 817           algorithm.
 818
 819           Rijndael appears to be consistently a very good performer in
 820           both hardware and software across a wide range of computing
 821           environments regardless of its use in feedback or non-feedback
 822           modes. Its key setup time is excellent, and its key agility is
 823           good. Rijndael's very low memory requirements make it very well
 824           suited for restricted-space environments, in which it also
 825           demonstrates excellent performance. Rijndael's operations are
 826           among the easiest to defend against power and timing attacks.
 827
 828           The AES specifies three key sizes: 128, 192 and 256 bits

 830           See <http://csrc.nist.gov/encryption/aes/> for more information.
