Laravel Encrypted Route Params

🔒 Stop ID Scraping & Leakage with Transparent URL Encryption

Are you still exposing raw database IDs in your URLs?

https://your-app.com/invoices/1024

The Problem

Exposing raw IDs is a major security and business intelligence risk:

1. ID Scraping: Competitors can easily guess next/previous IDs to scrape your data.
2. Business Intelligence Leakage: Anyone can see exactly how many orders, users, or invoices you have just by looking at the URL.
3. Insecure Direct Object Reference (IDOR): While middleware should prevent unauthorized access, raw IDs make it tempting for attackers to probe for weaknesses.
4. Ugly URLs: Raw IDs feel "naked" and less professional than modern, obfuscated identifiers.

The Solution

Laravel Encrypted Route Params provides a seamless, "drop-in" way to encrypt sensitive path parameters using Laravel’s native Crypt facade.

It handles everything automatically:

• Transparent Encryption: Use route() as normal; it encrypts the parameters on the fly.
• Automatic Decryption: Middleware decrypts values before implicit route model binding, so your controllers don't even know it happened.
• Shorter Tokens: Optional compact mode for cleaner, shorter URLs.
• JSON Support: Can also decrypt tokens inside JSON request payloads.

• Model-Level Control: Use a Trait to automatically encrypt IDs in all URLs and JSON resources.

• PHP ^8.1
• Laravel ^10.0|^11.0|^12.0|^13.0
• A valid APP_KEY

🚀 Installation

The package is auto-discovered. If discovery is disabled, register the provider manually:

⚙️ Quick Start

1. Middleware Setup (Required)

Decryption must run before SubstituteBindings.

Laravel 11 / 12 / 13 (bootstrap/app.php)

2. Usage on Routes

Just add ->encrypted() to any route definition:

3. Generate URLs

Just use the standard route() helper! If transparent_url_generation is enabled (default), it just works:

🏛️ Model-Level Control (Automatic)

Instead of marking every route, you can enable encryption directly on your Eloquent models. This is useful for sensitive IDs that should always be encrypted in URLs and JSON responses.

1. Add the Trait

Add HasEncryptedAttributes to your model and define which attributes should be encrypted:

2. What this does:

• Automatic URLs: route('invoices.show', $invoice) will now automatically produce an encrypted URL, even if the route is NOT marked with ->encrypted().
• Automatic JSON: When you return the model from a controller, use it in a JsonResource, or call $invoice->toArray(), the listed attributes will be encrypted automatically.
• Transparent Decryption: The middleware automatically detects models using this trait and decrypts the route parameters before they reach your controller.

🛠️ Advanced Features

Selecting Specific Parameters

Shorter Tokens (cipher = compact)

Tired of long Base64 strings? Switch to compact mode in your .env:

This uses AES-256-GCM + HKDF to produce significantly shorter tokens while maintaining high security.

JSON API Support

Decrypt parameters sent inside JSON POST bodies automatically by adding the middleware. You can use the provided alias encrypted.json.request (once configured in config):

🧪 Helper Methods

The package provides several global helper methods for manual encryption/decryption:

encrypt_route_param(mixed $value)

Encrypt a scalar value using the package's configuration. Useful for manually building JSON responses or payloads.

decrypt_route_param(string $token)

Decrypt a token produced by the package.

encrypted_route(string $name, array $parameters = [], bool $absolute = true)

Explicitly generate an encrypted route URL. This is useful if you have transparent_url_generation set to false.
