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 (requires openssl on your build paths):
python setup.py sdist bdist_wheel
If building a MacOS wheel, also run:
delocate-wheel -v ./dist/*-macosx_*.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/*
