GetOwnCertificatePack(IEasyUAClientServerApplication) Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Application.Extensions Namespace > IEasyUAClientServerApplicationExtension Class > GetOwnCertificatePack Method : GetOwnCertificatePack(IEasyUAClientServerApplication) Method
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).

Gets the own certificate pack with default certificate sub-id.

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).

Return Value

Returns the own certificate pack, i.e. the dictionary of own certificates, keyed by the certificate type Id.

This method never returns null (Nothing in Visual Basic).

The individual elements of the returned value are never null (Nothing in Visual Basic).

Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

The OPC UA operation has failed. This operation exception in uniformly used to allow common handling of various kinds of errors. The System.Exception.InnerException always contains information about the actual error cause.

This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately.

Remarks

This method operates on certificates with certificate type Ids given by PackCertificateTypeIds.

The actual number of certificates in the application certificate pack may be lower than the count of PackCertificateTypeIds. This is because multiple certificate types may end up using the same certificate. For example, OpcLabs.EasyOpc.UA.Gds.AddressSpace.UACertificateTypeIds.RsaMinApplicationCertificateType specifies an application certificate with RSA key size 1024 or 2048 bits, and OpcLabs.EasyOpc.UA.Gds.AddressSpace.UACertificateTypeIds.RsaSha256ApplicationCertificateType specifies an application certificate with RSA key size 2048, 3072 or 4096 bits. A single certificate with RSA key size of 2048 bits can therefore be used with both these certificate types.

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.

Requirements
