# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
# project. The module is, however, dual licensed under OpenSSL and
# CRYPTOGAMS licenses depending on where you obtain it. For further
# details see http://www.openssl.org/~appro/cryptogams/.
# ====================================================================
# Needs more work: key setup, page boundaries, CBC routine...
#
# ppc_AES_[en|de]crypt perform at 18 cycles per byte processed with
# 128-bit key, which is ~40% better than 64-bit code generated by gcc
# 4.0. But these are not the ones currently used! Their "compact"
# counterparts are, for security reason. ppc_AES_encrypt_compact runs
# at 1/2 of ppc_AES_encrypt speed, while ppc_AES_decrypt_compact -
# at 1/3 of ppc_AES_decrypt.
