steghide

Steghide is a steganography program that is able to hide data in various kinds of image and audio files. The color-frequencies (for image files) or sample-frequencies (for audio files) 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.

    Release Notes: This release features a new algorithm that makes steghide undetectable by color-frequency based statistical tests. Other (smaller) changes have been made, such as support for all types of JPEG files, the ability to compress the data before embedding, and a new "info" command to get information about the format and capacity of a cover or stego file. Translations into Spanish and Romanian have also been added.
