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