That is it your keys are created, saved, and prepared to be used. You will notice you may have two documents in the ".ssh" folder: "id_rsa" without file extension and "id_rsa.pub."

Our advice is to collect randomness in the course of the full set up of the running method, help you save that randomness in the random seed file. Then boot the system, accumulate some more randomness over the boot, mix from the saved randomness from the seed file, and only then make the host keys.
