We want to create a standalone HTML5 SPA with sensitive business data. Most likely with knockout.js!
But we do have serious security issues.
What about encryption? Encryption may be possible. But the corresponding key must be on the client side (offline). And if you have both algorithms plus keys on the client side, you can also keep it unencrypted in local storage.
How about data manipulation? Easily manipulate DOM or JavaScript objects with tools like Firebug, etc.
I really like the knockout, but it is not suitable for real business applications.
Any suggestions?
