You can install the libary via composer:
composer require laizerox/php-wowemu-authFirst you'll want to use Composer's autoloader. Place this at the top of your script.
require_once __DIR__ . '/vendor/autoload.php';
use Laizerox\Wowemu\SRP\UserClient;Next you'll need to create the verifier and salt values using the username and password which your user submitted on your registration form.
$client = new UserClient($username);
$salt = $client->generateSalt();
$verifier = $client->generateVerifier($password);Once that is generated you'll just insert those values into the database to the v and s fields.
First you'll want to use Composer's autoloader. Place this at the top of your script.
require_once __DIR__ . '/vendor/autoload.php';
use Laizerox\Wowemu\SRP\UserClient;Next you'll need to generate your "verifier". Think of this as the hashed version of the password your user put into the password field of you login form.
$client = new UserClient($username, $saltFromDatabase);
$verifier = strtoupper($client->generateVerifier($password));Next you'll want to compare that value with the value stored in your CMaNGOS realmd.account table. You can see below for more of an example.
This example goes over how a user can register via a web form.
<?php
/* register.php */
require_once __DIR__ . '/vendor/autoload.php';
use Laizerox\Wowemu\SRP\UserClient;
/* Connect to your CMaNGOS database. */
$db = new mysqli($dbHost, $dbUser, $dbPassword, $dbName);
/* If the form has been submitted. */
if (isset($_POST['register'])) {
$username = $_POST['username'];
$password = $_POST['password'];
/* Grab the users IP address. */
$ip = $_SERVER['REMOTE_ADDR'];
/* Set the join date. */
$joinDate = date('Y-m-d H:i:s');
/* Set GM Level. */
$gmLevel = '0';
/* Set expansion pack - Wrath of the Lich King. */
$expansion = '2';
/* Create your v and s values. */
$client = new UserClient($username);
$salt = $client->generateSalt();
$verifier = $client->generateVerifier($password);
/* Insert the data into the CMaNGOS database. */
mysqli_query($db, "INSERT INTO account (username, v, s, gmlevel, email, joindate, last_ip, expansion) VALUES ('$username', '$verifier', '$salt', '$gmLevel', '$email', '$joinDate', '$ip', '$expansion')");
/* Do some stuff to let the user know it was a successful or unsuccessful attempt. */
}
?>Now you'll obviously want to do some error checking and validation, but we'll leave that up to you.
<form action="/register" method="post">
<input type="text" name="username" placeholder="Username">
<input type="email" name="email" placeholder="Email Address">
<input type="password" name="password" placeholder="Password">
<?php $register = sha1(time()); ?>
<input type="hidden" name="register" value="<?php echo $register; ?>">
<button type="submit">Register</button>
</form>The above is a very basic HTML form for user registrations.
<?php
/* login.php */
require_once __DIR__ . '/vendor/autoload.php';
use Laizerox\Wowemu\SRP\UserClient;
/* Connect to your CMaNGOS database. */
$db = new mysqli($dbHost, $dbUser, $dbPassword, $dbName);
/* Function to get values from MySQL. */
function getMySQLResult($query) {
global $db;
return $db->query($query)->fetch_object();
}
/* If the form has been submitted. */
if (isset($_POST['login'])) {
$username = $_POST['username'];
$password = $_POST['password'];
/* Get the salt and verifier from realmd.account for the user. */
$query = "SELECT s,v FROM account WHERE username='$username'";
$result = getMySQLResult($query);
$saltFromDatabase = $result->s;
$verifierFromDatabase = strtoupper($result->v);
/* Setup your client and verifier values. */
$client = new UserClient($username, $saltFromDatabase);
$verifier = strtoupper($client->generateVerifier($password));
/* Compare $verifierFromDatabase and $verifier. */
if ($verifierFromDatabase === $verifier) {
/* Do your login stuff here, like setting cookies/sessions... */
}
else {
/* Do whatever you wanna do when the login has failed, send a failure message, redirect them to another page, etc... */
}
?>Again, you'll want to add in your own error checking and validation but this should get you started.
<form action="/login" method="post">
<input type="text" name="username" placeholder="Username">
<input type="password" name="password" placeholder="Password">
<?php $login = sha1(time()); ?>
<input type="hidden" name="login" value="<?php echo $login; ?>">
<button type="submit">Sign In</button>
</form>The above is a very basic HTML form for user logins.
