Apple Pay JS

[sairaut]

Hi Cheng,

I am using Apple pay JS to integrate Apple pay on my website and NOT app. I have managed to get the merchant validated and on session.onpaymentauthorized event i am receiving the payment token

`session.onpaymentauthorized = function (event) {

            // Get the payment data for use to capture funds from
            // the encrypted Apple Pay token in your server.
            var token = event.payment.token.paymentData;`

Can you please explain how i can decrypt the token using your code? I see that you have test method as below:

`public void InitCompatibleTest()
        {
            var decrypter = new ApplePayTokenDecrypter();
            var p = new ApplePayParameters
            {
                //EphemeralPublicKey = "dGVzdA==",
                EphemeralPublicKey = "",
                PrivateKey = "dGVzdA=="
            };
            decrypter.Init(p);

            Assert.AreSame(p, decrypter.PaymentParameters);
        }`

I have the same question - more specifically about PrivateKey, what is the source of value for this property.
I hope this is not just one time throwaway, unsupported piece of code.

Thanks, Rad

Check out read me file or the home page of this project. There are steps on how to get the private key.

This is how you decrypt the apple pay token

string signature = "obtain from the payment data";
string encryptedData = " obtain from the payment data";
var decrypter = new ApplePayTokenDecrypter();
var p = new ApplePayParameters
{
MerchantIdentifier = "whatever you used to generate the merchant cert from apple portal",
EphemeralPublicKey = " obtain from the payment data",
PrivateKey = "read me instructions"
};
decrypter.Init(p);
string decryptedData = decrypter.Decrypt(encryptedData, signature);
