Abstract

   This document describes a protocol for adding cryptographic signature
   and encryption services to X.400 content with Secure/Multipurpose
   Internet Mail Extensions (S/MIME).

1.  Introduction

   The techniques described in the Cryptographic Message Syntax [CMS]
   specification are general enough to support many different content
   types.  The [CMS] specification thus provides many options for
   providing different security mechanisms.  In order to ensure
   interoperability of systems within the X.400 community, it is
   necessary to specify the use of CMS features to protect X.400 content
   (called "CMS-X.400" in this document).

1.1.  Specification Overview

   This document is intended to be similar to the S/MIME Version 3.1
   Message Specification [MSG] except that it is tailored to the
   requirements of X.400 content rather than Multipurpose Internet Mail
   Extensions (MIME).
