 819           AES cipher algorithms (FIPS-197). AES uses the Rijndael
 820           algorithm.
 821
 822           Rijndael appears to be consistently a very good performer in
 823           both hardware and software across a wide range of computing
 824           environments regardless of its use in feedback or non-feedback
 825           modes. Its key setup time is excellent, and its key agility is
 826           good. Rijndael's very low memory requirements make it very well
 827           suited for restricted-space environments, in which it also
 828           demonstrates excellent performance. Rijndael's operations are
 829           among the easiest to defend against power and timing attacks.
 830
 831           The AES specifies three key sizes: 128, 192 and 256 bits

 846           and for XTS mode encryption, CBC and XTS mode decryption speedup is
 847           around 25%. (CBC encryption speed is not affected by this driver.)
