Here you can download the current versions of JCrypTool. 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. Installation instructions can be found here.
All components contained in the release version have been extensively tested.

Important notices for macOS users only
2) JCrypTool currently does not sign its weekly releases with a key that is known to Apple. As a consequence, the application may be flagged as not trustworthy. To run this release under macOS, do:
- Dowload the JCrypTool and extract the .tar.gz file by double clicking it.
- In the download directory, run the following command in the terminal:
sudo xattr -r -d com.apple.quarantine ~/Downloads/jcryptool.app
(assuming you extracted JCrypTool directly in the folder "Downloads"; otherwise, adapt the command accordingly. The `.app` file ending should be kept.)
- Start the extracted app. The previous steps only have to be done this once — the next time they are not necessary.
Steps for unpacking and executing the application under Windows
1) Download JCrypTool. Choose the file which includes "Windows" in the name. It comes in the form of a ZIP archive.
2) Extract the ZIP archive. A walk-through can be found here.
3) The extracted archive contains a folder named "jcryptool" (commonly in a folder named after the extracted ZIP file). In it, you find the executable file "JCrypTool.exe". You can start it now by double-clicking it.
Windows may ask you to give the application permission to access the network at some point. This is necessary for the help system to work.
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.
