* This file contains the core of a bitslice DES implementation for x86-64/SSE2.

* Copyright (c) 2000-2001,2005,2006,2008,2011,2012,2015,2019 by Solar Designer
* Redistribution and use in source and binary forms, with or without

*
* Gate counts per S-box: 49 44 46 33 48 46 46 41
* Average: 44.125
*
* The Boolean expressions corresponding to DES S-boxes have been generated
* by Roman Rusakov <roman_rus at openwall.com> for use in Openwall's
* John the Ripper password cracker: http://www.openwall.com/john/
* Being mathematical formulas, they are not copyrighted and are free for reuse
* by anyone.
*
* The x86-64/SSE2 code for the S-boxes was generated by Solar Designer using a
* Perl script. The script performed various optimizations, including the
* x86-64 specific optimization of preferring registers 0-7 over 8-15 to reduce
* the number of instruction prefixes (and thus code size). The instruction
* scheduling has been tuned for Core 2.
*
* The effort has been sponsored by Rapid7: http://www.rapid7.com
