After a long weekend, I've finally updated https://publickey.directory to reflect the current state of affairs for the Public Key Directory which brings Key Transparency to the Fediverse, as part of the effort to build End-to-End Encryption (E2EE) for ActivityPub.
This project now supports* Post-Quantum Cryptography! (We're shipping ML-DSA-44 now and will consider new algorithms in the future.) HPKE also uses mlkem768x25519 (a.k.a. X-Wing).
* The only part that doesn't currently require post-quantum cryptography is RFC 9421 (HTTP Message Signatures), because no one has bothered to specify an IANA codepoint for it yet. I'm planning to write a C2SP spec soon if no one beats me to it. For the interim, Ed25519 is still allowed there, but in v2 I plan to drop it.
