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?

    It’s no secret that WhatsApp adopted Signal’s encryption protocol just before Meta acquired them, but since it’s all closed source we don’t know if they’ve changed anything since the announcement in 2016 that all forms of communications on WhatsApp are now encrypted and rolled out.

    There is an Open Source implementation of the WhatsApp protocol: yowsup
