Re: @AC "11 mins" whatever that means, ElReg (was:Whatever.)
It's not the encryption that's the weak link. If your data is somewhere that it is accessible then it is vulnerable no matter what you do and the protections of the protocol used to access it are useless unless they are known only by you.
If you manage to store data in a form where it really can't be decrypted or the protections bypassed then it's clear that you really have something to hide and you will be threatened badly by the players in the game if they deem it important enough.
Standing up to the power that a state can command is really difficult, it's almost certainly not worth it if you need to be able to set foot in most Western countries.
