Hi, everyone. I'm very new to developing for PayPal, and have a two fairly straightforward questions that their documentation does not explicitly answer. My Goal: To send encrypted cart contents (price, amount, etc.) to PayPal for payment processing. I want to use PayPal's payment form. The cart upload command looks to be the closest fit, and would require I send "cmd=_cart" and "upload=1" as control variables that define the transaction. Question 1: Is it possible to encrypt the form variables -- specifically, the amount and price values -- when doing this type of submission to PayPal? I assume that it is not, based on what I've read, though this is not stated explicitly, and the page I linked to before, which details this method, implies that you can in fact encrypt the data: "Securing Your Shopping Cart After you have customized you third party shopping cart, protect against malicious users tampering with the button code and submitting an incorrect charge by using one of the methods described in Securing Your Website Payments Standard Buttons." Question 2: If I can't encrypt the form variable values, then can I use the PayPal Button API to dynamically create a "checkout" button in order to send the cart information in an encrypted form?
