As long as Software exists people will attempt to crack it -- not always for money but a challenge.
Is there a totally 100% escape proof prison anywhere in the world -- probably not -- doesn't matter what security is implemented humans are fallable (and bribable) so technology alone will NEVER solve this problem.
One possible proviso -- if a Quantum Computer ever becomes a reality then no encryption we currently know about will ever be possible since even a "brute force attack" with even large power 200 digit numbers as keys (more atoms than exist in the entire universe) can be cracked in seconds. -- For those that don't know a quantum computer can process an infinite number of calculations IN PARALLEL and complete these in a very short time.
Instead of a Binary state being 0 or 1 a quantum bit can be 0, 1, or BOTH at the same time .
