It ships with built-in support for common CRC variants (CRC8, CRC16, CRC32, CRC64) across different polynomial definitions and reflection modes, and allows you to define custom CRC algorithms by specifying polynomial, initial value, and output transformation parameters.\n\nBeyond runtime calculation, the library can generate standalone C code for a given CRC algorithm, intended as a middle ground between size and speed for embedded systems\u2014useful when you need to verify checksums in C without runtime table generation. The library depends on jinja2 for code templating and importlib-metadata for package introspection.","worth_installing":"Yes, if you need CRC calculation and can accept dormant maintenance. The library is stable for its narrow scope (CRC math is well-defined), has no known vulnerabilities, low install friction, and works on modern Python versions. However, maintenance is dormant; use it for non-critical checksums or where you can fork if needed. GPL-3.0-only copyleft is a hard blocker for proprietary closed-source projects."},"id":"crcengine","links":{"html":"https://skillfed.io/packages/crcengine","md":"https://skillfed.io/packages/crcengine.md","pypi":"https://pypi.org/project/crcengine/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2023-04-16","license_spdx":null,"license_treatment":"copyleft","name":"crcengine","python_support":"supports_current","summary":"A library for CRC calculation and code generation"},"popularity":{"monthly_downloads":114626,"position":12286,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.4.0.post1"}
