The use of cryptography began thousands of years ago as a way to protect secrets using codes and ciphers. However, it wasn’t until the 20th century that mechanical systems such as the Enigma rotor machine made encryption an efficient and effective way to protect information. Today, encryption methods used to make ciphers has become more complex and even harder to break. This Activity Kit gives students an introduction into cryptography and includes hands-on exercises designed to teach students how to encrypt and decrypt messages using ciphers.

This activity kit will require the following resources:
