Steganosaurus (stego) by John Walker is a UNIX program that transforms any binary file into nonsense text based on a dictionary either given explicitly or built on the fly from a source document. The output of stego is nonsense, but statistically resembles text in the language of the dictionary supplied. Although a human reader will instantly recognize it as gibberish, statistical sampling employed by eavesdroppers to detect encrypted messages may consider it to be unremarkable.
