enum Viewer.EncryptionLevel

Enumeration of encryption levels.

For more information, see vnc_Viewer_EncryptionLevel in the C API documentation.



Use strong encryption.This is the default.


Use the strongest available encryption, possibly at the cost of speed.


Respect the server’s choice of encryption level. This means the viewer will allow connections to third-party servers, but also represents the weakest security, and may open the user up to man-in-the-middle type attacks. Use with caution. Note: to enable this feature, you will need a Third Party Connectivity Add-on code - contact RealVNC for more information.
