所以我一直在使用这个登录和注册脚本大约3个项目，它工作得很好。但对于当前的项目，它产生了一些问题。生成的密码与数据库中的密码不匹配，因此无法登录。
注册页面如下：
<?php
include_once 'includes/register.inc.php';
include_once 'includes/functions.php';
?>
<html>
<head>
<meta charset="UTF-8">
<title>Secure Login: Registration Form</title>
<script type="text/JavaScript" src="js/sha512.js"></script>
<script type="text/JavaScript" src="js/forms.js"></script>
<link rel="stylesheet" href="styles/main.css" />
</head>
<body>
<?php
if (!empty($error_msg)) {
echo $error_msg;
}
?>
<form action="<?php echo esc_url($_SERVER['PHP_SELF']); ?>"
method="post"
name="registration_form">
Username: <input type='text'
name='username'
id='username' /><br>
Email: <input type="text" name="email" id="email" /><br>
Password: <input type="password"
name="password"
id="password"/><br>
Confirm password: <input type="password"
name="confirmpwd"
id="confirmpwd" /><br>
<input type="button"
value="Register"
onclick="return regformhash(this.form,
this.form.username,
this.form.email,
this.form.password,
this.form.confirmpwd);" />
</form>
<p>Return to the <a href="index.php">login page</a>.</p>
</body>
</html>
register.inc.php页面如下：
<?php
include_once 'db_connect.php';
include_once 'psl-config.php';
$error_msg = "";
if (isset($_POST['username'], $_POST['email'], $_POST['p'])) {
// Sanitize and validate the data passed in
$username = filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING);
$email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL);
$email = filter_var($email, FILTER_VALIDATE_EMAIL);
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
// Not a valid email
$error_msg .= '<p class="error">The email address you entered is not valid</p>';
}
$password = filter_input(INPUT_POST, 'p', FILTER_SANITIZE_STRING);
if (strlen($password) != 128) {
// The hashed pwd should be 128 characters long.
// If it's not, something really odd has happened
$error_msg .= '<p class="error">Invalid password configuration.</p>';
}
// Username validity and password validity have been checked client side.
// This should should be adequate as nobody gains any advantage from
// breaking these rules.
//
$prep_stmt = "SELECT license_num FROM doctor_details WHERE email = ? LIMIT 1";
$stmt = $mysqli->prepare($prep_stmt);
// check existing email
if ($stmt) {
$stmt->bind_param('s', $email);
$stmt->execute();
$stmt->store_result();
if ($stmt->num_rows == 1) {
// A user with this email address already exists
$error_msg .= '<p class="error">A user with this email address already exists.</p>';
$stmt->close();
}
$stmt->close();
} else {
$error_msg .= '<p class="error">Database error Line 39</p>';
$stmt->close();
}
// check existing username
$prep_stmt = "SELECT license_num FROM doctor_details WHERE username = ? LIMIT 1";
$stmt = $mysqli->prepare($prep_stmt);
if ($stmt) {
$stmt->bind_param('s', $username);
$stmt->execute();
$stmt->store_result();
if ($stmt->num_rows == 1) {
// A user with this username already exists
$error_msg .= '<p class="error">A user with this username already exists</p>';
$stmt->close();
}
$stmt->close();
} else {
$error_msg .= '<p class="error">Database error line 55</p>';
$stmt->close();
}
// TODO:
// We'll also have to account for the situation where the user doesn't have
// rights to do registration, by checking what type of user is attempting to
// perform the operation.
if (empty($error_msg)) {
// Create a random salt
//$random_salt = hash('sha512', uniqid(openssl_random_pseudo_bytes(16), TRUE)); // Did not work
$random_salt = hash('sha512', uniqid(mt_rand(1, mt_getrandmax()), true));
// Create salted password
$password = hash('sha512', $password . $random_salt);
// Insert the new user into the database
if ($insert_stmt = $mysqli->prepare("INSERT INTO doctor_details (username, email, password, salt) VALUES (?, ?, ?, ?)")) {
$insert_stmt->bind_param('ssss', $username, $email, $password, $random_salt);
// Execute the prepared query.
if (! $insert_stmt->execute()) {
header('Location: ../error.php?err=Registration failure: INSERT');
}
}
header('Location: ./register_success.php');
}
}
?>
注册工作正常..并且数据输入到DB。为了说明我已经创建了一个测试记录 email = test@testing.com 密码= Pass123
在DB中输入的密码和Salt
密码：1ca2a523757d457a4df261c647dc45349ca8c721f76fa2b54e
盐：ae2788757a98b0750d0aaecb9735cc27d92d29413cab1c89fb741cf735fd551322f94993b7cb79cd4ade2dea221142dcac7aa380b776db7fa05bf6c6b5d32056
我尝试登录时的哈希密码是
d01feaafb5359e1fa2c020a76ebb526fc75786b0b837e0c9a4dcabd58ad734efa469513cf66a272d5ef4b1b9646b4b39f50807afc8f8663e1c6bb23552b04cd6
登录页面
if (isset($_POST['email'], $_POST['p'])) {
$email = $_POST['email'];
$password = $_POST['p']; // The hashed password.
if (login($email, $password, $mysqli) == true) {
// Login success
header('Location: ../protected_page.php');
} else {
// Login failed
header('Location: ../login.php?error=1');
}
}
登录功能如下
function login($email, $password, $mysqli) {
// Using prepared statements means that SQL injection is not possible.
if ($stmt = $mysqli->prepare("SELECT license_num, username, password, salt
FROM doctor_details
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, $mysqli) == true) {
// Account is locked
// Send an email to user saying their account is locked
return false;
} else {
// Check if the password in the database matches
// the password the user submitted.
if ($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;
// 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')");
return false;
}
}
} else {
// No user exists.
return false;
}
}
}
数据库结构
license_num（主要） 电子邮件 密码 用户名 盐
是因为license_num不是自动增量吗？
谢谢，如果你能提供帮助
