222 This is the s390 hardware accelerated implementation of the
223 AES cipher algorithms (FIPS-197). AES uses the Rijndael
224 algorithm.
225
226 Rijndael appears to be consistently a very good performer in
227 both hardware and software across a wide range of computing
228 environments regardless of its use in feedback or non-feedback
229 modes. Its key setup time is excellent, and its key agility is
230 good. Rijndael's very low memory requirements make it very well
231 suited for restricted-space environments, in which it also
232 demonstrates excellent performance. Rijndael's operations are
233 among the easiest to defend against power and timing attacks.
234
235 On s390 the System z9-109 currently only supports the key size
236 of 128 bit.
