 The authenticated key agreement (`Noise_XK`) is performed in three distinct

 material is sent to the other party, an `ECDH` is performed based on exactly

 encryption keys (`ck` the chaining key and `k` the encryption key), and finally
 an `AEAD` payload with a zero length cipher text is sent.  As this payload is
 of length zero, only a `MAC` is sent across.  The mixing of `ECDH` outputs into
