Mad ideas always score, and this one is almost finished! The basic idea of this project is to use the CPU of our visitors for cracking passwords, encrypted in md5 or SHA1 or something like that.

The code I have so far is quite simple, it works like this:

Step 1: generate a MySQL table filled with the so called "ranges" or "blocks", a block is a part of the amount of hashes you want to generate for cracking your hash. For example, the blocksize I'm currently using is 50. So if I want to generate a million hashes, I'd create 20,000 blocks.

Step 2: create a server file for the AJAX function in the Javascript cracker. The server file is written in PHP and returns a random, uncompleted range from the database.

Step 3: the moment a user visits a page, the AJAX function retrieves a random block from the server and starts cracking it (small blocksize so the cracking only takes a few miliseconds). If the block is finished, it tells the server. If the hash is cracked, it also tells the server. The server checks this (no invalid input by evil users, kthxbye) and if this is correct, removes all remaining blocks.

The main issue here is that you need a huge website to get really good speeds. RandomBase receives around 3 hits / second, which would mean only 150 hashes / second.
