  "abstract": "This document defines a post-quantum public key algorithm extension for the OpenPGP protocol, extending RFC 9580. 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 (ECC), and SLH-DSA (formerly SPHINCS+) as a standalone public key signature scheme.",
