Abstract:

   This document defines the did:x509 decentralized identifier method,
   which enables a direct, resolvable binding between X.509 certificate
   chains and compact issuer identifiers (DID string).  In particular,
   the did:x509 identifier format in this documents comes with a CWT
   Claims definition.  In general, this identifier is a compact and
   interoperable mechanism for certificate-based identification by
   combining a certificate fingerprint with optional policies for
   subject names, subject alternative names, extended key usage, and
   issuer information.  It is especially useful for policy evaluation
   and reference in transparency services and similar systems requiring
   cryptographic binding to certificate material.

   This Informational document is published as an Independent Submission
   to improve interoperability with Microsoft's architecture.  It is not
   a standard nor a product of the IETF.
