Abstract Abstract
The CBOR Object Signing and Encryption (COSE) syntax The CBOR Object Signing and Encryption (COSE) syntax
[I-D.ietf-cose-rfc8152bis-struct] does not define any direct methods [I-D.ietf-cose-rfc8152bis-struct] does not define any direct methods
for using hash algorithms. There are, however, circumstances where for using hash algorithms. There are, however, circumstances where
hash algorithms are used, such as indirect signatures where the hash hash algorithms are used, such as indirect signatures where the hash
of one or more contents are signed, and X.509 certificate or other of one or more contents are signed, and X.509 certificate or other
object identification by the use of a fingerprint. This document object identification by the use of a fingerprint. This document
defines a set of hash algorithms that are identified by COSE defines a set of hash algorithms that are identified by COSE
