Abstract

   This memo specifies how to incorporate International Data Encryption
   Algorithm (IDEA) into CMS or S/MIME as an additional strong algorithm
   for symmetric encryption.  For organizations who make use of IDEA for
   data security purposes it is of high interest that IDEA is also
   available in S/MIME.  The intention of this memo is to provide the
   OIDs and algorithms required that IDEA can be included in S/MIME for
   symmetric content and key encryption.

1. Introduction

   This memo specifies how to incorporate International Data Encryption
   Algorithm (IDEA) [IDEA] into CMS or S/MIME [SMIME2, SMIME3] as an
   additional strong algorithm for symmetric encryption.  For
   organizations who make use of IDEA for data security purposes it is
   of high interest that IDEA is also available in S/MIME.  The
   intention of this memo is to provide the OIDs and algorithms required
   that IDEA can be included in S/MIME for symmetric content and key
   encryption.

   The general functional capabilities and preferences of S/MIME are
   specified by the registered list of S/MIME object identifiers (OIDs).
   This list of OIDs is available from the Internet Mail Consortium at
   .  The set of S/MIME
   functions provided by a client is expressed by the S/MIME
   capabilities attribute.  This attribute contains a list of OIDs of
   supported cryptographic functions.
