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`
- :py:const:`.MEMLIMIT_INTERACTIVE`
- :py:const:`.OPSLIMIT_SENSITIVE`
- :py:const:`.MEMLIMIT_SENSITIVE`
- :py:const:`.OPSLIMIT_MODERATE`
- :py:const:`.MEMLIMIT_MODERATE`
as a guidance for correct settings respectively for the
interactive login and the long term key protecting sensitive data
use cases.
:param size: derived key size, must be between
:py:const:`.BYTES_MIN` and

its length must be exactly :py:const:`.SALTBYTES`

of the key derivation procedure's computational cost;

:param memlimit: the memory occupation component
of the key derivation procedure's computational cost;

Hashes a password with a random salt, using the memory-hard

The default settings for opslimit and memlimit are those deemed
correct for the interactive user login case.
