Crypto Museum
Welcome at the Crypto Museum website. At present we are a virtual museum in The Netherlands, that can only be visited on the internet 24 hours a day. However, we do have a physical collection, and regularly organise exhibitions, events and lectures, in cooperation with other organisations.

The main goal of Crypto Museum is to preserve history. This is done by collecting, restoring and describing historical cipher machines – such as the well-known Enigma machinespy radio sets, intercept receivers and and other spy-related stuff. For a detailed explanation of why we do this, please read our mission statement. Many of the items described on this website are part of the Crypto Museum collection, but some have only crossed our path briefly, or are impossible to obtain. Whenever possible, we have tried to describe the equipment to the best of our abilities.

We are always interested in acquiring new equipment for the museum. If you have any questions or if you have something to offer, please do not hestitate to contact us. Your help is much appreciated. And if you want to make a donation, financial or otherwise, please click here.
