Our advice is to collect randomness throughout the whole installation in the operating process, save that randomness in the random seed file. Then boot the method, obtain some more randomness during the boot, mix from the saved randomness from the seed file, and only then crank out the host keys.

Incorporate your SSH non-public essential towards the ssh-agent and retail store your passphrase from the keychain. Should you created your critical with createssh a special identify, or In case you are introducing an current important which has a different title, replace id_ed25519
