Create secured URLs with a limited lifetime

Latest Version on Packagist Software License Build Status Quality Score Total Downloads

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.
