You can specify a different location, and an optional password (passphrase) to access the private key file. Although you are not logging in to the remote computer, you must still authenticate using a password. ssh-keyscan prints the host key of the SSH server in Base64-encoded format. Outlined below is a step-by-step guide detailing the process of installing SSH Keys on a Linux server: Step One: Creation of the RSA Key Pair.
