The greatest cryptography is analogy.
If you have a god-like computer, you can "break" all cryptography, since it's all objective.
Analogies are subjective and you can't "break" them if you don't have the key.
That's why ancient/old analogies survived until today.
The wise ones used to communicate in analogies so they wouldn't get burned alive by the church some hundred years ago or be murdered by the local establishment thousands of years ago.
