SHA1 Javascript Tool

Occasionally, I need a SHA1 hash of something, and I’m not in a convenient place to get one. For instance, it is hard to open up a terminal to run sha1sum on public internet kiosks. It’s also obnoxious to have to SSH anywhere from my phone to get access to a SHA1 algorithm.

So, I took Paul Johnston’s Javascript implementation and made a simple webform. Trivial, I know. But I took out unnecessary HMAC calculation code, so it should be relatively easy to examine the source if you’re worried about using something secure. The webdesign is, hah, optimized for mobile devices.
