Re: [Spasm] Fwd: New Version Notification for draft-wconner-blake2sigs-00.txt

[Jim Schaad <[e-mail]>]

Just some really fast first impressions.

 

1.	What is the opinion of CFRG for Blake?   I note that the algorithm definition is published as an Independent stream document and I don’t remember getting any CFRG review at the time.
2.	Please don’t do PKCS v1.5 signatures.  We need to make these go away.
3.	This seems to have a lot of TBD work that is not marked as such.

Abstract:
   This document describes the conventions for using the BLAKE2b-512
   hash function with each of the following signature algorithms: RSA
   Public-Key Cryptography Standards #1 version 1.5 (RSA PKCS#1 v1.5),
   RSA Probabilistic Signature Scheme (RSASSA-PSS), RSA Encryption
   Scheme - Optimal Asymmetric Encryption Padding (RSAES-OAEP), Elliptic
   Curve Digital Signature Algorithm (ECDSA), and Edwards-curve Digital
   Signature Algorithm (EdDSA).  This specification applies to the
   Internet X.509 Public Key Infrastructure (PKI) when digital
   signatures are used to sign certificates and certificate revocation
   lists (CRLs).  This document also specifies the object identifiers
   (OIDs) for the combinations of the BLAKE2b-512 hash function with the
   aforementioned signature algorithms.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org <http://tools.ietf.org> .
