This document defines Secure/Multipurpose Internet Mail Extensions
(S/MIME) version 3.1.  S/MIME provides a consistent way to send and
receive secure MIME data.  Digital signatures provide authentication,
message integrity, and non-repudiation with proof of origin.
Encryption provides data confidentiality.  Compression can be used to
reduce data size.  This document obsoletes RFC 2633.
