http://www.ghsi.de/pages/subpages/Online%20CRC%20Calculation/ WebA cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.

WebApr 20, 2024 · That CRC-32 is commonly referred to as the CRC-32C (where outside the provided code the initial value and final exclusive-or is 0xffffffff). There are two errors in your code. The table must be 32-bit values, and the initial value for your CRCs is zero. So you need uint32_t kCrc32tab[256]; and kCrc32tab[i] = calculateCrc32(0, &buf, 1);.
