"Since speed is a concern, I think that the proposal to avoid using the random hash for short strings is a good idea."

My proposition only adds two XOR to hash(str) (outside the loop on Unicode characters), so I expect a ridiculous overhead. I don't know yet how hard it is to guess the secret from hash(str) output.
