DECRYPT is a DCL command that decrypts files previously encrypted with the ENCRYPT command. DES is the default algorithm unless otherwise specified with the /KEY_ALGORITHM qualifier. The key specified must match the algorithm (DES or AES), and the same key is used to decrypt as was used to encrypt; a symmetric key algorithm.
