 133           This is the s390 hardware accelerated implementation of the
 134           AES cipher algorithms (FIPS-197). AES uses the Rijndael
 135           algorithm.
 136
 137           Rijndael appears to be consistently a very good performer in
 138           both hardware and software across a wide range of computing
 139           environments regardless of its use in feedback or non-feedback
 140           modes. Its key setup time is excellent, and its key agility is
 141           good. Rijndael's very low memory requirements make it very well
 142           suited for restricted-space environments, in which it also
 143           demonstrates excellent performance. Rijndael's operations are
 144           among the easiest to defend against power and timing attacks.
