# crc32(1)

compute CRC-32 checksums for the given files

## 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** module for Perl.
