JCrypTool Downloads

There are two versions of JCrypTool, the release version and the weekly build. If you don't know which one to choose, you should prefer the release version. A 64-bit operating system is required for execution. More installation instructions can be found here.

Release Version

All components contained in the release version have been extensively tested. For MacOS, instead of 1.0.9 you will get the current weekly build because in that version, the Java runtime is already bundled.


Weekly Build

If you want to try out newer components, that are not yet included in the release version, you can alternatively download the current "weekly build" of JCrypTool.

Weekly builds are compiled every week based on the most current version of the source code contained in the Git repository. Please be aware that these builds are work in progress, so they may contain experimental features that are not yet fully functional.


More weekly builds can be downloaded from our GitHub project page. They are automatically created every Saturday and are not announced. We appreciate Your feedback about new features or found bugs!
