RFC 1422:

A series of documents defining privacy enhancement mechanisms for electronic mail transferred using Internet mail protocols. RFC 1421 prescribes protocol extensions and processing procedures for RFC-822 mail messages, given that suitable cryptographic keys are held by originators and recipients as a necessary precondition. RFC 1423 specifies algorithms, modes and associated identifiers for use in processing privacy-enhanced messages, as called for in RFC 1421 and this document. This document defines a supporting key management architecture and infrastructure, based on public-key certificate techniques, to provide keying information to message originators and recipients. RFC 1424 provides additional specifications for services in conjunction with the key management infrastructure described herein. The key management architecture described in this document is compatible with the authentication framework described in CCITT 1988 X.509. This document goes beyond X.509 by establishing procedures and conventions for a key management infrastructure for use with Privacy Enhanced Mail (PEM) and with other protocols, from both the TCP/IP and OSI suites, in the future. There are several motivations for establishing these procedures and conventions (as opposed to relying only on the very general framework outlined in X.509).
