Maybe Chris's phrasing misled you: I didn't invent the Whirlpool algorithm
And so it did; something a quick google would have revealed. In my defense, "The Whirlpool algorithm by Tim" was pretty convincing attribution. :-)
I'd need to read up on that algorithm a bit before I have an opinion on whether length-extension attacks are not an issue with it (which is often particularly nasty when the message repeats or is cyclical). Most hashes fare better by prepending a nonce as salt than they do by padding or repeating.
