A question about secure chats
(sopuli.xyz)
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?
for clarity, i think that the worst thing anyone’s been able to decisively prove about telegrams encryption is that it’s vulnerable to replay attacks… which in the context of privacy rather than full security isn’t suuuuper problematic
that’s not to say that there aren’t other flaws; that’s kinda the point behind “rule number 1: DONT INVENT YOUR OWN CRYPTO”: you just don’t know what flaws there are… AES (etc) has had a LOT of eyes on it
but for the most part, the negativity with the crypto boils down to what-ifs
IIRC Telegram is only e2e if you explicitly enable it, and not at all for group chats. My info is probably (and hopefully) outdated though.
And E2EE is only available on phones, circa a couple of years ago anyways
yeah that’s also correct and a very valid criticism
