The document currently requests registration of the "ckt" (COSE Key Thumbprint) confirmation method as follows: * Confirmation Method Name: ckt * Confirmation Method Description: COSE Key Thumbprint * JWT Confirmation Method Name: jkt * Confirmation Key: [[TBD1]] * Confirmation Value Type(s): binary string * Change Controller: IESG * Specification Document(s): [[This document]] This is not parallel to the "jkt" (JWK SHA-256 Thumbprint) registration at https://www.iana.org/assignments/jwt/jwt.xhtml#confirmation-methods, in that it doesn't include the hash function. Please change "COSE Key Thumbprint" to "COSE Key Thumbprint using SHA-256 Hash Function".

Please send substantive comments to the last-call@xxxxxxxx mailing lists by 2024-04-02. Exceptionally, comments may be sent to iesg@xxxxxxxx instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-cose-key-thumbprint/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references.
