Modes of operation

Different algorithms are used to encipher or decipher DES data or keys and AES data or keys.

To encipher or decipher DES data or keys, CCA uses the U.S. National Institute of Standards and Technology (NIST) Data Encryption Standard (DES) algorithm, with single-length, double-length, or triple-length keys.

To encipher or decipher AES data or keys, CCA uses the U.S. National Institute of Standards and Technology (NIST) Advanced Encryption Standard (AES) algorithm, with 16-byte, 24-byte or 32-byte keys.

The Encipher and Decipher verbs operate in DES CBC (Cipher Block Chaining) mode.
