Checksum method

Post by HeeA »

Hi Dear,

How does CRC-32 work? Does it work like the formula below? If not, please explain how it works.
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

Thanks,
Maël

Sorry for the late reply, I was away.

It corresponds to CRC-32
04C11DB7
<crc-32>
as found under:
http://protocoltool.sourceforge.net/CRC%20list.html

The source code is not related, but they should produce the same results.

Or see the CRC-32 entry here (polynomial 0x04C11DB7):
