The CBOR Object Signing and Encryption (COSE) syntax [I-D.ietf-cose-rfc8152bis-struct] allows for adding additional algorithms to the registries. This document adds one additional key wrap algorithm to the registry using the AES Wrap with Padding Algorithm [RFC5649]. This document adds Keccak Message Authentication Code (KMAC) algorithms as well as using KMAC as a Key Derivation Function (KDF).
