SectionInformation.ProtectSection Method

The ProtectSection method marks the section for encryption so it will be written in encrypted form on disk.

The following protection providers are included by default:

• DpapiProtectedConfigurationProvider

• RsaProtectedConfigurationProvider

  Note:
  If you call the ProtectSection method with a null parameter or an empty string, the RsaProtectedConfigurationProvider class is used as the protection provider.

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

The following example shows how to use the ProtectSection method.

static public void ProtectSection()
{

    // Get the current configuration file.
    System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);


    // Get the section.
    UrlsSection section =
        (UrlsSection)config.GetSection("MyUrls");


    // Protect (encrypt)the section.
    section.SectionInformation.ProtectSection(
        "RsaProtectedConfigurationProvider");

    // Save the encrypted section.
    section.SectionInformation.ForceSave = true;

    config.Save(ConfigurationSaveMode.Full);

    // Display decrypted configuration 
    // section. Note, the system
    // uses the Rsa provider to decrypt
    // the section transparently.
    string sectionXml =
        section.SectionInformation.GetRawXml();

    Console.WriteLine("Decrypted section:");
    Console.WriteLine(sectionXml);

}
