Distribution: sci Date: Tue, 3 Mar 1992 18:55:30 GMT Lines: 397 RSAREF(TM): A Cryptographic Toolkit for Privacy-Enhanced Mail RSA Laboratories (A division of RSA Data Security, Inc.) March 3, 1992 This document copyright (C) 1992 RSA Laboratories, a division of RSA Data Security, Inc. License is granted to reproduce, copy, post, or distribute in any manner, provided this document is kept intact and no modifications, deletions, or additions are made. WHAT IS IT? RSAREF is a cryptographic toolkit designed to facilitate rapid deployment of Internet Privacy-Enhanced Mail (PEM) implementations. RSAREF represents the fruits of RSA Data Security's commitment to the U.S. Department of Defense's Advanced Research Projects Agency (DARPA) to provide free cryptographic source code in support of a PEM standard. RSA Laboratories offers RSAREF in expectation of PEM's forthcoming publication as an Internet standard. Part of RSA's commitment to DARPA was to authorize Trusted Information Systems of Glenwood, MD, to distribute a full PEM implementation based on RSAREF. That implementation will be available this spring. RSAREF supports the following PEM-specified algorithms: o RSA encryption and key generation, as defined by RSA Laboratories' Public-Key Cryptography Standards (PKCS) o MD2 and MD5 message digests o DES (Data Encryption Standard) in cipher-block chaining mode RSAREF is written in the C programming language as a library that can be called from an application program. A simple PEM implementation can be built directly on top of RSAREF, together with message parsing and formatting routines and certificate-management routines. RSAREF is distributed with a demonstration program that shows how one might build such an implementation. The name "RSAREF" means "RSA reference." RSA Laboratories intends RSAREF to serve as a portable, educational, reference implementation of cryptography. WHAT YOU CAN (AND CANNOT) DO WITH RSAREF The license at the end of this note gives legal terms and conditions. Here's the layman's interpretation, for information only and with no legal weight: 1. You can use RSAREF in personal, noncommercial applications, as long as you follow the interface described in the RSAREF documentation. You can't use RSAREF in any commercial (moneymaking) manner of any type, nor can you use it to provide services of any kind to any other party. For information on commercial licenses of RSAREF-compatible products, please contact RSA Data Security. 2. You can distribute programs that interface to RSAREF, but you can't distribute RSAREF itself. Everyone must obtain his or her own copy of RSAREF. (However, free licenses to redistribute RSAREF are available. For information, please send electronic mail to <rsaref-adm...@rsa.com>.) 3. You can modify RSAREF as required to port it to other operating systems and compilers, as long as you give a copy of the results to RSA Laboratories. You can't otherwise change RSAREF. 4. You can't send RSAREF outside the United States, or give it to anyone who is not a United States citizen and doesn't have a "green card." (These are U.S. State and Commerce Department requirements, because RSA and DES are export-controlled technologies.) The restrictions on the distribution of RSAREF are the consequence of export-control law. Similar constraints are placed on those redistributing RSAREF under free license from RSA Laboratories. Without the export-control law, RSAREF would be available by anonymous FTP. HOW TO GET IT To obtain RSAREF, read the license at the end of the note and return a copy of the "acknowledgement and acceptance" paragraph by electronic mail to <rsaref-adm...@rsa.com>. RSAREF is distributed by electronic mail in a UNIX(TM) "uuencoded" TAR format. When you receive it, store the contents of the message in a file, and run your operating system's "uudecode" and TAR programs. For example, suppose you store the contents of your message in the file 'contents'. You would run the commands: uudecode contents # produces rsaref.tar tar xvf rsaref.tar RSAREF includes about 60 files organized into the following subdirectories: doc documentation on RSAREF and RDEMO install makefiles for various operating systems rdemo RDEMO demonstration program source RSAREF source code and include files test test scripts for RDEMO USERS' GROUP RSA Laboratories maintains the electronic-mail users' group <rsaref...@rsa.com> for discussion of RSAREF applications, bug fixes, etc. To join the user's group, send electronic mail to <rsaref-use...@rsa.com>. REGISTRATION RSAREF users who register with RSA Laboratories are entitled to free RSAREF upgrades and bug fixes as soon as they become available and a 50% discount on selected RSA Data Security products. To register, send your name, address, and telephone number to <rsaref-re...@rsa.com>. INNOVATION PRIZES RSA Laboratories will award cash prizes for the best applications built on RSAREF. If you'd like to submit an application, or want to be on the review panel, please send electronic mail to <rsaref-adm...@rsa.com>. PUBLIC-KEY CERTIFICATION RSA Data Security offers public-key certification services conforming to forthcoming PEM standards. For more information, please send electronic mail to <pem-...@rsa.com>.

I'm not a lawyer and I don't even play one on TV, but I have a couple observations to make. I don't think PEM is going to take off if its users have to either pay RSA royalties or abide by the export-control restrictions on RSAREF. Speaking of which, point 4 of the legal summary looks obsolete and incorrect to me. As I recall, the US Dept. of Commerce now permits export of cryptographic technology to at least Canada without a big fuss (i.e. Canada is considered equivalent to the US for purposes of crypto export). Given the recent snuggling up to what used to the USSR, I wouldn't be shocked if this stuff can even to shipped there with only a little trouble; the Big Red Bogeyman is no longer under the bed. And finally a brief flame: bloody software patents and silly goddamned government regulations are continuing to bugger up any possibility of progress in the actual use of non-trivial encryption technology. This has got to stop if we are ever going to get any serious benefit from these technologies. Various governments are going to have to bite the bullet and admit the possibility that they can't know everything and that people are genuinely entitled to real, live privacy from blasted government interference. Not that I expect that from a government that thinks that a War On The Constitution (er, Drugs) is a rational concept, let alone a winnable war.

RSAREF does *not* require the keys that you use be registered in any particular key registry. In fact RSAREF does not even require certificates. It is designed to make writing a PEM application easy, it does some of the things that you need to do, but it does not limit what you do. There is no "built in" root key. As for requiring people to reveal their private key in order to get registered (if registration was required, which it isn't), NO ONE IN THE PEM IMPLEMENTORS AND DESIGNERS COMMUNITY EVER *EVER* ENVISIONED PEOPLE NEEDING TO DO THIS. I have written a PEM implementation here at MIT. In my implementation each user generates her own public/private key pair. The private key is stored on disk encrypted in a DES key which is derived from a password that the user is prompted for. Only the public key needs be revealed to the certifying authority in order to get it registered. Of course one of the problems with my implementation (if you wish to call this a problem) is that if someone forgets their password, they are hosed and can no longer decrypt any messages sent to them encrypted in the corresponding public key. Please people, verify your facts before flaming. RSAREF is available *now* get a copy and examine it rather then speculate how it works (not to mention being paranoid about it). -Jeff

At the risk of offending someone at RSA who really does mean well by this campain, I would say that this is no different than DEC giving computers to universities since the late 70's. DEC's only interest was in making sure that everyone who graduated from college with a CS or EE degree was a PDP-11 expert. Why ? So he/she would insist that their employers use DEC computers. Marketing, pure and simple. It seems to me that if RSA really had *our* interests in mind then there would be no restrictions on commercial use. Afterall, to be viewed as a standard, it must be used universally. This will only happen if it can be painlessly included in commercial applications. What RSA is really trying to do (IMHO) is seed the market with free copies of their code, hoping that its use will become widespread. Then, as commercial developers realize that they will need to include it in their products for compatibility, RSA will have a lock on the market. If these guys were so magnanimous they would be giving it away with no strings attached. They aren't. -Brian

With IBM, Apple, DEC, Sun, Novell, Microsoft, Unisys, WordPerfect, Lotus, Motorola, etc. already licensed to incorporate RSA into systems and applications at no measurable cost to the user ("painlessly"), I don't think you can make the argument that RSA Labs released RSAREF to "lock up the market." As stated in the RSAREF announcement, RSAREF is the fulfillment of a commitment to DARPA to provide free software in support of an Internet PEM standard. I believe it does that.
