I've been working on a project called QuantumGate for at least the last 3 years and the project is making some slow and steady progress. I'm looking for cryptographers and hackers who would like to take a look at it and give feedback, and especially try to break it.

The project and C++ source code (MIT licensed) is on GitHub (https://github.com/kareldonk/QuantumGate/) and the wiki there has a lot of detailed information on it including examples and tutorials.

I published the first alpha release yesterday that includes pre-compiled binaries for those who want to quickly try it out without having to build everything from source code (with all the dependencies etc.). There are some test applications included that you can try that I mainly use for testing purposes.

Thanks.
