Purpose: In response

Referenced liaison: LS to IETF TLS WG – asking for RFC publication timeline of Post-quantum hybrid ECDHE-MLKEM Key Agreement active internet draft (https://datatracker.ietf.org/liaison/2002/)

Body: Thank you for reaching out and sending your request to us! We apologise for missing the deadline but hope the information in this reply is still valuable in the preparation of your upcoming meeting!

The draft on Post-quantum hybrid ECDHE-MLKEM Key Agreement for TLSv1.3 (https://datatracker.ietf.org/doc/draft-ietf-tls-ecdhe-mlkem/) is an adopted working group item since March 2025 and has been stable for some time, even to the extent that it is already deployed in some cases. Therefore we believe this document is stable enough to be used as normative reference. Referencing an adopted draft normatively is a practice that other organisation follow as well and we concur with, particularly in this case.

If you prefer to wait for the final RFC before you reference it normatively, we are optimistic to begin the progress by Q4 of 2025 but as the IETF does not work on firm deadline, we cannot guarantee the timing at this point of time. Note that after approval there is another formal editing phase where the RFC number is assigned before the RFC is published and this will then likely be after Q4 of 2025.

In any case please feel free to reach out for any further questions or directly contact the working group chairs, Sean Turner and Joe Saloway, for a quicker turn over on any particular questions!
