National Cryptologic Museum

The National Cryptologic Museum is focused on American cryptologic history that is affiliated with the National Security Agency (NSA). It was the first public museum in the U.S. Intelligence Community and is located close to NSA headquarters at Fort George G. Meade in Maryland.

The museum offers tours that describe Cryptology’s history led by docents who are retired NSA employees.

The museum’s collection contains thousands of artifacts. Initially, it started with the housing of NSA artifacts for employees only. Later the museum developed into a collection of U.S. cryptologic history that became public.

Some artifacts date back to pre-American Revolutionary War times when George Washington integrated military intelligence tactics, including coded messaging, into the Continental Army during the Revolutionary War.

The National Cryptologic Museum collections include:

Early Cryptology – cryptologic history before the formation of NSA
Cold War/Information Age – the early years of NSA, and the rise of the modern age of computers and the development of supercomputers
Information Assurance – the rise of satellite technology, secure voice communications, tamper-evident technologies, and use of biometrics in data protection
Memorial Hall – the NSA Hall of Honor, and exhibits honoring those who lost their lives in cryptologic missions

The library is non-circulating and includes the files of Herbert Yardley, declassified Enigma messages, technical reports, and books, including how to crack the Data Encryption Standard using Deep Crack.

The NSA Hall of Honor is a memorial honoring individuals with distinguished service to American Cryptology. Honored individuals were innovators whose expertise in NSA subjects made significant contributions to American Cryptology.
