Bill cipher tattoo1/1/2024 Until the 1960s, secure cryptography was largely the preserve of governments. Thus the Zimmermann Telegram triggered the United States' entry into World War I and Allies reading of Nazi Germany's ciphers shortened World War II, in some evaluations by as much as two years. The discovery and application, early on, of frequency analysis to the reading of encrypted communications has, on occasion, altered the course of history. The development of cryptography has been paralleled by the development of cryptanalysis - the "breaking" of codes and ciphers. In the early 20th century, the invention of complex mechanical and electromechanical machines, such as the Enigma rotor machine, provided more sophisticated and efficient means of encryption and the subsequent introduction of electronics and computing has allowed elaborate schemes of still greater complexity, most of which are entirely unsuited to pen and paper. Until recent decades, it has been the story of what might be called classical cryptography - that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids.
