mcrypt

mcrypt is a program for encrypting files or streams. It is intended to be a replacement for the old UNIX crypt. It uses well-known and well-tested algorithms like DES, BLOWFISH, TWOFISH, ARCFOUR, CAST-128, and more in several modes (CBC, CFB, etc.). It also has a compatibility mode with the old UNIX crypt and Solaris des.

Some of the algorithms that mcrypt may use (like RC6 and IDEA) are not free in all countries. These algorithms are provided as extension modules to libmcrypt (the library which implements all the algorithms and modes found in mcrypt). Users should contact the companies listed in docs/README.nonfree, if you live in a country where is illegal to use them.
