1. Introduction

   "Credentials" are information that can be used to establish the
   identity of an entity, or help that entity communicate securely.
   Credentials include such things as private keys, trusted roots,
   tickets, or the private part of a Personal Security Environment (PSE)
   [RFC 2510] - that is, information used in secure communication on the
   Internet.  Credentials are used to support various Internet
   protocols, e.g., S/MIME, IPSec and TLS.
