Land der Ideen - Statements
“I really like CrypTool. Despite the extensive possibilities, it is not too complex for the user, with further simplification due to the synergies between the menus and the extensive documentation. Thanks to the defaults, it is possible to quickly get started with trying out individual modules, even if one might not fully understand the exercises in the beginning. But this piques the interest to dig deeper into the possibilities.”
