PHP hash tool

I often find myself in the need to create a md5/sha256 hash for various reasons. Most of the time I use Google to find a javascript tool that i can use. This is fine, but a bit inconvenient, so i decided to create a little script that can create all sorts of hashes from a string.

The script is capable to generate all hash types supported by the hash extension.

You can test the script here, and view the source code here.
