Project Ideas
JCrypTool (JCT) is the most wide-spread, free, and platform-independent e-learning program for cryptography and cryptanalysis. It runs under Windows, Mac OS X, and Linux. JCT is supported and used by universities and schools all over the world.
The following two lists contain smaller and larger projects for the JCrypTool platform with open tasks. The first list contains crypto related project ideas (all items starting with a C in their ID), the second list contains non-crypto related project ideas (all items starting with a N in their ID). Each project is either in status idea, active, or finished.
-
In case you are interested in an active project, do not hesitate to contact us; it might be possible to complete this project together with another team member already working on it and bring in your own thoughts.
-
Projects with status idea are waiting for any interested developer or developers. Please contact us right away.
-
Finished projects are moved to our project archive page. But even a finished project may be extended with new features in a new project. Simply contact us.
Nothing of interest available for you, but you do like the JCrypTool project and you want to be a part of it? Feel free to contact us: We might have some more ideas at an early stage that are not quite ready for our lists here; and of course we are open to any further ideas you might have!
If you have questions or need more information on a possible development task, don't hesitate to post a question in our developers group.
Please contact Dominik Schadow or Bernhard Esslinger in case you want to work on a project listed on this page. We will update its status and add your name to the selected task. At the same time, we will create a new entry in one of our issue trackers (core, crypto, or incubator), in which you track your progress. You also can come up with your own suggestion for a project.
The specifications given for each task are generally not very strict and not very extensive. This is on purpose. The main intention of these lists is to give you some project ideas. You can be creative and develop a solution with fancy cryptographic animations, easy to use wizards, and lots of support for the user. Everything is up to you. The only important thing we strongly ask for is full Eclipse 4.x compatibility, which means the usage of Eclipse functionality like SWT and JFace, but no deprecated methods.
Most projects listed below require at least some Eclipse plug-in and RCP development knowledge as well as cryptographic knowledge. This knowledge is of course not required from the beginning, you can learn this while developing your project! Required from the beginning is Java knowledge and some practical experience developing in this language and using the GitHub repository. What we expect is curiosity and a lot of interest in learning and experimenting with new technologies.
Normally, all JCrypTool plug-ins are available in English and German. In case you don't speak any German we will find someone else to translate your plug-in. This is why German is an optional requirement most of the time in the following two lists.
More information is available from the JCrypTool community which you may contact in the JCrypTool Developers Group or in our IRC channel #jcryptool on freenode. Another good opportunity to get in touch is the Gitter chat room.

Currently the crypto service providers FlexiProvider (FP) and Bouncy Castle (BC) are used in JCT. Only for FP versions, JCT has the feature to automatically adopt its offered functions when updating the shipped FlexiProvider plug-in. The reason is, that only FP describes its functions in special metadata which is extracted into an XML file which is used at runtime by JCT. This keeps the JCrypTool program up-to-date dynamically when a new FP library is released and the corresponding JCrypTool updated with it (this means that JCT will adapt its menus and the dynamic wizards in the function-centric view to always match a new FP version).
An important task for JCT and for BC will be to maintain such metadata in BC and implement an admin tool for BC, as BC will be the default crypto provider for JCT in the future. The admin tool must be an JCrypTool RCP plug-in which is not intended to be shipped to the end-user, it is an internal plug-in for the JCT developers.
After this works, JCT is planned to become THE GUI of choice for the BC libary.

In the article "The Design and Use of Interactive Visualization Applets for Teaching Ciphers" by Dino Schweitzer and Leemon Baird, presented at the 7th IEEE Workshop on Information Assurance, 2006 the authors evaluate several crypto tools. Despite the relative leading position of CrypTool ("Of the cryptography tools reviewed, perhaps the most comprehensive interactive one is the freeware program CrypTool.") there are several requirements they suggest to make this tool fitting better for teachers and lecturers. The aim is that the visualizations had to be quickly understood in a classroom setting.

JCrypTool already contains most of the modern, state-of-the-art crypto algorithms. In the area of historical ciphers, many are missing.

There is a broad set of algorithms to factorize numbers into their primes. These tools like brute-force, Pollard, Lenstra, Quadratic Sieve, and General Number Field Sieve are appropriate for different numbers and different resources. The aim is to bring them together and reuse the best tools there (like msieve), however in addition improve the decision which algorithm to choose, avoid wrong results by currently used script. There are some existing implementations which could be very helpful for a head start, like Bernstein's FactHacks -- RSA factorization in the real world at 29C3.

This project aims at the implementation of hash-based digital signature schemes including their visualization. The Merkle signature scheme (MSS) e.g. can be instantiated with every cryptographic hash function. Unlike, for example, RSA or ECDSA, it is secure even in the presence of quantum computers.
In a series of bachelor projects, the schemes WOTS, MSS, XMSS, XMSS_MT, and Sphincs have been implemented in JCT. Further schemes are welcome.

Develop a basic and easy to use XML editor as Eclipse plug-in working in a RCP. Basic operations include syntax completion, syntax coloring, auto-closing of start tags, and well-formedness checks with error markers. Consider using the Eclipse XML editor sample template as a start. However, the XML editor must work inside the JCrypTool RCP with limited plug-in dependencies (e.g. there are no IDE related plug-ins available yet).
An alternative would be the integration of an existing open source XML editor given that there is license compatibility with JCrypTool (EPL).
