Hello ,

MCrypt is a replacement for the popular Unix crypt command.

Mcrypt provides the same functionality but uses several modern algorithms such as AES. Libmcrypt, Mcrypt’s companion, is a library of code which contains the actual encryption functions and provides an easy method for use.

It implements numerous cryptographic algorithms, mostly block ciphers and stream ciphers, some of which falls under export restrictions in the United States. Algorithms include DES, Blowfish, ARCFOUR, Enigma, GOST, LOKI97, RC2, Serpent, Threeway, Twofish, WAKE, and XTEA.
