Abstract

In the process of dealing with the Online Certificate Status Protocol (OCSP) agility issues in [RFC6277], it was noted that we really wanted to describe information to be used in selecting a public key, but we did not have any way of doing so. This document fills that hole by defining a set of Secure/Multipurpose Internet Mail Extensions (S/MIME) Capability types for a small set of public key representations.

              S/MIME Capabilities for Public Key Definitions

Abstract

   This document defines a set of Secure/Multipurpose Internet Mail    Extensions (S/MIME) Capability types for ASN.1 encoding for the    current set of public keys defined by 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.    "Online Certificate Status Protocol Algorithm Agility" (RFC 6277)    details an example of where this is used.
