Parameters

application

The OPC UA client/server application object that will perform the operation.

parameters

The parameters describing how the certificate should be obtained.

asyncCallback

The delegate that is executed when the operation completes.

state

An object that contains any additional user-defined data.

progress

A provider for progress updates.

Return Value

The operation is asynchronous, because it involves multiple steps, and waiting for a finalization of the request by the GDS (see the OpcLabs.EasyOpc.UA.Gds.IEasyUACertificateManagement.FinishRequest method). End of the operation is handled by the EndObtainNewCertificate method. The operation can be cancelled using the CancelObtainNewCertificate method.

For a synchronous alternative, see the ObtainNewCertificate(IEasyUAClientServerApplication,UAEndpointDescriptor) extension method and its overloads.

For a task-based asynchronous programming pattern alternative, see the ObtainNewCertificateAsync(IEasyUAClientServerApplication,UAEndpointDescriptor) extension method and its overloads.

The operation first updates the application's registration in the GDS, before making a request to the certificate manager.
