    .. deprecated:: 1.6
        This class has been deprecated, and will be removed in Passlib 1.8.
        All of its functionality has been rolled into :class:`CryptContext`.

    This class previously stored the configuration options for the
    CryptContext class. In the interest of interface simplification,
    all of this class' functionality has been rolled into the CryptContext
    class itself.
    The documentation for this class is now focused on  documenting how to
    migrate to the new api. Additionally, where possible, the deprecation
    warnings issued by the CryptPolicy methods will list the replacement call
    that should be used.

    Constructors
    ============
    CryptPolicy objects can be constructed directly using any of
    the keywords accepted by :class:`CryptContext`. Direct uses of the
    :class:`!CryptPolicy` constructor should either pass the keywords
    directly into the CryptContext constructor, or to :meth:`CryptContext.update`
    if the policy object was being used to update an existing context object.

    In addition to passing in keywords directly,
    CryptPolicy objects can be constructed by the following methods:

    .. automethod:: from_path
    .. automethod:: from_string
    .. automethod:: from_source
    .. automethod:: from_sources
    .. automethod:: replace

    Introspection
    =============
    All of the informational methods provided by this class have been deprecated
    by identical or similar methods in the :class:`CryptContext` class:

    .. automethod:: has_schemes
    .. automethod:: schemes
    .. automethod:: iter_handlers
    .. automethod:: get_handler
    .. automethod:: get_options
    .. automethod:: handler_is_deprecated
    .. automethod:: get_min_verify_time

    Exporting
    =========
    .. automethod:: iter_config
    .. automethod:: to_dict
    .. automethod:: to_file
    .. automethod:: to_string

    .. note::
        CryptPolicy are immutable.

S(sLoad new configuration into CryptContext, replacing existing config.

        :arg source:
            source of new configuration to load.
            this value can be a number of different types:

            * a :class:`!dict` object, or compatible Mapping

                the key/value pairs will be interpreted the same
                keywords for the :class:`CryptContext` class constructor.

            * a :class:`!unicode` or :class:`!bytes` string

                this will be interpreted as an INI-formatted file,
                and appropriate key/value pairs will be loaded from
                the specified *section*.

            * another :class:`!CryptContext` object.

                this will export a snapshot of its configuration
                using :meth:`to_dict`.

        :type update: bool
        :param update:
            By default, :meth:`load` will replace the existing configuration
            entirely. If ``update=True``, it will preserve any existing
            configuration options that are not overridden by the new source,
            much like the :meth:`update` method.

        :type section: str
        :param section:
            When parsing an INI-formatted string, :meth:`load` will look for
            a section named ``"passlib"``. This option allows an alternate
            section name to be used. Ignored when loading from a dictionary.

        :type encoding: str
        :param encoding:
            Encoding to use when decode bytes from string.
            Defaults to ``"utf-8"``. Ignoring when loading from a dictionary.

        :raises TypeError:
            * If the source cannot be identified.
            * If an unknown / malformed keyword is encountered.

        :raises ValueError:
            If an invalid keyword value is encountered.

        .. note::

            If an error occurs during a :meth:`!load` call, the :class:`!CryptContext`
            instance will be restored to the configuration it was in before
            the :meth:`!load` call was made; this is to ensure it is
            *never* left in an inconsistent state due to a load error.

        in which case the secret should be re-hashed.

        This function is the core of CryptContext's support for hash migration:
        This function takes in a hash string, and checks the scheme,
        number of rounds, and other properties against the current policy.
        It returns ``True`` if the hash is using a deprecated scheme,
        or is otherwise outside of the bounds specified by the policy
        (e.g. the number of rounds is lower than :ref:`min_rounds <context-min-rounds-option>`
        configuration for that algorithm).
        If so, the password should be re-hashed using :meth:`hash`
        Otherwise, it will return ``False``.

        :type hash: unicode or bytes
        :arg hash:
            The hash string to examine.

        :type scheme: str or None

            configured for this context (see the
            :ref:`schemes <context-schemes-option>` option).
            If no scheme is specified, it will be identified
            based on the value of *hash*.

            If specified, this will cause any category-specific defaults to
            be used when determining if the hash needs to be updated
            (e.g. is below the minimum rounds).

        :type secret: unicode, bytes, or None

            it's for forward-compatibility with any future

            If provided, Passlib assumes the secret has already been

    This is a subclass of CryptContext which takes in a set of arguments
    exactly like CryptContext, but won't import any handlers
    (or even parse its arguments) until
    the first time one of its methods is accessed.

    :arg schemes:
        The first positional argument can be a list of schemes, or omitted,
        just like CryptContext.

    :param onload:

        If a callable is passed in via this keyword,
        it will be invoked at lazy-load time
        with the following signature:
        ``onload(**kwds) -> kwds``;
        where ``kwds`` is all the additional kwds passed to LazyCryptContext.
        It should perform any additional deferred initialization,
        and return the final dict of options to be passed to CryptContext.

        .. versionadded:: 1.6

    :param create_policy:

        .. deprecated:: 1.6
            This option will be removed in Passlib 1.8,
            applications should use ``onload`` instead.

    :param kwds:

        All additional keywords are passed to CryptContext;
        or to the *onload* function (if provided).

    This is mainly used internally by modules such as :mod:`passlib.apps`,
    which define a large number of contexts, but only a few of them will be needed
    at any one time. Use of this class saves the memory needed to import
    the specified handlers until the context instance is actually accessed.
    As well, it allows constructing a context at *module-init* time,
    but using :func:`!onload()` to provide dynamic configuration
    at *application-run* time.

    .. note:: 
        This class is only useful if you're referencing handler objects by name,
        and don't want them imported until runtime. If you want to have the config
        validated before your application runs, or are passing in already-imported
        handler instances, you should use :class:`CryptContext` instead.
