between hexadecimal values.
.. function:: unhexlify(data)
Convert hexadecimal data to binary representation. Returns bytes string.
(i.e. inverse of hexlify)
.. function:: a2b_base64(data)
Decode base64-encoded data, ignoring invalid characters in the input.
Conforms to `RFC 2045 s.6.8 <https://tools.ietf.org/html/rfc2045#section-6.8>`_.
Returns a bytes object.
.. function:: b2a_base64(data)
Encode binary data in base64 format, as in `RFC 3548
<https://tools.ietf.org/html/rfc3548.html>`_. Returns the encoded data
