Other cleanups.

1 nmav 1.26 Sep 8th 2001:
2 nmav 1.24 - Added option to include algorithms and modes into the library
3     (making possible a static library)
4 nmav 1.25 eg. './configure --with-included-algos="rijndael-128 twofish cbc ecb"' will add
5     rijndael, twofish with cbc and ecb into the library
6 nmav 1.26 - Added nCFB mode (experimental)
7     - Changed get_*_name() functions semantics (does not return allocated string)
8 nmav 1.24

30     - Corrected bugs in blowfish and blowfish-compat
31    
32 nmav 1.16 January 23th 2001: (version 2.4.9-beta)
33 nmav 1.15 - Due to an endianness handling problem Blowfish algorithm was not compatible
34     with other implementations. Now it has been corrected. If you want
35     to access the old algorithm used use the "blowfish-compat" module.
36 nmav 1.10 - Fixes in mcrypt_list_algorithms() for some systems. Bugs pointed out by
37     Jonathan Woolmington <jwool@ind.tansu.com.au>
38 nmav 1.14 - Fixes in stream mode.
39 nmav 1.11 - mcrypt_generic_init() no longer fails if smaller key is used. It uses
40     the most appropriate key size of the algorithm and pads with zeros.
41 nmav 1.14 - Fixes in wake algorithm (and support for IV).
42     - IV is now used in arcfour (arcfour-iv is now longer used). Speedups in Arcfour.
43 nmav 1.16 - mcrypt_generic_deinit() function added.

57 nmav 1.2 - Speedups in the blowfish algorithm
58    
59 nmav 1.1 May 12th, 2000: (version 2.4.4)

61    
62     April 3rd, 2000: (version 2.4.2)
63     - Added missing symbols.
64    
65     April 2nd, 2000: (version 2.4.1)
66     - Bugfixes
67     - Internal changes in mode modules
68     - Changes in the documentation
69    
70     March 19th, 2000: (version 2.4.0)
71     - Corrected bugs in the extra algorithms.
72     - Libmcrypt is now thread safe without need for posix thread locks.
73     - Libmcrypt is no longer compatible with 2.2 or 2.3 version.
74     - Speedups in the library.
75     - The crypt algorithm has changed. In order for it's output to be compatible
76     with the unix crypt output, the key must be generated using crypt(3).
77     This was made in order to remove the key transformation, which was
78     included in the algorithm.
79     - The crypt algorithm was renamed to enigma.
80     - Changed many function's names in order to minimize namespace polution.
81     View the manpage for more information.
82    
83     March 4th, 2000: (version 2.3.4)
84     - Improved POSIX Threads detection by Sascha Schumann
85     - Arcfour was renamed to arcfour-iv. The arcfour algorithm now does not
86     support iv (as the original algorithm does).
87     - Modes for block algorithms are not limited any more to a 256 bit block size.
88     - Mcrypt 2.2 compatibility functions were added.
89     - mcrypt_get_algo_key_size(), mcrypt_get_algo_block_size() functions
90     were added.
91    
92     February 28th, 2000: (version 2.3.3)
93     - Some dlsyms were cached causing a 50% increase in speed.
94    
95     February 27th, 2000:
96     - A slightly modified version of libmcrypt 2.2.4 was released in order
97     for mcrypt 2.5.0 to be able to compile against that series of libmcrypt.
98    
99     February 22, 2000:
100     - mcrypt_is_block_algorithm_mode(), mcrypt_is_block_mode(),
101     mcrypt_is_block_algorithm(), functions were added.
102     - Bugfixes in the mcrypt_module_self_test().
103    
104     February 8th, 2000:
105     - Keygen functionality was added to the cvs version of libmhash.
106     Libmcrypt seems to compile fine.
107    
108     January 21st, 2000:
109     - Locks were added to libltdl calls so libmcrypt is still thread safe.
110    
111     January 20th, 2000: (version 2.3.0)
112     - Tried to include libltdl. Not succesful yet. It compiles but it does
113     not work.
114     - keygen functionality was removed. It will be added to libmhash
115     http://schumann.cx/mhash
116    
117     January 13th, 2000:
118     - Changed the sha-1 algorithm implementation

120     - arcfour was added.
121    
122     December 12th, 1999:
123     - Included patches by Steve Underwood, to allow an arbitary number of
124     streams of encryption.
125     - Thread locking was changed, in order to allow multiple encryption, and avoid
126     dead locks.
127    
128     December 10th, 1999:
129     - Wake algorithm now supports IV.
130    
131     December 4th, 1999:

133    
134     December 2nd, 1999:
135     - Bug fixes in the panama and xtea algorithms.
136     - The version of the module now can be checked at run-time (check mcrypt.h)
137    
138     November 30th, 1999:
139     - Corrections in the panama algorithm, in order to work fine in big-endian
140     machines.
141    
142     November 29th, 1999:
143     - encrypt() function crypt.c was renamed to __encrypt() in order to compile
144     in some systems.
145     - version number is included in the modules.
146     - mcrypt_list_algorithms(), mcrypt_list_modes() and mcrypt_list_keygen() now
147     check if the file is an mcrypt module (has the _mcrypt_xxx_version function).
148    
149     November 28th, 1999:
150     - MARS was added (as a separate module)
151    
152     November 26th, 1999:
153     - mcrypt_perror(int) function was added. It prints the text of an mcrypt
154     error code.
155     - Versioning has been changed. The release is no longer included in the library
156     name.
157     - Documentation was updated.
158    
159     November 25th, 1999:
160     - crypt() and setkey() functions for enigma, were renamed to __crypt() and
161     __setkey() to keep some libcs happy.
162     - Corrected typo mistakes in twofish.c.
163     - Patched wake.c to work in bigendian machines.
164     - IDEA, RC4, RC6 which were non-free now are in a separate distribution.
165    
166     November 24th, 1999:
167     - sdes key generation module was corrected. Now it works fine with
168     des(1).
169    
170     November 20th, 1999:
171     - Mcrypt is now modular. Modes, algorithm, and key generation modules, can
172     be loaded dynamically.
173    
174     November 17th, 1999:
175     - PANAMA stream algorithm was added (experimental).
176     - WAKE stream algorithm was added (experimental).
177    
178     November 13th, 1999:
179     - Blowfish algorithm was changed, it is now compatible with other implementations.
180     - Accessing algorithms is now different. You do not specify TWOFISH_256, to
181     access TWOFISH algorithm with 256 bit key, but TWOFISH with keylength of
182     32 bytes (==256 bits). This is more flexible than the previous API since
183     you can access more keys.
184    
185     October 16th, 1999:
186     - The new API is completed.
187     - STREAM mode was added.
188     - RC4 was added.
189    
190     October 15th, 1999:

202     - rijndael implementation by Mike Scott was added.
203    
204     September 29th, 1999:
205     - Minor bugfixes and optimization in the library. Now it uses less memory.
206    
207     September 20th, 1999:
208     - Fixes in RC2, RC6 and SAFER+ code, so they work the same way in
209     big-endian and little-endian machines.
210     - Porting of SERPENT, MARS and RIJNDAEL is not ready, they do
211     not work right in bigendian machines.
212     - Bugfixes in the tests. Tests failed if one or two algorithms failed.
213    
214     September 19th, 1999
215     - SERPENT was added in 128,192,256 key modes.
216    
217     September 15th, 1999
218     - MARS and RIJNDAEL were added in 128,192,256 key modes.
219     - RC6 was splitted to RC6_128, RC6_192 and RC6_256 (the old RC6 is equal to RC6_256)
220     - RC2 was splitted to RC2_128, RC2_256 and RC2_1024 (the old RC2 is equal to RC2_1024)
221    
222     September 14th, 1999
223     - Twofish code was changed. Now it uses Dr Brian Gladman's code.
224     - RC2 code was changed.
225    
226     June 26th, 1999
227     - buffer overflow fixed in lib/mcrypt.c. Pointed out by Don Sutherland <dss@yadda.net>
228    
229     June 23th, 1999
230     - RC2 code was cleared.
231     - RC6 was changed according to the specification. It is RC6 32/20/32.
232     RC6, SAFER+, LOKI97 and CAST-256 codes are actually Dr Brian Gladman's
233     code a bit modified for mcrypt.
234     - shared library version has changed (at last!)
235    
236     June 22th, 1999
237     - SAFER+, LOKI97 and CAST-256 Added.
238    
239     June 15th, 1999 - Version 2.2
240     - Changes in the xTEA algorithm. Some extra parenthesis made the algorithm
241     differ from the specification. Pointed out by Lars Nordentoft
242     <lntech@post9.tele.dk>. Read the README.xtea for more information.
243    
244     June 12th, 1999 - Version 2.1.1
245     - Changes in the documentation which was inaccurate.
246    
247     June 11th, 1999 - Version 2.1
248     - _mcrypt_ was placed as a prefix to all internal functions so they
249     do not pollute namespace.
250    
251     May 29th, 1999
252     - test suites added
253     - Blowfish was divided to blowfish-448, -256, -192, -128.
254     - CBC can now accept IV
255     - mlock and munlock is used before mallocing and freeing any memory,
256     thus if such capabilities exist the library guarrantees that no
257     password is written in the disk (as swap etc.)
258     - gen_key_md5() was added and gen_key() was renamed to gen_key_sha1()
259     gen_key() is still defined to be gen_keysha1().
260    
261     May 26th, 1999 - Version 2.0
262     - Documentation was incorrect and innacurate. Corrected.
263     - A #define WORDS_BIGENDIAN 0 was removed from acconfig.h, this
264     was confusing all the library headers, and thus the library was
265     useless.
266     - nbit-ofb mode added. n is the blocksize of the algorithm. Still
267     experimental.
268    
269     May 24th, 1999 - Version 1.93
270     - defined get_block_size to be mcrypt_get_block_size so php3.0.8 compiles ok
271    
272     May 17th, 1999 - Version 1.9
273     - gen_key() changed
274     - libtool support (based on Sascha Schumann's patches)
