HOWTO: Graph your GPG keyring

We had a keysigning party at work today, and after it finished a few of us were looking for a way to visualize the newly increased signature density. It turns out the best tool for the job is called sig2dot, which is available in the Debian repositories (and as a Perl script on its homepage). […]

For the most part I use email, IMs, and SMS, respectively, for those purposes. Each of those technologies has its own end-to-end encryption protocol.1 Email has the venerable OpenPGP protocol and the GnuPG suite of programs; IM […]
