Steganography! A Web-based GUI for Steghide
January 9th, 2009 Joshua Moyers
I got bored the other day and figured I’d go about creating an easy-to-use GUI for steghide. My original idea was to create a quick little batch file to make the entire thing an ease, taking care of arguments -n- whatnot for those who aren’t to good with a command prompt or shell environment.
After realizing how much working with Windows batch files sucked, I decided to see what I could do using PHP and its exec() and system() functions. Using these I have created a nice little GUI that allows users to upload an image, type in text and a password and receive a finished image with text hidden within it. It currently only supports JPEG and BMP files, but I could have it work with WAV and AU files as well. I just figured I’d keep things simple.
The script also allows you to extract the text from a steg’d image provided you have the password which was used to embed it. Simply upload the file, input the password and click a button! The text will be displayed and you’ll have your hidden message!
All credit for the program Steghide goes to the original developer. I just used PHP to run the program on my server and return the results. For more information on Steghide feel free to visit its SourceForge page my clicking here.
