ML-KEM key exchanges using Bouncy Castle 1.79#629
Merged
Conversation
It was dropped by mistake when the plain alias was introduced in commit ff9fc91.
Avoid code duplication.
Refactor the KEM-based KEX paths a little bit; provide the ML-KEMs, and add the DH factories combining the ML-KEMs with the base curves and hashes. KexTest tests that the new key exchanges do work between an Apache MINA sshd client and server. Add an integration test that verifies that the new ML-KEM kex works against an OpenSSH 9.9 server (it only has mlkem768x25519, not the other two variants using ECDH nistp256/384, so we can't test those).

Implement ML-KEM key exchanges; see https://datatracker.ietf.org/doc/html/draft-kampanakis-curdle-ssh-pq-ke-04 .
All three algorithms proposed in that draft RFC are implemented.
Includes an interoperability test for mlkem768x25519-sha256 against OpenSSH 9.9.
Fixes #606.
