crc32 filename [ filename ... ]
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.
The Archive::Zip module was written by Ned Konz. This manual page was prepared by Ben Burton <email@example.com> for the Debian GNU/Linux system (but may be used by others).
