If my SSH identifier isn't named “id_rsa”, SSH authentication fails and defaults to common password authentication. Is there any way I can notify the server to lookup (instantly) the identify of a specific essential?
Though passwords are sent on the server in a very protected way, They are really generally not complicated or extended ample to get resistant to repeated, persistent attackers.
