WebThe structure of the D'Agapeyeff Cipher has similarities to the Polybius square, which the author used as examples in his book. He explicitly solves an example of a Polybius square based cipher from a friend in his cryptanalysis section of the book. This worked example consisted of 178 characters: WebAnother Greek, Polybius (c. 200–118 bc), devised a means of encoding letters into pairs of symbols by a device called the Polybius checkerboard, which is a true biliteral substitution and presages many elements of later cryptographic systems. Similar examples of primitive substitution or transposition ciphers abound in the history of other ... WebThe Bifid cipher was invented by the French amateur cryptographer Félix Delastelle around 1901.
