It exposes individual functions for each CRC type (e.g., libscrc.modbus, libscrc.xmodem, libscrc.crc32) that accept byte strings or bytearrays and return integer checksums. The library supports both single-pass calculation and incremental computation, where a previous CRC result can be passed as a second argument to continue checksumming additional data.\n\nThe package is distributed as pre-compiled wheels for CPython 2.7 and 3.4\u20133.12 across Linux (x86_64, ARM, ARM64), macOS, Windows, and musl-based systems, minimizing compilation overhead on common platforms. It has no runtime dependencies beyond the Python standard library and wheel metadata.","worth_installing":"Yes, if you need CRC calculation and can accept GPLv3+ licensing. The package is actively maintained, widely pre-compiled, and covers an unusually comprehensive set of CRC variants. Install friction is low for most modern Python environments. Not suitable for proprietary projects without a separate license agreement."},"id":"libscrc","links":{"html":"https://skillfed.io/packages/libscrc","md":"https://skillfed.io/packages/libscrc.md","pypi":"https://pypi.org/project/libscrc/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2022-08-18","license_spdx":null,"license_treatment":"copyleft","name":"libscrc","python_support":"unspecified","summary":"Library for calculating CRC3/CRC4/CRC8/CRC16/CRC24/CRC32/CRC64/CRC82"},"popularity":{"monthly_downloads":498874,"position":6327,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.8.1"}
