spatie / Url Signer
Projects that are alternatives of or similar to Url Signer
Create secured URLs with a limited lifetime
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 days
This will output an 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:
$urlSigner->validate('https://myapp.com/?expires=xxxx&signature=xxxx');

Installation
The package can installed via Composer:

Usage
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');
Generating URLs
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 days.
$urlSigner->sign('https://myapp.com', 30);
// => The generated url will be valid for 30 days
Validating URLs
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
Writing custom signers
This packages provides a signer that uses md5 to generate signature. You can create your own
signer by implementing the Spatie\UrlSigner\UrlSigner-interface. If you let your signer extend
Spatie\UrlSigner\BaseUrlSigner you'll only need to provide the createSignature-method.
Tests
The tests can be run with:
$ vendor/bin/phpspec run
Integrations
To get started quickly in Laravel you can use the spatie/laravel-url-signer package.
