NAME

       String::CRC32 - Perl interface for cyclic redundancy check generation

SYNOPSIS

           use String::CRC32;

           $crc = crc32("some string");
           $crc = crc32("some string", initvalue);

           $somestring = "some string";
           $crc = crc32($somestring);

           open my $fh, '<', 'location/of/some.file' or die $!;
           binmode $fh;
           $crc = crc32($fh);
           close $fh;

DESCRIPTION

       The CRC32 module calculates CRC sums of 32 bit lengths.  It generates the same CRC values
       as ZMODEM, PKZIP, PICCHECK and many others.

       Despite its name, this module is able to compute the checksum of files as well as strings.

EXAMPLES

           $crc = crc32("some string");

       results in the same as

           $crc = crc32(" string", crc32("some"));

       This is useful for subsequent CRC checking of substrings.

       You may even check files:

           open my $fh, '<', 'location/of/some.file' or die $!;
           binmode $fh;
           $crc = crc32($fh);
           close $fh;

       A init value may also have been supplied in the above example.

LICENSE

       CRC algorithm code taken from CRC-32 by Craig Bruce.  The module stuff is inspired by a
       similar perl module called String::CRC by David Sharnoff & Matthew Dillon.  Horst
       Fickenscher told me that it could be useful to supply an init value to the crc checking
       function and so I included this possibility.
