It wraps a C implementation based on the original SipHash specification, providing a simple interface to compute hash values from a key and message. The module has no runtime dependencies and is distributed as precompiled wheels for modern Python versions and common platforms, making installation straightforward on Linux, macOS, and Windows.\n\nThe package is maintained by the Weblate project and is used in production localization workflows. It is suitable for applications that need a lightweight, collision-resistant hash function\u2014such as hash tables, checksums, or authentication tags\u2014where the speed and security properties of SipHash-2-4 are appropriate. The ISC license permits unrestricted use in open-source and proprietary projects.","worth_installing":"Yes, if you need SipHash-2-4 specifically and want a C-based implementation for performance. The package is actively maintained, has no known vulnerabilities, supports current Python versions, and carries a permissive license. Install friction is moderate due to the compiled extension, but prebuilt wheels are available for standard platforms. If you are unsure whether SipHash-2-4 is the right choice for your use case, verify its security and performance properties against your requirements first."},"id":"siphashc","links":{"html":"https://skillfed.io/packages/siphashc","md":"https://skillfed.io/packages/siphashc.md","pypi":"https://pypi.org/project/siphashc/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-08","license_spdx":"ISC","license_treatment":"permissive","name":"siphashc","python_support":"supports_current","summary":"Python module (in c) for siphash-2-4"},"popularity":{"monthly_downloads":131767,"position":11576,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.8"}
