ProtectedConfigurationSection Class

Definition

Provides programmatic access to the configProtectedData configuration section. This class cannot be inherited.

public sealed class ProtectedConfigurationSection : System.Configuration.ConfigurationSection
type ProtectedConfigurationSection = class
    inherit ConfigurationSection

ProtectedConfigurationSection

Examples

The following configuration file excerpt shows how to declaratively specify protected data providers.

<configProtectedData defaultProvider="RsaProtectedConfigurationProvider">
  <providers>
    <clear />
      <add keyContainerName="NetFrameworkConfigurationKey" cspProviderName="" useMachineContainer="true" useOAEP="false" description="Uses RsaCryptoServiceProvider to encrypt and decrypt" name="RsaProtectedConfigurationProvider" type="System.Configuration.RsaProtectedConfigurationProvider,System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

      <add useMachineProtection="true" description="Uses CryptProtectData and CryptUnProtectData Windows APIs to encrypt and decrypt" keyEntropy="" name="DataProtectionConfigurationProvider" type="System.Configuration.DpapiProtectedConfigurationProvider,System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

  </providers>
</configProtectedData>

The following code example shows how to use the ProtectedConfigurationSection class to programmatically access values in the configProtectedData configuration file section.

using System.IO;
using System.Configuration;

namespace Samples.Aspnet

    // Shows how to use ProtectedConfigurationSection.

                Configuration config =
                    ConfigurationManager.OpenExeConfiguration(
                    ConfigurationUserLevel.None);

                // Get the protected configuration section.
                ProtectedConfigurationSection pcSection =
                    (System.Configuration.ProtectedConfigurationSection)
                    config.GetSection("configProtectedData");

                // Get the current DefaultProvider.
                Console.WriteLine(
                    "Protected configuration section default provider:");
                Console.WriteLine("  {0}", pcSection.DefaultProvider);
            }
            catch (ConfigurationErrorsException e)

Remarks

The configProtectedData configuration file section contains a collection of protected data providers in its providers element.

Note

You can use the Aspnet_regiis.exe tool to encrypt and decrypt configuration sections. See Encrypting Configuration Information Using Protected Configuration.
