将安全措施嵌入到用户身份验证中对于保护敏感信息至关重要。加盐密码可增强加密并防止未经授权的访问。本文讨论针对数据库验证加盐密码并确保用户授权的过程。
验证加盐密码
要验证加盐密码,我们按照以下步骤操作:
加盐密码验证示例代码:
$servername = 'localhost'; $username = 'root'; $pwd = ''; $dbname = 'lp001'; $connect = new mysqli($servername, $username, $pwd, $dbname); if ($connect->connect_error) { die('Connection failed: ' . $connect->connect_error); } $name = mysqli_real_escape_string($connect, $_POST['name']); $password = mysqli_real_escape_string($connect, $_POST['password']); $saltQuery = "SELECT salt FROM users WHERE name = '$name';"; $saltResult = mysqli_query($connect, $saltQuery); if ($saltResult === false) { die(mysqli_error($connect)); } $row = mysqli_fetch_assoc($saltResult); $salt = $row['salt']; $saltedPW = $password . $salt; $hashedPW = hash('sha256', $saltedPW); $sqlQuery = "SELECT * FROM users WHERE name = '$name' AND password = '$hashedPW';"; $sqlResult = mysqli_query($connect, $sqlQuery); if (mysqli_query($connect, $sqlQuery)) { echo '<h1>Welcome to the member site ' . $name . '</h1>'; } else { echo 'Error adding the query: ' . $sqlQuery . '<br> Reason: ' . mysqli_error($connect); }
将这些步骤和示例代码合并到您的会员中网站,您可以有效验证加盐密码,确保安全高效的用户授权。
