This project is a wrapper on `libbase64 <https://github.com/aklomp/base64>`_.
|
|
|
|
|
|
|
|
|
|
It aims to provide a fast base64 implementation for base64 encoding/decoding.
|
|
|
|
|
|
|
|
|
|
Installation
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
.. code::
|
|
|
|
|
|
|
|
|
|
pip install pybase64
|
|
|
|
|
|
|
|
|
|
Usage
|
|
|
|
|
=====
|
|
|
|
|
|
|
|
|
|
``pybase64`` uses the same API as Python base64 "modern interface" (introduced in Python 2.4) for an easy integration.
|
|
|
|
|
|
|
|
|
|
To get the fastest decoding, it is recommended to use the ``pybase64.b64decode`` and ``validate=True`` when possible.
|
|
|
|
|
|
|
|
|
|
.. code:: python
|
|
|
|
|
|
|
|
|
|
import pybase64
|
|
|
|
|
|
|
|
|
|
print(pybase64.b64encode(b'>>>foo???', altchars='_:'))
|
|
|
|
|
# b'Pj4_Zm9vPz8:'
|
|
|
|
|
print(pybase64.b64decode(b'Pj4_Zm9vPz8:', altchars='_:', validate=True))
|
|
|
|
|
# b'>>>foo???'
|
|
|
|
|
|
|
|
|
|
# Standard encoding helpers
|
|
|
|
|
print(pybase64.standard_b64encode(b'>>>foo???'))
|
|
|
|
|
# b'Pj4+Zm9vPz8/'
|
|
|
|
|
print(pybase64.standard_b64decode(b'Pj4+Zm9vPz8/'))
|
|
|
|
|
# b'>>>foo???'
|
|
|
|
|
|
|
|
|
|
# URL safe encoding helpers
|
|
|
|
|
print(pybase64.urlsafe_b64encode(b'>>>foo???'))
|
|
|
|
|
# b'Pj4-Zm9vPz8_'
|
|
|
|
|
print(pybase64.urlsafe_b64decode(b'Pj4-Zm9vPz8_'))
|
