It attempts to use a compiled C++ implementation for speed when Cython is available, and falls back to a pure Python implementation from the fnvhash package otherwise. The library exports a single primary function, fnv1a_32, which takes bytes as input and returns an integer hash value.\n\nThe package targets developers who need fast, non-cryptographic hashing\u2014for example, in hash tables, bloom filters, or data deduplication. It supports Python 3.10 through 3.14 and is distributed as pre-compiled wheels for common platforms (Linux, macOS, Windows) and architectures (x86_64, ARM), reducing installation friction on most systems.","worth_installing":"Yes, if you need a fast FNV-1a implementation and accept that this is a non-cryptographic hash. The package is actively maintained, has no known vulnerabilities, supports modern Python versions, and offers both compiled and pure-Python paths. Install it for performance-sensitive hashing tasks where FNV-1a is already your algorithm of choice; do not use it as a general-purpose cryptographic hash."},"id":"fnv-hash-fast","links":{"html":"https://skillfed.io/packages/fnv-hash-fast","md":"https://skillfed.io/packages/fnv-hash-fast.md","pypi":"https://pypi.org/project/fnv-hash-fast/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-16","license_spdx":"MIT","license_treatment":"permissive","name":"fnv-hash-fast","python_support":"supports_current","summary":"A fast version of fnv1a"},"popularity":{"monthly_downloads":781477,"position":5079,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.3"}
