt_cfg.h"
|
|
|
704 -- Configured "mpi-config.h" so its a bit more conservative with the memory required and code space used
|
|
|
705 -- Jason Klapste submitted bug fixes to the yarrow, hash and various other issues. The yarrow code will now
|
|
|
706 use what ever remaining hash/cipher combo is left [after you #undef them] at build time. He also suggested
|
|
|
707 a fix to remove unused structures from the symmetric_key and hash_state unions.
|
|
|
708 -- Made the CTR code handle variable length blocks better. It will buffer the encryption pad so you can
|
|
|
709 encrypt messages any size block at a time.
|
|
|
710 -- Simplified the yarrow code to take advantage of the new CTR code.
|
|
|
711 -- Added a 4096-bit DH key setting. That took me about 36 hours to find!
|
|
|
712 -- Changed the base64 routines to use a real base64 encoding scheme.
|
|
|
713 -- Added in DH and ECC "encrypt_key()" functions. They are still rather "beta"ish.
|
|
|
714 -- Added **Twofish** to the list of ciphers!
|
|
|
715
|
|
|
716 January 18th, 2002
|
|
|
717 v0.34 -- Added "sha512" to the list of hashes. Produces a 512-bit message digest. Note that with the current
|
|
|
718 padding with the rsa_sign() function you cannot use sha512 with a key less than 1536 bits for signatures.
|
|
|
719 -- Cleaned up the other hash functions to use the LOAD and STORE macros...
|
|
|
720
|
|
|
721 January 17th, 2002
|
|
|
722 v0.33 -- Made the lower limit on keysizes for RSA 1024 bits again because I realized that 768 bit keys wouldn't
|
|
|
723 work with the padding scheme and large symmetric keys.
|
|
|
724 -- Added information concerning the Zlib license to the manual
|
|
|
725 -- Added a 3072-bit key setting for the DH code.
|
|
|
726 -- Made the "find_xyz()" routines take "const char *" as per Clay Culver's suggestion.
|
|
|
727 -- Fixed an embarassing typo in the manual concerning the hashes. Thank's Clay for finding it!
|
|
|
728 -- Fixed rand_prime() so that it makes primes bigger than the setting you give. For example,
|
|
|
729 if you want a 1024-bit prime it would make a 1023-bit one. Now it ensures that the prime
|
|
|
730 it makes is always greater than 2^(8n) (n == bytes in prime). This doesn't have a huge
|
|
|
731 impact on security but I corrected it just the same.
|
|
|
732 -- Fixed the CTR routine to work on platforms where char != 8-bits
|
|
|
733 -- Fixed sha1/sha256/md5/blowfish to not assume "unsigned long == 32-bits", Basically any operation with carries
|
|
|
734 I "AND" with 0xFFFFFFFF. That forces only the lower 32-bits to have information in it. On x86 platforms
|
|
|
735 most compilers optimize out the AND operation since its a nop.
|
|
|
736
|
|
|
737 January 16th, 2002
|
|
|
738 v0.32 -- Made Rijndael's setup function fully static so it is thread safe
|
|
|
739 -- Svante Seleborg suggested a cosmetic style fixup for aes.c,
|
|
|
740 basically to remove some of the #defines to clean it up
|
|
|
741 -- Made the PK routines not export the ASCII version of the names of ciphers/hashes which makes
|
|
|
742 the PK message formats *incompatible* with previous releases.
|
|
|
743 -- Merge in Zlib :-)
|
|
|
744
|
|
|
745
|
|
|
746 January 15th, 2002
|
|
|
747 v0.31 -- The RSA routines can now use CRT to speed up decryption/signatures. The routines are backwards
|
|
|
748 compatible with previous releases.
|
|
|
749 -- Fixed another bug that Svante Seleborg found. Basically you could buffer-overrun the
|
|
|
750 rsa_exptmod() function itself if you're not careful. That's fixed now. Fixed another bug in
|
|
|
751 rsa_exptmod() where if it knows the buffer you passed is too small it wouldn't free all used
|
|
|
752 memory.
|
|
|
753 -- improved the readability of the PK import/export functions
|
|
|
754 -- Added a fix to RSA.C by Clay Culver
|
|
|
755 -- Changed the CONST64 macro for MSVC to use the "unsigned __int64" type, e.g. "ui64" instead of "i64".
|
|
|
756
|
|
|
757 January 14th, 2002
|
|
|
758 v0.30 -- Major change to the Yarrow PRNG code, fixed a bug that Eugene Starokoltsev found.
|
|
|
759 Basically if you added entropy to the pool in small increments it could in fact
|
|
|
760 cancel out. Now I hash the pool with the new data which is way smarter.
|
|
|
761
|
|
|
762 January 12th, 2002
|
|
|
763 v0.29 -- Added MPI code written by Svante Seleborg to the library. This will make the PK code much
|
|
|
764 easier to follow and debug. Actually I've already fixed a memory leak in dh_shared_secret().
|
|
|
765 -- Memory leaks found and correct in all three PK routines. The leaks would occur when a bignum
|
|
|
766 operation fails so it wouldn't normally turn up in the course of a program
|
|
|
767 -- Fixed bugs in dh_key_size and ecc_key_size which would return garbage for invalid key idx'es
|
|
|
768
|
|
|
769 January 11th, 2002
|
|
|
770 v0.28 -- Cleaned up some code so that it doesn't assume "char == 8bits". Mainly SAFER+ has been
|
|
|
771 changed.
|
|
|
772 -- ***HUGE*** changes in the PK code. I check all return values in the bignum code so if there
|
|
|
773 are errors [insufficient memory, etc..] it will be reported. This makes the code fairly more
|
|
|
774 robust and likely to catch any errors.
|
|
|
775 -- Updated the is_prime() function to use a new prototype [it can return errors now] and it also
|
|
|
776 does trial divisions against more primes before the Rabin Miller steps
|
|
|
777 -- Added OFB, CFB and ECB generic wrappers for the symmetric ciphers to round out the implementations.
|
|
|
778 -- Added Xtea to the list of ciphers, to the best of my ability I have verified this implementation.
|
|
|
779 I should note that there is not alot of concrete information about the cipher. "Ansi C" versions
|
|
|
780 I found did not address endianess and were not even portable!. This code is portable and to the
|
|
|
781 best of my knowledge implements the Xtea algorithm as per the [short] X-Tea paper.
|
|
|
782 -- Reformated the manual to include the **FULL** source code optimized to be pritable.
|
|
|
783
|
|
|
784 January 9th, 2002
|
|
|
785 v0.27 -- Changed the char constants to numerical values. It is backwards compatible and should work on
|
|
|
786 platforms where 'd' != 100 [for example].
|
|
|
787 -- Made a change to rand_prime() which takes the input length as a signed type so you can pass
|
|
|
788 a negative len to get a "3 mod 4" style prime... oops
|
|
|
789 -- changed the MSVC makefile to build with a warning level of three, no warnings!
|
|
|
790
|
|
|
791 January 8th, 2002
|
|
|
792 v0.26 -- updated SHA-256 to use ROR() for a rotate so 64-bit machines won't corrupt
|
|
|
793 the output
|
|
|
794 -- Changed #include <> to #include "" for local .h files as per Richard Heathfields' suggestions.
|
|
|
795 -- Fixed bug in MPI [well bug in MSVC] that compiled code incorrectly in mp_set_int()
|
|
|
796 I added a work around that catches the error and continues normally.
|
|
|
797
|
|
|
798 January 8th, 2002
|
|
|
799 v0.25 -- Added a stupid define so MSVC 6.00 can build the library.
|
|
|
800 -- Big thanks to sci.crypt and "Ajay K. Agrawal" for helping me port this to MSVC
|
|
|
801
|
|
|
802 January 7th, 2002
|
|
|
803 v0.24 -- Sped up Blowfish by unrolling and removing the swaps.
|
|
|
804 -- Made the code comply with more traditional ANSI C standards
|
|
|
805 Should compile with MSVC with less errors
|
|
|
806 -- moved the demos and documentation into their own directories
|
|
|
807 so you can easily build the library with other tool chains
|
|
|
808 by compiling the files in the root
|
|
|
809 -- converted functions with length of outputs to use
|
|
|
810 "unsigned long" so 16-bit platforms will like this library more.
|
|
|
811
|
|
|
812 January 5th, 2002
|
|
|
813 v0.23 -- Fixed a small error in the MPI config it should build fine anywhere.
|
|
|
814
|
|
|
815 January 4th, 2002
|
|
|
816 v0.22 -- faster gf_mul() code
|
|
|
817 -- gf_shl() and gf_shr() are safe on 64-bit platforms now
|
|
|
818 -- Fixed an error in the hashes that Brian Gladman found.
|
|
|
819 Basically if the message has exactly 56 bytes left to be
|
|
|
820 compressed I handled them incorrectly.
|
|
|
821
|
|
|
822 January 4th, 2002
|
|
|
823 v0.21 -- sped up the ECC code by removing redundant divisions in the
|
|
|
824 point add and double routines. I also extract the bits more
|
|
|
825 efficiently in "ecc_mulmod()" now.
|
|
|
826 -- sped up [and documented] the rand_prime() function. Now it just
|
|
|
827 makes a random integer and increments by two until a prime is found
|
|
|
828 This is faster since it doesn't require alot of calls to the PRNG and
|
|
|
829 it doesn't require loading huge integers over and over. rand_prime()
|
|
|
830 can also make primes congruent to 3 mod 4 [i.e for a blum integer]
|
|
|
831 -- added a gf_sqrt() function that finds square roots in a GF(2^w) field
|
|
|
832 -- fixed a bug in gf_div() that would return the wrong results if the divisor had a greator
|
|
|
833 divisor than the dividend.
|
|
|
834
|
|
|
835 January 4th, 2002
|
|
|
836 v0.20 -- Added the fixed MPI back in so RSA and DH are much faster again
|
|
|
837
|
|
|
838 v0.19 -- Updated the manual to reflect the fact that Brian Gladman wrote the AES and Serpent code.
|
|
|
839 -- DH, ECC and RSA signature/decryption functions check if the key is private
|
|
|
840 -- new DH signature/verification code works just like the RSA/ECC versions
|
|
|
841
|
|
|
842 January 3rd, 2002
|
|
|
843 v0.18 -- Added way more comments to each .C file
|
|
|
844 -- fixed a bug in cbc_decrypt(pt, ct, key) where pt == ct [i.e same buffer]
|
|
|
845 -- fixed RC5 so it reads the default rounds out of the cipher_descriptor table
|
|
|
846 -- cleaned up ecc_export()
|
|
|
847 -- Cleaned up dh_import() and ecc_import() which also perform more
|
|
|
848 error checking now
|
|
|
849 -- Fixed a serious flaw in rsa_import() with private keys.
|
|
|
850
|
|
|
851 January 2nd, 2002
|
|
|
852 v0.17 -- Fixed a bug in the random prime generator that fixes the wrong bits to one
|
|
|
853 -- ECC and DH code verify that the moduli and orders are in fact prime. That
|
|
|
854 slows down the test routines alot but what are you gonna do?
|
|
|
855 -- Fixed a huge bug in the mp_exptmod() function which incorrectly calculates g^x mod p for some
|
|
|
856 values of p. I replaced it with a slow function. Once the author of MPI fixes his faster routine
|
|
|
857 I will switch back.
|
|
|
858
|
|
|
859 January 1st, 2002 [whoa new year!]
|
|
|
860 v0.16 -- Improved GF division code that is faster.
|
|
|
861 -- documented the GF code
|
|
|
862
|
|
|
863 December 31st, 2001
|
|
|
864 v0.15 -- A 1792-bit and 2048-bit DH setting was added. Took me all night to
|
|
|
865 find a 1792 and 2048-bit strong prime but what the heck
|
|
|
866 -- Library now has polynomial-basis GF(2^w) routines I wrote myself. Can be used to perform
|
|
|
867 ECC over GF(2^w) later on....
|
|
|
868 -- Fixed a bug with the defines that allows it to build in windows
|
|
|
869
|
|
|
870 December 30th, 2001
|
|
|
871 v0.14 -- Fixed the xxx_encrypt() packet routines to make an IV of appropriate size
|
|
|
872 for the cipher used. It was defaulting to making a 256-bit IV...
|
|
|
873 -- base64_encode() now appends a NULL byte, um "duh" stupid mistake now fixed...
|
|
|
874 -- spell checked the manual again... :-)
|
|
|
875
|
|
|
876 December 30th, 2001
|
|
|
877 v0.13 -- Switching back to older copy of MPI since it works! arrg..
|
|
|
878 -- Added sign/verify functions for ECC
|
|
|
879 -- all signature verification routines default to invalid signatures.
|
|
|
880 -- Changed all calls to memset to zeromem. Fixed up some buffer problems
|
|
|
881 in other routines. All calls to zeromem let the compiler determine the size
|
|
|
882 of the data to wipe.
|
|
|
883
|
|
|
884 December 29th, 2001
|
|
|
885 v0.12 -- Imported a new version of MPI [the bignum library] that should
|
|
|
886 be a bit more stable [if you want to write your own bignum
|
|
|
887 routines with the library that is...]
|
|
|
888 -- Manual has way more info
|
|
|
889 -- hash_file() clears stack now [like it should]
|
|
|
890 -- The artificial cap on the hash input size of 2^32 bits has been
|
|
|
891 removed. Basically I was too lazy todo 64-bit math before
|
|
|
892 [don't ask why... I can't remember]. Anyways the hashes
|
|
|
893 support the size of 2^64 bits [if you ever use that many bits in a message
|
|
|
894 that's just wierd...]
|
|
|
895 -- The hashes now wipe the "hash_state" after the digest is computed. This helps
|
|
|
896 prevent the internal state of the hash being leaked accidently [i.e stack problems]
|
|
|
897
|
|
|
898 December 29th, 2001
|
|
|
899 v0.11 -- Made #define's so you can trim the library down by removing
|
|
|
900 ciphers, hashs, modes of operation, prngs, and even PK algorithms
|
|
|
901 For example, the library with rijndael+ctr+sha1+ECC is 91KB compared
|
|
|
902 to the 246kb the full library takes.
|
|
|
903 -- Added ECC packet routines for encrypt/decrypt/sign/verify much akin to
|
|
|
904 the RSA packet routines.
|
|
|
905 -- ECC now compresses the public key, a ECC-192 public key takes 33 bytes
|
|
|
906 for example....
|
|
|
907
|
|
|
908 December 28th, 2001
|
|
|
909 v0.10 -- going to restart the manual from scratch to make it more
|
|
|
910 clear and professional
|
|
|
911 -- Added ECC over Z/pZ. Basically provides as much as DH
|
|
|
912 except its faster since the numbers are smaller. For example,
|
|
|
913 A comparable 256-bit ECC key provides as much security as expected
|
|
|
914 from a DH key over 1024-bits.
|
|
|
915 -- Cleaned up the DH code to not export the symbol "sets[]"
|
|
|
916 -- Fixed a bug in the DH code that would not make the correct size
|
|
|
917 random string if you made the key short. For instance if you wanted
|
|
|
918 a 512-bit DH key it would make a 768-bit one but only make up 512-bits
|
|
|
919 for the exponent... now it makes the full 768 bits [or whatever the case
|
|
|
920 is]
|
|
|
921 -- Fixed another ***SERIOUS*** bug in the DH code that would default to 768-bit
|
|
|
922 keys by mistake.
|
|
|
923
|
|
|
924 December 25th, 2001
|
|
|
925 v0.09 -- Includes a demo program called file_crypt which shows off
|
|
|
926 how to use the library to make a command line tool which
|
|
|
927 allows the user to encode/decode a file with any
|
|
|
928 hash (on the passphrase) and cipher in CTR mode.
|
|
|
929 -- Switched everything to use typedef's now to clear up the code.
|
|
|
930 -- Added AES (128/192 and 256 bit key modes)
|
|
|
931
|
|
|
932 December 24th, 2001
|
|
|
933 v0.08 -- fixed a typo in the manual. MPI stores its bignums in
|
|
|
934 BIG endian not little.
|
|
|
935 -- Started adding a RNG to the library. Right now it tries
|
|
|
936 to open /dev/random and if that fails it uses either the
|
|
|
937 MS CSP or the clock drift RNG. It also allows callbacks
|
|
|
938 since the drift RNG is slow (about 3.5 bytes/sec)
|
|
|
939 -- the RNG can also automatically setup a PRNG as well now
|
|
|
940
|
|
|
941 v0.07 -- Added basic DH routines sufficient to
|
|
|
942 negotiate shared secrets
|
|
|
943 [see the manual for a complete example!]
|
|
|
944 -- Fixed rsa_import to detect when the input
|
|
|
945 could be corrupt.
|
|
|
946 -- added more to the manual.
|
|
|
947
|
|
|
948 December 22nd, 2001
|
|
|
949 v0.06 -- Fixed some formatting errors in
|
|
|
950 the hash functions [just source code cleaning]
|
|
|
951 -- Fixed a typo in the error message for sha256 :-)
|
|
|
952 -- Fixed an error in base64_encode() that
|
|
|
953 would fail to catch all buffer overruns
|
|
|
954 -- Test program times the RSA and symmetric cipher
|
|
|
955 routines for kicks...
|
|
|
956 -- Added the "const" modifier to alot of routines to
|
|
|
957 clear up the purpose of each function.
|
|
|
958 -- Changed the name of the library to "TomCrypt"
|
|
|
959 following a suggestion from a sci.crypt reader....
|
|
|
960
|
|
|
961 v0.05 -- Fixed the ROL/ROR macro to be safe on platforms
|
|
|
962 where unsigned long is not 32-bits
|
|
|
963 -- I have added a bit more to the documentation
|
|
|
964 manual "crypt.pdf" provided.
|
|
|
965 -- I have added a makefile for LCC-Win32. It should be
|
|
|
966 easy to port to other LCC platforms by changing a few lines.
|
|
|
967 -- Ran a spell checker over the manual.
|
|
|
968 -- Changed the header and library from "crypt" to "mycrypt" to not
|
|
|
969 clash with the *nix package "crypt".
|
|
|
970
|
|
|
971 v0.04 -- Fixed a bug in the RC5,RC6,Blowfish key schedules
|
|
|
972 where if the key was not a multiple of 4 bytes it would
|
|
|
973 not get loaded correctly.
|
|
|
974
|
|
|
975 December 21st, 2001
|
|
|
976
|
|
|
977 v0.03 -- Added Serpent to the list of ciphers.
|
|
|
978
|
|
|
979 v0.02 -- Changed RC5 to only allow 12 to 24 rounds
|
|
|
980 -- Added more to the manual.
|
|
|
981
|
|
|
982 v0.01 -- We will call this the first version.
|
