Hand Ciphers
Simple manual methods for encryption

One of the most basic methods for exchanging encrypted messages is a substitution cipher. In its simplest form it uses a shifted alphabet. This is often called a Caesar Cipher, as it was used by Julius Caesar for communication with his generals. Hand methods have since been used in many different forms with varying success. This section of the website deals with some of these methods.
