steghide

A steganography program

Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests. Features of steghide include compression and encryption of embedded data, embedding of a checksum to verify the integrity of the extracted data and support for jpeg, bmp, wav and au files.
