Gifsteg - simple steganography (C, GPL)

This program can be used to hide files within pictures for distribution (steganography). There are much better ways of hiding information, but there's something pretty cool about hiding the information in plain sight. You'll need make & gcc to compile the program before use. It has been tested on Linux and Windows (Cygwin).

Example usage

To hide a tree in a forest (har har):

./gifsteg.exe -e forest.gif tree.jpg -mask 00000001 -pad noise
+ -->

To extract the hidden image

./gifsteg.exe -d forest.gif
