ObtainNewCertificate Method (_EasyUAClientApplication)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Application.ComTypes Namespace > _EasyUAClientApplication Interface : ObtainNewCertificate Method
The GDS endpoint acting as OPC UA certificate manager (CM).
The parameters describing how the certificate should be obtained.
Obtains a new application instance certificate from the certificate manager, and stores it for subsequent usage.
Syntax
'Declaration

Parameters

gdsEndpointDescriptor
The GDS endpoint acting as OPC UA certificate manager (CM).
parameters
The parameters describing how the certificate should be obtained.

Return Value

Returns the certificate obtained from the certificate manager.
Exceptions
ExceptionDescription
A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.
An operation that the thread was execution has been cancelled.
The OPC UA operation has failed.
An error has occurred during method execution.
Remarks

The operation is synchronous. It can take considerable time to execute, 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).

For an alternative based on asynchronous programming model (APM, System.IAsyncResult) pattern, see the BeginObtainNewCertificate method and related extension methods.

For a task-based asynchronous programming pattern alternative, see the OpcLabs.EasyOpc.UA.Application.Extensions.IEasyUAApplicationExtension.ObtainNewCertificateAsync extension method and its overloads.
