I thought configuring GPG was a headache with sub-keys, revocation-certificates, key-servers,...
BUT ssh?!
I mean, ssh user@host -- get it. Easy peacy.

-- There are a quadtrillion config-files in /etc/ and $HOME/.ssh, ssh+sshd, ssha, certificates,.....

The more I want to dig into a topic (even if it's a simple thing like ssh), the more I feel overwhelmed by the tremendous deepness of the topic.

Soo... time to dig deeper into a relatively new topic for me :))
