Description:
------------
I have made a simple hashing function and it returns bad value!
Reproduce code:
---------------
function hash ($MAIL, $PASS)
{
//$amail = str_split($MAIL);
//$apass = str_split($PASS);
$mdl=strlen($MAIL);
for($z=0;$z<$mdl;$z++)
{
$amail[$z] = $MAIL{$z};
}
$pdl=strlen($PASS);
for($z=0;$z<$pdl;$z++)
{
$apass[$z] = $PASS{$z};
}
$tab = array_merge($apass, $amail);
$b = -1;
$i=0;
while( ($c = ord($tab[$i++])) != '' )
{
$a = ($c ^ $b) + ($c << 8);
$b = ($a >> 24) | ($a << 8);
}
return ($b < 0 ? -$b : $b);
}
$m = "[EMAIL PROTECTED]";
$p = "testpass";
$fun = hash($m, $p);
Expected result:
----------------
on 3rd or 4th value of calculating hash everything go down ... there is
very small number eg. -16 or sommething but there should be a huge one...
like -4168570667... dudes what to do ??
Actual result:
--------------
best regards :)
