Following the evidence of the 'DE' language option and the identification of the German CrypTool project, another key institution involved in its development is the University of Duisburg-Essen. This university is frequently cited as a major contributor to the project, making it a highly plausible secondary candidate for the real-world location of the team behind the software shown.

The screenshot's 'DE' language option confirms a German connection. The subject is a technical web application related to cryptography. As Germany's capital and largest technology hub, Berlin is a plausible, though non-specific, location for the developers or hosting infrastructure of such a project. This is a more general guess compared to the specific universities associated with the CrypTool project.
