Did you know?

CrypTool 2 provides visualization as well as workflow controls to enable intuitive manipulation and interaction of the cryptographic primitives.

This page is an archive of all current builds of CrypTool 2.
The builds run on 64 Bit Windows. Please note that you need the Microsoft .NET Framework 4.7.2 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 their own 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.
