handle 20bytes cryptogram for amex card #10

Closed cafedood closed 8 years ago

cafedood commented 8 years ago

Both cyberSource ApplePay & cyberSource AndroidPay are using the same way to handle amex card 

Step 3 Set the ccAuthService_cavv field to the 3D Secure cryptogram of the payment network token.
 Include the whole 20-byte cryptogram in the ccAuthService_cavv field. For a 40-byte cryptogram, split the cryptogram into two 20-byte binary values (block A and block B). Set the ccAuthService_cavv field to the block A value and set the ccAuthService_xid field to the block B value.

Add it to support 20-byte cryptogram

@pierre pls take a look :)
