#+title: SSH keys

Your key is your identity on gitbay: there are no passwords. Registering
pastes the public half of a key pair; the private half never leaves your
machine.

* Make a key

#+begin_src sh
ssh-keygen -t ed25519 -C "you@host"
#+end_src

Accept the default path. Two files land in =~/.ssh/=: =id_ed25519= is
private, keep it; =id_ed25519.pub= is public, paste it.

* Get the public half

#+begin_src sh
cat ~/.ssh/id_ed25519.pub
#+end_src

One line, starting =ssh-ed25519 AAAA…= and ending with your comment. That
whole line is what the registration form and =register= want.

* Check it works

#+begin_src sh
ssh git@<host> whoami
#+end_src
