Hash functions map plaintext to hashes so that you can't tell a plaintext from its hash.

If you want to find a given plaintext for a certain hash there are two simple methods:
- Hash each plaintext one by one, until you find the hash.
- Hash each plaintext one by one, but store each generated hash in a sorted table so that you can easily look the hash up later without generating the hashes again
