WebFor digraph ciphers (Playfair, Bifid, Four-square, etc), the step size should be 2 and offset 0. For the Trifid cipher, the step size should be 3 and offset 0. Even for single-letter monoalphabetic substitution ciphers, a polygram analysis can be useful to detect common trigrams (like the). Set the step size to 1.

WebThe Mixed Alphabet Cipher is another example of a Monoalphabetic Substitution Cipher, and the way it works is exactly the same as with those already encountered, except in one way. The difference, once again, is how we create the ciphertext alphabet. Unlike all the other ciphers we have seen so far (Atbash, Pigpen, Morse, Shift and Affine), the ...

WebA directed graph (or just "digraph") is a pair (V, E) of a finite set V of vertices and a finite set E of directed edges (or just "edges"). The set of edges E is a subset of V × V (the Cartesian product of V with itself). In this module, V is allowed to be empty. The so obtained unique digraph is called the empty digraph.
