pub const PQ_KX_GROUP_NAME: &str = "X25519MLKEM768";Expand description
The canonical name of the X25519+ML-KEM hybrid key-exchange group as
rustls would register it. Used as the kx_group label on
PqHandshakeResult and in logs. The exact rustls type name may
differ when the experimental API stabilizes; this constant is the
operator-facing label.
