| 70 |
to access the old algorithm used use the "blowfish-compat" module. |
| 71 |
- Fixes in mcrypt_list_algorithms() for some systems. Bugs pointed out by |
| 72 |
Jonathan Woolmington <jwool@ind.tansu.com.au> |
| 73 |
- Fixes in stream mode. |
| 74 |
- mcrypt_generic_init() no longer fails if smaller key is used. It uses |
| 75 |
the most appropriate key size of the algorithm and pads with zeros. |
| 76 |
- Fixes in wake algorithm (and support for IV). |
| 77 |
- IV is now used in arcfour (arcfour-iv is now longer used). Speedups in Arcfour. |

| 108 |
- Libmcrypt is no longer compatible with 2.2 or 2.3 version. |
| 109 |
- Speedups in the library. |
| 110 |
- The crypt algorithm has changed. In order for it's output to be compatible |
| 111 |
with the unix crypt output, the key must be generated using crypt(3). |
| 112 |
This was made in order to remove the key transformation, which was |
| 113 |
included in the algorithm. |
| 114 |
- The crypt algorithm was renamed to enigma. |
| 115 |
- Changed many function's names in order to minimize namespace polution. |

| 145 |
|
| 146 |
January 20th, 2000: (version 2.3.0) |
| 147 |
- Tried to include libltdl. Not succesful yet. It compiles but it does |
| 148 |

| 175 |
machines. |
| 176 |
|
| 177 |
November 29th, 1999: |
| 178 |
- encrypt() function crypt.c was renamed to __encrypt() in order to compile |
| 179 |
in some systems. |
| 180 |
- version number is included in the modules. |
| 181 |
- mcrypt_list_algorithms(), mcrypt_list_modes() and mcrypt_list_keygen() now |
| 182 |
check if the file is an mcrypt module (has the _mcrypt_xxx_version function). |
| 183 |
|
| 184 |
November 28th, 1999: |
| 185 |

name. |
| 192 |
- Documentation was updated. |
| 193 |

| 200 |
|
| 201 |
November 24th, 1999: |
| 202 |
- sdes key generation module was corrected. Now it works fine with |
| 203 |
des(1). |
| 204 |
|
| 205 |
November 20th, 1999: |
| 206 |
- Mcrypt is now modular. Modes, algorithm, and key generation modules, can |

| 209 |
November 17th, 1999: |
| 210 |

| 211 |
- WAKE stream algorithm was added (experimental). |
| 212 |
|
| 213 |
November 13th, 1999: |
| 214 |
- Blowfish algorithm was changed, it is now compatible with other implementations. |
| 215 |
- Accessing algorithms is now different. You do not specify TWOFISH_256, to |
| 216 |
access TWOFISH algorithm with 256 bit key, but TWOFISH with keylength of |
| 217 |
32 bytes (==256 bits). This is more flexible than the previous API since |
| 218 |
you can access more keys. |
| 219 |
|
| 220 |

| 241 |
|
| 242 |
September 20th, 1999: |
| 243 |

| 244 |
big-endian and little-endian machines. |
| 245 |
- Porting of SERPENT, MARS and RIJNDAEL is not ready, they do |
| 246 |
not work right in bigendian machines. |
| 247 |
- Bugfixes in the tests. Tests failed if one or two algorithms failed. |
| 248 |
|
| 249 |
September 19th, 1999 |
| 250 |
- SERPENT was added in 128,192,256 key modes. |
| 251 |
|
| 252 |
September 15th, 1999 |
| 253 |
- MARS and RIJNDAEL were added in 128,192,256 key modes. |
| 254 |
- RC6 was splitted to RC6_128, RC6_192 and RC6_256 (the old RC6 is equal to RC6_256) |
| 255 |
- RC2 was splitted to RC2_128, RC2_256 and RC2_1024 (the old RC2 is equal to RC2_1024) |
| 256 |
|
| 257 |
September 14th, 1999 |
| 258 |
- Twofish code was changed. Now it uses Dr Brian Gladman's code. |
| 259 |
- RC2 code was changed. |
| 260 |
|
| 261 |
June 26th, 1999 |
| 262 |

| 263 |
|
| 264 |
June 23th, 1999 |
| 265 |
- RC2 code was cleared. |
| 266 |
- RC6 was changed according to the specification. It is RC6 32/20/32. |
| 267 |
RC6, SAFER+, LOKI97 and CAST-256 codes are actually Dr Brian Gladman's |
| 268 |
code a bit modified for mcrypt. |
| 269 |
- shared library version has changed (at last!) |
| 270 |
|
| 271 |
June 22th, 1999 |
| 272 |
- SAFER+, LOKI97 and CAST-256 Added. |
| 273 |
|
| 274 |
June 15th, 1999 - Version 2.2 |
| 275 |
- Changes in the xTEA algorithm. Some extra parenthesis made the algorithm |
| 276 |
differ from the specification. Pointed out by Lars Nordentoft |
| 277 |
<lntech@post9.tele.dk>. Read the README.xtea for more information. |
| 278 |
|
| 279 |
June 12th, 1999 - Version 2.1.1 |
| 280 |
- Changes in the documentation which was inaccurate. |
| 281 |
|
| 282 |
June 11th, 1999 - Version 2.1 |
| 283 |
- _mcrypt_ was placed as a prefix to all internal functions so they |
| 284 |
do not pollute namespace. |
| 285 |
|
| 286 |
May 29th, 1999 |
| 287 |
- test suites added |
| 288 |
- Blowfish was divided to blowfish-448, -256, -192, -128. |
| 289 |
- CBC can now accept IV |
| 290 |
- mlock and munlock is used before mallocing and freeing any memory, |
| 291 |
thus if such capabilities exist the library guarrantees that no |
| 292 |
password is written in the disk (as swap etc.) |
| 293 |
- gen_key_md5() was added and gen_key() was renamed to gen_key_sha1() |
| 294 |
gen_key() is still defined to be gen_keysha1(). |
| 295 |
|
| 296 |
May 26th, 1999 - Version 2.0 |
| 297 |
- Documentation was incorrect and innacurate. Corrected. |
| 298 |
- A #define WORDS_BIGENDIAN 0 was removed from acconfig.h, this |
| 299 |
was confusing all the library headers, and thus the library was |
| 300 |
useless. |
| 301 |
- nbit-ofb mode added. n is the blocksize of the algorithm. Still |
| 302 |
experimental. |
| 303 |
|
| 304 |
May 24th, 1999 - Version 1.93 |
| 305 |
- defined get_block_size to be mcrypt_get_block_size so php3.0.8 compiles ok |
| 306 |
|
| 307 |
May 17th, 1999 - Version 1.9 |
| 308 |
- gen_key() changed |
| 309 |
- libtool support (based on Sascha Schumann's patches) |
