eth-hash: The Ethereum hashing function, keccak256, sometimes (erroneously) called sha3
Project description
The Ethereum hashing function, keccak256, sometimes (erroneously) called sha3
Note: the similarly named pyethash has a completely different use: it generates proofs of work.
This is a low-level library, intended to be used internally by other Ethereum tools. If you’re looking for a convenient hashing tool, check out `eth_utils.keccak() <https://github.com/ethereum/eth-utils#crypto-utils>`__ which will be a little friendlier, and provide access to other helpful utilities.

Quickstart

Development Environment Setup
You can set up your dev environment with:
git clone git@github.com:carver/eth-hash.git
cd eth-hash
virtualenv -p python3 venv
. venv/bin/activate
pip install -e .[dev]Testing Setup
During development, you might like to have tests run on every file save.
Show flake8 errors on file change:
# Test flake8
when-changed -v -s -r -1 eth_hash/ tests/ -c "clear; flake8 eth_hash tests && echo 'flake8 success' || echo 'error'"Run multi-process tests in one command, but without color:
# in the project root:
pytest --numprocesses=4 --looponfail --maxfail=1
# the same thing, succinctly:
pytest -n 4 -f --maxfail=1Run in one thread, with color and desktop notifications:
cd venv
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on eth-hash failed'" ../tests ../eth_hashRelease setup
For Debian-like systems:
apt install pandoc
To release a new version:
make release bump=$$VERSION_PART_TO_BUMP$$How to bumpversion
The version format for this repo is {major}.{minor}.{patch} for stable, and {major}.{minor}.{patch}-{stage}.{devnum} for unstable (stage can be alpha or beta).
To issue the next version in line, specify which part to bump, like make release bump=minor or make release bump=devnum.
If you are in a beta version, make release bump=stage will switch to a stable.
To issue an unstable version when the current version is stable, specify the new version explicitly, like make release bump="--new-version 4.0.0-alpha.1 devnum"
