### Stream header
The pseudo-random tag is followed by the stream header, which consists of a random nonce followed by an ephemeral key encrypted and authenticated with the sender's outgoing header key and the nonce. The stream header is NONCE_LEN + KEY_LEN + AUTH_LEN bytes long. The ephemeral key is used for encrypting and authenticating the rest of the stream.
