[noise] Using X25519 keypair obtained by Ed25519 conversion

[David Wong]

Two questions. After conversion you should have a key pair (priv, pub):

1. are you loading the initiator with that new pub?
2. are you loading the responder with that key pair? And did you
verify that pub can be obtained from priv?
