in Passlib adhere to. Under Python 2.6 and up, this is an actual
Abstract Base Class built using the :mod:`!abc` module.
See the Passlib docs for full documentation.
FNTc � � t d� �)a
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.

add this method to main documentation.

check if hash's configuration is outside desired bounds,
or contains some other internal option which requires
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.

compile settings into a configuration string for genhash()
.. deprecated:: 1.7
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.
