Parameters

application

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

In client applications, this is typically obtained by calling System.IServiceProvider.GetService(System.Type) on the OpcLabs.EasyOpc.UA.IEasyUAClient (EasyUAClient object) with the type of OpcLabs.EasyOpc.UA.Application.IEasyUAClientServerApplication as an argument.

The value of this parameter cannot be null (Nothing in Visual Basic).

arguments

The parameters describing how the certificate should be obtained.

The value of this parameter cannot be null (Nothing in Visual Basic).

Return Value

The BeginObtainNewCertificateOrCertificatePack methods begin an asynchronous operation that obtains a new application own certificate or certificate pack from the certificate manager, and stores it for subsequent usage.

When certificate pack is used, this method operates on certificates with certificate type Ids given by PackCertificateTypeIds.

When CertificateTypeId in arguments is null (Nothing in Visual Basic), the operation obtains the whole certificate pack. Otherwise, it obtains the certificate of certificate type specified by the CertificateTypeId in arguments. If the specified certificate type Id is Null, the default certificate type Id from DefaultCertificateTypeId is used instead.

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 EndObtainNewCertificateOrCertificatePack method. The operation can be cancelled using the CancelObtainNewCertificateOrCertificatePack method.

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

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

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
