Re: Problem in sending extended APDU

Refer to this code section: short readCount = apdu.setIncomingAndReceive(); while ( bytesLeft > 0){ // process bytes in buffer[5] to buffer[readCount+4]; bytesLeft -= readCount; readCount = apdu.receiveBytes ( ISO7816.OFFSET_CDATA ); } You need to call receiveBytes to receive the left bytes.

Re: Secure Messaging

The problem is your SELECT command is terminating the secure channel. So perform the select before the secure channel.

Re: javax.crypto.BadPaddingException

Try to replace the following code

Code: Select all

byte[] p = new byte[64];
 
// Encrypt with the public key
cipher.doFinal(s, 0, s.length, p, 0);


with

Code: Select all

// Encrypt with the public key
byte[] p = cipher.doFinal(s);

Re: SELECT command

Your code has told the OS to get ready to send the required data and then keeps executing through to your switch statement which does not understand the INS and throws the appropriate error. Please add a "return" statement after sendBytesLong().
