I actually use Ubuntu for my work laptop as a developer, and I use whatever default SSH executable comes with Ubuntu. I know there's some standards to `id_rsa` and `known_hosts` or `authorized_hosts`; and I use ~/.ssh/config for establishing new keys, like `work_rsa` which I think is essentially the same structure as the set app SSH config.
