this function provides a pure-python implementation of the internals
for the SHA256-Crypt and SHA512-Crypt algorithms; it doesn't
handle any of the parsing/validation of the hash strings themselves.
:arg pwd: password chars/bytes to hash
:arg salt: salt chars to use
:arg rounds: linear rounds cost
:arg use_512: use sha512-crypt instead of sha256-crypt mode
:returns:
encoded checksum chars

rs c @ s( e Zd ZdZd Zed�ZdZdZdZ dS )r aK This class implements the SHA256-Crypt password hash, and follows the :ref:`password-hash-api`.
It supports a variable-length salt, and a variable number of rounds.
The :meth:`~passlib.ifc.PasswordHash.using` method accepts the following optional keywords:
:type salt: str
:param salt:
Optional salt string.
If not specified, one will be autogenerated (this is recommended).
If specified, it must be 0-16 characters, drawn from the regexp range ``[./0-9A-Za-z]``.
:type rounds: int
:param rounds:
Optional number of rounds to use.
Defaults to 535000, must be between 1000 and 999999999, inclusive.
.. note::
per the official specification, when the rounds parameter is set to 5000,
it may be omitted from the hash string.
:type relaxed: bool
:param relaxed:
By default, providing an invalid value for one of the other
keywords will result in a :exc:`ValueError`. If ``relaxed=True``,
and the error can be corrected, a :exc:`~passlib.exc.PasslibHashWarning`
will be issued instead. Correctable errors include ``rounds``
that are too small or too large, and ``salt`` strings that are too long.
.. versionadded:: 1.6
..
commented out, currently only supported by :meth:`hash`, and not via :meth:`using`:
:type implicit_rounds: bool
:param implicit_rounds:
this is an internal option which generally doesn't need to be touched.
this flag determines whether the hash should omit the rounds parameter
when encoding it to a string; this is only permitted by the spec for rounds=5000,
and the flag is ignored otherwise. the spec requires the two different
encodings be preserved as they are, instead of normalizing them.
