It is currently a jail-able offence to not reveal an encryption key when demanded - even when it is not possible to prove that there is anything encrypted
This law is totally untested in the higher courts, and is the antithesis of various parts of fundamental UK constitutional law. Every time it's ever looked like being tested the governments that have been around since it's been enacted have ran away screaming - it's only there to scare people into cooperation.
