Property Value

For directory certificate store, this is a directory name. For system (Windows, Linux, ...) certificate store, this is a "LocalMachine\" or "CurrentUser\" followed by a store name.

The list of trusted certificates for application instances.

Some UA applications will use self-signed certificates (certificates without a CA) which means that every application which communicates with it must be configured to trust it.

Administrators may designate a certificate store that contains trusted UA application instance certificates(this store should not be the same as the store used for CAs certificates). Alternately, Administrators may enter the certificates explicitly in this list.

In order to obtain or modify this parameter, access the OpcLabs.EasyOpc.UA.Engine.UAClientServerApplicationParameters.ApplicationManifest property of OpcLabs.EasyOpc.UA.Application.EasyUAApplicationCore.ApplicationParameters property of static EasyUAApplication.Instance.

When this object is used to override properties of another application manifest, an empty value in this property keeps the original value. A non-empty value in this property overrides the original value. Use "#" to set the value back to an empty string.

In order to obtain or modify this parameter, access the OpcLabs.EasyOpc.UA.Engine.UAClientServerApplicationParameters.ApplicationManifest property of OpcLabs.EasyOpc.UA.Application.EasyUAApplicationCore.ApplicationParameters property of static EasyUAApplication.Instance.

// This example demonstrates how to configure the location of the certificate stores to directories specified by absolute
// paths.


// Obtain the application interface.

// Set the application certificate store paths.
// Note that this only works once in each host process.
// If this code is used in a Web application, make sure it is executed at the beginning of every page that can be used to 
// enter your application. You will most likely make it into a subroutine then.
