KeyAuth is an Open source authentication system with cloud hosting plans as well. Client SDKs available for C#, C++, Python, Java, JavaScript, VB.NET, PHP, Rust, Go, Lua, Ruby, and Perl. KeyAuth has several unique features such as memory streaming, webhook function where you can send requests to API without leaking the API, discord webhook notifications, ban the user securely through the application at your discretion. Feel free to join https://t.me/keyauth if you have questions or suggestions.

Visit https://keyauth.cc/app/ and select your application, then click on the PHP tab

It'll provide you with the code which you should replace with in the credentials.php file.

$KeyAuthApp = new KeyAuth\api("appNameHere", "keyAuthOwnerIDHere");

You must call this function prior to using any other KeyAuth function. Otherwise the other KeyAuth function won't work.

$KeyAuthApp->init();

$numKeys = $_SESSION["numUsers"];
$numUsers = $_SESSION["numKeys"];
$numOnlineUsers = $_SESSION["numOnlineUsers"];
$customerPanelLink = $_SESSION["customerPanelLink"];

if ($KeyAuthApp->login("userNameHere", "passWordHere")) {
  // send user to dashboard or wherever you prefer
}

if ($KeyAuthApp->register("userNameHere", "passWordHere", "licenseKeyHere")) {
  // send user to dashboard or wherever you prefer
}

Used so the user can add extra time to their account by claiming new key.

Warning No password is needed to upgrade account. So, unlike login, register, and license functions - you should not log user in after successful upgrade.

if ($KeyAuthApp->upgrade("userNameHere", "licenseKeyHere")) {
			// don't login, upgrade function is not for authentication, it's simply for redeeming keys
      // make the user login with their username and password now.
}

Users can use this function if their license key has never been used before, and if it has been used before. So if you plan to just allow users to use keys, you can remove the login and register functions from your code.

if ($KeyAuthApp->license("licenseKeyHere")) {
      // send user to dashboard or wherever you prefer
}

Show information for current logged-in user.

$username = $_SESSION["user_data"]["username"];
$subscriptions = $_SESSION["user_data"]["subscriptions"];
$subscription = $_SESSION["user_data"]["subscriptions"][0]->subscription;
$expiry = $_SESSION["user_data"]["subscriptions"][0]->expiry;
for ($i = 0; $i < count($subscriptions); $i++) {
    echo "#" . $i + 1 . " Subscription: " . $subscriptions[$i]->subscription . " - Subscription Expires: " . "<script>document.write(convertTimestamp(" . $subscriptions[$i]->expiry . "));</script>";
}

If you want to wall off parts of your app to only certain users, you can have multiple subscriptions with different names. Then, when you create licenses that correspond to the level of that subscription, users who use those licenses will get a subscription with the name of the subscription that corresponds to the level of the license key they used.

if(findSubscription("default", $_SESSION["user_data"]["subscriptions"])) {
    // user has subscription with name "default"
}
else {
    // user does not have subscription with name "default"
}

A string that is kept on the server-side of KeyAuth. On the dashboard you can choose for each variable to be authenticated (only logged in users can access), or not authenticated (any user can access before login). These are global and static for all users, unlike User Variables which will be dicussed below this section.

//* Get Public Variable
$var = $KeyAuthApp->var("varName");
echo "Variable Data: " . $var;

User variables are strings kept on the server-side of KeyAuth. They are specific to users. They can be set on Dashboard in the Users tab, via SellerAPI, or via your loader using the code below. discord is the user variable name you fetch the user variable by. test#0001 is the variable data you get when fetching the user variable.

//* Set Up User Variable
$KeyAuthApp->setvar("varName", "varData");

And here's how you fetch the user variable:

//* Get User Variable
$var = $KeyAuthApp->getvar("varName");
echo "Variable Data: " . $var;

Can be used to log data. Good for anti-debug alerts and maybe error debugging. If you set Discord webhook in the app settings of the Dashboard, it will send log messages to your Discord webhook rather than store them on site. It's recommended that you set Discord webhook, as logs on site are deleted 1 month after being sent.

You can use the log function before login & after login.

//* Log Something to the KeyAuth webhook that you have set up on app settings
$KeyAuthApp->log("message");

Note Read documentation for KeyAuth webhooks here https://keyauth.readme.io/reference/webhooks-1

Send HTTP requests to URLs securely without leaking the URL in your application. You should definitely use if you want to send requests to SellerAPI from your application, otherwise if you don't use you'll be leaking your seller key to everyone. And then someone can mess up your application.

1st example is how to send request with no POST data. just a GET request to the URL. 7kR0UedlVI is the webhook ID, https://keyauth.win/api/seller/?sellerkey=sellerkeyhere&type=black is what you should put as the webhook endpoint on the dashboard. This is the part you don't want users to see. And then you have &ip=1.1.1.1&hwid=abc in your program code which will be added to the webhook endpoint on the keyauth server and then the request will be sent.

2nd example included post data, JSON. It's an example request to Discord webhook 7kR0UedlVI is the webhook ID, https://discord.com/api/webhooks/... is the webhook endpoint.

$result = $KeyAuthApp->webhook("7kR0UedlVI", "&ip=1.1.1.1&hwid=abc");
echo "<br> Result from Webhook: " . $result;

$result = $KeyAuthApp->webhook("7kR0UedlVI", "", "{\"content\": \"webhook message here\",\"embeds\": null}", "application/json"); // if Discord webhook message successful, response will be empty
echo "<br> Result from Webhook: " . $result;

Ban the user and blacklist their HWID and IP Address.

Function only works after login.

The reason paramater will be the ban reason displayed to the user if they try to login, and visible on the KeyAuth dashboard.

$KeyAuthApp->ban('Broke the rules');
