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?

    WhatsApp uses the encryption protocol developed for Signal, so I’d not expect them to be significantly different.

      @Rose True, but there are still differences, for example Signal encrypts everything, while WA only encrypts chats and calls, so the implementation is a bit different, which maybe could be also in Signal with PFS.

        The main advantages of Signal over WA is that Signal minimises the amount of metadata Signal has access to and promises to not store or analyse the little remaining metadata.

        The data (as in: the actual message content) should be similarly secure in both.
