with the unix crypt output, the key must be generated using crypt(3).
This was made in order to remove the key transformation, which was
included in the algorithm.
- The crypt algorithm was renamed to enigma.
- Changed many function's names in order to minimize namespace polution.
View the manpage for more information.
March 4th, 2000: (version 2.3.4)

- Locks were added to libltdl calls so libmcrypt is still thread safe.
January 20th, 2000: (version 2.3.0)

not work.

http://schumann.cx/mhash
January 13th, 2000:
- Changed the sha-1 algorithm implementation

streams of encryption.
- Thread locking was changed, in order to allow multiple encryption, and avoid
dead locks.

- encrypt() function crypt.c was renamed to __encrypt() in order to compile
in some systems.
- version number is included in the modules.
- mcrypt_list_algorithms(), mcrypt_list_modes() and mcrypt_list_keygen() now
check if the file is an mcrypt module (has the _mcrypt_xxx_version function).
November 28th, 1999:
- MARS was added (as a separate module)
November 26th, 1999:
- mcrypt_perror(int) function was added. It prints the text of an mcrypt
error code.
- Versioning has been changed. The release is no longer included in the library
name.
- Documentation was updated.
November 25th, 1999:
- crypt() and setkey() functions for enigma, were renamed to __crypt() and
__setkey() to keep some libcs happy.
- Corrected typo mistakes in twofish.c.
- Patched wake.c to work in bigendian machines.
- IDEA, RC4, RC6 which were non-free now are in a separate distribution.
November 24th, 1999:

access TWOFISH algorithm with 256 bit key, but TWOFISH with keylength of
32 bytes (==256 bits). This is more flexible than the previous API since
you can access more keys.
October 16th, 1999:
- The new API is completed.
- STREAM mode was added.
- RC4 was added.
October 15th, 1999:

- Fixes in RC2, RC6 and SAFER+ code, so they work the same way in
big-endian and little-endian machines.
- Porting of SERPENT, MARS and RIJNDAEL is not ready, they do
not work right in bigendian machines.
- Bugfixes in the tests. Tests failed if one or two algorithms failed.
September 19th, 1999
- SERPENT was added in 128,192,256 key modes.
September 15th, 1999
- MARS and RIJNDAEL were added in 128,192,256 key modes.

September 14th, 1999
- Twofish code was changed. Now it uses Dr Brian Gladman's code.
- RC2 code was changed.
June 26th, 1999
- buffer overflow fixed in lib/mcrypt.c. Pointed out by Don Sutherland <dss@yadda.net>
June 23th, 1999
- RC2 code was cleared.
- RC6 was changed according to the specification. It is RC6 32/20/32.
RC6, SAFER+, LOKI97 and CAST-256 codes are actually Dr Brian Gladman's
code a bit modified for mcrypt.
- shared library version has changed (at last!)
June 22th, 1999
- SAFER+, LOKI97 and CAST-256 Added.
June 15th, 1999 - Version 2.2
- Changes in the xTEA algorithm. Some extra parenthesis made the algorithm
differ from the specification. Pointed out by Lars Nordentoft
<lntech@post9.tele.dk>. Read the README.xtea for more information.
June 12th, 1999 - Version 2.1.1
- Changes in the documentation which was inaccurate.
June 11th, 1999 - Version 2.1
- _mcrypt_ was placed as a prefix to all internal functions so they
do not pollute namespace.
May 29th, 1999
- test suites added
- Blowfish was divided to blowfish-448, -256, -192, -128.
- CBC can now accept IV
- mlock and munlock is used before mallocing and freeing any memory,
thus if such capabilities exist the library guarrantees that no
password is written in the disk (as swap etc.)
- gen_key_md5() was added and gen_key() was renamed to gen_key_sha1()
gen_key() is still defined to be gen_keysha1().
May 26th, 1999 - Version 2.0
- Documentation was incorrect and innacurate. Corrected.
- A #define WORDS_BIGENDIAN 0 was removed from acconfig.h, this
was confusing all the library headers, and thus the library was
useless.
- nbit-ofb mode added. n is the blocksize of the algorithm. Still
experimental.
May 24th, 1999 - Version 1.93
- defined get_block_size to be mcrypt_get_block_size so php3.0.8 compiles ok
May 17th, 1999 - Version 1.9
- gen_key() changed
- libtool support (based on Sascha Schumann's patches)
