Reply To: Help with authentication on DESFireEV1 card

[Mats Paulin]

Thanks for the reply Christian.

As can be seen in the initial post I used this method for selecting the application.

_objDESFireEV1.selectApplication( 6 );

Then I did an authentication using the following method.

_objDESFireEV1.authenticate( 0, IDESFireEV1.AuthType.AES, KeyType.AES128, keyData);

Is that not enough or the correct way to do this?

Error message I get is thrown when trying to authenticate with the code above.

Data is stored something like this.

Application	File	Key

X		A	112233AA112233AA112233AA

X		B	445566BB445566BB445566BB

X		C	778899CC778899CC778899CC

Is it possible to authenticate with different keys for the same application in order to access the different files stored there?
