Binary code cipher developed by the English philosopher Francis Bacon (1561-1626) in the 1605. It employed the letters A and B, equivalent to the 0 and 1 of modern codes, to represent the 24 letter alphabet of the time in five letter groups. Bacon's cipher or the Baconian cipher was created as a method of hiding one message within another. It is not a true cipher, but just a way to conceal secret text within plain sight. The way it originally worked is that the writer would use two different typefaces. One would be the A typeface and the other would be B. The message would be written with the two fonts intermingled, thus hiding the message within a perfectly normal text.
