Great video. Well done. Are SSH Host keys only produced by the administrator of the server you are connecting to? I heard you say you generated your own public and private key pair. That public key you mentioned you created as part of that pair is different than the SSH Host key you are talking about in the video, correct? Is the public/private key pair you created to encrypt and decrypt PGP files only and not for host authentication (for example, logging into a server as you do in the video)?

what's the purpose of this process? Does not everyone could get the public key and send to you ? How could the host key or the fingerprint verify the server?

When you changed the host keys, you didnt change your private key on your laptop. So how did your previous private key work with the new host keys?
