我正在尝试为我的密码正确地执行每个用户和站点范围的盐。这是我所拥有的:
require('../../salt.php'); //this is above the web root and provides $salt variable
$pw = mysql_real_escape_string($_POST['pw']);
$per_user_salt = uniqid(mt_rand());
$site_salt = $salt //from salt.php that was required on first line
$combine = $pw . $per_user_salt . $site_salt;
$pw_to_put_in_db = hash("sha512", $combine);
这是正确的吗?谢谢
