Seeing this website here made me chuckle. Mr. Hörenberg was a teacher at my school. He once held a "guest lecture" within my CS class where he told us about his hobby of breaking engima codes and how his software worked. He once used multiple of our schools computer rooms during summer break to run his software. Luckily for him, we had CAD classes and therefore appropriate workstations. Some of it is explained here: https://enigma.hoerenberg.com/index.php?cat=Breaking%20the%20M4&page=How%20to%20break%20the%20ENIGMA%20M4 https://enigma.hoerenberg.com/index.php?cat=Breaking%20the%2... (A funny sidenote was that he wasn't and admin in our school and had now way of deactivating the screensaver then to walk from desk to desk every 14 minutes and move the mouse.)
