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