## NAME
       crc32 - compute CRC-32 checksums for the given files

## SYNOPSIS
       **crc32** _filename_ [ _filename_ ... ]

## DESCRIPTION
       **crc32** is a simple utility that calculates the CRC-32 checksum for each of the given files.

       Note that the CRC-32 checksum is merely used for error detection in transmission and storage.
       It is not intended to guard against the malicious modification of files (i.e., it  is  not  a
       cryptographic hash).

       This utility is supplied with the [**Archive::Zip**](https://www.chedong.com/phpMan.php/perldoc/Archive%3A%3AZip/markdown) module for Perl.
