Configuring Certificate Authority

SSH certificates deliver the best of both worlds – SSH keys and x.509 certificates. While SSH key-based authentication uses public key cryptography to operate, SSH certificate-based authentication simply attaches a signed certificate to each key to verify their identities.

With SSH certificates, you can do away with old-school password-based SSH verification processes. By using a certificate that is signed by a trusted Certificate Authority, you can do away with passwords and leverage a partially automated trust-based certificate authentication process to gain access to systems.
