Seeking crypto feedback on a web payments proposal

Dear Web Security IG,

Over in the Web Payments Working Group we are developing a proposal [1] to improve the
security of payments on the Web by facilitating the encryption of sensitive data the flows
through the Payment Request API. To summarize the proposal:

 * The merchant invokes Payment Request API and passes a reference to a key provider.
 * When the user selects a payment method, the application used to make the payment
   encrypts the response data using this key.

The proposal [1] calls out some of the use cases for this general approach to encryption
of response data.

While the proposal has received cursory review (which has been helpful), we have not
had deeper review by crypto experts / implementers. For that reason, I am writing to the IG
to see if there is anyone interested in working with us to figure out how to bring encryption 
to the Payment Request ecosystem.

Thank you,

Ian
