I'm not a lawyer, and I don't live in the EU. Sorry for the silly question.

Is there any EU law that prohibits minors from encrypting their messages or using, for example, PGP keys?

How can they protect children if the children deliberately encrypt their messages?

No, there is no law preventing anyone from encrypting their messages. The thought is that children won't use encrypted services.
