This package can create URLs with a limited lifetime. This is done by adding an expiration date and a signature to the URL.

This is how you can create signed URL that's valid for 30 days:

UrlSigner::sign('', 30);

The output will look like this:

The URL can be validated with the validate-function.


The package also provides a middleware to protect routes.


You're free to use this package (it's MIT-licensed), but if it makes it to your production environment we highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using.

As you would have guessed the package can be installed via Composer:

composer require spatie/laravel-url-signer

To enable the package, register the serviceprovider, and optionally register the facade:

// config/app.php

'providers' => [

'aliases' => [
    'UrlSigner' => Spatie\UrlSigner\Laravel\UrlSignerFacade::class,


The configuration file can optionally be published via:

php artisan vendor:publish --provider="Spatie\UrlSigner\Laravel\UrlSignerServiceProvider"

This is the contents of the file:

return [

    * This string is used the to generate a signature. You should
    * keep this value secret.
    'signatureKey' => config('app.key'),

     * The default expiration time of a URL in days.
    'default_expiration_time_in_days' => 1,

     * These strings are used a parameter names in a signed url.
    'parameters' => [
        'expires' => 'expires',
        'signature' => 'signature',



Signing URLs

URL's can be signed with the sign-method:


By default the lifetime of an URL is one day. This value can be change in the config-file. If you want a custom life time, you can specify the number of days the URL should be valid:

//the generated URL will be valid for 5 days.
UrlSigner::sign('', 5);

For fine grained control, you may also pass a DateTime instance as the second parameter. The url will be valid up to that moment. This example uses Carbon for convenience:

//This URL will be valid up until 2 hours from the moment it was generated.
UrlSigner::sign('', Carbon\Carbon::now()->addHours(2) );

Validating URLs

To validate a signed URL, simply call the validate()-method. This return a boolean.


Protecting routes with middleware

The package also provides a middleware to protect routes:

Route::get('protected-route', ['middleware' => 'signedurl', function () {
    return 'Hello secret world!';

Your app will abort with a 403 status code if the route is called without a valid signature.
