Welcome to the world of Puzzle hunting! On our fun adventure tours you will need to decode secrets hidden within the historical sites around our cities. Below you will find a sample of ciphers and techniques to help you along your quest.


Elementsofencryption

To encrypt a plaintext message, the sender passes it through an encryption algorithm. The algorithm is a general system for encryption, and needs to be specified exactly by selecting a key. Applying the key and algorithm together to a plaintext generates the encrypted message, or ciphertext.*

*The Code Book, Simon Singh


Here is an example of a simple cipher.

Reverse Alphabet

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A

Using this cipher you would simply replace your original message, letter for letter with the matching substitution of a reverse mirrored alphabet.

So the message…

Ceasar Cipher

Morse Code

Rail Fence

Substitution Cipher

Vigenere Cipher

 You will need to use these, and many more methods on our city wide Puzzlehunt challenges! Although our challenges start out fairly simple be warned, only 50% of those who started the challenge last year were able to finish in the 7 months the season ran. Do you have what it takes?
