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. Features: Calculate CRC32 checksum of a file.Compare CRC32 checksum of two files.Copy CRC32 hash to Windows clipboard.Compare value from the clipboard with CRC32 checksum of a file.
