FireSteg
From Just Solve the File Format Problem
FireSteg by Zach Oakes is an open source Java steganography program for hiding data in 24-bit JPEG and PNG images.
The UI worked as a Firefox extension and definitely doesn't work in modern Firefox versions. However, you can run FireSteg.jar from the command line and it should still work.
- Hides multiple files across multiple images
- Remembers the file names of whatever you hide
- Automatically uses the lowest significant bit that space allows
- Encrypts all files and file names with a password before hiding them.
It is based off of Digital Invisible Ink Toolkit
