The JCrypTool Crypto project contains all crypto plug-ins for JCrypTool: Algorithms (classic, modern and XML Security), Analysis, Games and Visualizations. Basic crypto features are included in this repository too.
These projects require the plug-ins from the JCrypTool Core repository to compile and to run.
Have a look at our wiki for more information on how to get you started as a JCrypTool developer. Feel free to ask any question you might have in our developers group.
JCrypTool downloads are available as weekly builds (unstable) and as release builds (stable).
General information on the CrypTool and JCrypTool projects is available in the CrypTool portal.
