#Generate the private and the public keys

ssh-keygen -t ed25519 -C "Comment"

#Now the private key must be used connecting to the server
ssh-i /path/of/private/key <user>@<hostip-host-url>

#You must copy the public key (.pub) in the server, specifically in .ssh/autorized_keys
#Or you can add your custom ssh key with: ssh-add github_ssh_key (private key)
