This specification defines a method for computing a hash value over a
CBOR Object Signing and Encryption (COSE) Key. It specifies which
fields within the COSE Key structure are included in the
cryptographic hash computation, the process for creating a canonical
representation of these fields, and how to hash the resulting byte
sequence. The resulting hash value, referred to as a "thumbprint",
can be used to identify or select the corresponding key.

This document is a product of the CBOR Object Signing and Encryption Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
