March 08 2003: (version 2.5.7)
|
||||
- The mcrypt_symb.c file is generated only when needed. This should
|
||||
fix some problems in systems with incompatible sed.
|
||||
|
||||
January 19 2003: (version 2.5.6)
|
||||
- Fixes in win32 detection and DLL building.
|
||||
- Fixes for solaris (a symbol was not exported)
|
||||
- Corrected bug which made algorithm symbols to be inserted
|
||||
twice in symbol table.

|
||||
by Ilia A. <ilia@prohost.org>
|
||||
- Made the default behaviour to include all algorithms into
|
||||
the main library, instead of using dynamic modules. Dynamic
|
||||
loading is disabled by default. The --enable-dynamic-loading flag
|
||||
can be used in the configure script, to get the old behaviour.
|
||||
- Some fixes in ECB mode.

|
||||
- Corrected bugs in blowfish and blowfish-compat
|
||||
|
||||
January 23th 2001: (version 2.4.9-beta)
|
||||
- Due to an endianness handling problem Blowfish algorithm was not compatible
|
||||
with other implementations. Now it has been corrected. If you want
|
||||
to access the old algorithm used use the "blowfish-compat" module.
|
||||
- Fixes in mcrypt_list_algorithms() for some systems. Bugs pointed out by
|
||||
Jonathan Woolmington <jwool@ind.tansu.com.au>
|
||||
- Fixes in stream mode.
|

- mcrypt_generic_init() no longer fails if smaller key is used. It uses
|
||||
the most appropriate key size of the algorithm and pads with zeros.
|
||||
- Fixes in wake algorithm (and support for IV).
|
||||
- IV is now used in arcfour (arcfour-iv is now longer used). Speedups in Arcfour.
|
||||
- mcrypt_generic_deinit() function added.
|
||||
|
||||
January 1st 2001: (version 2.4.8)
|
||||
- Corrected bug in rijndael-256 (reported by: Sami Farin <sfarin@ratol.fi>)
|
||||
This makes the algorithm incompatible with previous versions.

|
||||
- Compiles under win32 using cygwin (with -mno-cygwin)

March 19th, 2000: (version 2.4.0)
|
||||
- Corrected bugs in the extra algorithms.
|
||||
- Libmcrypt is now thread safe without need for posix thread locks.
|
||||
- Libmcrypt is no longer compatible with 2.2 or 2.3 version.
|
||||
- Speedups in the library.
|
||||
- The crypt algorithm has changed. In order for it's output to be compatible
|
||||
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.
|
||||

|
||||
- Some dlsyms were cached causing a 50% increase in speed.
|
||||
|
||||
February 27th, 2000:
|
||||
- A slightly modified version of libmcrypt 2.2.4 was released in order

|
||||
- Keygen functionality was added to the cvs version of libmhash.
|
||||
Libmcrypt seems to compile fine.
|
||||
|
||||
January 21st, 2000:
|
||||
- Locks were added to libltdl calls so libmcrypt is still thread safe.
|
||||
|
||||
January 20th, 2000: (version 2.3.0)
|
||||
- Tried to include libltdl. Not succesful yet. It compiles but it does
|

|
||||
http://schumann.cx/mhash

streams of encryption.
|

|
||||
machines.
|
||||
|
||||
November 29th, 1999:
|
||||
- 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:
|
||||

|
||||
des(1).
|
||||
|
||||
November 20th, 1999:
|
||||
- Mcrypt is now modular. Modes, algorithm, and key generation modules, can
|
||||
be loaded dynamically.
|
||||
|
||||
November 17th, 1999:
|
||||
- PANAMA stream algorithm was added (experimental).

|
||||
|
||||
November 13th, 1999:
|
||||
- Blowfish algorithm was changed, it is now compatible with other implementations.
|
||||
- Accessing algorithms is now different. You do not specify TWOFISH_256, to
|
||||
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.
|
||||

|
||||
|
||||
September 20th, 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
|
||||

|
||||
|
||||
September 15th, 1999
|
||||
- MARS and RIJNDAEL were added in 128,192,256 key modes.
|
||||
- RC6 was splitted to RC6_128, RC6_192 and RC6_256 (the old RC6 is equal to RC6_256)
|
||||
- RC2 was splitted to RC2_128, RC2_256 and RC2_1024 (the old RC2 is equal to RC2_1024)
|
||||
|
||||
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)
