KeyAuth C# example for the https://keyauth.cc authentication system.
If the default example not added to your software isn't functioning how it should, please report a bug here https://keyauth.cc/app/?page=forms
However, we do NOT provide support for adding KeyAuth to your project. If you can't figure this out you should use Google or YouTube to learn more about the programming language you want to sell a program in.

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.
This is common amongst all authentication systems. Program obfuscation causes false positives in virus scanners, and with the scale of KeyAuth this is perceived as a malicious domain. So, keyauth.com and keyauth.win have been blocked by many internet providers. for dashbord, reseller panel, customer panel, use keyauth.cc
For API, keyauth.cc will not work because I purposefully blocked it on there so keyauth.cc doesn't get blocked also. So, you should create your own domain and follow this tutorial video https://www.youtube.com/watch?v=a2SROFJ0eYc. The tutorial video shows you how to create a domain name for 100% free if you don't want to purchase one.
Visit https://keyauth.cc/app/ and select your application, then click on the C# tab
It'll provide you with the code which you should replace with in the Program.cs file (or Login.cs file if using Form example)
public static api KeyAuthApp = new api(
name: "example",
ownerid: "JjPMBVlIOd",
secret: "db40d586f4b189e04e5c18c3c94b7e72221be3f6551995adc05236948d1762bc",
version: "1.0"
);You must call this function prior to using any other KeyAuth function. Otherwise the other KeyAuth function won't work.
KeyAuthApp.init();
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}KeyAuthApp.fetchStats();
Console.WriteLine("\n Application Version: " + KeyAuthApp.app_data.version);
Console.WriteLine(" Customer panel link: " + KeyAuthApp.app_data.customerPanelLink);
Console.WriteLine(" Number of users: " + KeyAuthApp.app_data.numUsers);
Console.WriteLine(" Number of online users: " + KeyAuthApp.app_data.numOnlineUsers);
Console.WriteLine(" Number of keys: " + KeyAuthApp.app_data.numKeys);Use this to see if the user is logged in or not.
KeyAuthApp.check();
Console.WriteLine($" Current Session Validation Status: {KeyAuthApp.response.message}");Check if HWID or IP Address is blacklisted. You can add this if you want, just to make sure nobody can open your program for less than a second if they're blacklisted. Though, if you don't mind a blacklisted user having the program for a few seconds until they try to login and register, and you care about having the quickest program for your users, you shouldn't use this function then. If a blacklisted user tries to login/register, the KeyAuth server will check if they're blacklisted and deny entry if so. So the check blacklist function is just auxiliary function that's optional.
if(KeyAuthApp.checkblack()) {
Environment.Exit(0); // terminate program if user blacklisted.
}string username;
string password;
Console.WriteLine("\n\n Enter username: ");
username = Console.ReadLine();
Console.WriteLine("\n\n Enter password: ");
password = Console.ReadLine();
KeyAuthApp.login(username, password);

Console.Write("\n\n Enter email (just press enter if none): ");

KeyAuthApp.register(username, password, key, email);
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}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.
string username;
string password;
string key;
Console.WriteLine("\n\n Enter username: ");
username = Console.ReadLine();
Console.WriteLine("\n\n Enter license: ");
key = Console.ReadLine();
KeyAuthApp.upgrade(username, key);
// don't proceed to app, user hasn't authenticated yet.
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
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.
string key;
Console.WriteLine("\n\n Enter license: ");
key = Console.ReadLine();
KeyAuthApp.license(key);
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}Have your users login through website. Tutorial video here https://www.youtube.com/watch?v=9-qgmsUUCK4 you can use your own domain for customer panel also, https://www.youtube.com/watch?v=iHQe4GLvgaE
KeyAuthApp.web_login();
Console.WriteLine("\n Waiting for button to be clicked");
KeyAuthApp.button("close");Allow users to enter their account information and recieve an email to reset their password.

Console.Write("\n\n Enter email: ");
email = Console.ReadLine();
KeyAuthApp.forgot(username, email);
// don't proceed to app, user hasn't authenticated yet.
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);Show information for current logged-in user.

}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. The SubExist function is in the Program.cs file
if (SubExist("default"))
{
Console.WriteLine(" Default Subscription Exists");
}
// See if another sub exists with name
if (SubExist("premium"))
{
Console.WriteLine(" Premium Subscription Exists");
}var onlineUsers = KeyAuthApp.fetchOnline();
if (onlineUsers != null)
{
Console.Write("\n Online users: ");
foreach (var user in onlineUsers)
{
Console.Write(user.credential + ", ");
}
Console.WriteLine("\n");
}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.
string appvar = KeyAuthApp.var("variableNameHere");
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}
else
Console.WriteLine("\n App variable data: " + appvar);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.
KeyAuthApp.setvar("discord", "test#0001");
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}
else
Console.WriteLine("\n Successfully set user variable");And here's how you fetch the user variable:
string uservar = KeyAuthApp.getvar("discord");
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}
else
Console.WriteLine("\n User variable value: " + uservar);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.
KeyAuthApp.log("hello I wanted to log this");Ban the user and blacklist their HWID and IP Address. Good function to call upon if you use anti-debug and have detected an intrusion attempt.
Function only works after login.
KeyAuthApp.ban();Ban the user and blacklist their HWID and IP Address. Good function to call upon if you use anti-debug and have detected an intrusion attempt.
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("You've been banned for a reason.");Tutorial video https://www.youtube.com/watch?v=ENRaNPPYJbc
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 includes post data. it is form data. it is an example request to the KeyAuth API. 7kR0UedlVI is the webhook ID, https://keyauth.win/api/1.2/ is the webhook endpoint.
3rd examples included post data though it's JSON. It's an example reques to Discord webhook 7kR0UedlVI is the webhook ID, https://discord.com/api/webhooks/... is the webhook endpoint.
// example to send normal request with no POST data
string resp = KeyAuthApp.webhook("7kR0UedlVI", "&ip=1.1.1.1&hwid=abc");
// example to send form data
resp = KeyAuthApp.webhook("7kR0UedlVI", "", "type=init&name=test&ownerid=j9Gj0FTemM", "application/x-www-form-urlencoded");
// example to send JSON
resp = KeyAuthApp.webhook("7kR0UedlVI", "", "{\"content\": \"webhook message here\",\"embeds\": null}", "application/json"); // if Discord webhook message successful, response will be empty
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}
else
Console.WriteLine("\n Response received from webhook request: " + resp);Note Read documentation for KeyAuth files here https://docs.keyauth.cc/website/dashboard/files
Keep files secure by providing KeyAuth your file download link on the KeyAuth dashboard. Make sure this is a direct download link (as soon as you go to the link, it starts downloading without you clicking anything). The KeyAuth download function provides the bytes, and then you get to decide what to do with those. This example shows how to write it to a file named text.txt in the same folder as the program, though you could execute with RunPE or whatever you want.
385624 is the file ID you get from the dashboard after adding file.
byte[] result = KeyAuthApp.download("385624");
if (!KeyAuthApp.response.success)
{
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
Thread.Sleep(2500);
Environment.Exit(0);
}
else
File.WriteAllBytes(Directory.GetCurrentDirectory() + "\\test.txt", result);Allow users to communicate amongst themselves in your program.
Example from the form example on how to fetch the chat messages.
var messages = Login.KeyAuthApp.chatget("chatChannelNameHere");
if (messages == null)
{
dataGridView1.Rows.Insert(0, "KeyAuth", "No Chat Messages", UnixTimeToDateTime(DateTimeOffset.Now.ToUnixTimeSeconds()));
}
else
{
foreach (var message in messages)
{
dataGridView1.Rows.Insert(0, message.author, message.message, UnixTimeToDateTime(long.Parse(message.timestamp)));
}
}Example from the form example on how to send chat message.
if (Login.KeyAuthApp.chatsend(chatmsg.Text, chatchannel))
{
dataGridView1.Rows.Insert(0, Login.KeyAuthApp.user_data.username, chatmsg.Text, UnixTimeToDateTime(DateTimeOffset.Now.ToUnixTimeSeconds()));
}
else
chatmsg.Text = "Status: " + Login.KeyAuthApp.response.message;Looking for a Discord bot made by the KeyAuth & RestoreCord founder that you can use to backup your Discord members, server settings, and messages? Go to https://vaultcord.com
