The Zodiac Killer Cipher Generator - an online tool for creating homophonic substitution ciphers similar to those created by the Zodiac Killer. To decode ciphertext letters, one should use a reverse substitution and change the letters back. This is termed a substitution alphabet. Example. The simple substitution cipher is a cipher that has been in use for many hundreds of years (an excellent history is given in Simon Singhs 'the Code Book'). Substitution ciphers can be compared with transposition ciphers. This however expanded rapidly, to include many common words, phrases and places. Where word divisions are kept the American Cryptogram Association (ACA) refers to the monoalphabet substitution cipher as the "Aristocrat" cipher. When plain text is encrypted it becomes unreadable and is known as ciphertext.

It basically consists of substituting every plaintext character for a different ciphertext character. The cipher alphabet may be shifted or reversed (creating the Caesar and Atbash ciphers, respectively) or scrambled in a more complex fashion, in which case it is called a mixed alphabet or deranged alphabet. Use an online substitution generator to save paper. It is also useful for manual cryptanalysis of a substitution cipher - when you have a message written in the English alphabet partially decrypted with an automatic tool and want to tweak the key. In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with ciphertext, according to a fixed system; the "units" may be single letters, pairs of letters, triplets of letters, mixtures of the above, and so forth.
