How to use Java Card

Discussion in 'Java' started by Susanne Kaufmann, Apr 26, 2007.

  1. Hello,

    I have a java application encrypting/decrypting files and messages. At
    the moment I read the privateKey (for file-encryption I use AES and
    wrap the key with a public RSA key) from a textfile. Now I would like
    to put the key on a IBM JCOP 31 Smartcard.

    But here I have got a few questions. At first I would like to use the
    card to verify the user to the application. E.g. the application
    starts and the user is asked to insert his smartcard and then to enter
    the pin using the card readers pinpad. How could I realise this?

    The second problem is, how to transport the private key from the card
    into the application. I thought using this way: my application
    generates a private/public keypair. Then the publicKey is sent to the
    smartcard, which wraps its own privatekey with it. this wrapped key is
    sent back to the application.

    Greetings,

    Susanne
