JCrypTool

JCrypTool is the new cryptography e-learning platform. Developed as an open-source project based on the Eclipse Rich Client Platform (RCP), it enables students, teachers, developers, and anyone else interested in cryptography to apply and analyze cryptographic algorithms in a modern, easy-to-use application.

Its aim is to create a new form of e-learning by not just encouraging users to learn about cryptography and apply the algorithms themselves, but also to develop their own cryptographic plug-ins and extend the JCrypTool platform in new directions. JCrypTool already includes a wealth of cryptographic mechanisms including classic, symmetric, and asymmetric encryption, hash functions, analysis tools, and number games.
