I am writing an app for BlackBerry that utilizes a BlackBerry smartcard reader. There is not much documentation on the subject, so I&#39;d really like if someone could give me starting examples.

Basically, there is one RSA private key on the card plus a certificate (for paired public key). I would like to be able to encrypt/decrypt data and also sign it as well. The final goal would be to establish an mutual-authenticated SSL connection using client certificate contained on the smartcard.

Here is the code I managed to come up with so far:

    SmartCardReader btReader = null;
    SmartCardReader[] readers = SmartCardReaderFactory.getInstalledReaders();
    for (int i = 0; i &lt; readers.length; i++) {
        SmartCardReader reader = readers[i];
        if (reader.getType().equalsIgnoreCase(&quot;bluetooth&quot;)) {
            btReader = reader;
            break;
        }
    }
    
    SmartCardReaderSession readerSession = reader.openSession();
    CryptoSmartCard card = (CryptoSmartCard) readerSession.getSmartCard();
    RSACryptoToken token = (RSACryptoToken) card.getCryptoToken(&quot;RSA&quot;);

This `token` looks promising - has some nice methods, but with &quot;cryptic&quot; arguments. What to do next?
