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.
