OpenSSH has its personal proprietary certification format, that may be utilized for signing host certificates or person certificates. For consumer authentication, The dearth of hugely secure certification authorities combined with The shortcoming to audit who can entry a createssh server by inspecting the server tends to make us endorse in opposition to using OpenSSH certificates for consumer authentication.
