You can use AlgTest to check if your card support the signature type .

create a Global PIN
I am trying to write an applet which creates a Global PIN. Could somebody tell me the specific steps?
And where is the Global PIN actually stored? In my applet or in the ISD?

My applet returns 16 bytes of 0 instead of AES encrypted value,why?
I am writing a java card applet to encrypt 16 bytes of incoming APDU command data section and return the encrypted value. My code: public class DoAES extends Applet { static Cipher myCipher; static AESKey myAESKey; byte[] cipheredData = JCSystem.makeTransientByteArray((short) 0x10, JCSystem.CLEAR_ON...

which cipher class supports ECC
I have a A22 card and it supports ECC. And I am going to encrypt data using ECC cryptography in my applet.
What i want to know is which cipher class supports ECC.
For RSA cryptography, it can use Cipher.ALG_RSA_PKCS1. What is the similar cipher class for ECC?

Hash table on smart card
As far as i know, there is no hash table on smart card. But now i want to store a hash table containing the terminal configuration. I guess, smart card only stores the configuration , and the terminal sends the instruction to get stored configuration via APDU commands. Am i right ? If yes, how can i...

convert data character string to java array
Every time I process algorithm computation, there is much data to be inputted.
How can I convert data character string to java array quickly ?
Such as "12345678" to 0x12, 0x34, 0x56, 0x78

Hi,UNKNwYSHSA
Thanks for your answer anyway.

Re: How to know supported encryption/sign algorithms in a Javacard
That's so nice of you. But,it takes too long to test all the possible algorithms successively . Is there any method to know all the algorithms supported by the given card at a time ?
