The trouble with quotes on the Internet is that it's difficult to determine whether or not they're real.

In this section, we take a brief look at three instances where classic ciphers played a role in historical events. First, we look at a weak cipher that was used during the controversial U.S. presidential election of 1876. Then we consider the Zimmermann Telegram, which played a pivotal role in World War I. The Zimmermann Telegram was encrypted with a classic codebook cipher. Finally, we discuss the VENONA messages, where Soviet spies in the United States used one‐time pad encryption. This system was used over a long period of time, but most notably for atomic espionage in the 1940s.
