The iltio package provides helpers to easily add client-side encryption to your application. This way you can guarantee your users that their data is private even from your server.
Client-side Encryption
If you want to keep your authentication token secret it's possible to route the authentication through your server. To do that simply redirect calls by adding the token.
import { encrypt } from 'iltio' const encryptedData = encrypt({ text: 'Hello World' })
