title: Where to store the decryption key in reactjs?
body: <p>I am working on react app which fetches the API on the user responses. 
  API response are encrypted and I get decryption key before making any API (via secure method). </p>
  
  <p>I need to store the decryption key so that I can decrypt the API response every single time.
  Currently I store the decryption key in component state. 
  which can be seen very easily by anyone using react-dev tool</p>
  
  <p>I don't need to store the decryption locally, it changes very time user login.</p>
