Hi Torsten, Unfortunately, the description you link to does not satisfy my question because it does not describe the full signal protocol. It is lacking, at least:
1. A description of the four-way Diffie-Hellman handshake (or any authenticated key exchange at all), 2. The involvement of the short-term signed pre-key in addition to the one-time-use pre-key.
