Jsteg Shell

Jsteg Shell reads almost any lossless picture format and saves the output file as a JPEG. An important note from the authors is this program does not read JPEGs; it only exports the final product in JPEG format. This has several benefits. First, saving a stego-image as a JPEG makes the file that much more unnoticeable because it is the de facto standard for the Internet and newsgroups. Second, steganographic information is more difficult to detect with the naked eye in a JPEG image than it is in other formats.
