1423: Privacy Enhancement for Internet Electronic Mail: Part III: Algorithms, Modes, and Identifiers.

This document provides definitions, formats, references, and citations for cryptographic algorithms, usage modes, and associated identifiers and parameters used in support of Privacy Enhanced Mail (PEM) in the Internet community. It is intended to become one member of the set of related PEM RFCs. This document is organized into four primary sections, dealing with message encryption algorithms, message integrity check algorithms, symmetric key management algorithms, and asymmetric key management algorithms (including both asymmetric encryption and asymmetric signature algorithms).
