RequireAuthentication Property (UAEndpointSelectionPolicy)

OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Engine Namespace > UAEndpointSelectionPolicy Class : RequireAuthentication Property
Specifies whether authentication of the communication parties is required.
Public Property RequireAuthentication As Boolean
Dim instance As UAEndpointSelectionPolicy
Dim value As Boolean
instance.RequireAuthentication = value
value = instance.RequireAuthentication
public bool RequireAuthentication {get; set;}
property bool RequireAuthentication {
   bool get();
   void set (    bool value);

The communication parameters are considered as a whole. Even when the OPC UA message security does not provide encryption, the encryption may be provided by the transport. The HTTPS protocol, however, only provides authentication of the server machine, and not of the OPC UA client and server, and thus is not considered as capable of providing authentication of OPC UA communication parties.

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClient.Isolated equals to false), access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of static OpcLabs.EasyOpc.UA.EasyUAClient.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClient.Isolated to true, you need to access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of OpcLabs.EasyOpc.UA.EasyUAClient.IsolatedParameters.

Alternatively, you can override the endpoint selection policy for a specific endpoint by setting it to a non-null value in OpcLabs.EasyOpc.UA.UAEndpointDescriptor.EndpointSelectionPolicy.
