Klexx / chacha20.py
Created December 5, 2017 15:52 — forked from chiiph/chacha20.py
Python implementation of the stream cipher ChaCha20. The idea is to use numpy as the "numeric backend" to avoid side channel attacks. THIS IS JUST AN EXPERIMENT, DO NOT USE IN PRODUCTION.
# Based on http://cr.yp.to/streamciphers/timings/estreambench/submissions/salsa20/chacha8/ref/chacha.c

ChaCha20 stream cipher in Python 3
# Pure Python ChaCha20
# Based on Numpy implementation: https://gist.github.com/chiiph/6855750
# Based on http://cr.yp.to/chacha.html
#
# I wanted an implementation of ChaCha in clean, understandable Python
# as a way to get a handle on the algorithm for porting to another language.
# There are plenty of bindings but few pure implementations, because
# Pure Python is too slow for normal practical use in Cryptography.
#
# The preceding implementation used NumPy, which avoided a lot of the
