In cryptography, the ADFGVX cipher was a field cipher used by the German Army on the Western Front during World War I. ADFGVX was in fact an extension of an earlier cipher called ADFGX.
Invented by Colonel Fritz Nebel and introduced in March 1918, the cipher was a fractionating transposition cipher which combined a modified Polybius square with a single columnar transposition.

... Although the ADFGVX is moot technologically and cryptographically, the cipher system can be used as a predecessor for a mechanical cipher machine or a cipher implemented in software ... ADFGVX can still remain useful if different substitution tableaus and column substitution tables are chosen at the same time the mechanical cipher keys are changed ...
Famous quotes containing the word cipher:
“It is not an arbitrary decree of God, but in the nature of man, that a veil shuts down on the facts of to-morrow; for the soul will not have us read any other cipher than that of cause and effect. By this veil, which curtains events, it instructs the children of men to live in to-day.”
—Ralph Waldo Emerson (18031882)
