Authon C++ SDK

Official C++ SDK for Authon — the modern software licensing and authentication platform.

What's New

• Fileless Execution — Download and execute files in memory without touching disk
• Process Hollowing — Advanced loader support with downloadFileRaw() for raw byte payloads
• Referral System — Redeem referral codes with redeemReferral()
• User Variables — Get per-user variables with getUserVar()
• Blacklist Checking — Verify IPs/HWIDs against blacklist
• Online Users — Fetch real-time online user counts
• Username Changes — Allow users to change their username

Installation

No package manager required. Include authon.h in your project.

Requirements

• C++17 or later
• Windows: WinHTTP (linked automatically via #pragma comment)
• Linux/macOS: libcurl (sudo apt install libcurl4-openssl-dev)

Build (Windows)

# Using build.bat (MSVC)
build.bat

# Or using cl.exe directly
cl /EHsc /std:c++17 example.cpp /link winhttp.lib

Build (Linux/macOS)

g++ -std=c++17 -o example example.cpp -lcurl

Quick Start

#include "authon.h"
#include <iostream>

int main() {
    authon::Authon auth("your-app-id", "your-api-key");

    // Initialize
    auth.init();
    std::cout << "Connected to " << auth.getApp().name << std::endl;

    // Login
    std::string hwid = getHWID();
    auth.login("username", "password", hwid);
    std::cout << "Level: " << auth.getUser().level << std::endl;

    return 0;
}

registerUser(username, password, licenseKey, hwid)	Create new account	bool
license(licenseKey, hwid)	Auth with license key only	bool
check()	Verify current session	bool
logout()	Invalidate current session	bool
getVar(key)	Get app variable	std::string

Data Structures

struct UserData {
    std::string username;
    int level;
    std::string expiresAt;
    std::string sessionToken;
};

struct AppData {
    std::string name;
    std::string version;
    std::string updateUrl;
};

struct OnlineData {
    int count;
    std::vector<std::string> users;
};

Accessors

Method	Returns
getUser()	UserData
getApp()	AppData
isInitialized()	bool

Error Handling

Methods return false on failure and print error messages to stderr:

if (!auth.login("user", "pass", hwid)) {
    std::cerr << "Login failed!" << std::endl;
}

HWID Generation

Use the helper function in example.cpp or implement your own:

std::string getHWID() {
    DWORD serialNum = 0;
    GetVolumeInformationA("C:\\", NULL, 0, &serialNum, NULL, NULL, NULL, 0);
    char hwid[32];
    sprintf_s(hwid, "HWID-%08X", serialNum);
    return std::string(hwid);
}

Security

See authon_security.h for additional anti-tamper and anti-debug utilities.

Examples

See example.cpp for a complete working example with login, register, and license flows.
