SB-CRC32 Checksum Calculator  SB-CRC32 Checksum Calculator - Freeware

SB-CRC32 Checksum Calculator is a tool to calculate and compare the CRC32 checksum of files.  CRC32  is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents; on retrieval the calculation is repeated, and corrective action can be taken against presumed data corruption if the check values do not match.

How to use SB-CRC32 Checksum Calculator.

  1. Press the Browse button.  This will allow to to select a file:

SB-CRC32 Result



You will notice in the CRC32 field the value 6e17a15e  This is the CRC32 checksum value.

2.  I can compare the CRC32 checksum value with another file to see if they are the same.  Press the Compare button this will allow you to select a file to compare with:

SB-CRC32 Open File


In this case I will use Capture.PNG

SB-CRC32 Files Match

You will notice that CRC32 checksum value of the file I just selected turned green.  This indicates that the files are the same.  If I were to select a file that was slightly different, it would have turned red:

SB-CRC32 Files don’t Match

If I happened to copy to the clipboard an CRC32 value, SB-CRC32 will automatically check if the CRC32 values are the same with the first file you selected:
