ProtectedConfiguration Class

Provides access to the protected-configuration providers for the current application's configuration file.

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

'Declaration
<PermissionSetAttribute(SecurityAction.LinkDemand, Name := "FullTrust")> _
Public NotInheritable Class ProtectedConfiguration
'Usage
You do not need to declare an instance of a static class in order to access its members.

The ProtectedConfiguration class allows you to obtain information about the providers available to protect sensitive configuration data. You typically use the standard providers, but you can also create custom providers by deriving from the ProtectedConfigurationProvider class.

For more information about protected configuration, see Encrypting Configuration Information Using Protected Configuration.

The following example shows how to use the ProtectedConfiguration class to retrieve a collection of protected-configuration providers and discover their provider name, RSA provider name, and section names.

Imports System.Configuration
Imports System.Collections
