However, sometimes you must compute a CRC in software, for example in a C or C++ program that will run on a microcontroller.

Sign in LibCRC is an MIT licensed library written in C containing various checksum algorithms.

Simple CRC32 C-code. Here is a simple implementation of the commonly used CRC32 checksum using the reverse polynomial 0xEDB88320. The algorithm is

Multiple variants of the algorithm exist which have similar mathematical properties. The most common variant of the CRC32 checksum, sometimes called CRC-32b, is based on the following generator polynomial: g(x) = x 32 + x 26 + x 23 + x 22 + x 16 + x 12 + x 11 + x 10 + x 8 + x 7 + x 5 + x 4 + x 2 + x + 1.

This article only discusses how to write a fast CRC32 algorithm in C/C++. If you aren't too keen on technical details and just want to have the fastest implementation for not-too-small datasets, I strongly recommend using the crc32_fast function. This package implements the crc32c checksum algorithm. It automatically chooses between a hardware-based implementation (using the CRC32C SSE 4.2 instruction of Intel CPUs, and the crc32* instructions on ARMv8 CPUs), or a software-based one when no hardware support can be found.
