Triple DES

Product cipher that, like DES, operates on 64bit data blocks. There are several forms, each of which uses the DES cipher 3 times. Some forms use two 56bit keys, some use three. (. See NIST FIPS 463 and CNSSAM IA/0204)

Advanced Encryption StandardAdvanced Encryption Standard, a new encryption standard, whose development and selection was sponsored by NIST, that will support key lengths of 128, 192, and 256 bits. FIPS approved cryptographic algorithm that is a symmetric block cipher using cryptographic key sizes of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. The encryption standard selected in October 2000 by the National Institute of Standards and Technology (NIST) that is based on the Rijndael cipher.
