Options

Without any settings, the plugin uses the VNC 8-char password as password.

When the plugin is installed on the Server PC, you see that the config option is available.

• 1. Passphrase:
  Allow you te set a long password
• 2. Generate client Authetication Key: 
  Pressing the button [Generate client Authetication Key] generate 2 keys.
  xxx_Server_ClientAuth.pubkey and xxx_Viewer_ClientAuth.pkey
  You need to copy the xxx_Viewer_ClientAuth.pkey in the folder of vncviewer.exe
  The xxx_Server_ClientAuth.pubkey stays on the server.
  From now, only the viewer who has the key is able to connect.
