user_canceled:  This alert notifies the recipient that the sender is
      canceling the handshake for some reason unrelated to a protocol
      failure.  If a user cancels an operation after the handshake is
      complete, just closing the connection by sending a "close_notify"
      is more appropriate.  This alert SHOULD be followed by a
      "close_notify".  This alert generally has AlertLevel=warning.
