Generate a url with an expiration date and signature to prevent unauthorized access
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 MD5UrlSigner('randomkey'); $urlSigner->sign('https://myapp.com', 30); // => The generated url will be valid for 30 seconds
This will output an URL that looks like
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\Md5UrlSigner; $urlSigner = new Md5UrlSigner('mysecretkey');
Signed URLs can be generated by providing a regular URL and an expiration date to the
$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=2d42f65bd023362c6b61f7432705d811'); // => true $urlSigner->validate('https://myapp.com/?expires=1439223344&signature=2d42f65bd0-INVALID-23362c6b61f7432705d811'); // => false
This packages provides a signer that uses md5 to generate signature. You can create your own
