I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. draft-housley-rfc5008bis-00 obsoletes RFC 5008 which defines suite B algorithms for use in S/MIME. I don't see any issues with the contents of the document or the security considerations section.
