Description

A Route Cipher is a type of transposition cipher where you write the message into a grid box and read the letters in a certain route. This cipher was used by the Union forces during the Civil War. However, they took care to use it in a way that moved entire words around. In addition, sometimes the would encode a word or add null words to protect their message.

In order to create a route cipher, the dimensions of the put the plaintext in and decide what route you want it to follow. Once that is decided, the ciphertext becomes the letters in the order of the route. Therefore, decrypting a message requires the grid dimensions and route path as keys.
