Thanks for writing something like this as a free tool, AND open source. I could see this being useful for stuff like testing customers' hashes. (Though I'm personally partial to command line utilities.) As a feature suggestion, it might be nice to be able to paste a list of hashes.

I'd say it's probably a very useful tool for the average user to test his or her own hashes, without any specialized knowledge.

Being open source is especially important, since if I did use this tool on a client's data, I'd want to audit the code first. So kudos for making a *proper* security product that I can verify if I want to! That's how it's done.
