The IESG has received a request from the Public-Key Infrastructure (X.509) WG (pkix) to consider the following document: - 'S/MIME Capabilities for Public Key Definitions' <draft-ietf-pkix-pubkey-caps-04.txt> as an Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-04-20. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document defines a set of S/MIME Capability types for ASN.1 encoding for the current set of public keys define in the PKIX working group. This facilitates the ability for a requester to specify information on the public keys and signature algorithms to be used in responses. An example of where this is used is with the OCSP Agility draft. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-pkix-pubkey-caps/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-pkix-pubkey-caps/ballot/ No IPR declarations have been submitted directly on this I-D.
