Features -------- [](#features) - ✅ Offline validation (no internet required) - ✅ RSA-4096 signature verification - ✅ Configurable caching - ✅ Optional grace period - ✅ Hardware binding support - ✅ Product key validation - ✅ Feature flags (JSON-based) - ✅ Laravel middleware included - ✅ Facade support Requirements ------------ [](#requirements) - PHP 8.1+ - Laravel 9.0+ - OpenSSL extension - JSON extension Installation ------------ [](#installation) ``` composer require nazrulalif/laravel-pem-license-validator:dev-master ``` ### Publish Configuration [](#publish-configuration) ``` php artisan vendor:publish --provider="Nazrulalif\LaravelPemLicenseValidator\LicenseServiceProvider" ``` This creates `config/license.php` ### Place License File [](#place-license-file) Place your `license.pem` file in: ``` storage/app/license.pem ``` Configuration ------------- [](#configuration) Edit `config/license.php`: ``` return [ 'license_path' => storage_path('app/license.pem'), 'cache' => [ 'enabled' => true, 'ttl' => 86400, // 24 hours 'driver' => 'file', ], 'grace_period_days' => 0, // 0=disabled, 7=7 days after expiry 'product_key' => env('LICENSE_PRODUCT_KEY'), // Optional product validation 'public_key' => env('LICENSE_PUBLIC_KEY', '-----BEGIN PUBLIC KEY-----...'), 'on_failure' => [ 'redirect' => '/license-expired', 'log' => true, ], ]; ``` ### Environment Variables [](#environment-variables) Add these to your `.env` file: ``` LICENSE_PATH=storage/app/license.pem LICENSE_CACHE_ENABLED=true LICENSE_CACHE_TTL=86400 LICENSE_GRACE_PERIOD_DAYS=0 LICENSE_PRODUCT_KEY=your-product-key LICENSE_PUBLIC_KEY="-----BEGIN PUBLIC KEY----- ...your public key here... -----END PUBLIC KEY-----" LICENSE_FAILURE_REDIRECT=/license-expired LICENSE_FAILURE_LOG=true LICENSE_FAILURE_ABORT_CODE=403 ``` **Note:** `LICENSE_PRODUCT_KEY` is optional. If set, the license must contain a matching `productKey` field for validation to pass. Usage ----- [](#usage) ### Basic Validation [](#basic-validation) ``` use Nazrulalif\LaravelPemLicenseValidator\LicenseValidator; $validator = new LicenseValidator(config('license')); if ($validator->isValid()) { $license = $validator->getLicenseData(); echo "Valid until: " . $license['expiryDate']; } else { abort(403, 'Invalid license'); } ``` ### Using Facade [](#using-facade) ``` use Nazrulalif\LaravelPemLicenseValidator\Facades\License; if (License::isValid()) { $daysLeft = License::getDaysRemaining(); echo "License expires in {$daysLeft} days"; } ``` ### Middleware Protection [](#middleware-protection) Register in `app/Http/Kernel.php`: ``` protected $middlewareAliases = [ 'license' => \Nazrulalif\LaravelPemLicenseValidator\Middleware\ValidateLicense::class, ]; ``` Use in routes: ``` Route::middleware('license')->group(function () { Route::get('/dashboard', [DashboardController::class, 'index']); Route::get('/settings', [SettingsController::class, 'index']); }); ``` ### Bootstrap Validation [](#bootstrap-validation) In `app/Providers/AppServiceProvider.php`: ``` public function boot() { try { $validator = app(\Nazrulalif\LaravelPemLicenseValidator\LicenseValidator::class); if (!$validator->isValid()) { abort(403, 'Invalid or expired license: ' . $validator->getError()); } // Check grace period if ($validator->isInGracePeriod()) { logger()->warning('License in grace period. Days remaining: ' . $validator->getDaysRemaining()); } } catch (\Exception $e) { abort(500, 'License validation error: ' . $e->getMessage()); } } ``` ### Feature Checks [](#feature-checks) ``` use Nazrulalif\LaravelPemLicenseValidator\Facades\License; // Check if feature exists if (License::hasFeature('api_access')) { // Enable API routes } // Get feature value with default $maxUsers = License::getFeature('UserLimit', 10); // Get all features $features = License::getLicenseData()['features']; ``` API Reference ------------- [](#api-reference) ### LicenseValidator [](#licensevalidator) ``` // Validate license $validator->validate(): array // Check if valid $validator->isValid(): bool // Get license data $validator->getLicenseData(): array // Get days remaining $validator->getDaysRemaining(): int // Check grace period $validator->isInGracePeriod(): bool // Get feature value $validator->getFeature(string $key, mixed $default = null): mixed // Check feature exists $validator->hasFeature(string $key): bool // Get error message $validator->getError(): ?string ``` License Data Structure ---------------------- [](#license-data-structure) ``` { "productKey": "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX", "licenseId": "LIC-1234567890", "licenseType": "PROFESSIONAL", "companyName": "Acme Corporation", "email": "customer@example.com", "maxDevices": 5, "features": { "UserLimit": 50, "sso": true, "api_access": true, "storage_gb": 100 }, "hardwareId": null, "issueDate": "2025-01-01T00:00:00Z", "expiryDate": "2026-01-01T00:00:00Z" } ``` Exception Handling ------------------ [](#exception-handling) ``` use Nazrulalif\LaravelPemLicenseValidator\Exceptions\LicenseException; try { $validator->validate(); } catch (LicenseException $e) { switch ($e->getCode()) { case LicenseException::FILE_NOT_FOUND: // Handle missing file break; case LicenseException::INVALID_SIGNATURE: // Handle tampered license break; case LicenseException::EXPIRED: // Handle expiry break; case LicenseException::HARDWARE_MISMATCH: // Handle hardware binding break; case LicenseException::PRODUCT_KEY_MISMATCH: // Handle product key validation failure break; } } ``` Troubleshooting --------------- [](#troubleshooting) ### License file not found [](#license-file-not-found) Ensure `license.pem` exists at the configured path (default: `storage/app/license.pem`) ### Invalid signature [](#invalid-signature) - License file may be corrupted or tampered - Public key in config doesn't match the key used to sign the license ### Product key mismatch [](#product-key-mismatch) - The `productKey` in the license doesn't match `LICENSE_PRODUCT_KEY` in your `.env` - License was issued for a different product - Remove `LICENSE_PRODUCT_KEY` from `.env` to disable product key validation ### Permission denied [](#permission-denied) ``` chmod 644 storage/app/license.pem ``` ### Cache issues [](#cache-issues) Clear license cache: ``` License::clearCache(); ``` Security -------- [](#security) - Never commit `license.pem` to version control - Add to `.gitignore`: `storage/app/license.pem` - Keep public key secure in `.env` file - Use HTTPS when transferring license files Support ------- [](#support) For issues or questions, contact: License ------- [](#license) MIT License - see LICENSE file ### Health Score 29 — LowBetter than 57% of packages Maintenance60 Regular maintenance activity Popularity1 Limited adoption so far Community6 Small or concentrated contributor base Maturity44 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
