Correctly derive the SSID
Created by: claucece
As we are currently implementing the revision number 2 of the OTRv4 specification, we need to clarify how to correctly derive the Secure Session ID (SSID).
As defined in the OTRv4 specification, section "Secure Session ID".
- Check that the number of bytes this value has (8-byte) and change it accordingly in the library.
- Check that there is correct functionality for when a participant requests to see it.
- Check that it is correctly derived on both DAKEs.
- Check that it is part of the secret information for the SMP.
