"I need something like this"

What makes you think you need this? It's probably the worst checksum algorithm I've ever seen. Not everything you find on the web is a good idea.

In any case, if you really need this algorithm, why don't you implement it? It's trivial. it tells you it's the 2's compliment of addition of all bytes (mispelling courtesy of the original author!)
