# Multi-Language Integration Templates

AuthVaultix provides official, production-ready SDKs and open-source example projects for popular programming languages. Each wrapper includes built-in HMAC-SHA256 response signature verification, anti-replay nonce handling, and automatic Hardware ID (HWID) generation.

---

> [!TIP]
> **Instant Testing Credentials:** You can immediately test any template using our public demo application credentials:
> - **App Name:** `DemoApp`
> - **Owner ID:** `owner_id`
> - **App Secret:** `app_secret`
> - **Version:** `1.0`

# 🚀 Quick Integration Workflow

Every AuthVaultix example follows a zero-trust cryptographic lifecycle to prevent client-side tampering and response spoofing:

```mermaid
sequenceDiagram
    autonumber
    participant App as Client Application
    participant SDK as AuthVaultix SDK
    participant API as AuthVaultix Cloud API

    App->>SDK: Initialize (App Name, Owner ID, Secret, GUID)
    SDK->>API: POST /api/1.0/ (init request + GUID)
    API-->>SDK: Signed JSON Response + Signature Header
    SDK->>SDK: Verify HMAC-SHA256 Signature (SignKey)
    alt Signature Valid
        SDK-->>App: Initialization Successful (Session ID)
        App->>SDK: Login / License Authenticate
        SDK->>API: POST /api/1.0/ (login + sessionid)
        API-->>SDK: Signed Response (User Data / Subscriptions)
        SDK->>SDK: Verify HMAC-SHA256 (SessionKey)
        SDK-->>App: Access Granted
    else Signature Invalid / MITM Detected
        SDK-->>App: Security Violation (Terminate Execution)
    end
```

# 🛡️ Developer Production Checklist

Before releasing to end users, complete these security hardening steps:

> [!IMPORTANT]
> **Client Binary Obfuscation:** AuthVaultix protects network payloads and server authentication logic. Protecting local memory and binary code is your responsibility using binary protectors:
> - **C / C++:** Protect compiled binaries with [VMProtect](https://vmpsoft.com) or [Themida](https://www.oreans.com).
> - **C# (.NET):** Obfuscate assemblies using **ConfuserEx**, **.NET Reactor**, or **Eazfuscator.NET**.
> - **Python:** Compile scripts to C extensions via **Nuitka** or encrypt bytecode with **PyArmor**.
> - **Node.js / Electron:** Protect renderer/main bundles with **Bytenode** or **JavaScript Obfuscator**.

1. **Enable SSL Certificate Pinning:** Strictly restrict server connections to `authvaultix.com` SSL certificates to neutralize local MITM proxy tools (Fiddler, Charles Proxy, HTTP Toolkit).
2. **Scatter Authentication Calls:** Do not isolate authentication logic inside a single `if (login)` block at startup. Call `app.check_session()` periodically in background threads during execution.
3. **Store Secrets Remotely:** Never embed backend API keys, third-party database passwords, or sensitive URLs in the binary. Store them in AuthVaultix **Global Variables** or **User Variables** instead of hardcoding them in the binary.
