Chaocipher Clearing House

Chaocipher Clearing House

Moshe Rubin's Web site serves as an online clearing house of information about the Chaocipher. On the site he includes fact, fiction, and folklore about John Byrne's legendary invention from 1918. Unsolved for so many years, it finally took 57 years (from the publication of Byrne's "Silent Years" in 1953 until June 2010) for the cipher algorithm to be revealed.

Included here is link to a short chaocipher animation on YouTube, (pictured above) put together by Nick Pelling.

In Pelling's 3 July 2010 post about the Chaocipher on his site, Ciphermysteries.com, he describes the Chaocipher as follows: “The Chaocipher” is a devious cipher system invented in 1918 by John F. Byrne: allegedly, it was so complex that nobody could crack his challenge ciphertexts (even with the plaintext to refer to!), yet was so simple that its mechanism was claimed to comprise only two rotating disks small enough to fit in a cigar box, and could be operated by a ten-year-old (admittedly a diligent, determined and well-practised one) to encipher and decipher texts.

About Us

The NCMF directly supports the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. We think you will agree it is truly a "museum like no other."

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCMF acquires the best artifacts for the NCM and supports new educational and interactive exhibits.

The NCMF provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and innovation through valued awards, and hosts educational, cryptology-related exhibits at various community events.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCMF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCMF and NCM share a joint three-fold mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
