- * Support for Intel AES-NI intruction set
- *   Author: Huang Ying <[email protected]>
- *
- * Intel AES-NI is a new set of Single Instruction Multiple Data
- * (SIMD) instructions that are going to be introduced in the next
- * generation of Intel processor, as of 2009. These instructions
- * enable fast and secure data encryption and decryption, using the
- * Advanced Encryption Standard (AES), defined by FIPS Publication
- * number 197.  The architecture introduces six instructions that
- * offer full hardware support for AES. Four of them support high
- * performance data encryption and decryption, and the other two
- * instructions support the AES key expansion procedure.
- *
- * The white paper can be downloaded from:
- *   http://softwarecommunity.intel.com/isn/downloads/intelavx/AES-Instructions-Set_WP.pdf
- *
- * This file is based on engines/e_padlock.c
