Neil W is something of a guru on the topic of using it, having lurked on the GNUPG mailing list for too long. Enigmail lets you indicate where you've put the public key on the Internet (URI) in the emails. But it is far more useful just to stick the public key on the public key servers. # First configure a keyserver - you want a "subkey safe" (sks) server. $ grep keyserver .gnupg/gpg.conf keyserver random.sks.keyserver.penguin.de # Then find your key ID $ gpg --list-keys Simon Waters | head -1 # Actually you need to read the output but "-1" will do for mine. pub 1024D/8F455606 2002-11-01 # Then send it. $ gpg --send-key 8F455606 gpg: sending key 8F455606 to hkp server random.sks.keyserver.penguin.de GUIs exist -- but probably with cryptography it is a good idea to have a vague idea what is happening underneath, so you don't send your secret key anywhere, or something equally silly. So learn with the command line, and then chose a GUI for key management later. To be honest I do so little key management I usually use "gpg" directly.
