	  Use SPARC64 crypto opcodes for AES algorithm.



	  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



	  See <http://csrc.nist.gov/encryption/aes/> for more information.



	  In addition to AES cipher algorithm support, the acceleration

	  for some popular block cipher mode is supported too, including

	  ECB and CBC.
