    abstract =  {S/MIME (Secure/Multipurpose Internet Mail Extensions), described in {[}SMIME-MSG{]}, provides a method to send and receive secure MIME messages. Before using a public key to provide security services, the S/MIME agent MUST certify that the public key is valid.

S/MIME agents MUST meet the certificate processing requirements documented in this document in addition to those stated in {[}KEYM{]}.},
