Encrypting local cookies

Hi We're testing a new switcboard solution. It uses a webpage that stores a cookie on clients with information that we want to be encrypted.

Found an option in the http profile and another iRule option, but both options require a cookie-name. These cookies comes with different names depeding on the client that receives it, so I wonder if it was possible to encrypt all cookies.

This is not the same as secure cookie response, in this case we want to actually encrypt the cookie stored on clients with a passphrase.
