Revision 1.49 - (show annotations)
Tue Dec 17 14:31:40 2002 UTC (21 years, 3 months ago) by nmav
Branch: MAIN
Changes since 1.48: +3 -2 lines
Added mcrypt_module_support_dynamic(), and some more fixes to disable dynamic loading.

1 xxx xx xxxx: (version 2.5.4)
2 - Better win32 detection and DLL building.
3 - Changed some variables names in gost.c to allow compiling
4 with gcc and K6 optimizations.
5 - Some buffer overrun checks on input. Patches and suggestions
6 by Ilia A. <ilia@prohost.org>
7 - Made the default behaviour to include all algorithms into
8 the main library, instead of using dynamic modules. Dynamic
9 loading is disabled by default. The --enable-dynamic-loading flag
10 can be used in the configure script, to get the old behaviour.
11

100 the most appropriate key size of the algorithm and pads with zeros.
101 - Fixes in wake algorithm (and support for IV).
102 - IV is now used in arcfour (arcfour-iv is now longer used). Speedups in Arcfour.
103 - mcrypt_generic_deinit() function added.

132 - Libmcrypt is now thread safe without need for posix thread locks.
133 - Libmcrypt is no longer compatible with 2.2 or 2.3 version.
134 - Speedups in the library.
135 - The crypt algorithm has changed. In order for it's output to be compatible
136 with the unix crypt output, the key must be generated using crypt(3).
137 This was made in order to remove the key transformation, which was
138 included in the algorithm.
139 - The crypt algorithm was renamed to enigma.
140 - Changed many function's names in order to minimize namespace polution.
141 View the manpage for more information.

143 March 4th, 2000: (version 2.3.4)
144 - Improved POSIX Threads detection by Sascha Schumann
145 - Arcfour was renamed to arcfour-iv. The arcfour algorithm now does not
146 support iv (as the original algorithm does).
147 - Modes for block algorithms are not limited any more to a 256 bit block size.
148 - Mcrypt 2.2 compatibility functions were added.

153 - Some dlsyms were cached causing a 50% increase in speed.
154
155 February 27th, 2000:
156 - A slightly modified version of libmcrypt 2.2.4 was released in order
157 for mcrypt 2.5.0 to be able to compile against that series of libmcrypt.
158
159 February 22, 2000:
160 - mcrypt_is_block_algorithm_mode(), mcrypt_is_block_mode(),
161 mcrypt_is_block_algorithm(), functions were added.
162 - Bugfixes in the mcrypt_module_self_test().
163
164 February 8th, 2000:
165 - Keygen functionality was added to the cvs version of libmhash.
166 Libmcrypt seems to compile fine.
167
168 January 21st, 2000:
169 - Locks were added to libltdl calls so libmcrypt is still thread safe.
170
171 January 20th, 2000: (version 2.3.0)
172 - Tried to include libltdl. Not succesful yet. It compiles but it does
173 not work.
174 - keygen functionality was removed. It will be added to libmhash
175 http://schumann.cx/mhash
176
177 January 13th, 2000:
178 - Changed the sha-1 algorithm implementation

199 - Corrections in the panama algorithm, in order to work fine in big-endian
200 machines.
201
202 November 29th, 1999:
203 - encrypt() function crypt.c was renamed to __encrypt() in order to compile
204 in some systems.
205 - version number is included in the modules.
206 - mcrypt_list_algorithms(), mcrypt_list_modes() and mcrypt_list_keygen() now
207 check if the file is an mcrypt module (has the _mcrypt_xxx_version function).
208
209 November 28th, 1999:
210 - MARS was added (as a separate module)
211
212 November 26th, 1999:

221 __setkey() to keep some libcs happy.
222 - Corrected typo mistakes in twofish.c.
223 - Patched wake.c to work in bigendian machines.
224 - IDEA, RC4, RC6 which were non-free now are in a separate distribution.
225
226 November 24th, 1999:

228 des(1).
229
230 November 20th, 1999:

240 - Accessing algorithms is now different. You do not specify TWOFISH_256, to
241 access TWOFISH algorithm with 256 bit key, but TWOFISH with keylength of
242 32 bytes (==256 bits). This is more flexible than the previous API since
243 you can access more keys.
244
245 October 16th, 1999:
246 - The new API is completed.
247 - STREAM mode was added.
248 - RC4 was added.

266
267 September 20th, 1999:
268 - Fixes in RC2, RC6 and SAFER+ code, so they work the same way in
269 big-endian and little-endian machines.
270 - Porting of SERPENT, MARS and RIJNDAEL is not ready, they do
271 not work right in bigendian machines.
272 - Bugfixes in the tests. Tests failed if one or two algorithms failed.
273
274 September 19th, 1999
275 - SERPENT was added in 128,192,256 key modes.
276
277 September 15th, 1999
278 - MARS and RIJNDAEL were added in 128,192,256 key modes.
279 - RC6 was splitted to RC6_128, RC6_192 and RC6_256 (the old RC6 is equal to RC6_256)
280 - RC2 was splitted to RC2_128, RC2_256 and RC2_1024 (the old RC2 is equal to RC2_1024)
281
282 September 14th, 1999
283 - Twofish code was changed. Now it uses Dr Brian Gladman's code.
284 - RC2 code was changed.
285
286 June 26th, 1999
287 - buffer overflow fixed in lib/mcrypt.c. Pointed out by Don Sutherland <dss@yadda.net>
288
289 June 23th, 1999
290 - RC2 code was cleared.
291 - RC6 was changed according to the specification. It is RC6 32/20/32.
292 RC6, SAFER+, LOKI97 and CAST-256 codes are actually Dr Brian Gladman's
293 code a bit modified for mcrypt.
294 - shared library version has changed (at last!)
295
296 June 22th, 1999
297 - SAFER+, LOKI97 and CAST-256 Added.
298
299 June 15th, 1999 - Version 2.2
300 - Changes in the xTEA algorithm. Some extra parenthesis made the algorithm
301 differ from the specification. Pointed out by Lars Nordentoft
302 <lntech@post9.tele.dk>. Read the README.xtea for more information.
303
304 June 12th, 1999 - Version 2.1.1
305 - Changes in the documentation which was inaccurate.
306
307 June 11th, 1999 - Version 2.1
308 - _mcrypt_ was placed as a prefix to all internal functions so they
309 do not pollute namespace.
310
311 May 29th, 1999
312 - test suites added
313 - Blowfish was divided to blowfish-448, -256, -192, -128.
314 - CBC can now accept IV
315 - mlock and munlock is used before mallocing and freeing any memory,
316 thus if such capabilities exist the library guarrantees that no
317 password is written in the disk (as swap etc.)
318 - gen_key_md5() was added and gen_key() was renamed to gen_key_sha1()
319 gen_key() is still defined to be gen_keysha1().
320
321 May 26th, 1999 - Version 2.0
322 - Documentation was incorrect and innacurate. Corrected.
323 - A #define WORDS_BIGENDIAN 0 was removed from acconfig.h, this
324 was confusing all the library headers, and thus the library was
325 useless.
326 - nbit-ofb mode added. n is the blocksize of the algorithm. Still
327 experimental.
328
329 May 24th, 1999 - Version 1.93
330 - defined get_block_size to be mcrypt_get_block_size so php3.0.8 compiles ok
331
332 May 17th, 1999 - Version 1.9
333 - gen_key() changed
334 - libtool support (based on Sascha Schumann's patches)
