| AuthConfig | This interface defines the common functionality implemented by Authentication context configuration objects. | 
| AuthConfigFactory | This class is used to obtain AuthConfigProviderobjects that can be used to obtain authentication
 context configuration objects, that is,ClientAuthConfigandServerAuthConfigobjects. | 
| AuthConfigFactory.RegistrationContext | Represents the layer identifier, application context identifier, and description components of an AuthConfigProvider
 registration at the factory. | 
| AuthConfigProvider | This interface is implemented by objects that can be used to obtain authentication context configuration objects,
 that is, ClientAuthConfigorServerAuthConfigobjects. | 
| ClientAuthConfig | This interface encapsulates the configuration of ClientAuthContext objects for a message layer and application
 context (for example, the messaging context of a specific application, or set of applications). | 
| ClientAuthContext | This ClientAuthContext class encapsulates ClientAuthModules that are used to secure service requests made by a
 client, and to validate any responses received to those requests. | 
| RegistrationListener | An implementation of this interface may be associated with an AuthConfigProvider registration at an AuthConfigFactory
 at the time the AuthConfigProvider is obtained for use from the factory. | 
| ServerAuthConfig | This interface describes a configuration of ServerAuthConfiguration objects for a message layer and application
 context (for example, the messaging context of a specific application, or set of applications). | 
| ServerAuthContext | This ServerAuthContext class encapsulates ServerAuthModules that are used to validate service requests received from
 clients, and to secure any response returned for those requests. |
