What is ICCH?

The International Conference on Cryptologic History (ICCH) is a forum for the discussion of cryptologic history. Established in 2004 as 'Crypto Collectors', the group includes members located in many countries around the world. ICCH holds events both online and in-person, and also has an email list for general discussion.

Live presentations are held online every fortnight, covering topics including cipher machines/devices, as well as codes and codebreaking from the world's leading experts on cryptologic history. These are held via the video conferencing program Webex Meeting*. Once a year, ICCH meets at the Friedrichshafen HAM Radio Festival, in Germany for the annual Enigma Forum and flea market. Find out more about the Friedrichshafen event here.

FRIEDRICHSHAFEN 2022

The annual ICCH Enigma Forum and Flea Market at the Friedrichshafen HAM Radio Fest 2022 will be held on June 24 -- 26, 2022.

Although this meet is not specifically listed as a crypto-collectors meet, it has gradually become the major annual European selling and meeting place of people with crypto interests and you will find constant and fascinating action at our tables and others throughout the duration of the show. In 2019 over $200,000 in crypto-machines changed hands and the Forum was very well attended.
