(Steganography is the practice of concealing meaningful information in another bit of data called a covertext. The first steganographic messages were stone tablets with military orders written on them which were then covered with wax on which a different set of instructions had been carved. To get the real message you had to boil the tablet and remove the wax. Steganography is not encryption, but camouflage, and cryptographers look down their noses at it because once you start searching for steganographically transmitted information you will readily find it.
