Abstract

The CBOR Object Signing and Encryption (COSE) syntax (see RFC 9052)does not define any direct methods for using hash algorithms. Thereare, however, circumstances where hash algorithms are used, such asindirect signatures, where the hash of one or more contents aresigned, and identification of an X.509 certificate or other object bythe use of a fingerprint. This document defines hash algorithms thatare identified by COSE algorithm identifiers.
