Advanced Encryption Standard
Rijndael

   <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.
