Introductory Synopsis

Abstract

We must distinguish between cryptography (Greek kryptos hidden) and steganography (Greek steganos, covered). The term cryptographia, to mean secrecy in writing, was used in 1641 by John Wilkins, a founder with John Wallis of the Royal Society; the word ‘cryptography’ was coined in 1658 by Thomas Browne, famous English physician and writer. It is the aim of cryptography to render a message incomprehensible to an unauthorized reader: ars occulte scribendi. One speaks of overt secret writing: overt in the sense of being obviously recognizable as secret writing.
