Branch: MAIN
Changes since 1.3: +3 -3 lines
updates in the -ldl option. Bugfixes.

1 nmav 1.4 September 18th 2000: (version 2.4.5)
2     - Updates in the documentation
3     - Libmcrypt can now be used without libltdl (in systems where libdl is present)
4 nmav 1.3 - Added the mcrypt_enc_set_state() function.
5 nmav 1.2 - Speedups in the blowfish algorithm
6    
7 nmav 1.1 May 12th, 2000: (version 2.4.4)
8     - Added Panama algorithm
9    
10     April 3rd, 2000: (version 2.4.2)
11     - Added missing symbols.
12    
13     April 2nd, 2000: (version 2.4.1)
14     - Bugfixes
15     - Internal changes in mode modules
16     - Changes in the documentation
17    
18     March 19th, 2000: (version 2.4.0)
19     - Corrected bugs in the extra algorithms.
20     - Libmcrypt is now thread safe without need for posix thread locks.
21     - Libmcrypt is no longer compatible with 2.2 or 2.3 version.
22     - Speedups in the library.
23     - The crypt algorithm has changed. In order for it's output to be compatible
24     with the unix crypt output, the key must be generated using crypt(3).
25     This was made in order to remove the key transformation, which was
26     included in the algorithm.
27     - The crypt algorithm was renamed to enigma.
28     - Changed many function's names in order to minimize namespace polution.
29     View the manpage for more information.
30    
31     March 4th, 2000: (version 2.3.4)
32     - Improved POSIX Threads detection by Sascha Schumann
33     - Arcfour was renamed to arcfour-iv. The arcfour algorithm now does not
34     support iv (as the original algorithm does).
35     - Modes for block algorithms are not limited any more to a 256 bit block size.
36     - Mcrypt 2.2 compatibility functions were added.
37     - mcrypt_get_algo_key_size(), mcrypt_get_algo_block_size() functions
38     were added.
39    
40     February 28th, 2000: (version 2.3.3)
41     - Some dlsyms were cached causing a 50% increase in speed.
42    
43     February 27th, 2000:
44     - A slightly modified version of libmcrypt 2.2.4 was released in order
45     for mcrypt 2.5.0 to be able to compile against that series of libmcrypt.
46    
47     February 22, 2000:
48     - mcrypt_is_block_algorithm_mode(), mcrypt_is_block_mode(),
49     mcrypt_is_block_algorithm(), functions were added.
50     - Bugfixes in the mcrypt_module_self_test().
51    
52     February 8th, 2000:
53     - Keygen functionality was added to the cvs version of libmhash.
54     Libmcrypt seems to compile fine.
55    
56     January 21st, 2000:
57     - Locks were added to libltdl calls so libmcrypt is still thread safe.
58    
59     January 20th, 2000: (version 2.3.0)
60     - Tried to include libltdl. Not succesful yet. It compiles but it does
61     not work.
62     - keygen functionality was removed. It will be added to libmhash
63     http://schumann.cx/mhash
64    
65     January 13th, 2000:
66     - Changed the sha-1 algorithm implementation
67     - mcrypt_get_iv_size now calls the specified mode, not the algorithm
68     - arcfour was added.
69    
70     December 12th, 1999:
71     - Included patches by Steve Underwood, to allow an arbitary number of
72     streams of encryption.
73     - Thread locking was changed, in order to allow multiple encryption, and avoid
74     dead locks.
75    
76     December 10th, 1999:
77     - Wake algorithm now supports IV.
78    
79     December 4th, 1999:
80     - Changes in modules/modes in order to be thread-safe.
81    
82     December 2nd, 1999:
83     - Bug fixes in the panama and xtea algorithms.
84     - The version of the module now can be checked at run-time (check mcrypt.h)
85    
86     November 30th, 1999:
87     - Corrections in the panama algorithm, in order to work fine in big-endian
88     machines.
89    
90     November 29th, 1999:
91     - encrypt() function crypt.c was renamed to __encrypt() in order to compile
92     in some systems.
93     - version number is included in the modules.
94     - mcrypt_list_algorithms(), mcrypt_list_modes() and mcrypt_list_keygen() now
95     check if the file is an mcrypt module (has the _mcrypt_xxx_version function).
96    
97     November 28th, 1999:
98     - MARS was added (as a separate module)
99    
100     November 26th, 1999:
101     - mcrypt_perror(int) function was added. It prints the text of an mcrypt
102     error code.
103     - Versioning has been changed. The release is no longer included in the library
104     name.
105     - Documentation was updated.
106    
107     November 25th, 1999:
108     - crypt() and setkey() functions for enigma, were renamed to __crypt() and
109     __setkey() to keep some libcs happy.
110     - Corrected typo mistakes in twofish.c.
111     - Patched wake.c to work in bigendian machines.
112     - IDEA, RC4, RC6 which were non-free now are in a separate distribution.
113    
114     November 24th, 1999:
115     - sdes key generation module was corrected. Now it works fine with
116     des(1).
117    
118     November 20th, 1999:
119     - Mcrypt is now modular. Modes, algorithm, and key generation modules, can
120     be loaded dynamically.
121    
122     November 17th, 1999:
123     - PANAMA stream algorithm was added (experimental).
124     - WAKE stream algorithm was added (experimental).
125    
126     November 13th, 1999:
127     - Blowfish algorithm was changed, it is now compatible with other implementations.
128     - Accessing algorithms is now different. You do not specify TWOFISH_256, to
129     access TWOFISH algorithm with 256 bit key, but TWOFISH with keylength of
130     32 bytes (==256 bits). This is more flexible than the previous API since
131     you can access more keys.
132    
133     October 16th, 1999:
134     - The new API is completed.
135     - STREAM mode was added.
136     - RC4 was added.
137    
138     October 15th, 1999:
139     - libmcrypt is maintained using CVS.
140     - Major changes in the internal of the library. Much cleaner code.
141    
142     October 14th, 1999:
143     - Serpent was added.
144    
145     October 10th, 1999:
146     - Bugfix in sha1.
147    
148     October 4th, 1999:
149     - Bugfixes in rc2 and rc6.
150     - rijndael implementation by Mike Scott was added.
151    
152     September 29th, 1999:
153     - Minor bugfixes and optimization in the library. Now it uses less memory.
154    
155     September 20th, 1999:
156     - Fixes in RC2, RC6 and SAFER+ code, so they work the same way in
157     big-endian and little-endian machines.
158     - Porting of SERPENT, MARS and RIJNDAEL is not ready, they do
159     not work right in bigendian machines.
160     - Bugfixes in the tests. Tests failed if one or two algorithms failed.
161    
162     September 19th, 1999
163     - SERPENT was added in 128,192,256 key modes.
164    
165     September 15th, 1999
166     - MARS and RIJNDAEL were added in 128,192,256 key modes.
167     - RC6 was splitted to RC6_128, RC6_192 and RC6_256 (the old RC6 is equal to RC6_256)
168     - RC2 was splitted to RC2_128, RC2_256 and RC2_1024 (the old RC2 is equal to RC2_1024)
169    
170     September 14th, 1999
171     - Twofish code was changed. Now it uses Dr Brian Gladman's code.
172     - RC2 code was changed.
173    
174     June 26th, 1999
175     - buffer overflow fixed in lib/mcrypt.c. Pointed out by Don Sutherland <dss@yadda.net>
176    
177     June 23th, 1999
178     - RC2 code was cleared.
179     - RC6 was changed according to the specification. It is RC6 32/20/32.
180     RC6, SAFER+, LOKI97 and CAST-256 codes are actually Dr Brian Gladman's
181     code a bit modified for mcrypt.
182     - shared library version has changed (at last!)
183    
184     June 22th, 1999
185     - SAFER+, LOKI97 and CAST-256 Added.
186    
187     June 15th, 1999 - Version 2.2
188     - Changes in the xTEA algorithm. Some extra parenthesis made the algorithm
189     differ from the specification. Pointed out by Lars Nordentoft
190     <lntech@post9.tele.dk>. Read the README.xtea for more information.
191    
192     June 12th, 1999 - Version 2.1.1
193     - Changes in the documentation which was inaccurate.
194    
195     June 11th, 1999 - Version 2.1
196     - _mcrypt_ was placed as a prefix to all internal functions so they
197     do not pollute namespace.
198    
199     May 29th, 1999
200     - test suites added
201     - Blowfish was divided to blowfish-448, -256, -192, -128.
202     - CBC can now accept IV
203     - mlock and munlock is used before mallocing and freeing any memory,
204     thus if such capabilities exist the library guarrantees that no
205     password is written in the disk (as swap etc.)
206     - gen_key_md5() was added and gen_key() was renamed to gen_key_sha1()
207     gen_key() is still defined to be gen_keysha1().
208    
209     May 26th, 1999 - Version 2.0
210     - Documentation was incorrect and innacurate. Corrected.
211     - A #define WORDS_BIGENDIAN 0 was removed from acconfig.h, this
212     was confusing all the library headers, and thus the library was
213     useless.
214     - nbit-ofb mode added. n is the blocksize of the algorithm. Still
215     experimental.
216    
217     May 24th, 1999 - Version 1.93
218     - defined get_block_size to be mcrypt_get_block_size so php3.0.8 compiles ok
219    
220     May 17th, 1999 - Version 1.9
221     - gen_key() changed
222     - libtool support (based on Sascha Schumann's patches)
