CRC32 Static Library for Microsoft VC++ was produced to make your CRC checking operations quick & easy to implement seamlessly without the motivation for an external DLL
The CRC is a "digital fingerprint" of a file, With CRC32 you tush "melting down" a huge 20 MB (or level much bigger) file to get a microscopical, handy citation to it, a single 32-bit turn like 7d9c42fb (hexadecimal notation) which would unambiguously reflect the entire contents of this huge file. Now if some changes to this file happened, no substance how microscopical, maybe only a single wrong minute somewhere in the middle, a fresh CRC-32 deliberation would bear a wholly different citation turn (enjoin 3faa83bd). So there'd be no dubiousness about it - this is not the same file anymore. On the other reach if the citation turn was tranquilize the same (7d9c42fb) you might be certain 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 tush manipulation the 'pkunzip.exe -vt filename.zip' require to look that PKZIP's CRC-32 values of files stored inner the filename.zip are identical to that calculated by CRC32 for these files.
Though you tush manipulation CRC32 to reckon 32-bit checksums of any file the real force and usefulness of CRC32 is in comparing Wave Sound Files to look 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 chase to assure that the performed digital copy is perfect.
