            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.
