Abstract:
This document specifies a CBOR encoding of X.509 certificates. The
resulting certificates are called C509 Certificates. The CBOR
encoding supports a large subset of RFC 5280 and all certificates
compatible with the RFC 7925, IEEE 802.1AR (DevID), CNSA, and CA/
Browser Forum Baseline Requirements profiles. When used to re-encode
DER encoded X.509 certificates, the CBOR encoding can in many cases
reduce the size of RFC 7925 profiled certificates with over 50%. The
CBOR encoded structure can alternatively be signed directly
("natively signed"), which does not require re-encoding for the
signature to be verified. The document also specifies COSE headers
as well as a TLS certificate type for C509 certificates.
