  Substitution Cipher: For the substitution cipher create two copies of a key where each letter in the alphabet is replaced by a different random letter.This works in the same way as the Cesarian Cipher however instead of having each letter shifted a uniform number of spaces, it is shifted a random number of spaces.This code is much more secure then the Cesarian Cipher.
