什么类型的散列?(md5，sha1）.对于PassHash sha1和Secret(可能是salt）md5 ATR，

我已经在尝试许多哈希算法（使用hashcat）但没有结果。。

if ($_SERVER["REQUEST_METHOD"] == "POST")
{
    if ($_POST["username"] == "" || $_POST["password"] == "" || $_POST["email"] == "")
        stderr("Error", "Missing form data.");
    if ($_POST["password"] != $_POST["password2"])
        stderr("Error", "Passwords mismatch.");
    if (!validemail($_POST['email']))
        stderr("Error", "Not valid email");
    $username = sqlesc($_POST["username"]);
    $password = $_POST["password"];
    $email = sqlesc($_POST["email"]);
    $secret = mksecret();
    $passhash = sqlesc(md5($secret . $password . $secret));
    $secret = sqlesc($secret);
    mysql_query("INSERT INTO users (added, last_access, secret, username, passhash, status, email) VALUES(NOW(), NOW(), $secret, $username, $passhash, 'confirmed', $email)") or sqlerr(__FILE__, __LINE__);
    $res = mysql_query("SELECT id FROM users WHERE username=$username");
    $arr = mysql_fetch_row($res);
    if (!$arr)
        stderr("Error", "Unable to create the account. The user name is possibly already taken.");
    header("Location: $BASEURL/userdetails.php?id=$arr[0]");
    die;
}

这是什么类型的散列？
