However, it can sometimes be useful, such as during local development, for the Reverb server to handle secure connections directly. If you are using [Laravel Herd](https://herd.laravel.com) and have secured the site or you are using [Laravel Valet](/docs/{{version}}/valet) and have run the [secure command](/docs/{{version}}/valet#securing-sites) against your application, you may use the Herd / Valet certificate generated for your site to secure your Reverb connections. To do so, set the `REVERB_HOST` environment variable to your site's hostname or explicitly pass the hostname option when starting the Reverb server:

php artisan reverb:start --host="0.0.0.0" --port=8080 --hostname="laravel.test"

Since Herd and Valet domains resolve to localhost, running the commmand above will result in your Reverb server being accessible via the secure WebSocket protocol (wss) at `wss://laravel.test:8080`.

You may also manually choose a certificate by defining `tls` options in your application's `config/reverb.php` configuration file. Within the array of `tls` options, you may provide any of the options supported by [PHP's SSL context options](https://www.php.net/manual/en/context.ssl.php):
