Open Source Encrypted Messenger

Well, I don't use WhatsApp and I don't use FB for anything even remotely important. ;)

Thing about WhatsApp and FB is that they're not trumpeting how wonderful and secure they are, while Telegram is talking up how secure they are - but an examination of their security suggests it's not so secure.

They're breaking one of *the* cardinal rules - don't roll your own crypto.
