Parameters

application

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

gdsEndpointDescriptor

The GDS endpoint acting as OPC UA certificate manager (CM).

parameters

The parameters describing how the certificate should be obtained.

progress

A provider for progress updates.

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(IEasyUAApplication,UAEndpointDescriptor) extension method and its overloads.

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