Description:

A replacement for the old unix crypt(1) command. Mcrypt uses the
following encryption (block) algorithms: BLOWFISH, DES, TripleDES,
3-WAY, SAFER-SK64, SAFER-SK128, CAST-128, RC2 TEA (extended), TWOFISH,
RC6, IDEA and GOST. The unix crypt algorithm is also included, to
allow compability with the crypt(1) command.

CBC, ECB, OFB and CFB modes of encryption are supported. A library
which allows access to the above algorithms and modes is included.
