Hey Monks,

I've been trying to check/create a .sfv file (A .sfv file just contain the filename and crc code next to it (in hex) in Perl here... And it should be easy, but the crc32 modules I use dont seem to generate correct crc for binary! (although they say they support files...)
Now, If I create a file called "text.txt" with "Just Anoter Perl Hacker" as content, the following code: 
use String::CRC32;
use Digest::Crc32;

use strict;
use warnings;
use diagnostics;

my $crc32 = new Digest::Crc32();
my $file = "text.txt";

open(SOMEFILE, $file);
my $crc = crc32(*SOMEFILE);
close(SOMEFILE);

print "Dec: " . $crc . "\n";
printf("String::CRC32: %X\n", $crc); # upper case A-F

$crc = $crc32->filecrc32($file);
printf("Digest::Crc32: %X\n", $crc); # upper case A-F

[download]
prints:
Dec: 234160252
String::CRC32: DF5007C
Digest::Crc32: DF5007C

which is correct. If I do the same on a binary though, the crc doesnt match to some 3:rd party .sfv checker/creator (like hKSFV and QuickSFV)...

I would like some help to get this working in Perl!

Thanks,
Ace
