I believe this document should be an Informational RFC as indicated in the
title page.

This document defines a set of hash algorithms that are identified by COSE
Algorithm Identifiers. It also provides two examples of structures for holding
a hash value.

The document has had clear working group consensus for publication and it has
been reviewed by a few working group participants since its adoption.

John Mattsson has reviewed an early version of the document. Kathleen Moriarty
did a review of a pre-working group last call version of the document. Ludwig
Seitz and Ivaylo Petrov did a review on the working group last call version of
the document. All the review issues have been addressed and no review comments
or issues are currently pending.

I completed a detailed review of the document. All of my remarks were processed
and there are no remaining open issues.

No, given the number of reviews and the relative shortness of the document, I
believe it has had sufficient reviews.

No.

No concerns or issues.

Yes, the authors have confirmed that they are not aware of any IPR.

No IPR.

From my perspective the WG understands and agrees with the proposed draft
without any other alternatives being provided.

No.

From reading the document, there is section "Contributing to this document"
that would need to be removed as indicated in the text. As this section is
meant to be remove by the RFC editor, I believe they should not block the
document from progressing.

ID nits points out that
- there is a reference to a document in the abstract, which should be replaced
  with textual description
- two of the internet drafts that this document references have undergone a new
  revision

I believe those issues will only require minor editorial changes, which does
not seem as a sufficient reason to delay the progress of the document.

I am not aware of any formal review criteria that apply to this document. The
hash algorithms for which it defines COSE Algorithm Identifiers have passed
formal review.

Yes.

Only draft-ietf-cose-rfc8152bis-struct is a work in progress. It is past WGLC
which made this feel acceptable.

There are no downward normative references.

No.

The document adds a number of values to COSE Algorithms Registry. For those all
the necessary information is provided.

No new IANA registries.

There are only two instances of code snippets that are given as examples. There
is no definition of the formal format that they follow and they are left for
interpretation to the reader. The snippets seem compatible with CDDL as
specified by RFC8610 and follow the same format as the snippets in RFC 8152. I
believe a minor editorial change might be needed to explicitly state that, but
this change does not need to delay the progress of this document.

No YANG modules are defined by this document.
