The SASLPrep profile is defined in :rfc:`4013`.
It provides a uniform scheme for normalizing unicode usernames
and passwords before performing byte-value sensitive operations
such as hashing. Among other things, it normalizes diacritic
representations, removes non-printing characters, and forbids
invalid characters such as ``\n``. Properly internationalized
applications should run user passwords through this function
before hashing.
:arg source:
unicode string to normalize & validate
:param param:
Optional noun identifying source parameter in error messages
(Defaults to the string ``"value"``). This is mainly useful to make the caller's error
messages make more sense contextually.
:raises ValueError:
if any characters forbidden by the SASLPrep profile are encountered.
:raises TypeError:
if input is not :class:`!unicode`
:returns:
normalized unicode string
.. note::
This function is not available under Jython,
as the Jython stdlib is missing the :mod:`!stringprep` module

This function is motivated by the fact that
:class:`bytes` instances do not support ``%`` or ``{}`` formatting under Python 3.
This function is an attempt to provide a replacement:
it converts everything to unicode (decoding bytes instances as ``latin-1``),
performs the required formatting, then encodes the result to ``latin-1``.
Calling ``render_bytes(source, *args)`` should function roughly the same as
``source % args`` under Python 2.

This is a wrapper around stdlib's :func:`!crypt.crypt`, which attempts
to provide uniform behavior across Python 2 and 3.

password, as bytes or unicode (unicode will be encoded as ``utf-8``).
:arg hash:
hash or config string, as ascii bytes or unicode.
:returns:
resulting hash as ascii unicode; or ``None`` if the password
couldn't be hashed due to one of the issues:
* :func:`crypt()` not available on platform.
* Under Python 3, if *secret* is specified as bytes,
it must be use ``utf-8`` or it can't be passed
to :func:`crypt()`.
* Some OSes will return ``None`` if they don't recognize
the algorithm being used (though most will simply fall
back to des-crypt).
* Some OSes will return an error string if the input config
is recognized but malformed; current code converts these to ``None``
as well.

the default charset contains all normal alphanumeric characters,
except for the characters ``1IiLl0OoS5``, which were omitted
due to their visual similarity.

.. note::
Using the default character set, on a OS with :class:`!SystemRandom` support,
this function should generate passwords with 5.7 bits of entropy per character.
