JCrypTool cryptography e-learning platform

If you have ever read about cryptography, history, classical ciphers and even more advanced and modern concepts you probably wanted to experiment and play the codebreaker game. Well here is another cool Eclipse RCP application, it is called "platform for e-learning" Eclipse RCP is a good platform to create platforms to create very easy to extend applications based on a really advanced and tested plug-in mechanism.
From their site JCrypTool is the upcoming cryptography e-learning platform. Developed as an Eclipse Rich Client Platform (RCP) based open source project, it enables students and teachers, developers and others interested in cryptography to apply and analyze cryptographic mechanisms in a modern and easy-to-use application. Its aim is to create a new form of e-learning, by not only encouraging users to learn all about cryptography and to use it, but also to develop their own cryptographic plug-ins and extend the JCrypTool platform in various ways. JCrypTool already supports users in experimenting with various cryptographic mechanisms such as classic, symmetric and asymmetric encryption, hash values, cryptographic analysis and games.
I'll try to write a plug-in for this application and post the results here.
