Abstract

   This document contains a set of updates to the base syntax and
   transport of Certificate Management Protocol (CMP) version 2.  This

   Specifically, the CMP services updated in this document comprise the
   enabling of using EnvelopedData instead of EncryptedValue, the
   definition of extended key usages to identify certificates of CMP
   endpoints on certification and registration authorities, and adds an
   HTTP URI discovery mechanism and extend the URI structure.
