:mod:`binascii` -- binary/ASCII conversions
|
|
===========================================
|
|
|
|
.. module:: binascii
|
|
:synopsis: binary/ASCII conversions
|
|
|
|
|see_cpython_module| :mod:`python:binascii`.
|
|
|
|
This module implements conversions between binary data and various
|
|
encodings of it in ASCII form (in both directions).
|
|
|
|
Functions
|
|
---------
|
|
|
|
.. function:: hexlify(data, [sep])
|
|
|
|
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)
|
|
|
|
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.
|
|
|
|
.. function:: crc32(data, [value])
|
|
|
|
Compute CRC-32, the 32-bit checksum of *data*, starting with an initial CRC
|
|
of *value*. The default initial CRC is zero. The algorithm is consistent
|
|
with the ZIP file checksum.
