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');
```

Install
-------

[](#install)

The package can installed via Composer:

```
$ composer require patieru/url-signer

```

Usage
-----

[](#usage)

A signer-object can sign URLs and validate signed URLs. A secret key is used to generate signatures.

```
use Patieru\UrlSigner\MD5UrlSigner;

$urlSigner = new MD5UrlSigner('mysecretkey');
```

### Generating URLs

[](#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

[](#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
----------------------

[](#writing-custom-signers)

This packages provides a signer that uses md5 to generate signature. You can create your own signer by implementing the `Patieru\UrlSigner\UrlSigner`-interface. If you let your signer extend `Patieru\UrlSigner\BaseUrlSigner` you'll only need to provide the `createSignature`-method.

Tests
-----

[](#tests)

The tests can be run with:

```
$ vendor/bin/phpspec run

```

\##Integrations To get started quickly in Laravel you can use the [patieru/laravel-url-signer](https://github.com/patieru12/laravel-url-signer) package.
