The specification Using RSA Algorithms with COSE Messages defines encodings for using RSA algorithms with CBOR Object Signing and Encryption (COSE) messages. This supports use cases for the FIDO Alliance and others that need this functionality. Security Area Director Kathleen Moriarty has agreed to AD sponsorship of this specification. This specification incorporates text from draft-ietf-cose-msg-05 – the last COSE specification version before the RSA algorithms were removed.
