Let me give you a clear thinking: - Create new Class, but don't extend Applet, let it called Library Class. - Generate jar, exp and cap of this library class. Case example: - You can have 2 applet, for example Applet A & B. - Applet A can use the API (common code/method) from the Library Class b...

Are your two applets in the same package or in the separate package?

From your code, it looks like you are copying the input data into cardMetaData buffer and copying back to the global buffer. And last line in your function 'updateCardMetaData' you are trying to return the length bytes of data(128B) which is why you are getting 0x6C80. If you don't expect any data i...

What should the three keys be set to? The three keys you set should be as same as the keys of your java cards. As per GP specification said, the three keys of cards are 404142434445464748494A4B4C4D4E4F by default. You can set the keys via pyAPDUTool. Switch to "Util" tab and select "...

Please note that all you can change are the "Historical Bytes". The first (I think) 6 bytes are hardware settings. Trying to change those *will* brick your card. As @ ThePhoenyx said, You can only change the historical bytes via a default selected application. There is no way to change th...

Could you please tell us more about your applet? And on which interface are you trying to communicate with the card? contact or contactless?

Could you please show us your "DELETE" APDU command? I think that your command may have something wrong.

You can't know the exact value because it depends on how the card is implemented internally. Usually it's a tiny bit smaller than the size of load block.

Maybe the code below will be helpful to you. public RSAEncDec(byte[] bArray,short bOffset,byte bLength){ outbuffer = new byte[128]; inbuffer = new byte[64]; cipherENC = Cipher.getInstance(Cipher.ALG_RSA_PKCS1, false); cipherDEC = Cipher.getInstance(Cipher.ALG_RSA_PKCS1, false); rsaPrivateKey = (RSAP...

Hi there!

If appropriate, could you tell me what is your purpose of cloning the card?
