StegoStick
From Just Solve the File Format Problem
StegoStick by P.V. Uma Mahesh and V. Santhosh Kumar is an open source steganography program that allows the hiding of a file in a BMP, WAV, AVI, or MPEG and the embedding of any file within another.
It has 3 different encoders:
- BMP - uses standard LSB hiding. It will convert JPG or GIF to BMP
- Media (WAV, AVI, MPEG) - semi-generic LSB algorithm. Unfortunately it uses the LSB of every byte, so if a chunk is more than 8 bits (like a 16-bit WAV), changes aren't limited to the LSB, degrading the output
- Other - generic file appending
It requires a password and offers DES, TripleDES, RSA and 'default' encryption
One weakness is that it is possible to determine what filetype was embedded
