title: secure APP_KEY to further strengthen Encryption in Laravel
body: <p>I am storing sensitive user data in my application.</p>
  <p><strong>Crypt</strong> facade class of <em>PHP Laravel</em> is being used to <em>encrypt/decrypt</em> sensitive data.</p>
  <p><strong>APP_KEY</strong> is at config folder</p>
  <p>Database being used is MySql. Encrypted data is stored at DB</p>
  <p>I want to further strengthen my security at application.</p>
  <p><em>Need suggestions to hide the <strong>APP_KEY</strong> from project, or have it in some encrypted format.</em></p>
  <p>Aim is to keep it secure from getting leaked, so that even the developers do not have access to it .</p>
  <hr />
  <p>Any other tip to further strengthen my encryption is also welcome !</p>
