OpenSSH has its possess proprietary certificate structure, which can be employed for signing host certificates or person certificates. For user authentication, the lack of remarkably secure certification authorities combined with The lack to audit who can entry a server by inspecting the server helps make us recommend from applying OpenSSH certificates for consumer authentication.
