ccrypt - 1.11-2 main

ccrypt is a utility for encrypting and decrypting files and streams. It was
designed as a replacement for the standard unix crypt utility, which is
notorious for using a very weak encryption algorithm. ccrypt is based on the
Rijndael cipher, which is the U.S. government's chosen candidate for the
Advanced Encryption Standard (AES, see http://www.nist.gov/aes). This cipher is
believed to provide very strong security.
