Hi all
I am releasing under the GPL a Java based Tor research framework that I have developed. ÂThe goal of the framework is to provide a simple and easy to read/modify implementation of the protocol that allows you to do things wrong. ÂThis enables researchers to try things out without trying to battle with the full tor client source or with a client that tries to help you (e.g. by proactively building circuits) - this one does as its told and no more.
At present, it is a fully functional client with a number of examples for hidden services and SOCKS. ÂYou can build arbitrary circuits, build streams, send junk cells, etc. Â
I want to build up the examples over the coming months to include sample attacks on tor (e.g. traffic pattern generators/detectors). ÂI also want to build out the documentation to reduce the barrier to entry for researchers as much as possible.
I hope it will be useful to someone - patches/pull requests always welcome!
