Hello all,
There is a bug/feature in the CardID constructor of OCF 1.1.
When the inserted card is f.e. a memory card with a synchronous ATR that
does not conform to ISO 7816, the constructor in CardID hangs up.
This could easily be fixed to support other ATRs by not retrieving the
historical bytes when ATR is non-conformant :
-----------------
public CardID (byte[] answerToResetResponse)
throws CardTerminalException {
atr = (byte[]) answerToResetResponse.clone();
// ... assert minimum length: TS + T0 character must be present
if (atr.length < 2)
throw new CardTerminalException
("Illegal ATR response (length " + atr.length +
" < 2): " + HexString.hexify(answerToResetResponse));
// FIX
// THIS OUTER "if" ADDED BY CARLES BARROB�S
if ((atr[0] == 0x3B) || (atr[0] == 0x3F)) // check if ISO
asynchronous ATR
{
// ENDFIX
if ((atr[1] & 0x0f) > 0)
{
historicals = new byte[atr[1] & 0x0f];
// retrieve the historical bytes
System.arraycopy(atr, atr.length - 1 - historicals.length,
historicals, 0,
historicals.length);
int histCtr = historicals.length-1;
}
// FIX
}
// ENDFIX
}
---------------
The program I am designing right now is called CardInfo. It gives me as much
info as possible of the chip by identifying the ATR and other features based
in a "InfoCardService". I am planning to support memory cards (at least ATR
retrieval), therefore I had to introduce the mentioned fix. Could this type
of fix be added to further releases of OCF?
Thanks,
C A R L E S
