Getting started¶
pybase64
is a wrapper on libbase64.
It aims to provide a fast base64 implementation for base64 encoding/decoding.
Installation¶
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 b64decode()
and validate=True when possible.
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_'))
# b'>>>foo???'
Check API Reference for more details.
A command-line tool is also provided. It has encode, decode and benchmark subcommands.
usage: pybase64 [-h] [-V] {benchmark,encode,decode} ...
pybase64 command-line tool.
positional arguments:
{benchmark,encode,decode}
tool help
benchmark -h for usage
encode -h for usage
decode -h for usage
optional arguments:
-h, --help show this help message and exit
-V, --version show program's version number and exit
