This document specifies conventions for X.509 certificate usage by
Secure/Multipurpose Internet Mail Extensions (S/MIME) agents.
provides a method to send and receive secure MIME messages, and
certificates are an integral part of S/MIME agent processing.
S/MIME agents validate certificates as described in RFC 3280bis, the
Internet X.509 Public Key Infrastructure Certificate and CRL
S/MIME agents must meet the certificate processing requirements in
this document as well as those in RFC 3280bis. This document
obsoletes RFC 3850.
