AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

xxhash provides fast, non-cryptographic hashing via Python bindings to the xxHash C library, supporting xxh32, xxh64, and xxh3 algorithms with a hashlib-compatible interface.

Medium install friction due to compiled C extension; prebuilt wheels cover Python 3.9–3.15 across major platforms (x86_64, ARM, RISC-V, s390x, ppc64le), but source builds require gcc and python-dev. Repository is actively maintained with latest release 1 day old.

BSD-2-Clause is permissive; you may use, modify, and redistribute xxhash freely in commercial and private projects provided you retain the license notice and disclaimer.

Usage

pip install xxhash
import xxhash
result = xxhash.xxh64(b'data').hexdigest()
print(result)

Requires Python ≥3.9; source builds need gcc and python-dev headers.

Verdict: xxhash is a mature, actively maintained binding to a widely-used fast hash library with zero known vulnerabilities, broad platform coverage via prebuilt wheels, and a stable hashlib-compatible API. Install friction is moderate due to C compilation, but wheels mitigate this for most users. Suitable for production use in applications requiring high-speed non-cryptographic hashing.

Needs verification

Whether thread-safety guarantees (per-object locks on 3.13+, GIL serialization on 3.9–3.12) meet your concurrency model.
Performance characteristics relative to your specific data sizes and hashing patterns.
