Software


The software we use is not available via download. If you want to decipher the messages by your own, use this great ENIGMA simulator and the keys we found. You can also use CrypTool 2.

Michael´s software to cryptanalyze the Enigma machine code:

CPU Load (Example) Intel Core 2 Quad Q6600:

- The TBreaker software is very resource intensive
- CPU Load 4 x 100% (24/7)
- Temperature ~ 70 Centigrade
- Costs (example - 1 Windows PC): 15 day(s) x 24 h/day x 0,2 kW x 0,30 €/kWh = 21,60 Euro !
