# Create signed URLs with a limited lifetime in Laravel
[](https://packagist.org/packages/spatie/laravel-url-signer)
[](https://travis-ci.org/spatie/laravel-url-signer)

This package can create URLs with a limited lifetime. This is done by adding an expiration date and a signature to the URL.
The difference with [Laravel's native route signing](https://laravel.com/docs/master/urls#signed-urls) is that using this package:
- you can easily use signed URLs between different apps
- the signing secret used is not tied to the app key
- you can easily sign any URL (and not only a route belonging to your app)
This is how you can create signed URL that's valid for 30 days:
```php
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
UrlSigner::sign('https://myapp.com/protected-route', now()->addDays(30));
```
The output will look like this:
```
https://app.com/protected-route?expires=xxxxxx&signature=xxxxxx
```
The URL can be validated with the `validate`-function.
```php
// returns `true` if the signed URL is valid, `false` if not
UrlSigner::validate('https://app.com/protected-route?expires=xxxxxx&signature=xxxxxx');
```
The package also provides [a middleware to protect routes](https://github.com/spatie/laravel-url-signer#protecting-routes-with-middleware).
## Support us
[
](https://spatie.be/github-ad-click/laravel-url-signer)
We invest a lot of resources into creating [best in class open source packages](https://spatie.be/open-source). You can support us by [buying one of our paid products](https://spatie.be/open-source/support-us).
We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on [our contact page](https://spatie.be/about-us). We publish all received postcards on [our virtual postcard wall](https://spatie.be/open-source/postcards).
## Installation
As you would have guessed the package can be installed via composer:
```bash
composer require spatie/laravel-url-signer
```
You must set an environment variable called `URL_SIGNER_SIGNATURE_KEY` and set it to a long secret value. This value will be used to sign and validate signed URLs.
```
php artisan generate:url-signer-signature-key
{--s|show : Display the key instead of modifying files.}
{--always-no : Skip generating key if it already exists.}
{--f|force : Skip confirmation when overwriting an existing key.}
```
The configuration file can optionally be published via:
```bash
php artisan vendor:publish --tag="url-signer-config"
```
This is the content of the file:
```php
return [
/*
* This string is used the to generate a signature. You should
* keep this value secret.
*/
'signature_key' => env('URL_SIGNER_SIGNATURE_KEY'),
/*
* The default expiration time of a URL in seconds.
*/
'default_expiration_time_in_seconds' => 60 * 60 * 24,
/*
* These strings are used a parameter names in a signed url.
*/
'parameters' => [
'expires' => 'expires',
'signature' => 'signature',
],
];
```
## Usage
URL's can be signed with the `sign`-method:
```php
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
UrlSigner::sign('https://myapp.com/protected-route');
```
By default, the lifetime of an URL is one day. This value can be change in the config file.
If you want a custom lifetime, you can specify the number of days the URL should be valid:
```php
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
// the generated URL will be valid for 5 minutes.
UrlSigner::sign('https://myapp.com/protected-route', now()->addMinutes(5));
// alternatively you could also pass the amount of seconds
UrlSigner::sign('https://myapp.com/protected-route', 60 * 5);
```
### Validating URLs
To validate a signed URL, simply call the `validate()`-method. This method returns a boolean.
```php
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
UrlSigner::validate('https://app.com/protected-route?expires=xxxxxx&signature=xxxxxx');
```
### Protecting routes with middleware
The package provides a middleware to protect routes.
To use it you must first register the `Spatie\UrlSigner\Laravel\Middleware\ValidateSignature` as route middleware in your HTTP kernel.
```php
// in app/Http/Kernel.php
protected $routeMiddleware = [
// ...
'signed-url' => \Spatie\UrlSigner\Laravel\Middleware\ValidateSignature::class,
];
```
Next, you can apply it on any route you want.
```php
Route::get('protected-route', fn () => 'Hello secret world!')
->middleware('signed-url');
```
Your app will abort with a 403 status code if the route is called without a valid signature.
