Discover the science of cryptology! This book is a complete introduction to codes, ciphers and secret messages. You will discover:
- How codes and ciphers work
- How secret messages can be concealed in apparently innocuous messages (steganography)
- How codebreakers and cryptanalysts break codes and ciphers
- Many examples of how codes and ciphers have changed history and continue to shape the world to this day

Enigma (see Chapter 8) was an electromechanical machine that enciphered and deciphered messages. It was used by Germany in the interwar years and during World War II. The general principle of Enigma was that messages would be enciphered by the sender using the machine and then transmitted by Morse code over the radio as encoded ciphertext. The recipient would transcribe the Morse code, and then enter it into their own Enigma machine to decipher the message. The radio signals could of course be intercepted by the German’s enemies, but the Germans (wrongly) believed that their messages were secure, since they did not think that Allied cryptanalysts would be able to break the cipher.
