1. Executive Summary

   This document describes three types of service in support of Internet
   Privacy-Enhanced Mail (PEM) [1-3]: key certification, certificate-
   revocation list (CRL) storage, and CRL retrieval. Such services are
   among those required of an RFC 1422 [2] certification authority.
   Other services such as certificate revocation and certificate
   retrieval are left to the certification authority to define, although
   they may be based on the services described in this document.

   Each service involves an electronic-mail request and an electronic-
   mail reply. The request is either an RFC 1421 [1] privacy-enhanced
   message or a message with a new syntax defined in this document. The
   new syntax follows the general RFC 1421 syntax but has a different
   process type, thereby distinguishing it from ordinary privacy-
   enhanced messages. The reply is either an RFC 1421 privacy-enhanced
   message, or an ordinary unstructured message.

   Replies that are privacy-enhanced messages can be processed like any
   other privacy-enhanced message, so that the new certificate or the
   retrieved CRLs can be inserted into the requestor's database during
