Abstract Base Class built using the :mod:`!abc` module.

Hash secret, returning result.
Should handle generating salt, etc, and should return string
containing identifier, salt & other configuration, as well as digest.
:param \\*\\*settings_kwds:
Pass in settings to customize configuration of resulting hash.
.. deprecated:: 1.7
Starting with Passlib 1.7, callers should no longer pass settings keywords
(e.g. ``rounds`` or ``salt`` directly to :meth:`!hash`); should use
``.using(**settings).hash(secret)`` construction instead.
Support will be removed in Passlib 2.0.
:param \\*\\*context_kwds:
Specific algorithms may require context-specific information (such as the user login).

Legacy alias for :meth:`hash`.
.. deprecated:: 1.7
This method was renamed to :meth:`!hash` in version 1.7.
This alias will be removed in version 2.0, and should only
be used for compatibility with Passlib 1.3 - 1.6.

Return another hasher object (typically a subclass of the current one),
which integrates the configuration options specified by ``kwds``.
This should *always* return a new object, even if no configuration options are changed.

:returns:
typically returns a subclass for most hasher implementations.

check if hash's configuration is outside desired bounds,

updating the password hash.
:param hash:
hash string to examine
:param secret:
optional secret known to have verified against the provided hash.
(this is used by some hashes to detect legacy algorithm mistakes).
:return:
whether secret needs re-hashing.

As of 1.7, this method is deprecated, and slated for complete removal in Passlib 2.0.
For all known real-world uses, hashing a constant string
should provide equivalent functionality.
This deprecation may be reversed if a use-case presents itself in the mean time.
