Forgive me if this is an obvious stupid question, but with all this talk (again) about the EU trying to force chat platforms to check the content of its messages, I can help but think: how are they ever going to prevent me and my friend from sharing public keys and using them to encrypt our messages to each other? In other words: how are they ever going to be able to ban encryption?
You don’t even have to do it with pen and paper. You can install whatever operating system and software you want on your computer. If blocking certain resources on the internet is an issue, you could torrent public keys, use tor, use i2p, or worst case scenario deliver a USB drive to your friend’s door.
One time pads can be used in public message apps or irc nothing they can do about it
Yup
