Aurora Image Encoder is designed to take a normal 32-bit bitmap image and any other file and merge the two togather into a new bitmap that will look identical to the original bitmap. Later, the encoded data can be extracted from the bitmap in its entirety. The data can also be encrypted first, for added security. The benefit of this encoding is that the hidden data is unlikely to be found simply by the fact that its existance is unknown. Also, if the data is encrypted, there is no way of testing for the existance of such data (even using this program) unless the correct password is provided. Click on the picture at the left to save it.

This program works by first XORing the data by a form of the password in order to encrypt it. The size of the file is added at the begining of its stream. The data is then stored bit by bit into the bitmap. This is done using the lowest order bits of the red, green, and blue bytes of each pixel. Thus the maximum amount of data storable in any bitmap is Width*Height*3 bits or divide by 8 for bytes.
