Examples

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.

using System.Configuration;
using System.Collections;
using System.Security.Permissions;

namespace Samples.AspNet
{
  
    // Show how to use the ProtectedConfiguration.
    public sealed class UsingProtectedConfiguration

     private static void GetProviders()
        {
            // Get the providers' collection.
            ProtectedConfigurationProviderCollection
                providers = ProtectedConfiguration.Providers;

            IEnumerator pEnum =
                providers.GetEnumerator();

            foreach (ProtectedConfigurationProvider provider in
                providers)
            {
                Console.WriteLine
                    ("Provider name: {0}",

                          provider.Description);

            string rsaProviderName =
                ProtectedConfiguration.RsaProviderName;

                 rsaProviderName);

            // Get the protected section name.
            string protectedSectionName =
                ProtectedConfiguration.ProtectedDataSectionName;
            Console.WriteLine(
                "Protected section name: {0}",
                 protectedSectionName);
        }

        static void Main(string[] args)
        {

            // Get current and Rsa provider names.
            GetProviderName();

            // Get the providers' collection.
            GetProviders();

Remarks

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.

Fields

DataProtectionProviderName	The name of the data protection provider.
ProtectedDataSectionName	The name of the protected data section.
RsaProviderName	The name of the RSA provider.

Properties

DefaultProvider	Gets the name of the default protected-configuration provider.
Providers	Gets a collection of the installed protected-configuration providers.
