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.


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

namespace Samples.AspNet
{

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



        [PermissionSet(SecurityAction.Demand, Name="FullTrust")]    
 	 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.Name);
                Console.WriteLine
                         ("Provider description: {0}",
                          provider.Description);

            }

        }

       [PermissionSet(SecurityAction.Demand, Name="FullTrust")]    
	private static void GetProviderName()
        {
            // Get the current provider name.
            string dataProtectionProviderName =
               ProtectedConfiguration.DataProtectionProviderName;
            Console.WriteLine(
                "Data protection provider name: {0}",
                 dataProtectionProviderName);

            // Get the Rsa provider name.
            string rsaProviderName =
                ProtectedConfiguration.RsaProviderName;
            Console.WriteLine(
                "Rsa provider name: {0}",
                 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();


        }
    }
