You don't need to know the plaintext, just be able to algorithmically
distinguish it from pseudorandom bits.
a way of getting it to evaluate the encryption function in a reversible
manner must be found (Probably not difficult).
Trivial. Building the computer is the only hard part here. That and the 2^256 complexity of the attack, of course.
