I did not follow the entire dicussion and do not know what has been mentioned about the patent. I have several questions about the patent. Any help will be appreciated. 1. Who now holds the patent of the RSA cryptosystem? 2. When was the patent granted? 3. Was the patent holder involved in the original developement of the cryptosystem? If not, do the original developers of the crypto- system now hold any right to the cryptosystem? 4. On what ground was the patent granted? What aspects of the crypto- system and its application are covered by the patent? 5. What are the implications of the patent on private/commercial uses of the cryptosystem?

Lines: 26 The RFCs you want are RFC 1113 (PEM Encryption and Authentication), RFC 1114 (Certificate-Based Key Management) and 1115 (Algorithms, Modes, and Identifiers). RSA will be selling a PEM toolkit, not a complete package, and I can't imagine they will be releasing source code. Trusted Information Systems in Glenwood, MD is building a reference implementation whose source code (apparently including RSA) will be available on the Internet. New drafts of the PEM RFCs were issued over the past few months, and PEM was discussed at the IAB (IETF?) meeting a few weeks ago. There should be one more final version of the RFCs coming out soon. Most of the issues concern key management and certificates; RFCs 1113 and 1115 are fairly stable, as is *most* of RFC 1114. Other useful draft RFCs are around for the digest algorithms (MD2, MD4, MD5) and for notarization/co-certification services. The drafts are available from the usual places via FTP (I have no idea where since I have to use UUCP via uunet). There was a brief flurry of news concerning PGP in this newsgroup a month or so ago. The last I heard RSA had said they would work out some kind of licensing agreement for it, but that was right after PGP was pulled off the net. Rich Ankney
