This class can be used to hide encrypted data in images using steganography which is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message.
It reads a given image in GIF, JPEG or PNG formats, encrypts data supplied by the user (a message, a file, a collection of both) and hides the encrypted data in the image by making subtle colour changes to certain pixels to store the data in the image symbolically. The resulting image is generated in PNG format (because PNG is lossless).
The advantage of steganography over cryptography alone is that messages do not attract attention to themselves, to messengers, or to recipients. An unhidden coded message, no matter how unbreakable it is, will arouse suspicion and may in itself be incriminating, as in some countries encryption is illegal.

From the developer who brought you tinyMuw CMS comes the tinyMuw Password Generator! Just like the CMS, this utility was fully developed in a combat theater (specifically Baghdad, Iraq by an American Infantryman). This script comes with powerful default character sets and standardized bit lengths, but enables the user to easily create their own character set and specify any password length they wish, allowing for the greatest variety of passwords possible! For the more savvy computer users, the generator itself is small, compact, portable, allowing you to "plug and play" the modular function into your own scripts with ease.
