Technical Summary This protocol provides an X.509 public key certificate extension to indicate the end entity's S/MIME cryptographic capabilities. It is an optional, non-critical extension. Working Group Summary Initially, the major discussion point was whether this mechanism, which is considered a "static" mechanism, is better or worse than a more "dynamic" mechanism, which could change without affecting the public key certificates contents. The WG decided to allow for the possibility of another editor could step for to define the "dynamic" mechanism, but that this "static" mechanism should be allowed to proceed. The other discussions on the draft were considered minor, mostly dealt with the security considerations wording, and these issues were resolved quickly. Protocol Quality The protocol is implemented by one vendor already in a number of their products. This document was reviewed by Russ Housley for the IESG.
