title: How to secure the fastlane json key file used for uploading the google play store
body: <p>How can I encrypt/pass the JSON key file used by Fastlane to upload my apps to the app store?</p>
  
  <p>Seems the current solution is to keep the key.json in the repo itself and mention the path in the Fastfile.</p>
  
  <pre><code>json_key_file("../key.json") # Path to the json secret file - Follow https://docs.fastlane.tools/actions/supply/#setup
  </code></pre>
  
  <p>What would be a better alternative?</p>
