Developers: Please create a new account on GitHub like described in the Getting started as a JCrypTool developer guide and email me your new username. I recommend starting with a new workspace.
Subversion access on SourceForge will be disabled immediately, you won't be able to check in changes any more. Read access will remain possible. Pending changes in your local workspace must be migrated manually (either copy and paste or via patch set) to the new Git repository.
Keep in mind that the Plug-in project named plugin on SourceForge is now named crypto.
