[secdir] Secdir last call review of draft-ietf-cose-webauthn-algorithms-06

[Linda Dunbar via Datatracker <[e-mail]>]

Reviewer: Linda Dunbar
Review result: Not Ready

I have reviewed this document as part of the security directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written primarily for the benefit of the security area directors.
 Document editors and WG chairs should treat these comments just like any other
 last call comments.

This document is to list down the COSE&JOSE Algorithms to be registered to
IANA. But it seems the description is not complete. In the Section 2: among the
4 algorithms listed under RSASSA-PKCS1-v1_5, three are NOT recommended, one is
deprecated. Under the Security Consideration (Section 5), Section 5.2 describes
why SHA-2 is "Not Recommended", Section 5.3 describes why SHA-1 is
"Deprecated".  What about the description on why SHA-512,  SHA-384, and SHA-256
are not recommended?  Is the missing description intended?

Best Regards,
