Lots and lots of math. I dont believe the program to black box ofuscator/encryptor has come to fruition yet. But lattice methods were teasing it out. We do have homomorphic encryption that allows for basic operations like addition and multiplication on the ciphertext. But not turing complete black boxed behavior. Thats a twinkle to aim for.
