Advanced Encryption Standard

cryptography, algorithm (AES) The NIST's replacement for

the Data Encryption Standard (DES). The Rijndael

/rayn-dahl/ symmetric block cipher, designed by Joan Daemen

and Vincent Rijmen, was chosen by a NIST contest to be AES.

AES is Federal Information Processing Standard FIPS-197.

AES currently supports 128, 192 and 256-bit keys and

encryption blocks, but may be extended in multiples of 32

bits.
