Re: [webpayments] How are payment messages trusted? (#19)

Some elements in the payment response may need to be hidden from the merchant also (e.g. card number), so signatures don't meet this requirement. Since we are creating other connection from the browser, e.g. to cloud payment instruments, couldn't the connection to the PSP be via the same means? My view is we may need to support both methods.
