I have reviewed draft-ietf-cose-key-thumbprint in draft 04 form for the Operations and Managment area.

The document is ready.

One compromise that the document explicitly outlines is the non-inclusion Optional COSE Key Parameters in sgined thumbprint. while not ideal given that it cannot be asserted that this values have not been changed. The document is clear that this is a compromise and is fundamentaly a judgement call that would otherwise result in compatibility considerations when the optional parameters are unavailable of cannot be parsed.
