Key Server

The usual way in which you obtain GPG public keys for email encryption or other purposes is via a key server. There are a few common ones out there, but it's also possible to run your own key server.

ssh into the system with:

ssh myusername@mydomain.com -p 2222

Select Add/Remove Apps then keyserver. You will then be asked for a domain name and if you are using FreeDNS also the code for the domain which can be found under Dynamic DNS on the FreeDNS site (the random string from "quick cron example" which appears after update.php? and before >>). For more details on obtaining a domain and making it accessible via dynamic DNS see the FAQ. Typically the domain name you use will be a subdomain, such as keys.mydomainname.net. It will need to be a domain which you have bought somewhere and own and not one of the FreeDNS subdomains, otherwise you won't be able to get a SSL/TLS certificate for it.

After the install has completed go to Security settings and select Create a new Let's Encrypt certificate and enter the domain name that you are using for the Key server. If the certificate is obtained successfully then you will see a congratulations message.
