JCrypTool is the Java and Eclipse Rich Client Platform based cryptography e-learning platform. Developed as an open-source project, 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, visualizations and crypto games.
JCrypTool is bundled with the advanced cryptographic libraries BouncyCastle and FlexiProvider; other libraries can be easily added to the project. FlexiProvider is the initial default provider, but users can freely change to a different default provider. A fall-through functionality searches top-down for an implementation of any given cryptographic algorithm so that even a specialized provider with only a small subset of algorithms can be selected as the default.
Visit the JCrypTool Core Project on GitHub for the source code (available via Git), developer documentation, wiki and further information about the project. For our cryptographic plug-ins visit the JCrypTool Crypto Project. Our wiki is a good place for new developers to get started and to find additional information, such as our release schedule and a huge list of project ideas.
