Technical Summary

   This document specifies the Cryptographic Message Syntax (CMS),
   which is used to digitally sign, digest, authenticate, or encrypt
   arbitrary message content.  

Working Group Summary

   RFC 5652 was a product of the smime working group.
   CMS is widely referenced, and is a key building block for
   specifications developed by the S/MIME, ltans, and keyprov
   working groups.

Document Quality

   The community has accumulated significant operational experience
   with the Cryptographic Message Syntax in a variety of security 
   protocols.  The technical maturity and high level of confidence is
   clearly demonstrated by the continued use of CMS as a building
   block for these standards efforts.

   Two or more interoperable implementations were identified for
   all features when this specification was promoted to Draft Standard.
