: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 `_. Returns a bytes object. .. function:: b2a_base64(data, *, newline=True) Encode binary data in base64 format, as in `RFC 3548 `_. Returns the encoded data followed by a newline character if newline is true, as a bytes object.
