CFRG ZK call and RFC ops debate

CFRG opened an adoption call for a zero-knowledge draft while an OPSAWG last call drew broad pushback on mandatory operational sections. DKIM operators flagged header growth risks and PLANTS weighed MTC use-case text.

CFRG call for Longfellow ZK adoption

The CFRG opened a two-week call for adoption of draft-google-cfrg-libzk-03 (Longfellow ZK). Multiple implementers voiced support across the thread. Cryptography developers should track whether the group advances the work toward a CFRG document.

Pushback on mandatory Operational Considerations

IETF last call on draft-ietf-opsawg-rfc5706bis-09 produced broad opposition from key participants to requiring Operational Considerations sections in new RFCs. The OPSAWG discussion ran hot with many contributors. The outcome will shape how future RFCs document deployment realities.

DKIM BCP note on header size limits

A DKIM2 thread proposes BCP text that flags header size limits and truncation risks from growing Message-Instance and DKIM2-Signature fields. Operators raised the issue as Message-Instance growth continues. Mail-system implementers need to watch for interoperability breakage.

PLANTS adoption call for MTC use cases

The PLANTS working group ran a call for adoption of draft-gray-plants-mtc-deploy-use-cases-01, which explores MTC scenarios beyond WebPKI. Most participants supported adoption. The draft would expand the charter conversation if taken up.
