prevent screenshots or copying from an encrypted chat
Aside from the obvious analog hole, that’s only possible if the user’s device cooperates, which is never guaranteed.
There is no way to send messages to someone’s device and guarantee they won’t provide them to a third party. Technology can’t force an untrustworthy person to keep your secrets.
Signal does not attempt to stop me from taking screenshots, and all chats on Signal are encrypted.
You have some good points. I’m curious about the scenario where you need encrypted communications with an untrusted party.
I guess if you are leaking insider information to the press and need to be anonymous, but then use an anonymous account. Why would you need to send information to someone but not trust them to use the information responsibly?
