Advanced File Calculator is a cryptographic data hash calculation software for files. Simply drag and drop files in this calculator and hash string for the files will be displayed on the fly. Supported cryptographic hash calculation algorithms include CRC32 control sum, GOST hash, MD2, MD4, MD5, SHA-1, HA2 (256), SHA2 (384), SHA2 (512). You may copy separate hash string corresponding to the file contents data or export them in to text file for future use. This software is capable of up to 1000 concurent hash calculations. Webmasters can also benefot from this utility to calculate and place MD5 hash strings values on their website to verify the integrity of the data.

CRC32 Static Library for Microsoft VC++ was produced to make your CRC checking operations quick & easy to implement seamlessly without the need for an external DLL

The CRC is a "digital fingerprint" of a file, With CRC32 you can "melt down" a huge 20 MB (or even much bigger) file to have a small, handy reference to it, a single 32-bit number like 7d9c42fb (hexadecimal notation) which would unambiguously reflect the entire contents of this huge file. Now if some changes to this file happened, no matter how small, maybe only a single wrong bit somewhere in the middle, a new CRC-32 calculation would yield a completely different reference number (say 3faa83bd). So there’d be no doubt about it - this is not the same file anymore. On the other hand if the reference number was still the same (7d9c42fb) you might be sure 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 can use the 'pkunzip.exe -vt filename.zip' command to see that PKZIP’s CRC-32 values of files stored inside the filename.zip are identical to that calculated by CRC32 for these files.

Though you can use CRC32 to calculate 32-bit checksums of any file the real strength and usefulness of CRC32 is in comparing Wave Sound Files to see if their non-silent music parts are identical. In particular CRC32 may come in handy when comparing two different extractions of a CD Digital Audio track to ensure that the performed digital copy is perfect.

SFV Checker uses CRC-32 technology to check each file and notifies you of any potentially bad, corrupt, incorrect size or missing files to save you hours of downloading only to find you have 1 file missing or the last file has a CRC checksum error.
The CRC value comparison is done by using a standard SFV file. If an SFV file is not available, you can drag and drop the file into the list view to produce the calculated CRC value. An informative report log is generated after file scanning that provides a list of missing and inconsistent files, as well as, a summary for the archive.
SFV Checker can also concatenate files in the list and rename multi archives on the fly, e.g. Correct file naming for .001, .002, .003 files into .rar, .r00, r01 files.
SFV Checker supports RAR, ARJ, ACE and ALL other Binary/Text file types.
