The other day I added my PGP key to this website, which you can view here. I also added support for Web Key Directory to make it a bit easier to download and verify my key. WKD provides a standard method for users to easily fetch PGP keys from the internet. That means that you can download my key from GPG without having to search for it on my website. Here’s how you do it:
gpg --locate-key firstname.lastname@example.org
It’s that simple. If you want to implement this on your own site, here’s the tutorial I used. You can also use OpenPGP’s “WKD as a Service” if you’re looking for something easier, but I recommend doing it yourself on your own server if you can.
