sysutils/ssh-copy-id 10.3pl1 OpenBSD

ssh-copy-id is a script that uses ssh(1) to log into a remote machine (presumably using a login password, so password authentication should be enabled).

It assembles a list of one or more fingerprints and tries to log in with each key, to see if any of them are already installed. It then assembles a list of those keys that failed to log in, and using ssh, enables logins with those keys on the remote server. By default it adds the keys by appending them to the remote user's ~/.ssh/authorized_keys (creating the file, and directory, if necessary).
