Bit shifting blind injection : Simplified!

I've recently been investigating Blind SQL injection, and have become quite fond of the practice. I stumbled upon a new technique documented by (see here that used Bit shifting to guess the bits that make up the chars of the information you are trying to extract from the database.

I then came up with a modification to the method to try and make it simpler and hopefully allow the development of an even faster method (which im still working on) . My method uses the XOR bitwise operation to simplify the output and operation of the attack.

Thought relatively simple methods, they still require a comfortable understanding of the binary number system and can be frustrating to use. The method I'm about to show you can be performed with minimal understanding of the binary number system. This is because you don't need to convert in and out of binary while performing the attack.
