README

A lightweight and developer-friendly Laravel package for verifying domain ownership using DNS TXT records.

🚀 Features

• 🔐 Verifies domain ownership via DNS TXT records.
• ⚙️ Easily configurable and customizable.
• 🔗 Prefix-based hashing for safe and unique TXT records.
• ⚡ Simple to integrate into any Laravel project.

📦 Installation

composer require sysborg/check-my-domain

🛠️ Configuration

Optionally publish the configuration file:

php artisan vendor:publish --tag=check-my-domain-config

This will publish the file to: config/checkMyDomain.php

Example config (config/checkMyDomain.php)

return [

    'prefix' => 'sbv',

    'settings' => [
        'use-domain' => true,
    ],
];

🧠 Usage

Injecting the Service

use Facades\Sysborg\CheckMyDomain\Lib\Domain;

$domainService = Domain::methodName(...parameters);

Generating a TXT Record

$record = Domain::generateTxtRecord('example.com', 'user-123');

// Output: sbv=4f8a3bd9eabf3c22bb9a5e2dd5c03f4c8ae6d2ef9f709137b20a2fd4e9d1

Validating Against DNS

$isVerified = Domain::compareTxtRecord('example.com', $record);

if ($isVerified) {
    echo '✅ Domain verified successfully!';
} else {
    echo '❌ Domain verification failed.';
}

🧪 Testing

composer test

Or use PHPUnit directly if configured:

./vendor/bin/phpunit

📚 How It Works

1. The package generates a unique hash based on your prefix, user ID, domain, and timestamp.
2. The user adds the TXT record to their DNS zone (e.g. sbv=abcdef123456...).
3. You use compareTxtRecord() to query the domain and validate if the correct TXT record is present.

This makes it easy to verify domain ownership for:

• User-generated domains
• SaaS onboarding
• API clients or webhook callbacks

🧩 Integration Ideas

• 🔗 Connect to onboarding flows (verify user domains).
• 🛡️ Add protection to webhook registration or integrations.
• ⚙️ Automate DNS verification with APIs like Cloudflare.
