The National Cryptologic Museum, operated by the National Security Agency (NSA), highlights many historically significant events, devices, and people in the world of cryptology. This Web site gives brief descriptions of many exhibits showcased at the museum. Some of the most intriguing exhibits include the Civil War, the "Big" Machines, the Codetalkers, the VENONA Project, and the Hall of Honor. There is also a good deal of information about cryptology used to enforce (and violate) prohibition, otherwise known as the Rum War. Aside from the exhibits section, a separate area devoted to NSA's cryptologic history has several interesting features. These range in topic from how slaves escaped to freedom in the mid-1800's to archives from the Cuban Missile Crisis.
