    Derive a ``size`` bytes long key from a caller-supplied
    ``password`` and ``salt`` pair using the scryptsalsa208sha256
    memory-hard construct.


    the enclosing module provides the constants

        - :py:const:`.OPSLIMIT_INTERACTIVE`

    as a guidance for correct settings respectively for the
    interactive login and the long term key protecting sensitive data
    use cases.
