[openpgp] Last Call: <draft-ietf-openpgp-pqc-13.txt> (Post-Quantum Cryptography in OpenPGP) to Proposed Standard

The IESG has received a request from the Open Specification for Pretty Good
Privacy WG (openpgp) to consider the following document: - 'Post-Quantum
Cryptography in OpenPGP'
  <draft-ietf-openpgp-pqc-13.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
[email protected] mailing lists by 2025-10-28. Exceptionally, comments may
be sent to [email protected] instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   This document defines a post-quantum public-key algorithm extension
   for the OpenPGP protocol.  Given the generally assumed threat of a
   cryptographically relevant quantum computer, this extension provides
   a basis for long-term secure OpenPGP signatures and ciphertexts.
   Specifically, it defines composite public-key encryption based on ML-
   KEM (formerly CRYSTALS-Kyber), composite public-key signatures based
   on ML-DSA (formerly CRYSTALS-Dilithium), both in combination with
   elliptic curve cryptography, and SLH-DSA (formerly SPHINCS+) as a
   standalone public key signature scheme.
