'''Steganography''' is a science that pertains to the art of concealing data in a communication in such a way that only the sender and receiver know of its existance and method of access. The platform used for transmission can be anything from a paper document to a digital file. Additionally, it is more common than not to [[encrypt]] the hidden data whenever possible such as with digital files or images.

Strings is a program that prints out any ASCII strings in the input file. It is often used to gather information on unknown programs. By reading the messages displayed to the user, the examiner can often get a feel for what the program is supposed to be doing.
