===========================================
2014-12-01 18:51:12 -05:00
.. module:: binascii
2014-12-01 18:51:12 -05:00
:synopsis: binary/ASCII conversions
|see_cpython_module| :mod:`python:binascii`.
2014-12-01 18:51:12 -05:00
This module implements conversions between binary data and various
encodings of it in ASCII form (in both directions).
Functions
---------
.. function:: hexlify(data, [sep])
2014-12-01 18:51:12 -05:00
Convert the bytes in the *data* object to a hexadecimal representation.
Returns a bytes object.
If the additional argument *sep* is supplied it is used as a separator
between hexadecimal values.
.. function:: unhexlify(data)
2016-04-27 08:47:33 -04:00
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, *, newline=True)
Encode binary data in base64 format, as in `RFC 3548
<https://tools.ietf.org/html/rfc3548.html>`_. Returns the encoded data
followed by a newline character if newline is true, as a bytes object.
