Today, I learned that you can encrypt the data using in a queued job in Laravel:

Encrypted Jobs

Laravel allows you to ensure the privacy and integrity of a job's data via encryption. To get started, simply add the ShouldBeEncrypted interface to the job class. Once this interface has been added to the class, Laravel will automatically encrypt your job before pushing it onto a queue:

use Illuminate\Contracts\Queue\ShouldBeEncrypted;
use Illuminate\Contracts\Queue\ShouldQueue;

class UpdateSearchIndex implements ShouldQueue, ShouldBeEncrypted
{
    // ...
}
