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. We do have a permanent collection however, and regularly organize exhibitions and events in co-operation with other museums.

The main goal of the Crypto Museum is to preserve history. This is done by collecting, restoring and describing historical cipher machines, such as the well-known Enigma machine, spy radio sets, intercept receivers and and other spy-related stuff. For a detailed explanation of why we do this, please read our Mission Statement. Some of the items described on this website are part of the collection of the Crypto Museum, but others have only crossed our path at one moment or another. 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. And if you want to make a donation, financial or otherwise, please click here.
