Late breaking news:	Versions of uuencode and uudecode now included, which are helpful	for using this package to send/receive encrypted mail.Phil asked me to clean this up slightly and package it for distribution.I've got it running on my Symmetric 4.2bsd system, Phil reports it runs fineon a variety of systems at Bellcore.  Note that getopt is required but notprovided, as there is already a getopt package in the mod.sources archives.Bdale Garbee, N3EUA  870401	winfree!bdale aka bdale%winfree.uucp@flash.bellcore.com- - - - -This package contains a DES subroutine library based on the original publicdomain code by James Gillogly, but made faster and more flexible. Commandsusing this library have been added for testing and for encrypting anddecrypting files (compatible with the DES command under Sun UNIX), amongother things.Run make. That will compile everything and run test data (from the NBScertification suite) through it.  It runs as-is under UNIX. It will rununder MS-DOS with a few minor changes: make sure you define LITTLE_ENDIANwhen compiling des.c, and change the name of the console in getpass.c.  Ifyou have the byte order flag set wrong, you will get ENCRYPT FAIL messageswhen the descert test is run.radlogin.c is an experimental program for secure UNIX login via insecurechannels (like amateur packet radio). Make it and set it up as the loginshell for a special, password-free login (e.g., "radio"). When it starts theuser will be asked his REAL login name, which is then looked up in/etc/rkeys. (This file must be read protected since it contains DES keys).The time of day is then printed in hex as a challenge. The user must encryptit using DES and his key and type the answer back.  The user may use theprogram "descalc" to perform his local calculation. All this is very clumsy;it works, but after all it's only experimental.Phil Karn, KA9Qbellcore!karn aka karn@flash.bellcore.com- - - - -Subject: Re:  rkeys filerkeys:karn 0123456789abcdefuid  des_key_in_hex- - - - -
