It exposes multiple algorithm implementations (such as cdma2000 for CRC-8, xmodem for CRC-16, aixm for CRC-32, and ecma_182 for CRC-64) as importable functions that accept byte data and return computed checksums. The module has no runtime dependencies and is distributed as pre-compiled wheels for most common platforms.\n\nTypical use cases include data integrity verification, network protocol implementations, and embedded systems communication where CRC checksums are required. The package is actively maintained, supports Python 3.7 and later, and carries permissive MIT licensing.","worth_installing":"Yes. fastcrc is actively maintained, carries no security vulnerabilities, has zero runtime dependencies, and offers permissive MIT licensing. Medium install friction is acceptable given pre-built wheels for common platforms. Install it if you need CRC checksums and want compiled-speed performance; skip it if you only need Python's built-in hashlib.crc32 or can tolerate pure-Python performance."},"id":"fastcrc","links":{"html":"https://skillfed.io/packages/fastcrc","md":"https://skillfed.io/packages/fastcrc.md","pypi":"https://pypi.org/project/fastcrc/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-06","license_spdx":null,"license_treatment":"permissive","name":"fastcrc","python_support":"supports_current","summary":"A hyper-fast Python module for computing CRC(8, 16, 32, 64) checksum"},"popularity":{"monthly_downloads":949773,"position":4659,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.3.6"}
