In article <1990Dec27.004813.25021@news.cs.indiana.edu> you write: >If the DES enryption algorythm is PD, please send me a copy The DES algorithm is most definitely PD. It was published in the Federal Register, Vol 40 No 149, August 1 1975, pages 32395-32414. If you're not familiar with the Federal Register, it's an enormous and generally incredibly boring journal put out by the government in which is published all of the government's public notices. It is not copyrighted; I have a xerox of the DES on my desk. Run down to the library and make your own copy. It is also available as FIPS 46, published by NIST, and ANSI X3.92-1981. FIPS are distributed by NTIS. ANSI distributes their own stuff, you can call them in New York to get their price. Neither is free. I'm not aware of any on-line version of DES. It'd be a pain to type in, as it contains lots of subscripts, tables of numbers, and line drawings. Perhaps some generous soul can come up with a pic+troff or postscript version. DES specifies an algorithm that takes a 64 bit plain text and a 56 bit key to produce a 64 bit encrypted text, and vice-versa. A related document is FIPS 81 or ANSI X3.106-1983 which defines ways to use DES to encrypt longer messages. Regards, John Levine, johnl@iecc.cambridge.ma.us, {spdcc|ima|world}!iecc!johnl

Someone in Australia posted a version of DES to the net some time back. There was also a version from Phil Karn (KA9Q fame). Unfortunately I don't think anyone in the US can safely post that code because of export restrictions (which so far as I know still apply to library routines which aren't strictly for user authentication purposes ...) -- John F.

Folks your in luck. Check out the November 1990 issue of Dr. Dobb's. Al Stevens discusses the DES alogrithm and provides his own version of it. It is available from Comp-U-Serv if you don't want to type the source in your self. Please note that I haven't tried it yet. If someone does try it and it works could they please inform me.

Silly (and perhaps a bit off the subject) question time: I) Does this mean that Dr. Dobb's is now an "export restricted" item, and thus can not be mailed to any non-US subscribers? II) Does this now mean that Comp-U-Serv must restrict non-US subscriber access?

Due to some very intelligent decisions our IP routing to *.nl is via the US, so I am interested in the legal aspects of FTPing DES from Utrecht. As I understand the current situation I could FTP it if IP routing were via InterEUNet, but it would violate US export regulations if I use our default routing.

The reason for export controls on software implementations of DES have always mystified me. Here are two observations that fuel my confusion. FIPS PUB 46 states: "Software implementations in general purpose computers are not in compliance with this standard." (reference FIPS PUB 46, 15 January 1977, "Data Encryption Standard," page 2, paragraph "Hardware Implementation") How could export controls apply to something that does not comply with the standard? Assuming that software implementations of DES are subject to export controls, why would the National Institute of Standards and Technology publish a software implementation of the DES? Appendix D of FIPS PUB 112 contains a FORTRAN program for passphrase transformation and password encryption. A software implementation of DES is provided in the FORTRAN program (reference FIPS PUB 112, 30 May 1985, "Password Usage," Appendix D). FIPS PUB 112 is available from the National Technical Information Service, U.S. Department of Commerce, Springfield, VA 22161. The price of FIPS PUB 112 was $15.95 in 1989. Major credit cards accepted. mike
