Hi,

do you have any idea how long its last to solve(approximately). Would be an useful info for me. So i can adapt the time line for our project with our customer.

Greetings&Thanks

Here my code:

desFireEV1.selectApplication(4726016);

desFireEV1.authenticate(1,IDESFireEV1.AuthType.AES,KeyType.AES128,objKEY_AES128);

String auth = desFireEV1.getAuthStatus();

IDESFireEV1.CardDetails details = desFireEV1.getCardDetails();

rd =   desFireEV1.readData(1, 0, 16, IDESFireEV1.CommunicationType.Enciphered,1024);

AppId: 4726016
Key: id 1 , type: reading key


like i wrote before I'm stuck with reading the data,I thought it should straight forward but I'm getting different values each time I try to read the same card.
Isn't the result of readData() decrypted after the Authentication was successful?
And I'm getting an com.nxp.nfclib.exceptions.InvalidResponseLengthException: Authentication Error when I'm using the Method getFileIDs() after succeccful authentication (auth = AES).

Aditional infos:

I try do read data from an application which is not the application 0 with an reading key.

Hi,

found out by myself on the weekend.
thanks.

So in the moment I'm stuck with reading the data,I thought it should straight forward but getting different values each time I try to read a card.
Isn't the result of readData() decrypted after the Authentication was successful?
And I'm getting an com.nxp.nfclib.exceptions.InvalidResponseLengthException: Authentication Error when I'm using the Method getFileIDs() after succeccful authentication.

Hello,

having still a problem with authentication.
When calling method authenticate following error occures:

com.nxp.nfclib.exceptions.InvalidResponseLengthException: Authentication Error

      desFireEV1.selectApplication(0);



            byte[] KEY_AES = new byte[] {

                    (byte) 0xAA,(byte) 0xAA,(byte) 0xAA,(byte) 0xAA,(byte) 0xAA, (byte) 0xAA,(byte) 0xAA,(byte) 0xAA,

                     (byte) 0xFF,(byte) 0xFF, (byte) 0xFF,(byte) 0xFF,(byte) 0xFF,(byte) 0x5F, (byte) 0xFF,(byte) 0xFF,



            };



           Key key = new SecretKeySpec(KEY_AES,"AES");

           KeyData keyData = new KeyData();

           keyData.setKey(key);

          desFireEV1.authenticate(0, IDESFireEV1.AuthType.AES, KeyType.AES128, keyData);

Need help!!!

Hi,

thanks for the hint with the sdk version.
But after changing the version I'm getting the following error:

com.nxp.nfclib.exceptions.InvalidResponseLengthException: Incomplete response

with the same code at desFireEV1.selectApplication(1) or desFireEV1.getApplicationIDs();

Hello,

yes I'm using the TapLinx SDK. I'm providing a little bit more of my code. Just changed the key value for this post.
The error (error:0606508A:digital envelope routines:EVP_DecryptFinal_ex:data not multiple of block length)
occurs at the all of the authenticate method.

I'm testing on a Samsung Galaxy s5 mini(SM-G800F) with android 5.1.1

mCardType = CardType.DESFireEV1;
desFireEV1 = DESFireFactory.getInstance().getDESFire(m_libInstance.getCustomModules());

try {

desFireEV1.getReader().connect();
desFireEV1.getReader().setTimeout(2000);
desFireEV1.selectApplication(1);

byte[] KEY_AES = {
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,
(byte) 0x00,

};


Key key = new SecretKeySpec(KEY_AES, "AES");
KeyData keyData = new KeyData();
keyData.setKey(key);
desFireEV1.authenticate(0, IDESFireEV1.AuthType.AES, KeyType.AES128, keyData);
showMessage("authenticated", 't');


} catch (NxpNfcLibException ex ){
showMessage(ex.getMessage(),'t');
}
break;
