HighwayHash is a pseudorandom function (i.e. keyed hash function) optimized for speed on short messages, designed by Jyrki Alakuijala, Bill Cox and Jan Wassenberg of Google Research.
This package provides tested, performant Python 3 CFFI bindings to the HighwayHash reference implementation, including support for all output lengths.
You can install this package using pip or the included setup.py script:
# Using pip
pip install highwayhash-cffi
# Using setup.py
python setup.py install
from highwayhash import *
# Demonstration key and data
key = b"\0" * 32
data = b"\0" * 64
# HighwayHash with a 64-bit output length
output = highwayhash_64(key, data)
# HighwayHash with a 128-bit output length
output = highwayhash_128(key, data)
# HighwayHash with a 256-bit output length
output = highwayhash_256(key, data)BSD 3-Clause License
