I usually clear-sign all my e-mails using GPG. To verify these signatures or to send
me a strongly encrypted e-mail, you can get my GPG public key in two ways. The recommended one is
gpg --recv-keys EC2CF2B211AF6AD8
as you will also get the most recent signatures this way.
As an alternative, you can download the
key
(sometimes you'll need to right-click and "Save as..") and import it via
gpg -a --import florian.echtler.asc
