I bought a J3R150 EMV card from Ali Express and want to install my application to the card using GPpro.

I was given the key value by the seller and when I try to actually write the application, I am having trouble with the GP Key error.

Here is the key value I was given.

J3R150 TK :
CDKenc : 90379A3E7116D455E55F9398736A01CA
CDKmac : 473F36161A7F7F60CC3A766EA4BE5247
CDKkek : D3749ED4FF42FD58B39EEB562B017CD9

And this is what happens when I try to get the list of applications on my PC.

I'm inclined to think that perhaps the way I'm setting up the GPpro is not correct.
What should I do?

I assume that by now you have bricked this chip (read again the warning on the wiki page).

gp -ldv --key-enc YYY --key-mac XXX --key-dek FFF with the right keys is what you should have tried first.

Why do you use -key-kdf ?

It was similar to the JCIDE optional software that failed to authenticate. Therefore, we assumed that the processing and procedures performed internally were different.
Also, since it was described as an EMV model, we used -key-kdf in the hope that it would be processed as an EMV.

Thanks.

That is a fragile/wrong assumption.

Please read https://github.com/martinpaljak/GlobalPlatformPro/wiki/Keys#diversification

Unless explicitly said by card vendor, I'd expect three keys to NOT require additional diversification. Do try without it.

First, I ran the command without the --key-kdf option.
I switched between several modes.

I also contacted the card vendor and they said that this is the default key value for NXP.

Thanks for giving lots of advice to a beginner.
