  Description
  Callback
  Implementations of this interface are passed to a `CallbackHandler`, allowing underlying security services the ability to interact with a calling application to retrieve specific authentication data such as usernames and passwords, or to display certain information, such as error and warning messages.
  CallbackHandler
  An application implements a `CallbackHandler` and passes it to underlying security services so that they may interact with the application to retrieve specific authentication data, such as usernames and passwords, or to display certain information, such as error and warning messages.
  UnsupportedCallbackException
  Signals that a `CallbackHandler` does not recognize a particular `Callback`.
