+## Constant-time SSSE3 AES core implementation.
+## version 0.1

+# September 2011.
+#
+# Interface to OpenSSL as "almost" drop-in replacement for
+# aes-x86_64.pl. "Almost" refers to the fact that AES_cbc_encrypt
+# doesn't handle partial vectors (doesn't have to if called from
+# EVP only). "Drop-in" implies that this module doesn't share key
+# schedule structure with the original nor does it make assumption
+# about its alignment...
+#
+# Performance summary. aes-x86_64.pl column lists large-block CBC
+# encrypt/decrypt/with-hyper-threading-off(*) results in cycles per
+# byte processed with 128-bit key, and vpaes-x86_64.pl column -
+# [also large-block CBC] encrypt/decrypt.
+#
+# aes-x86_64.pl vpaes-x86_64.pl
+#
+# Core 2(**) 30.5/43.7/14.3 21.8/25.7(***)
+# Nehalem 30.5/42.2/14.6 9.8/11.8
+# Atom 63.9/79.0/32.1 64.0/84.8(***)
+#
+# (*) "Hyper-threading" in the context refers rather to cache shared
+# among multiple cores, than to specifically Intel HTT. As vast
+# majority of contemporary cores share cache, slower code path
+# is common place. In other words "with-hyper-threading-off"
+# results are presented mostly for reference purposes.
+#
+# (**) "Core 2" refers to initial 65nm design, a.k.a. Conroe.
+#
+# (***) Less impressive improvement on Core 2 and Atom is due to slow
+# pshufb, yet it's respectable +40%/78% improvement on Core 2
+# (as implied, over "hyper-threading-safe" code path).
