Why will this not work? 
use LWP::UserAgent;
use Digest::SHA1  qw(sha1 sha1_hex sha1_base64);

 
$sourcekey = 'K123456789L';
$pin = '1234';
$command = 'cc:sale';
$amount = '5.50';
$invoice = '123123';
 
# Generate Hash
$seed = rand();
$prehash = $command . ":" . $pin . ":" . $amount . ":" . $invoice . ":
+" . $seed;
$hash = 's/' . $seed . '/' . sha1_hex($prehash) . '/n';

The says it is not the same as sent, meaning it did not work any help would be greatly appreciated
