Did you know

It has always been essential for every version of CrypTool to come with thorough documentation about its features. Whenever the user presses F1 on their keyboard, corresponding information about the feature currently selected appears.

This page is an archive of all current builds of CrypTool 2.
The builds run on 32 and 64 Bit Windows. Please note that you need the Microsoft .NET Framework 4.7.1 to run CrypTool 2.
No admin rights are needed for the installation.
Each build is available as an .exe installer and as a compressed zip archive. Both have an online update mechanism. The .exe installer supports registration of start menu entry, desktop link and explorer file type, but does not support more than one .exe installation. If in doubt, use the .exe installer.
