+          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
