It would not take a human cryptographer years to break that system, let alone a computer. Even without the algorithm, if you have access to multiple passwords and what they are converted to, it would not take that long to determine the algorithm.

Let me simplify greatly (it's not THIS easy, but it illustrates the issue)...

What is 6x6? 36
What is 4x9? 36
What is 2x18? 36

If I told you that the question (algorithm) was AxB, and told you the answer (encryption) was 36 ... can you tell me, for sure, what A and B is? No.
