fastcrc

A hyper-fast Python module for computing CRC(8, 16, 32, 64) checksum.

Installation

pip install fastcrc

Usage

from fastcrc import crc8, crc16, crc32, crc64

data = b"123456789"
print(f"crc8 checksum with cdma2000 algorithm: {crc8.cdma2000(data)}")
print(f"crc16 checksum with xmodem algorithm: {crc16.xmodem(data)}")
print(f"crc32 checksum with aixm algorithm: {crc32.aixm(data)}")
print(f"crc64 checksum with ecma_182 algorithm: {crc64.ecma_182(data)}")
print(f"crc16 checksum with xmodem algorithm (with initial data): {crc16.xmodem(b'56789', crc16.xmodem(b'1234'))}")
