Overview

Image steganography is the process of hiding information within an image. This program is utilized to hide a text based message within an image.

Why

When I first (seriously) got into python my freshman year, one of the first projects I made was a hacky image steganography program. I recently went through my school HDD, and got the idea to remake it for fun. So low and behold; here is my remade image steganography program :)

How-To

Just load up ImageSteganography.py and execute it.

• Place whatever images you want to encrypt a message into, inside the /encrypt sub directory.
• Place whatever images you want to decrypt a message into, inside the /decrypt sub directory.
• Any images encrypted with the program will be replicated and saved into the /export sub directory.

The program will work with multiple images, so if you place multiple images within a sub directory, it'll work with all of them. It also recognizes the file extension, so if you have a bunch of text files within a sub directory it'll just ignore them.

Limitations

• This progam was developed in Python 3.0, although it should work with Python 2.7, but I haven't gotten around to testing it yet.
• This program will ONLY work with PNG images. JPEG images have a specific compression issue that screws with the encryption algorithim.
• You can only encrypt a specific amount of characters within an image. The exact amount is based off the size of the image (one pixel is dedicated to each character).
