Perfect, thanks.

Any plans to support Bernstein's gear:

    ...

    enum {
        rsa(1), ecdsap256(3), (255)
    } SignatureAlgorithm;
    ...

    enum {
        secp256r1 (23), (0xFFFF)
    } NamedCurve;

Should there be a ed25519 or similar?

To be clear, I'm interested in using it to stop MitM due to gaps in
existing controls in some security models, and not stop the triple
handshake threat.
