    The current re-keying procedure does allow an attacker knowing the current symmetric cipher key while not knowing the session-id (derived from the ECDH secret) to "survive" the re-keying.

    This will slightly increase the prediction resistance.

    Also includes a ugly typo in the hkdf key. Reported by @ccjj.
