  Tox also isn’t that great security wise. It’s hard to beat Signal when it comes to security messengers. And Signal is open source so

    And Signal is open source so, if it did anything weird with private keys, everyone would know

    Well, no. At least not by default as you are running a compiled version of it. Someone could inject code you don’t know anything about before compilation that for example leaked your keys.

    One way to be more confident no one has, would be to have predictable builds that you can recreate and then compare the file fingerprints. But I do not think that is possible, at least on android, as google holds they signature keys to apps.

      Signal has reproducible builds and here’s the instruction how to check it on Android github.com/signalapp/Signal-Android/…/README.md

    Well, Whatsapp uses signal. Bad timing

      It only uses some of signal’s code. Not necessarily the OOTB key storage and security.

        WhatsApp is using Signals protocol for communication: signal.org/blog/whatsapp-complete/

        I don’t fully understand what it entails, but from what I understand is that yes, WhatsApp is using the same encryption and message flow that signal uses, but you’re still using Meta’s app, and they can just read the plaintext message from there.

  What’s stopping the app from keeping your private key and still not encrypting anything?

  I’m not trying to be difficult here, I just don’t see how anything outside of an application whose source you can check yourself can be trusted.

  All applications hosted by other people require you to react positively to “just trust me bro”.

    Or, if the app has the private key for decryption for the user to be able to see the messages, what’s stopping the app from copying that decrypted text somewhere else?

    The thread model isn’t usually key management, it’s more about the insecure treatment of the decrypted message after decryption.

  What’s to stop an evil company uploading the keys after you enter them in the App? It certainly wouldn’t stop Meta.

  Man, you just brought back memories. I forgot qtox was even a thing. I think I still have my profile saved in my dev folder somewhere for my account
