* I do not have encryption keys. You are to use the information I have including PAN, EXP DATE, AND CVV1 (aka PVV) to find the Key(s)1/2 necessary to find future PVV with the newly found keys.
Simply backtrace to find Keys.
Correction: here is the link: http://www.paymentcardtools.com/card-security-values
I will give you the "Security Value" it's the correct confirmed 3-digit code.
You will then determine the CVKa and CVKb.
(essentially the opposite of what this calculator does)
