CRC32 Static Library for Microsoft VC++ was produced to make your CRC checking operations quick & lenient to implement seamlessly without the motivation for an external DLL
The CRC is a "digital fingerprint" of a file, With CRC32 you stern "melting down" a huge 20 MB (or even much bigger) file to deliver a little, handy denotation to it, a single 32-bit numerate like 7d9c42fb (hexadecimal notation) which would unambiguously reflect the entire contents of this huge file. Now if some changes to this file happened, no weigh how little, maybe only a single wrong chip somewhere in the middle, a freshly CRC-32 reckoning would render a altogether different denotation numerate (pronounce 3faa83bd). So there'd be no incertitude about it - this is not the same file anymore. On the other pass if the denotation numerate was even the same (7d9c42fb) you might be indisputable that the file hasn't changed.
The algorithm of CRC32 is exactly the same as that internally used by PKZIP and WinZip; i.e. the CRCs calculated by PKZIP and CRC32 are identical. That's another fine thing about CRC32 - it calculates compatible, widely used 32-bit checksums, not just any numbers. You stern practice the 'pkunzip.exe -vt filename.zip' require to project that PKZIP's CRC-32 values of files stored inwardly the filename.zip are identical to that calculated by CRC32 for these files.
Though you stern practice CRC32 to reckon 32-bit checksums of any file the real lastingness and usefulness of CRC32 is in comparing Wave Sound Files to project if their non-silent music parts are identical. In finical CRC32 may come in handy when comparing two different extractions of a CD Digital Audio cut to insure that the performed digital copy is perfect.
