help keys

Your keys are in ~/.ssh/authorized_keys, one per line. To add one, for
a second computer say, paste its public key on a new line:

  nano ~/.ssh/authorized_keys

Keep the permissions tight or SSH will ignore the file:

  chmod 700 ~/.ssh
  chmod 600 ~/.ssh/authorized_keys

Lost every key you had? Write to admin@runv.club from the email you
signed up with.

Your public keys are also published, so others can find them:

  https://runv.club/~you.keys    the SSH keys above, one per line
  https://runv.club/~you.asc     a PGP key, if you put one in ~/.pgp.asc

For PGP: gpg --armor --export you@example.org > ~/.pgp.asc
Only public keys are taken. Both show up in finger you@runv.club, and
update within 15 minutes.
