Being already an established method for nondestructive examination of cultural heritage objects from a conservational perspective, computed tomography is getting more and more popular for answering historical questions. As part of the three-year project 3D-Cipher, the technology will be applied to scan and digitize 61 historical cipher machines ranging from the late 19 th century to the 1990s.

The aim of this contribution is to introduce the museum's collection as well as the project's idea and relevance to cryptologic researchers. Since 3D scans are able to provide non-destructive insights into our rare exhibits, we can thus hopefully contribute by making our devices available to scientists.
