Integrate MasterCard MasterPass wallet service

[dligthart]

1. Checkout method (add masterpass button)
2. Under proceed button in cart totals add masterpass button
3. Have a review order page instead of normal checkout page
4. Be able to configure via admin settings

Using EMS form with special settings to access the wallet e.g calculate hashExtended.

Reminder; No direct integration with masterpass. Use EMS gateway.

Concept Information Flow:

GUI Changes:

you need to include the following fields in the post form to IPG.

• hash_algorithm: SHA1
• oid: C-445e6e5d-2a32-428f-bcbc-13a6b2fad41a
• currency: 978
• subtotal: 13.99
• shipping: 0
• vattax: 0
• chargetotal: 13.99
• transactionId: 84514035130 (the guide said to include IPGtransactionid which is a mistake).
• hashExtended: (the hash you calculated)

However, in order to calculate hash extended, you should not include transactionID (the guide did not mention it at all! sorry about that).

So for the example above the stringToHash should be: 13.99978SHA1C-445e6e5d-2a32-428f-bcbc-13a6b2fad41a013.990SHAREDSECRETE
