php - PHP 的 MySQL password() 函数

Question

我尝试对此进行研究，但仍然没有答案。我 friend 设计的程序使用 MySQL password() 函数将密码写入 MySQL 数据库。

我正在寻找一种通过我设计的 Web 前端使用它的方法，但仍然没有运气。有人有什么建议吗？

密码看起来就像这个例子

mysql> SET old_passwords = 0;
mysql> SELECT PASSWORD('mypass');
+-------------------------------------------+
| PASSWORD('mypass')                        |
+-------------------------------------------+
| *6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4 |
+-------------------------------------------+

我只需要弄清楚如何将它变成一个函数，即 函数密码哈希

下面是示例的登录查询

if (isset($_POST["username"], $_POST["password"], $_POST[$CONF["LOGIN_SIGNAL_TRIGGER"]])) {

    /*
        If we got a login signal, a password and a username, we will
        proceed to check login information. We will first extract
        the user row from the db.
    */
    $user = myF(myQ("
        SELECT `username`,`password`,`id`,`disable_until`,`active`
        FROM `[x]users` 
        WHERE LCASE(`username`)='".strtolower($_POST["username"])."'
    "));

    if (!$user["id"]) $GLOBALS["LOGIN_FAIL_TYPE"] = "e.user";
    elseif ($user["active"] != 1 && $CONF["LOGIN_REQUIRE_ACTIVE"]) $GLOBALS["LOGIN_FAIL_TYPE"] = "e.active";

    else {
        /*
            If the user's account 'disabled' value is greater than 
            the actual date value, and that the bruteforce protection
            system is enabled, we will show an error message
        */
        if (($user["disable_until"] > date("U")) && ($CONF["LOGIN_BRUTEFORCE_PROTECT:ENABLE"])) {
             $GLOBALS["LOGIN_FAIL_TYPE"] = "e.bruteforce";
            (isset($_SESSION["loginFailCount"])?session_unregister('loginFailCount'):false);
        }

        /*
            Account is not disabled
        */
        else {
            if ((isset($_SESSION["loginFailCount"])) && ($_SESSION["loginFailCount"] > $CONF["LOGIN_BRUTEFORCE_FAILCOUNT"])) {

                myQ("UPDATE `[x]users`
                    SET `disable_until` = ".(date("U")+$CONF["LOGIN_BRUTEFORCE_DISABLE_DURATION"])."
                    WHERE LCASE(`username`)='".strtolower($_POST["username"])."'
                    LIMIT 1"
                );

                (isset($_SESSION["loginFailCount"])?session_unregister('loginFailCount'):false);
                $GLOBALS["LOGIN_FAIL_TYPE"] = "e.bruteforce";
            }

            else {

                /*
                    All the information correct, we will proceed to login
                */
                if ($user["password"] == md5(trim($_POST["password"]))) {
                    $_SESSION["id"] = (integer)$user["id"];

                    session_write_close();

                    /*
                        Update the last login key
                    */
                    $me_last_login = me("last_login");
                    myQ("UPDATE `[x]users` SET `last_login`='".date("U")."' WHERE `id`='".me('id')."'");

                    /*
                        Route the user
                    */
                    if (!$GLOBALS["WAP_MODE"]) {
                        header("Location: ".(!$me_last_login?$CONF["LOGIN_FIRST_ROUTE_TO"]:$CONF["LOGIN_ROUTE_TO"]));
                    } else header("Location: {$CONF["WAP_LOGIN_ROUTE_TO"]}");

                } 

                else {
                    (isset($_SESSION["loginFailCount"])?$_SESSION["loginFailCount"]++:$_SESSION["loginFailCount"]=1);
                    $GLOBALS["LOGIN_FAIL_TYPE"] = "e.password";
                }
            }
        }
    }
}

if ((isset($_GET[$CONF["LOGOUT_SIGNAL_TRIGGER"]])) && (!isset($_POST[$CONF["LOGIN_SIGNAL_TRIGGER"]]))) {

    /*
        Handle admin swapping
    */
    if (isset($_SESSION["swap_id"])) {
        $_SESSION["id"] = $_SESSION["swap_id"];
        session_unregister("swap_id");
        header("Location: ?L=admin.index");
    }

    else {
        (isset($_SESSION["id"])?session_unregister('id'):false);
        (isset($_SESSION["SELF_USER_DATA"])?session_unregister('SELF_USER_DATA'):false);

        header("Location: {$CONF["LOGOUT_ROUTE_TO"]}");
    }
}

Answer 1

OP 询问如何在 php 中执行此操作。这是在 php 中的实现方式:

function sqlPassword($input) {
    $pass = strtoupper(
            sha1(
                    sha1($input, true)
            )
    );
    $pass = '*' . $pass;
    return $pass;
}

为后代添加(没有理由你会使用它，如果 mysql 决定弃用 PASSWORD 函数，请使用它？仅供引用)php 等价物的 mysql 等价物

SELECT 
  UPPER(
    CONCAT('*', SHA1(UNHEX(SHA1('password'))))
  )
