Hash function that produces short hashes?

Question

Is there a way of encryption that can take a string of any length and produce a sub-10-character hash? I want to produce reasonably unique ID\'s but based on message content

Answer 1

If you don't need an algorithm that's strong against intentional modification, I've found an algorithm called adler32 that produces pretty short (~8 character) results. Choose it from the dropdown here to try it out:
