mcrypt binary package in Ubuntu Trusty amd64

 mcrypt is a crypting program, intended to be replacement for the old
 unix crypt(1). But it can do a lot more, since with its libmcrypt
 library it can encrypt and decrypt with the following alogirhtms:
 BLOWFISH, TWOFISH, DES, TripleDES, 3-WAY, SAFER-sk64, SAFER-sk128,
 SAFER+, OKI97, GOST, RC2, RC6, MARS, IDEA, RIJNDAEL-128,
 RIJNDAEL-192, SERPENT, RIJNDAEL-256, CAST-128 (known as CAST5),
 CAST-256, ARCFOUR, ENIGMA, PANAMA, XTEA and WAKE.
 .
 Please note that this package is buggy and unmaintained by
 the upstream authors. If you can, please look for other
 implementations (openssl, gnutls, gnupg).
