Hi Russ,

I was under the impression that SHAKEs for CMS and X.509 would suffice for introducing the Keccak family to these standards. SHAKEs have the same security and better performance. I thought that was the reason draft-turner-lamps-adding-sha3-to-pkix never made it.

Is there a reason why someone would use SHA-3 in CMS instead of SHAKE128 or SHAKE256 (RFC8702)?

Hello,

Russ has asked for an adoption call for this short document that explains how to
use SHA-3 with CMS.  Since people may be traveling to IETF 118, we'll do a three
week adoption call.


https://datatracker.ietf.org/doc/html/draft-housley-lamps-cms-sha3-hash-00

Abstract

   This document describes the conventions for using the four one-way
   hash functions in the SHA3 family with the Cryptographic Message
   Syntax (CMS).

Please indicate whether you support adoption, and optionally indicate why, on
the list by 17 November 2023.

For the chairs,

-Tim
