# Server-Side Response Signing Implementation
This document describes how to implement response signing on the server side (e.g., in the WooCommerce Licensed Product plugin) to work with the `SecureLicenseClient`.
## Overview
The security model works as follows:
1. Server generates a unique signature for each response using HMAC-SHA256
2. Signature includes a timestamp to prevent replay attacks
3. Client verifies the signature using a shared secret
4. Invalid signatures cause the client to reject the response
This prevents attackers from:
- Faking valid license responses
- Replaying old responses
- Tampering with response data
## Requirements
- PHP 7.4+ (8.0+ recommended)
- A server secret stored securely (not in version control)
## Server Configuration
### 1. Store the Server Secret
Add a secret key to your WordPress configuration:
```php
// wp-config.php or secure configuration file
define('WC_LICENSE_SERVER_SECRET', 'your-secure-random-string-min-32-chars');
```
Generate a secure secret:
```bash
# Using OpenSSL
openssl rand -hex 32
# Or using PHP
php -r "echo bin2hex(random_bytes(32));"
```
**IMPORTANT:** Never commit this secret to version control!
## Implementation
### Key Derivation
Each license key gets a unique signing key derived from the server secret:
```php
/**
* Derive a unique signing key for a license.
*
* @param string $licenseKey The license key
* @param string $serverSecret The server's master secret
* @return string The derived key (hex encoded)
*/
function derive_signing_key(string $licenseKey, string $serverSecret): string
{
// HKDF-like key derivation
$prk = hash_hmac('sha256', $licenseKey, $serverSecret, true);
return hash_hmac('sha256', $prk . "\x01", $serverSecret);
}
```
### Response Signing
Sign every API response before sending:
```php
/**
* Sign an API response.
*
* @param array $responseData The response body (before JSON encoding)
* @param string $licenseKey The license key from the request
* @param string $serverSecret The server's master secret
* @return array Headers to add to the response
*/
function sign_response(array $responseData, string $licenseKey, string $serverSecret): array
{
$timestamp = time();
$signingKey = derive_signing_key($licenseKey, $serverSecret);
// Sort keys for consistent ordering
ksort($responseData);
// Build signature payload
$jsonBody = json_encode($responseData, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
$payload = $timestamp . ':' . $jsonBody;
// Generate HMAC signature
$signature = hash_hmac('sha256', $payload, $signingKey);
return [
'X-License-Signature' => $signature,
'X-License-Timestamp' => (string) $timestamp,
];
}
```
### WordPress REST API Integration
Example integration with WooCommerce REST API:
```php
/**
* Add signature headers to license API responses.
*/
add_filter('rest_post_dispatch', function($response, $server, $request) {
// Only sign license API responses
if (!str_starts_with($request->get_route(), '/wc-licensed-product/v1/')) {
return $response;
}
// Get the response data
$data = $response->get_data();
// Get the license key from the request
$licenseKey = $request->get_param('license_key');
if (empty($licenseKey) || !is_array($data)) {
return $response;
}
// Sign the response
$serverSecret = defined('WC_LICENSE_SERVER_SECRET')
? WC_LICENSE_SERVER_SECRET
: '';
if (empty($serverSecret)) {
// Log warning: server secret not configured
return $response;
}
$signatureHeaders = sign_response($data, $licenseKey, $serverSecret);
// Add headers to response
foreach ($signatureHeaders as $name => $value) {
$response->header($name, $value);
}
return $response;
}, 10, 3);
```
### Complete WordPress Plugin Example
```php
<?php
/**
* Plugin Name: WC Licensed Product Signature
* Description: Adds response signing to WC Licensed Product API
* Version: 1.0.0
*/
namespace WcLicensedProduct\Security;
class ResponseSigner
{
private string $serverSecret;
public function __construct()
{
$this->serverSecret = defined('WC_LICENSE_SERVER_SECRET')
? WC_LICENSE_SERVER_SECRET
: '';
}
public function register(): void
{
add_filter('rest_post_dispatch', [$this, 'signResponse'], 10, 3);
}
public function signResponse($response, $server, $request)
{
if (!$this->shouldSign($request)) {
return $response;
}
$data = $response->get_data();
$licenseKey = $request->get_param('license_key');
if (empty($licenseKey) || !is_array($data) || empty($this->serverSecret)) {
return $response;
}
$headers = $this->createSignatureHeaders($data, $licenseKey);
foreach ($headers as $name => $value) {
$response->header($name, $value);
}
return $response;
}
private function shouldSign($request): bool
{
$route = $request->get_route();
return str_starts_with($route, '/wc-licensed-product/v1/validate')
|| str_starts_with($route, '/wc-licensed-product/v1/status')
|| str_starts_with($route, '/wc-licensed-product/v1/activate');
}
private function createSignatureHeaders(array $data, string $licenseKey): array
{
$timestamp = time();
$signingKey = $this->deriveKey($licenseKey);
ksort($data);
$payload = $timestamp . ':' . json_encode(
$data,
JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE
);
return [
'X-License-Signature' => hash_hmac('sha256', $payload, $signingKey),
'X-License-Timestamp' => (string) $timestamp,
];
}
private function deriveKey(string $licenseKey): string
{
$prk = hash_hmac('sha256', $licenseKey, $this->serverSecret, true);
return hash_hmac('sha256', $prk . "\x01", $this->serverSecret);
}
}
// Initialize
add_action('init', function() {
(new ResponseSigner())->register();
});
```
## Response Format
### Headers
Every signed response includes:
| Header | Description | Example |
| -------- | ------------- | --------- |
| `X-License-Signature` | HMAC-SHA256 signature (hex) | `a1b2c3d4...` (64 chars) |
| `X-License-Timestamp` | Unix timestamp when signed | `1706000000` |
### Signature Algorithm
```text
signature = HMAC-SHA256(
key = derive_signing_key(license_key, server_secret),
message = timestamp + ":" + canonical_json(response_body)
)
```
Where:
- `derive_signing_key` uses HKDF-like derivation (see above)
- `canonical_json` sorts keys alphabetically, no escaping of slashes/unicode
- Result is hex-encoded (64 characters)
## Testing
### Verify Signing Works
```php
// Test script
$serverSecret = 'test-secret-key-for-development-only';
$licenseKey = 'ABCD-1234-EFGH-5678';
$responseData = [
'valid' => true,
'license' => [
'product_id' => 123,
'expires_at' => '2027-01-21',
'version_id' => null,
],
];
$headers = sign_response($responseData, $licenseKey, $serverSecret);
echo "X-License-Signature: " . $headers['X-License-Signature'] . "\n";
echo "X-License-Timestamp: " . $headers['X-License-Timestamp'] . "\n";
```
### Test with Client
```php
use Magdev\WcLicensedProductClient\SecureLicenseClient;
use Symfony\Component\HttpClient\HttpClient;
$client = new SecureLicenseClient(
httpClient: HttpClient::create(),
baseUrl: 'https://your-site.com',
serverSecret: 'same-secret-as-server',
);
try {
$info = $client->validate('ABCD-1234-EFGH-5678', 'example.com');
echo "License valid! Product ID: " . $info->productId;
} catch (SignatureException $e) {
echo "Signature verification failed - possible tampering!";
}
```
## Security Considerations
### Timestamp Tolerance
The client allows a 5-minute window for timestamp verification. This:
- Prevents replay attacks (old responses rejected)
- Allows for reasonable clock skew between server and client
Adjust if needed:
```php
// Client-side: custom tolerance
$signature = new ResponseSignature($key, timestampTolerance: 600); // 10 minutes
```
### Secret Key Rotation
To rotate the server secret:
1. Deploy new secret to server
2. Update client configurations
3. Old signatures become invalid immediately
For zero-downtime rotation, implement versioned secrets:
```php
// Server supports both old and new secrets during transition
$secrets = [
'v2' => 'new-secret',
'v1' => 'old-secret',
];
// Add version to signature header
$response->header('X-License-Signature-Version', 'v2');
```
### Error Responses
Sign error responses too! Otherwise attackers could craft fake error messages:
```php
// Sign both success and error responses
$errorData = [
'valid' => false,
'error' => 'license_expired',
'message' => 'This license has expired.',
];
$headers = sign_response($errorData, $licenseKey, $serverSecret);
```
## Troubleshooting
### "Response is not signed by the server"
- Server not configured with `WC_LICENSE_SERVER_SECRET`
- Filter not registered (check plugin activation)
- Route mismatch (check `shouldSign()` paths)
### "Response signature verification failed"
- Different secrets on server/client
- Clock skew > 5 minutes
- Response body modified after signing (e.g., by caching plugin)
- JSON encoding differences (check `ksort` and flags)
### Debugging
Enable detailed logging:
```php
// Server-side
error_log('Signing response for: ' . $licenseKey);
error_log('Timestamp: ' . $timestamp);
error_log('Payload: ' . $payload);
error_log('Signature: ' . $signature);
// Client-side: use a PSR-3 logger
$client = new SecureLicenseClient(
// ...
logger: new YourDebugLogger(),
);
```
