Serializable hash objects

Project description

Hashstate

This is a Python C extension module that forks the hashlib implementation from CPython itself to add support for a single feature: the ability to serialize and deserialize hash objects so that the hash objects do not have to persist in memory for the whole duration of the hash computation.

Usage

pip install hashstate

import hashstate

# Contains all the same constructors as hashlib
hash1 = hashstate.sha512()
hash1.update('...')
s = hash1.serialize()  # gives back bytes object

hash2 = hashstate.sha512()
hash2.deserialize(s)
assert hash1.digest() == hash2.digest()

Developers

Build the package:

python setup.py sdist bdist_wheel

If building a MacOS wheel, also run:

delocate-wheel ./dist/*.whl

Build the linux bdist_wheels (64-bit only at the moment):

docker build -t manylinux-hashstate .
docker run --rm -v $(pwd)/dist:/dist manylinux-hashstate

Upload to pypi

twine upload dist/*
