-/* des routines for non-usa - eay 10/9/1991 eay@psych.psy.uq.oz.au
- * These routines were written for speed not size so they are bigger than
- * needed. I have removed some of the loop unrolling, this will reduce
- * code size at the expense of some speed.
- * 25/9/1991 eay - much faster _XdmcpAuthSetup (4 times faster).
- * 19/9/1991 eay - cleaned up the IP and FP code.
- * 10/9/1991 eay - first release.
- * The des routines this file has been made from can be found in
- * ftp.psy.uq.oz.au /pub/DES
- * This particular version derived from OpenBSD Revsion 1.3.
