Installation

Install via Composer:

composer require muradcade/secureauth

Validation

SecureAuth wraps Laravel’s validation components for simple and robust validation.

Validation Usage

use SecureAuth\Security\Csrf;
use SecureAuth\Validation\Validator;
use SecureAuth\Validation\ValidatorMessages;

// Create Validator instance
$validator = new Validator();
// custom validation message
 $customErrorMessage = new ValidatorMessages($validator);
 // if there is no csrf token generate one   = Csrf::generateToken();
$token = Csrf::getToken(); // get the generated session


// Data to validate
$data = [
    'email' => '[e-mail]',
    'password' => 'StrongPass123!',
    'csrf_token' => $token
];

// Validation rules
$rules = [
    'email' => 'required|email',
    'password' => 'required|min:8|strong_password',
    'csrf_token' => 'required|verify_csrftoken'
];

// Validate and handle errors
if (!$validator->validate($data, $rules, $customErrorMessage->validationMessage())) {
    var_dump($validator->errors()[0]);
}

Validation Rules

Rule	Description
required	Field must not be empty
email	Must be a valid email format
min:8	Minimum 8 characters
strong_password	Must include uppercase, lowercase, numbers, and symbols
verify_csrftoken	Validates that the CSRF token is valid

BaseRepository

Provides database interaction using prepared statements with MySQLi.

BaseRepository Usage

use SecureAuth\Repository\BaseRepository;

// Pass a MySQLi connection
$repository = new BaseRepository($connection);

// Insert a new user
$repository->query(
    'INSERT INTO users(fullname,email,password) VALUES (?, ?, ?)',
    'sss',
    $data['fullname'],
    $data['email'],
    password_hash($data['password'], PASSWORD_DEFAULT)
);

• Supports SELECT, INSERT, UPDATE, DELETE operations.

Authentication

Authenticate users with database data and manage sessions.

Authentication Usage

use SecureAuth\Auth\Auth;
use SecureAuth\Auth\SessionHelper;
use SecureAuth\Repository\BaseRepository;

// Fetch user record
$result = $repository
    ->query('SELECT * FROM users WHERE email = ?', 's', $data['email'])
    ->fetchOne();

// Authenticate user
if (Auth::authenticateUser($result, $data['email'], $data['password'])) {
    SessionHelper::setUserSession($result['fullname'], $result['email'], $result['userrole'], $result['id']);
    header('Location: dashboard.php');
    exit();
}

Authorization

Check user login status and role-based access.

Authorization Usage

use SecureAuth\Auth\Authorization;
use SecureAuth\Auth\SessionHelper;

$auth = new Authorization();

// Redirect if user is logged in (e.g., login page)
$auth->Islogedin(SessionHelper::getSessionVariable('username'), 'dashboard.php');

// Redirect if user is not logged in
$auth->Isnotlogedin(SessionHelper::getSessionVariable('username'), 'index.php');

// Authorize specific user roles
$auth->AuthorizedUser(SessionHelper::getSessionVariable('userrole'), 'admin', 'index.php');

Email Jobs

Supports sending emails with or without attachments using a worker-job system.

Job Structure

• JobInterface – Defines rules for processing email jobs.
  
• EmailJob – Handles sending emails.
  
• WorkerJob – Dispatches email jobs.
  

Email Jobs Usage

use SecureAuth\Jobs\WorkerJob;
use SecureAuth\Jobs\EmailJob;

$mailContent = [
    'to' => '[e-mail]',
    'subject' => 'Test Email',
    'body' => '<h1>Hello World</h1>',
    'attachment' => __DIR__ . '/files/test.txt' // optional
];

// Dispatch job (emailjobclass) , $config comes from env file and mailcontent is array above
$result = WorkerJob::run(EmailJob::class, $config, $mailContent);

RememberMe Token

Manages persistent login tokens stored in cookies.

RememberMe Token Usage

use SecureAuth\Security\RememberMeToken;
use SecureAuth\Auth\Authorization;
use SecureAuth\Auth\SessionHelper;

$tokenManager = new RememberMeToken();

// Generate token and set cookie
$tokenManager->generateRememberMeToken()->setCookie();
// create instance of authorization class
$auth = new Authorization();
// Check if session missing but token exists
if ($auth->shouldRotateToken(SessionHelper::getSessionVariable('userid'), $tokenManager->getTokenContent())) {
    $tokenManager->rotateTokenContent();
    SessionHelper::setUserSession('Username', '[e-mail]', 'role', 2);
} else {
    $auth->redirectIfNotLoggedIn(SessionHelper::getSessionVariable('userid'), 'index.php', $tokenManager->getTokenContent());
}

// Get current token
$currentToken = $tokenManager->getTokenContent();

Environment Configuration

$config = [
    'DATABASE' => [
        'hostname' => 'localhost',
        'username' => 'root',
        'password' => '',
        'dbname' => 'secureauth'
    ],
    'MAIL' => [
        'GOOGLE_EMAIL' => '[e-mail]',
        'GOOGLE_SECRET_KEY' => '',
        'PROJECT_NAME' => 'TEST',
        'Email_Verification_Url' => 'http://localhost/secureauth/'
    ]
];

Rate Limiter

The Rate Limiter is responsible for preventing brute-force login attacks by limiting the number of failed login attempts a user can make within a specified timeframe. It works by storing failed attempts in a database table and checking whether the threshold has been exceeded before processing further login requests.

Database Schema

Before using the Rate Limiter, create the login_attempts table:

CREATE TABLE login_attempts (
    id INT(4) PRIMARY KEY AUTO_INCREMENT,
    ip VARCHAR(45) NOT NULL,
    email VARCHAR(255) NOT NULL,
    attempt_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

How It Works

1. Store Failed Attempts : Every time a login attempt fails (invalid email or password), an entry is stored in the login_attempts table.
   
2. Check Attempt Limits:Before processing a new login, the RateLimiter checks if the IP/email combination has exceeded the maximum allowed attempts in the defined interval.
   
3. Block Excessive Attempts: If the limit is reached, the login is denied. The user must wait until the retry window has expired before attempting again.
   
4. Reset After Success:On successful login, all attempts for that user/email are cleared.

Example Usage

Below is how you integrate the RateLimiter inside your login controller or login handler:

use SecureAuth\Security\RateLimiter;

// Get client IP
$ip = $_SERVER['REMOTE_ADDR'] ?? 'unknown';

// 1. Store failed attempt
$baserepo->query(
    'INSERT INTO login_attempts(ip, email) VALUES(?, ?)',
    'ss',
    $ip,
    $email
);

// 2. Check if too many attempts
if ($rateLimiter->tooManyAttempts($ip, $email)) {
    $retryAfter = $rateLimiter->getRetryAfterSeconds($ip, $email);
    header('Retry-After: ' . $retryAfter);

    // Optionally send correct HTTP code (for APIs)
    // http_response_code(429);

    // Store error in session (for UI feedback)
    SessionHelper::flash('error', 'Too many login attempts. Please wait ' . $retryAfter . ' seconds.');

    header('location:index.php');
    exit();
}

Example Workflow

Here’s how everything ties together in a login flow:
Login Page (index.php)

<?php if ($msg = SessionHelper::getFlash('error')): ?>
    <p style="color:red"><?= htmlspecialchars($msg); ?></p>
<?php endif; ?>

<form method="POST">
    <input type="hidden" name="csrf_token" value="<?= htmlspecialchars($token, ENT_QUOTES, 'UTF-8') ?>">
    <input type="text" name="email" placeholder="email">
    <br><br>
    <input type="password" name="password" placeholder="password">
    <br><br>
    <label>
        <input type="checkbox" name="remember_me"> Remember Me
    </label>
    <br><br>
    <button type="submit" name="submit">Login</button>
</form>

Login Logic

This file handles:

1. Input validation
2. CSRF token generation & validation
3. Rate limiting
4. User authentication
5. Remember Me functionality

if ($rateLimiter->tooManyAttempts($ip, $email)) {
    $retryAfter = $rateLimiter->getRetryAfterSeconds($ip, $email);
    SessionHelper::flash('error', "Too many login attempts. Please wait {$retryAfter} seconds.");
    header('location:index.php');
    exit();
}

$result = $baserepo->query(
    'SELECT * FROM users WHERE email = ?',
    's',
    $email
)->fetchOne();

if ($result && Auth::AuthenticateUser($result, $email, $password)) {
    $baserepo->query('DELETE FROM login_attempts WHERE email = ?', 's', $email);
    // set session, regenerate CSRF, handle Remember Me, redirect
} else {
    $baserepo->query('INSERT INTO login_attempts(ip, email) VALUES(?, ?)', 'ss', $ip, $email);
    SessionHelper::flash('error', 'Invalid email or password');
    header('location:index.php');
    exit();
}
