It exposes an interface compatible with Python's standard hashlib module, so you can use it like any other hash function\u2014calling update() to feed data and digest() to retrieve the result. The package extends hashlib's interface with an intdigest() method that returns the hash as a 64-bit signed integer instead of bytes, which is the conventional representation for SipHash values.\n\nThe implementation is streaming-capable, meaning you can hash large amounts of data incrementally rather than loading it all into memory at once. It ships as precompiled binary wheels for Python 3.7\u20133.14 on macOS, Linux, and Windows, eliminating the need to compile C code on most systems. The underlying C code is based on the c-siphash library and ultimately derives from the SipHash reference implementation, so it is well-established and widely reviewed.","worth_installing":"Yes, if you specifically need SipHash and want a hashlib-compatible interface with streaming support. The package is stable, well-maintained enough for production use, has no known vulnerabilities, and provides convenient precompiled wheels. However, the aging maintenance status (346 days since last release) and unclear license metadata warrant a quick review of your licensing requirements before committing. If you only need a general-purpose hash function, Python's built-in hashlib is a simpler choice."},"id":"siphash24","links":{"html":"https://skillfed.io/packages/siphash24","md":"https://skillfed.io/packages/siphash24.md","pypi":"https://pypi.org/project/siphash24/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-09-02","license_spdx":"Apache-2.0 OR LGPL-2.1-or-later","license_treatment":"unclear","name":"siphash24","python_support":"supports_current","summary":"Streaming-capable SipHash-1-3 and SipHash-2-4 Implementation"},"popularity":{"monthly_downloads":510712,"position":6265,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.8"}
