RequireConfidentiality Property (_UAEndpointSelectionPolicy)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Engine.ComTypes Namespace > _UAEndpointSelectionPolicy Interface : RequireConfidentiality Property
Specifies whether communication confidentiality is required (usually provided by encryption).
Syntax
'Declaration
 
Property RequireConfidentiality As Boolean
'Usage
 
Dim instance As _UAEndpointSelectionPolicy
Dim value As Boolean
 
instance.RequireConfidentiality = value
 
value = instance.RequireConfidentiality
bool RequireConfidentiality {get; set;}
property bool RequireConfidentiality {
   bool get();
   void set (    bool value);
}

Property Value

The default value of this property is False.

Remarks

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. This is the case e.g. with the transports based on the HTTPS protocol.

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