Two questions.

My family insist on using Whatsapp for the family chats. I have to keep a copy on a device just so I can communicate with them. I do so under protest, as I was always told it isn’t secure. My brother has just said

“oh Whatsapp is encrypted, it’s perfectly secure”.

First, is it actually as encrypted and safe as my brother claims? That would solve everything.

Second, if it isn’t, where can I get some proof that we should switch to Telegram or whatever? Proof which doesn’t make me look like a raving loony?

    To “link” other devices you have to scan a qr from your phone, so it’s certainly possible that during that process the devices connect and share the key, and the servers don’t have it.

    Or the servers could have it. Idk, it’s closed source, that’s the problem at hand.

      Sounds like it transfers the ID Out-of-band, so that’s good, does the desktop get the chat history then? (It’s possible it pulls chat history from the phone).

      Oh, I agree with the closed source issue. That makes it a no-sale for me.

      No, the protocol is sound enough, WhatsApp doesn’t have the key, doesn’t want the key (so they will probably not be responsible for what you are communicating with others), and doesn’t need the key - as others have put so eloquently, the metadata is rich enough for them.
