-#!/usr/bin/env perl
-#
-# ====================================================================
-# Written by Andy Polyakov <appro@openssl.org> 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/.
-# ====================================================================
-#
-# April 2010
-#
-# The module implements "4-bit" GCM GHASH function and underlying
-# single multiplication operation in GF(2^128). "4-bit" means that it
-# uses 256 bytes per-key table [+128 bytes shared table]. On PA-7100LC
-# it processes one byte in 19.6 cycles, which is more than twice as
-# fast as code generated by gcc 3.2. PA-RISC 2.0 loop is scheduled for
-# 8 cycles, but measured performance on PA-8600 system is ~9 cycles per
-# processed byte. This is ~2.2x faster than 64-bit code generated by
-# vendor compiler (which used to be very hard to beat:-).
-#
-# Special thanks to polarhome.com for providing HP-UX account.
