For open source messengers, you can check whether they actually encrypt your messages and whether the server has access to your encryption keys but what about WhatsApp? Since it’s not open source, you can’t be sure that the encryption keys aren’t sent to the server, right? Has there been a case where a government was able to access WhatsApp chats without reading them from the phone itself?

    So, I looked it up and according to the official Whatsapp FAQ, the keys are indeed stored locally.

    WhatsApp has no ability to see the content of messages or listen to calls that are end-to-end encrypted. That’s because the encryption and decryption of messages sent and received on WhatsApp occurs entirely on your device. Before a message ever leaves your device, it’s secured with a cryptographic lock, and only the recipient has the keys. In addition, the keys change with every single message that’s sent.

    Still, considering WhatsApp is owned by Facebook, I wouldn’t trust them. Their whole business model has always been about harvesting as much data as they can. I wouldn’t be surprised if this turns out to be a total lie.

      For sure they’re not trustworthy and can’t really verify either since it’s proprietary app. But I mean more that unless they’ve specifically made some changes, the keys are stored locally. And afaik we don’t really know of cases proving that they are lying about that.

        Fair enough, I guess. Still, in my honest opinion, it’s not worth it. They’ve already long since betrayed my trust, so they could say the sky is blue and I still wouldn’t trust them. Lol.
