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.
