Abstract​

This specification defines fully-specified cryptographic algorithm identifiers for registered JSON Object Signing and Encryption (JOSE) and CBOR Object Signing and Encryption (COSE) polymorphic algorithm identifiers. It enables applications to use only fully-specified algorithm identifiers and deprecates the polymorphic identifiers it replaces.
