📦 Installation

Step 1: Install via Composer

composer require securecrypto/laravel-encryption

✅ Keys are automatically generated and added to your .env file!

Step 2: Publish Configuration

php artisan vendor:publish --tag=secure-crypto-config

This creates config/crypt.php in your application.

Step 3: Check Auto-Generated Keys

After installation, check your .env file. You'll see:

# Response Crypt Package - Auto-generated Keys
RESPONSE_CRYPT_KEY="oJh92F4FPq7xE3+mvVuEXA=="
RESPONSE_CRYPT_IV="mWnVJb8mZ3hXjx9P9F2pG6F8ZT6Pb9vh+bDqWzTVkMg="

These are automatically created on package installation! You can customize them if needed.

Step 4: Generate New Keys (Optional)

If you want to regenerate keys:

# Generate and save to .env
php artisan crypt:keys

# Show keys without saving
php artisan crypt:keys --show

# Force in production
php artisan crypt:keys --force

Beautiful Console Output:

$ php artisan crypt:keys

   INFO  Encryption keys generated successfully!

  ✓ RESPONSE_CRYPT_KEY ........................... oJh92F4FPq7xE3+mv...
  ✓ RESPONSE_CRYPT_IV ............................ mWnVJb8mZ3hXjx9P9...

  ✓ Keys added to .env file

⚙️ Configuration

Environment Variables

# Enable/Disable encryption
RESPONSE_CRYPT_ENABLED=true

# Encryption driver
# Options: hex, openssl_fixed, openssl, laravel
RESPONSE_CRYPT_DRIVER=hex

# Auto-generated keys (or set custom ones)
RESPONSE_CRYPT_KEY="your-key-here"
RESPONSE_CRYPT_IV="your-iv-here"

# Optional: Enable logging
RESPONSE_CRYPT_LOG_ENABLED=false

Encryption Drivers (Strategy Pattern)

The package uses Strategy Design Pattern for flexible encryption:

Driver	Encoding	IV	Implementation	Best For
`hex`	Hexadecimal	Fixed	`HexEncryptionDriver`	Mobile Apps 📱
`openssl_fixed`	Base64	Fixed	`OpenSSLDriver`	Web apps with fixed IV
`openssl`	Base64	Random	`OpenSSLDriver`	Max Security 🔒
`laravel`	Base64	Random	`LaravelEncryptionDriver`	Simple projects

Default: hex - Perfect for mobile compatibility!

Want custom encryption? Just implement EncryptionDriverInterface!

Config File Options

The config/crypt.php file offers extensive customization:

return [
    // Enable/disable encryption globally
    'enabled' => env('RESPONSE_CRYPT_ENABLED', true),

    // Encryption driver: hex, openssl_fixed, openssl, laravel
    'driver' => env('RESPONSE_CRYPT_DRIVER', 'hex'),

    // Encryption key (auto-generated on install)
    'key' => env('RESPONSE_CRYPT_KEY'),

    // Encryption IV (auto-generated on install)
    'iv' => env('RESPONSE_CRYPT_IV'),

    // Enable response encryption
    'encrypt_response' => true,

    // Enable request decryption
    'decrypt_request' => true,

    // Response wrapper key
    'response_wrapper_key' => 'payload',

    // Request payload key
    'request_payload_key' => 'payload',

    // Include metadata in response
    'include_meta' => true,

    // Routes to exclude from encryption
    'excluded_routes' => [
        'login',
        'register',
        'sanctum/csrf-cookie',
        'health',
    ],

    // Response keys to exclude from encryption
    'excluded_keys' => [
        'token_type',
        'expires_in',
    ],

    // Cipher algorithm
    'cipher' => 'AES-256-CBC',
];

💻 Usage

Basic Route Middleware

Simple Enable/Disable Pattern (Recommended):

use Illuminate\Support\Facades\Route;

// Enable/disable encryption with environment variable
$middlewares = env('RESPONSE_CRYPT_ENABLED', false) 
    ? ['request.decrypt', 'response.encrypt'] 
    : [];

Route::middleware($middlewares)->group(function () {
    // All your API routes here
    Route::post('/login', [AuthController::class, 'login']);
    Route::get('/users', [UserController::class, 'index']);
    Route::post('/posts', [PostController::class, 'store']);
});

Middleware Options

Middleware	Alias	Description
`EncryptApiResponse`	`response.encrypt`	Encrypts outgoing responses only
`DecryptApiRequest`	`request.decrypt`	Decrypts incoming requests only
`EncryptDecryptApi`	`api.crypt`	Both encrypt response and decrypt request

Example Usage:

// Only encrypt responses
Route::middleware(['response.encrypt'])->get('/api/data', function () {
    return response()->json(['message' => 'This will be encrypted']);
});

// Only decrypt requests
Route::middleware(['request.decrypt'])->post('/api/process', function () {
    return response()->json(['received' => request()->all()]);
});

// Both encrypt and decrypt
Route::middleware(['api.crypt'])->post('/api/secure', function () {
    return response()->json([
        'status' => true,
        'data' => request()->all()
    ]);
});

Using Facade

use Sanjeev\ResponseCrypt\Facades\ResponseCrypt;

// Encrypt data
$encrypted = ResponseCrypt::encrypt(['secret' => 'data', 'key' => 'value']);

// Decrypt data
$decrypted = ResponseCrypt::decrypt($encrypted);

// Encrypt array for response
$response = ResponseCrypt::encryptArray(['status' => true, 'data' => $data]);

// Decrypt request array
$data = ResponseCrypt::decryptArray($request->all());

Helper Functions

// Encrypt data
$encrypted = encrypt_data(['name' => 'John', 'email' => 'john@example.com']);

// Decrypt data
$decrypted = decrypt_data($encrypted);

// Encrypt for response
$response = encrypt_response(['status' => true, 'message' => 'Success']);

// Decrypt request
$data = decrypt_request($request->all());

🔄 Migration from Existing Setup

If you have an existing encryption implementation like this:

// Old way
$middlewares = env('IS_ENCRYPTION', false) 
    ? ['decrypt.request', 'encrypt.response'] 
    : [];

Simply change to:

// New way with Response Crypt
$middlewares = env('RESPONSE_CRYPT_ENABLED', false) 
    ? ['request.decrypt', 'response.encrypt'] 
    : [];

And update .env:

# Old
IS_ENCRYPTION=true
ENCRYPTION_KEY="..."
ENCRYPTION_IV="..."

# New (keys auto-generated on install)
RESPONSE_CRYPT_ENABLED=true
RESPONSE_CRYPT_KEY="auto-generated"
RESPONSE_CRYPT_IV="auto-generated"
RESPONSE_CRYPT_DRIVER=hex

✅ That's it! Your mobile app will continue working without any changes!

📱 Mobile App Compatibility

Hex Encoding (Default)

The package uses hex encoding by default (driver=hex), which is:

✅ Compatible with most mobile apps
✅ Compatible with existing implementations
✅ No changes needed in your mobile app code

Request Format

Send encrypted request:

{
  "payload": "3a4b5c6d7e8f9a0b1c2d3e4f..."
}

The server will automatically decrypt it!

Response Format

Server encrypts response:

{
  "encrypted": true,
  "payload": "1a2b3c4d5e6f7a8b9c0d1e2f...",
  "meta": {
    "algorithm": "hex",
    "timestamp": "2024-06-18T10:30:00Z"
  }
}

Your mobile app decrypts the payload field.

🎯 Complete Example

File: routes/api.php

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\API\AuthController;
use App\Http\Controllers\API\UserController;
use App\Http\Controllers\API\PostController;

// Encryption middleware toggle
$encryptionMiddlewares = env('RESPONSE_CRYPT_ENABLED', false) 
    ? ['request.decrypt', 'response.encrypt'] 
    : [];

// Public routes (no encryption)
Route::post('/login', [AuthController::class, 'login']);
Route::post('/register', [AuthController::class, 'register']);
Route::get('/health', function () {
    return response()->json(['status' => 'ok']);
});

// Protected encrypted routes
Route::middleware($encryptionMiddlewares)->group(function () {
    
    // Auth required routes
    Route::middleware(['auth:sanctum'])->group(function () {
        Route::get('/profile', [UserController::class, 'profile']);
        Route::post('/update-profile', [UserController::class, 'update']);
        Route::post('/logout', [AuthController::class, 'logout']);
        
        // Posts
        Route::get('/posts', [PostController::class, 'index']);
        Route::post('/posts', [PostController::class, 'store']);
        Route::get('/posts/{id}', [PostController::class, 'show']);
    });
    
    // Public encrypted routes
    Route::get('/users', [UserController::class, 'index']);
    Route::get('/blogs', [BlogController::class, 'index']);
});

File: .env

# Response Crypt Configuration
RESPONSE_CRYPT_ENABLED=true
RESPONSE_CRYPT_DRIVER=hex

# Auto-generated keys (created on package install)
RESPONSE_CRYPT_KEY="oJh92F4FPq7xE3+mvVuEXA=="
RESPONSE_CRYPT_IV="mWnVJb8mZ3hXjx9P9F2pG6F8ZT6Pb9vh+bDqWzTVkMg="

🔧 Advanced Configuration

Exclude Specific Routes

// config/crypt.php
'excluded_routes' => [
    'login',
    'register',
    'health',
    'api/public/*',
],

Exclude Response Keys

'excluded_keys' => [
    'token_type',
    'expires_in',
    'scope',
],

Example Response:

{
  "token_type": "Bearer",
  "expires_in": 3600,
  "encrypted": true,
  "payload": "encrypted-data-here"
}

The token_type and expires_in remain unencrypted!

🧪 Testing

Run package tests:

composer test

Or using PHPUnit:

vendor/bin/phpunit

Run specific test:

vendor/bin/phpunit tests/Unit/ResponseCryptServiceTest.php

🔒 Security Best Practices

✅ Always use HTTPS in production
✅ Keep encryption keys secure (never commit .env)
✅ Rotate keys regularly
✅ Use hex driver for mobile apps (compatible)
✅ Use openssl driver for maximum security (new projects)
✅ Monitor failed decryptions
✅ Validate all input data
✅ Use rate limiting on encrypted endpoints

For detailed security guidelines, see SECURITY.md

🏗️ Architecture & Design

Strategy Pattern Implementation

The package uses the Strategy Pattern for encryption drivers:

// Core Service (EncryptionService.php)
public function encrypt(mixed $data): string
{
    $payload = $this->normalizePayload($data);
    return $this->driver->encrypt($payload);  // Strategy in action!
}

// Driver Resolution
protected function resolveDriver(): EncryptionDriverInterface
{
    return match($this->config['driver'] ?? 'hex') {
        'hex' => new HexEncryptionDriver($this->config),
        'openssl' => new OpenSSLDriver($this->config),
        'laravel' => new LaravelEncryptionDriver($this->config),
        default => new HexEncryptionDriver($this->config),
    };
}

Want to Add Custom Driver?

Easy! Just implement the interface:

use Sanjeev\ResponseCrypt\Contracts\EncryptionDriverInterface;
use Sanjeev\ResponseCrypt\Drivers\BaseEncryptionDriver;

class MyCustomDriver extends BaseEncryptionDriver
{
    public function encrypt(string $data): string
    {
        // Your custom encryption logic
        return $encryptedData;
    }
    
    public function decrypt(string $encryptedData): string
    {
        // Your custom decryption logic
        return $decryptedData;
    }
    
    public function getName(): string
    {
        return 'my-custom-driver';
    }
}

Then use it:

RESPONSE_CRYPT_DRIVER=my-custom-driver

Example 1: Encrypt Response Only

use Illuminate\Support\Facades\Route;

Route::middleware(['response.encrypt'])->get('/api/users', function () {
    return response()->json([
        'status' => true,
        'data' => [
            'id' => 1,
            'name' => 'John Doe',
            'email' => 'john@example.com',
        ],
    ]);
});

Response:

{
  "encrypted": true,
  "payload": "eyJpdiI6IjRGNnNMOE1XYnhOV...",
  "meta": {
    "algorithm": "laravel",
    "timestamp": "2026-06-18T10:30:00Z"
  }
}

Example 2: Decrypt Request Only

Route::middleware(['request.decrypt'])->post('/api/process', function () {
    $data = request()->all();
    
    return response()->json([
        'status' => true,
        'message' => 'Data received',
        'data' => $data,
    ]);
});

Request:

{
  "payload": "eyJpdiI6IjRGNnNMOE1XYnhOV..."
}

The encrypted payload will be automatically decrypted and available via request()->all().

Example 3: Both Encrypt & Decrypt

Route::middleware(['api.crypt'])->post('/api/secure-transaction', function () {
    $data = request()->all();
    
    return response()->json([
        'transaction_id' => uniqid(),
        'status' => 'completed',
        'amount' => $data['amount'],
    ]);
});

Example 4: Protected Route Group

Route::middleware(['api.crypt', 'auth:sanctum'])->prefix('secure')->group(function () {
    Route::post('/transactions', [TransactionController::class, 'store']);
    Route::get('/profile', [ProfileController::class, 'show']);
});

Using the Facade

use Sanjeev\ResponseCrypt\Facades\ResponseCrypt;

// Encrypt data
$encrypted = ResponseCrypt::encrypt([
    'card_number' => '1234567890123456',
    'cvv' => '123',
]);

// Decrypt data
$decrypted = ResponseCrypt::decrypt($encrypted);

Using Helper Functions

// Encrypt
$encrypted = encrypt_data(['user_id' => 123, 'action' => 'login']);

// Decrypt
$decrypted = decrypt_data($encrypted);

Advanced Usage

🎨 Customize Response Structure (v1.4.0+)

NEW! Configure your own response format in config/crypt.php:

'response_structure' => [
    'success' => true,
    'status' => 200,
    'message' => 'success',
    'data' => '{payload}',      // Encrypted data goes here
    'encrypted' => '{encrypted}', // Boolean flag
    'meta' => '{meta}',          // Encryption metadata (or null to disable)
],

Before (default):

{
  "encrypted": true,
  "payload": "a2e19e18e6f504111...",
  "meta": {"algorithm": "hex", "cipher": "AES-256-CBC"}
}

After (customized):

{
  "success": true,
  "status": 200,
  "message": "success",
  "data": "a2e19e18e6f504111...",
  "encrypted": true,
  "meta": {"algorithm": "hex"}
}

🎛️ Control Encryption via Request Headers (v1.4.0+)

NEW! Users can disable encryption dynamically:

Option 1: Using Header

curl -H "X-Disable-Encryption: true" http://api.example.com/users

Option 2: Using Query Parameter

curl http://api.example.com/users?encrypted=false

Option 3: Using Accept Header (when enabled in config)

curl -H "Accept: application/json" http://api.example.com/users

Enable in config:

'allow_plain_via_accept' => true,

Exclude Specific Response Keys

Some keys like token_type or expires_in can remain unencrypted. Configure this in config/crypt.php:

'excluded_keys' => [
    'token_type',
    'expires_in',
],

Example Response:

{
  "token_type": "Bearer",
  "expires_in": 3600,
  "encrypted": true,
  "payload": "eyJpdiI6IjRGNnNMOE..."
}

Exclude Routes from Encryption

Add route patterns to skip encryption:

'excluded_routes' => [
    'login',
    'register',
    'password/*',
    'health',
],

Custom Error Handling

When decryption fails, the package returns a configurable error response:

'error_response' => [
    'status' => false,
    'message' => 'Invalid encrypted payload.',
    'error' => 'DECRYPTION_FAILED',
],

You can customize this in the config file.

Client-Side Integration

JavaScript Example

// Encrypt data before sending
async function encryptData(data, key) {
    // Use your preferred encryption library (e.g., CryptoJS)
    const encrypted = CryptoJS.AES.encrypt(
        JSON.stringify(data), 
        key
    ).toString();
    
    return encrypted;
}

// Send encrypted request
const data = { username: 'john', password: 'secret' };
const encrypted = await encryptData(data, 'your-encryption-key');

fetch('/api/process', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ payload: encrypted })
});

// Decrypt response
async function decryptResponse(encryptedPayload, key) {
    const bytes = CryptoJS.AES.decrypt(encryptedPayload, key);
    return JSON.parse(bytes.toString(CryptoJS.enc.Utf8));
}

See examples/javascript-client.js for a complete implementation.

Postman Integration

Import the Postman collection to test encrypted endpoints.

Testing

Run the test suite:

composer test

Or with coverage:

./vendor/bin/phpunit --coverage-html coverage

Security Considerations

⚠️ Important Security Notes:

Never log decrypted data in production environments
Use strong encryption keys - Laravel's APP_KEY should be 32 characters
Use HTTPS - Encryption in transit complements, doesn't replace TLS/SSL
Rotate keys regularly - Implement key rotation strategy for sensitive applications
Validate decrypted data - Always validate and sanitize decrypted input
Disable in development - Set RESPONSE_CRYPT_ENABLED=false for easier debugging

API Reference

ResponseCrypt Facade

// Encrypt data
ResponseCrypt::encrypt(mixed $data): string

// Decrypt data
ResponseCrypt::decrypt(string $encryptedData): mixed

// Check if encryption is enabled
ResponseCrypt::isEnabled(): bool

Helper Functions

encrypt_data(mixed $data): string
decrypt_data(string $encryptedData): mixed

Troubleshooting

Decryption Failed Error

Cause: Key mismatch or corrupted payload
Solution: Ensure both client and server use the same encryption key

Middleware Not Working

Cause: Middleware not registered
Solution: Clear cache with php artisan config:clear and php artisan cache:clear

Performance Issues

Cause: Encrypting large responses
Solution: Use selective encryption with excluded_keys or encrypt only sensitive fields
