The first "leet" working prototype is available at GitHub, you can download it now and experiment with it, it still has a few bugs which must be ironed out, and it should be simpler than this and more user friendly, but the first building blocks are already put in place.
You can now create a main key, then encrypt any file with the AES cipher then decrypt it, the application might crash, and the README file should be updated soon for software requirements, if it doesn't work for you, you might have to install "pycrypto" and "setuptools" python 3 libraries. But please remember, this is early alpha software. All features aren't implemented yet, and there are still bugs in the code.
For a more complete description of the build instructions, see the appropriate project post under the "Projects" menu item.
