MT5 Device Fingerprint Tool

A lightweight and reliable HWID-based device fingerprint generator for MetaTrader 5, designed to help developers protect paid indicators, EAs, and scripts.
This tool collects stable terminal and account identifiers, combines them into a normalized machine signature, and produces a SHA-256 license code without using any external DLLs.

Ideal for sellers who need per-user licensing, hardware locking, and simple offline verification inside their MQL5 products.

Features

• Generates a unique device fingerprint from stable MT5 properties
• Produces a SHA-256 hash for licensing (no external dependencies)
• Works fully inside MetaTrader 5 (pure MQL5 implementation)
• Zero DLL imports, fully compatible with MetaTrader Market rules
• Easy integration with commercial indicators and EAs
• Clean, readable, well-structured code
• Includes raw machine ID + final hashed license code
• Suitable for offline licensing workflows

---

Use Case

This tool is commonly used for:

• Selling MT5 indicators that must run only on specific accounts or machines
• Verifying customers before delivering the main product
• Reinforcing anti-piracy measures in commercial EAs
• Binding licenses to client hardware or trading account
• Allowing manual approval of each client via hashed code

---

How It Works

1. The user installs the fingerprint indicator.
2. The indicator collects a set of non-changing identifiers:
   • Account login
   • Broker server
   • Terminal company
   • Terminal paths
   • Common data path
3. The concatenated string is hashed using MT5's built-in CryptEncode with CRYPT_HASH_SHA256.
4. The user sends the hash to the seller.
5. The seller embeds this hash inside the final product (indicator/EA).
6. The main indicator checks the customer’s hardware hash at runtime and stops execution if not authorized.

---

Example Output

When the indicator runs, it displays something like:

Your License Code: 3A9F1E3C77D50D0E25F0A53BD4E21D7DF917B8F9EC57E3E82890F2C542A19F5C

This code can then be stored inside your licensed product.

Installation

1. Clone the repository:

git clone https://github.com/BaseMax/mt5-device-fingerprint-tool

2. Copy mt5-device-fingerprint-tool.mq5 (or the provided file) into:

MQL5/Indicators/

3. Compile the file in MetaEditor.
4. Attach the indicator to any chart inside MetaTrader 5.

Code Overview

The core functions include:

• GetMachineID()
  Collects stable system/account identifiers.

• SHA256_hex_from_string()
  Generates a SHA-256 hex hash using MT5's built-in cryptography.

• CharArrayToHex()
  Utility to convert raw bytes to an uppercase hex string.

The generated hash is cryptographically strong and machine-specific.

---

Licensing Your Own Indicator / EA

Inside your commercial product, implement a check similar to:

string AllowedHash = "PUT_CUSTOMER_HASH_HERE";

if (DeviceHash != AllowedHash)
{
    Alert("License error – unauthorized machine.");
    return INIT_FAILED;
}

You may also close the chart or stop execution depending on your protection strategy.

---

Roadmap

• Add optional obfuscation for machine ID
• Add SHA-1 and MD5 fallback options
• Add server-based online activation mode
• Provide a full licensing framework (client + server)
• Add ready-to-use LicensedIndicator.mq5 template
