Certificate Management Protocol (CMP) Algorithms
draft-ietf-lamps-cmp-algorithms-03
Abstract
This document describes the conventions for using concrete
cryptographic algorithms with the Certificate Management Protocol
(CMP). CMP is used to enroll and further manage the lifecycle of
X.509 certificates.
