So, I’m interested how the implementation of “Perfect Forward Secrecy” in Signal looks like, like does every messages has a different encryption key? or does it change over time like #whatsapp does? I tried to find any official documention of this, sadly did not find anything.

Thats why I’m asking, does anyone of you know smth about this and maybe can provide a link to a official source?

      I don’t know if I fully understand you here.

      To my understanding whatsapp does it like this too. The key changing must be the high level key, since the message means that it’s an unknown key (thus not yet trusted). From new install or new device.
