ProtectedConfigurationProviderCollection Class

Note: This class is new in the .NET Framework version 2.0.

Provides a collection of ProtectedConfigurationProvider objects.

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

public class ProtectedConfigurationProviderCollection : ProviderCollection
public class ProtectedConfigurationProviderCollection extends ProviderCollection
public class ProtectedConfigurationProviderCollection extends ProviderCollection

The Providers property of the ProtectedConfiguration class is a ProtectedConfigurationProviderCollection of all protected-configuration providers available to your application.

You can encrypt sections of a configuration file in order to protect sensitive information used by your application. This improves security by making it difficult for unauthorized access even if an attacker gains access to your configuration file.

The .NET Framework includes two protected configuration providers that can be used to encrypt sections of a configuration file, the RSAProtectedConfigurationProvider, which uses the RSACryptoServiceProvider to encrypt configuration sections, and the DPAPIProtectedConfigurationProvider, which uses the Windows Data Protection API (DPAPI) to encrypt configuration sections.

You may have a requirement to encrypt sensitive information using an algorithm other than the RSA or DPAPI providers. In this case, you can build your own custom Protected Configuration provider. The ProtectedConfigurationProvider is an abstract base class that you must inherit from in order to create your own protected-configuration provider.

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