The first working release of Monkeysign is now available through the git repository. After more than two years of intermittent development, we now have a quite user-friendly tool to easily and securely exchange OpenPGP key certifications. See the website for more information.
The code is still "beta" in that it has been tested only by the author, so extra testing and feedback will be welcome so we can make a 1.0 release.
The code is only available through git right now, we are working on providing a Debian package while the code matures. Use the following to get the code:
git clone git://git.monkeysphere.info/monkeysign
