OpenSSH has its individual proprietary certification format, that may be used for signing host certificates or consumer certificates. For user authentication, The shortage of really safe certification authorities combined with The shortcoming to audit who will accessibility a server by inspecting the server makes us advocate against working with OpenSSH certificates for user authentication.
