:arg name:
    This must be the name of a recognized prf.
    Currently this only recognizes names with the format
    :samp:`hmac-{digest}`, where :samp:`{digest}`
    is the name of a hash function such as
    ``md5``, ``sha256``, etc.

    todo: restore text about callables.

:raises ValueError: if the name is not known
:raises TypeError: if the name is not a callable or string

:returns:
    a tuple of :samp:`({prf_func}, {digest_size})`, where:

    * :samp:`{prf_func}` is a function implementing
      the specified PRF, and has the signature
      ``prf_func(secret, message) -> digest``.

    * :samp:`{digest_size}` is an integer indicating
      the number of bytes the function returns.

Usage example::

    >>> from passlib.utils.pbkdf2 import get_prf
    >>> hmac_sha256, dsize = get_prf("hmac-sha256")
    >>> hmac_sha256
    <function hmac_sha256 at 0x1e37c80>
    >>> dsize
    32
    >>> digest = hmac_sha256('password', 'message')

.. deprecated:: 1.7

    This function is deprecated, and will be removed in Passlib 2.0.
    This only related replacement is :func:`passlib.crypto.digest.compile_hmac`.

    This algorithm has been deprecated, new code should use PBKDF2.
    Among other limitations, ``keylen`` cannot be larger
    than the digest size of the specified hash.
