Technical Summary
This document specifies the conventions for X.509 certificates
for use with S/MIME agents. It is the third update of the S/MIME
Certificate Handling specification (aka S/MIME CERT v3.2) and it
will obsolete RFC 3850, when approved. Note that Annex A
recommends moving RFC2312, which is S/MIME CERT v2, to historic
status.
Working Group Summary
The majority of the S/MIME WG discussion was on what key sizes
and which algorithms to support. The initial proposal included
ECC algorithms as SHOULDs, but they were removed. After removal
of the ECC algorithms, the S/MIME WG quickly reached a concensus
on the algorithms. The key size discussion had two camps "go big"
and "be realistic". The rough consensus is somewhere in the
middle and is supported by widely deployed implementations.
Document Quality
S/MIME has numerous implementations. In fact, many implementations
already support the algorithms and key sizes specied in this
document, with the exception of RSA-PSS.
Personnel
Russ Housley is the document Shepherd.
Tim Polk is the responsible Security Area AD.
