Steganography is the art and science of hiding information (secret message) within other information (cover-object). This paper explores the fitness of programs as cover-objects. We identify three elements of choice, in which we can encode the secret message. This way, we can on average encode one bit for every 26 bit in the original program. Unfortunately, at this encoding rate, the presence of the message can easily be detected. We can improve the stealth of the message at the cost of the encoding rate. As a result, we obtain a safe encoding rate of 1/89.
