blake2b-py
Blake2b hashing in Rust with Python bindings.
Developing
Install dependencies and build the Python extension in a virtual environment:
UV_CACHE_DIR=/tmp/uv-cache uv run --group test maturin develop
Run the test suites:
UV_CACHE_DIR=/tmp/uv-cache uv run --group test pytest
PYO3_PYTHON=.venv/bin/python cargo test test_
The slow EIP-152 vector can be run explicitly:
PYO3_PYTHON=.venv/bin/python cargo test --release test_f_eip_152_vec_8 -- --ignored --nocapture
Rust benchmarks use unstable Rust benchmark support and require nightly:
PYO3_PYTHON=.venv/bin/python cargo +nightly bench --features nightly-benches
You may need to specify the MACOSX_DEPLOYMENT_TARGET environment variable to
your version of macOS.
Building and Releasing
Build local artifacts with maturin:
UV_CACHE_DIR=/tmp/uv-cache uv run --group build maturin build --release
The committed package version in Cargo.toml is intentionally the invalid
release sentinel 0.0.0. Create a GitHub release with a semantic-version tag
such as v0.5.0; the publish workflow validates the tag and replaces the
sentinel before Maturin builds the wheels and source distribution. A local
build retains the sentinel version and must not be published.
PyPI must be configured to trust the ApeWorX/blake2b-py GitHub repository and
the .github/workflows/publish.yaml workflow before the release job can
publish.
