我正在開發一個需要會員資格部分的網站。所以,當用戶註冊一個新的成員帳戶時,我使用隨機salt和用戶密碼保存用戶名,隨機salt和SHA512散列密碼,以便不以純文本形式將密碼保存在我的數據庫中。PHP網站爲桌面和移動瀏覽器返回不同的SHA512值
用戶登錄時似乎存在的問題是,當我從桌面或移動瀏覽器(包括Android和IOS設備)使用網站時,SHA512 JavaScript函數返回的值不同。桌面似乎是正確的。
這裏是我使用來檢查時,在用戶登錄PHP函數:
// login function, check email and password against the database.
function login($email, $password, $mysqli) {
// Using prepared statements means that SQL injection is not possible.
if ($stmt = $mysqli->prepare("SELECT id, username, password, salt
FROM members
WHERE email = ?
LIMIT 1")) {
$stmt->bind_param('s', $email); // Bind "$email" to parameter.
$stmt->execute(); // Execute the prepared query.
$stmt->store_result();
// get variables from result.
$stmt->bind_result($user_id, $username, $db_password, $salt);
$stmt->fetch();
// hash the password with the unique salt.
$password = hash('sha512', $password . $salt);
if ($stmt->num_rows == 1) {
// If the user exists we check if the account is locked
// from too many login attempts
if (checkbrute($user_id, $mysqli) == true) {
// Account is locked
// Send an email to user saying their account is locked
$_SESSION['temp'] = "account locked.";
return false;
} else {
// Check if the password in the database matches
// the password the user submitted.
if ($db_password == $password) {
// Password is correct!
// Get the user-agent string of the user.
$user_browser = $_SERVER['HTTP_USER_AGENT'];
// XSS protection as we might print this value
$user_id = preg_replace("/[^0-9]+/", "", $user_id);
$_SESSION['user_id'] = $user_id;
$_SESSION['temp'] = $user_browser;
// XSS protection as we might print this value
$username = preg_replace("/[^a-zA-Z0-9_\-]+/",
"",
$username);
$_SESSION['username'] = $username;
$_SESSION['login_string'] = hash('sha512',
$password . $user_browser);
// Login successful.
return true;
} else {
// Password is not correct
// We record this attempt in the database
$now = time();
$mysqli->query("INSERT INTO login_attempts(user_id, time)
VALUES ('$user_id', '$now')");
$_SESSION['temp'] = "Invalid password. ";// . $username . " " . $password . " " . $db_password;
return false;
}
}
} else {
$_SESSION['temp'] = "User not Found.";
// No user exists.
return false;
}
}
}
這裏是SHA值我來自同一個用戶名/密碼了: 桌面(這讓我登錄正確):091b2e6cda1e1ee4de89b1164703a238021fa6c092551cfea2c967051bd01f3992dbe160bbc25a14694f119a819b88534b21d0f7c8da9c80bb8c06a79f75074c
從我的Android手機(無效密碼返回):20036264d5fccd56658e45364112ae0e3356878d84150aa817e049a288aa491b88fab9384df71a3aae7e3d0145acd3dc5608030961181b1bf8336e6019824daf

你爲什麼要湊在JavaScript中的密碼,所以最有可能在客戶端?這沒有任何意義。您發送非哈希密碼並將其散列在服務器端!你的哈希算法是一個內部的東西。 – arkascha
