Abstract

   This document describes the conventions for using several
   cryptographic algorithms with the Certificate Management Protocol
   (CMP).  CMP is used to enroll and further manage the lifecycle of
   X.509 certificates.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
