Hi Everybody,
I have a problem on updating a secured segment of the Card. I am
using the gemplus-service-0.1-package and the card is MPCOS-EMV.
I can't update coz i don't know the correct way of giving the requirments
(secret Code, computing the CRYCKS , etc) before the card can be updated.
I tried to compute the CRYCKS using the method
CryoptoUtils.computeCRYCKS(byte[] APDU, SecretKeySpec sessionKey) but I
failed coz it thows an exception.
This is the code
//
tempAdminkey is the temporary admin key generated by the MPCOS APDU
'SelFk' and 'GetResp'
try{
crycks = CryptoUtils.computeCRYCKS( apdu , new
SecretKeySpec(tempAdminKey,"TripleDES"));
}catch(InvalidKeyException
ike){System.out.println(ike.getMessage());
eke.printStackTrace();
}catch(GeneralSecurityException
gse){System.out.println(gse.getMessage());
gse.printStackTrace();
}
return updateFile(apdu, crycks); // sending the apdu command + the
cycks
}
Exception...
/**
Exception in thread "main" java.lang.ExceptionInInitializerError:

Any examples or help is greatly appreciated.
Thanks & Regards,
