    They can log anything they want and have nothing useful, if the encryption protocol is sound.
    Have a look at how TLS is designed, if you want to know more.

      I know my way around cryptography, therefor I am skeptical. If push comes to shove, they can simply command the Whatsapp App to silently surrender the keys. Nobody would know, it is a closed source app and protocol, and they can hide what they are doing inside the (probably) TLS encrypted stream.

        But the key exchange is not the issue then.
        Access to private keys is.
        If the host system, on which the key exchange runs, is compromised, you’re toast.

          Where’s the private key? I can get a new phone, log with WhatsApp and download all the historical messages without intruducing any additional password or key.

          I assume they have all the required data too.

            @Railcar8095 @zergtoshi actually is not my exlerience with whatsapp, since I have the backups disable, everytime I change phones I lost all my conversations. But since whatsapp is closed source, the app can indeed use encryption to comunicate p2p, but I will allways assume that the key is logged by meta, “just in case”

            Sounds like a compromised phone in the sense that it doesn’t protect (and instead transmit) the private key.
