Generating a key is simple enough: ssh-keygen -t ed25519Īdd a passphrase if you like. There's a great stackoverflow thread discussing the various merits of key types, enjoy that rabbit hole. Ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIK4oWAP5LyXJsqOdu0X0m1BOYqQrBIDzj/63yAdC5vP8 ed25519 public key makes the rsa keys look a bit gross don't they? The caveat here is that older versions of SSH don't support ed25519 but you probably shouldn't be exposing those old versions to the internet anyways.

They mean you don't need to use passwords to login to your remote systems and are much more secure. Keys are an absolute fundamental for using SSH. Connect and control any server anywhere in the world? Yes please! In this article I will outline a few tips and tricks I've accrued over the years to make SSH even better. What would we do without SSH? I must use it hundreds of times a day for all sorts of tasks.
