Lines: 69 Distribution: sci Message-ID: <BURT.93Nov16145504@chirality.rsa.com> NNTP-Posting-Host: chirality.rsa.com Revised versions of the Public-Key Cryptography Standards (PKCS), the informal intervendor standards developed in 1991 by RSA Laboratories with representatives of Apple, Digital, Lotus, Microsoft, MIT, Northern Telecom, Novell and Sun, are now available via anonymous FTP to rsa.com or via electronic mail to <pk...@rsa.com>. Major improvements include the following: o PKCS #7, the cryptographic message standard, now supports certificate-revocation lists (CRLs), "certificates-only" messages, and messages encrypted with only secret-key algorithms o PKCS #10, a new standard for certification requests, is added. The standard gives compact formats for requesting key certification services such as those offered by RSA Data Security and other certification authorities. Editorial improvements include updates to the references and the addition of a revision history. PKCS #1 now gives a comparison of the MD2, MD4, MD5 message-digest algorithms; the overview addresses compatibility between PKCS and new work, including NIST's proposed Digital Signature Standard, ISO/IEC 9796, and ANSI X9.30 and .31; and the examples reflect new naming conventions. Suggestions for further improvements are welcome. Since its publication in June 1991, PKCS has become a part of several standards and products, including Internet Privacy-Enhanced Mail, the NIST/OSI Implementors' Workshop, BLOC F3 Forms Automation, Apple's PowerTalk, Shana Informed, and Fischer International's Workflow 2000.
