Hi, We have updated the draft "Post-Quantum and Hybrid KEMs for HPKE with JOSE and COSE" https://datatracker.ietf.org/doc/draft-reddy-cose-jose-pqc-hybrid-hpke/ to version 10. As many of you recall, this draft has been presented multiple times in both COSE/JOSE WGs. While there was general interest, the WG adoption of this draft was previously postponed to allow for the completion COSE-HPKE and JOSE-HPKE specifications.
With those base documents now mature, we have updated this draft to ensure alignment with, JOSE/COSE HPKE and HPKE PQ specs. Further, comments and suggestions are welcome. we also request the Chairs to initiate a second WG adoption call for this draft.

It defines algorithm identifiers and key formats to support pure post- quantum algorithms (ML-KEM) and their PQ/T hybrid combinations. The IETF Secretariat
