Create and validate signed URLs with a limited lifetime
License: MIT License
Languages: PHP
This package can create URLs with a limited lifetime. This is done by adding an expiration date and a signature to the URL.
$urlSigner = new Sha256UrlSigner('randomkey');
$urlSigner->sign('https://myapp.com', 30);
// => The generated url will be valid for 30 seconds
This will output a URL that looks like https://myapp.com/?expires=xxxx&signature=xxxx
.
Imagine mailing this URL out to the users of your application. When a user clicks on a signed URL your application can validate it with:
// returns `true` if valid, `false` if not
$urlSigner->validate('https://myapp.com/?expires=xxxx&signature=xxxx');

The package can installed via Composer:
composer require spatie/url-signer
A signer-object can sign URLs and validate signed URLs. A secret key is used to generate signatures.
use Spatie\UrlSigner\Sha256UrlSigner;
$urlSigner = new Sha256UrlSigner('mysecretkey');
Signed URLs can be generated by providing a regular URL and an expiration date to the sign
method.
$expirationDate = (new DateTime())->modify('10 days');
$urlSigner->sign('https://myapp.com', $expirationDate);
// => The generated url will be valid for 10 days
If an integer is provided as expiration date, the URL will be valid for that amount of seconds.
$urlSigner->sign('https://myapp.com', 30);
// => The generated URL will be valid for 30 seconds
To validate a signed URL, simply call the validate()
method. This will return a boolean.
$urlSigner->validate('https://myapp.com/?expires=1439223344&signature=a479abde194d111022a6831edbda29b14e7bdb760438a8a0be2556cd1a6c23fa');
// => true
$urlSigner->validate('https://myapp.com/?expires=1439223344&signature=a479abde194d111022a6831edbda-INVALID-29b14e7bdb760438a8a0be2556cd1a6c23fa');
// => false
This packages provides a signer that uses SHA256 to generate signature. You can create your own
signer by implementing the Spatie\UrlSigner\Contracts\UrlSigner
-interface. If you let your signer extend
Spatie\UrlSigner\AbstractUrlSigner
you'll only need to provide the createSignature
-method.
The tests can be run with:
composer test
To get started quickly in Laravel you can use the spatie/laravel-url-signer package.
