At one point, it was required to obfuscate the data in the querystring. Hiding it (i.e. using different methods to pass data to a page) was not an option, as the pages needed to be able to stand alone (e.g. give a fully functional link for an offer banner). So I built an obfuscation scheme.

In my two previous posts (
here and
here), I showed how to create two of the components needed for my
steganography project. This post is about the part where we manipulate the least significant bits of the RGB components of a pixel.

I've shown the inner workings of the first essential component for my
steganography project in a previous post
here. The second essential part is a pseudo-random number generator (PRNG) that's seedable.

In order to develop the steganography project
I described earlier, I'll need a class that can convert any given text to a Brainfuck program, and also to "run" such a program to reproduce the original text. It turns out, this is not that difficult.
