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.

*Information on Cisco Webex Meeting: You are encouraged to allow the Webex Meeting application software to be installed on your computing device. Industry research suggests that security and privacy concerns are minimal. Your favourite browser can also be used, with some reduced functionality and performance. More information about Webex is available here. It is suggested that new participants become familiar with this information in order to make the experience as easy and pleasurable as possible.
