    abstract =  {This specification defines a method for computing a hash value over a COSE Key. It defines which fields in a COSE Key structure are used in the hash computation, the method of creating a canonical form of the fields, and how to hash the byte sequence. The resulting hash value can be used for identifying or selecting a key that is the subject of the thumbprint.},
