Changing the JCrypTool Runtime Language

In Eclipse, JCrypTool is automatically launched in the language defined in your operating systems regional settings. We recommend creating specialized runtime menu entries for both supported languages, English and German.

Doing this is easy: launch JCrypTool as described in the Getting started as a JCrypTool Developer guide once. This creates the initial run menu entry.

Now open the Run Configurations dialog and select the created JCrypTool entry. Change the name to e.g. JCrypTool (English) and switch to the Arguments tab. Watch out for the -nl attribute in the Program arguments textbox. Change this to -nl en and click the Apply button. Now click on the Duplicate icon in the upper left to duplicate the run menu entry. Name this entry JCrypTool (German) and switch again to the Arguments tab. Change the -nl attribute to -nl de and click Apply again.

That's it, just close the run configurations dialog and select the appropriate entry to run JCrypTool in the desired language.
