The JCrypTool Incubator repository contains all crypto plug-ins for JCrypTool that are not yet ready to ship in our stable release. Some of these plug-ins might have a referenced idea in our wiki.
These projects require the plug-ins from the JCrypTool Core repository to compile and to run and may require additional plug-ins from the JCrypTool Crypto repository.
Have a look at our wiki for more information, especially the Getting started as a JCrypTool Developer page. Feel free to ask any question you might have in our gitter chat.
JCrypTool downloads are available as weekly builds (unstable, built automatically based on the develop branch) and as release builds (stable).
General information on the CrypTool and JCrypTool projects is available in the CrypTool portal.
