-   @short An abstract base class to change expiry asynchronously
-
-   To use a ChangeExpiryJob, first obtain an instance from the
-   CryptoBackend implementation, connect the progress() and result()
-   signals to suitable slots and then start the job with a call
-   to start(). This call might fail, in which case the ChangeExpiryJob
-   instance will have scheduled it's own destruction with a call to
-   QObject::deleteLater().
-
-   After result() is emitted, the ChangeExpiryJob will schedule it's own
-   destruction by calling QObject::deleteLater().
