The original concept that spawned this can be found at http://www.nth-dimension.org.uk/utils/ghash.php. I wrote this up to see if it would actually work... And it would be more convenient than having to download a 50+ GB rainbow table from here (or here).
Ideally, you'd be using this to recover a forgotten password. But it could also be used for less ethical/illegal purposes. Knowledge is power. With power comes responsibility. Use this tool wisely. What you do with knowledge is up to you; I take no responsibility for your actions.
The list of characters that I support:
(configuration 6 of the antsight.com rainbowcrack tables)
Here's the hash for password: http://darwin.servehttp.com/cgi-bin/hash.pl?show=md5&word=password (=> 5f4dcc3b5aa765d61d8327deb882cf99 =^.^=)
Now here's the question: How long will it take Google before they crawl the entire thing? :D Currently, it's set to 16 max characters, although I probably should have set it to 8. Here's to hoping Google doesn't crawl depth-first...
Other MD5 tools:

 Here's the source code, for anyone who might be interested. It's licensed under GPL, although quote honestly, I don't think I fully grasp the concept of GPL. They need an easier-to-understand license XP Or provide a "common language" equivalent, similar to the nice Creative Commons license. But if you decide to run the code elsewhere, do drop me a line - I'd be interested.
[edit 2] Looks like here's another one with a similar idea. Except they hash all of the options and don't cover as many letters as I do. I wonder if it's more effective...?
Ah, it looks like while Google has crawled them, there's a limit to how much Google will crawl. Like the reverse.me.uk site only retrieves 49 search results. While a site like apple.com will retrieve 45K results.
Why is that? Does Google check for unique looking pages? o.O I wish I knew what algorithm Google was using, and how to maybe get past that. Maybe I should add random password generators at the bottom of the script, so Google will randomly jump to deeper hashes? Maybe? o.O
[edit 3] And here's another one. Again, Google doesn't find anything after the first few letters. Interesting..
