Code Creation Manual: The Cipher Maker allows you to create Cesarian Ciphers, the type of cipher used by Cesear to encode messages. Cesarian Ciphers use a set shift to encode messages. For example if you were to use a +3 shift /"abc/" would become /"cde/".The Code Breaker is a program designed to break Cesarian Ciphers. As you can tell by the ease of cracking Cesarian Ciphers with the Code Breaker Cesarian Ciphers are not very secure.This is because there are only 26 possible Cesarian Ciphers (26 letters in the alphabet). Below are several much more secure encoding techniques are described for your use.

Book Cipher: The book cipher requires that both the sender and the recipient have acess to the exact same book or newspaper. The more obscure the book the more secure the code.For the Book Cipher you give the position of each word in your message, and to decode it the recipient finds each word in the predetermined book. The easiest way to describe positions in books is page number/line number/word number. So for example 258/5/4 would mean the 4th word on the fifth line of the 258th page of the book.

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.
