i understand how calculate a cvv with the source code for masters and visa but i don't understand the CVK pairs. Can you give more insight about cvk pair and if possible state the cvk pair for both visacard and mastercard. This is being used for project
I also did try some readup on it and i come up with this CVKA: B'0010'CVKB: B'0011' is there any other parameter missing from this. http://www-03.ibm.com/security/cryptocards/pdfs/bs327.pdf
Kindly explain more about the cvk pairs and be precise about what the pairs are.
