Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers. Chilkat2 Java

import com.chilkatsoft.chilkat2.Cert;
import com.chilkatsoft.chilkat2.ChilkatException;

public class ChilkatExample {

    public static void main(String[] args) {
        Cert cert = new Cert();

        // If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
        cert.setSmartCardPin("12345678");

        // To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
        // When testing in this way, it's best to have only a single smartcard or token connected to the system.
        try {
            cert.loadFromSmartcard("");
        } catch (ChilkatException e) {
            System.out.println(e.getLastErrorText());
            System.out.println("Certificate not loaded.");
            return;
        }

        // The LastErrorText property on all Chilkat objects will contain
        // information even when the method call is successful.
        // You can examine the LastErrorText to see what Chilkat found and
        // what decisions were made.
        //
        // For example, if a certificate was successfully loaded via LoadFromSmartcard,
        // but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
        // then we would want to examine the LastErrorText from the call to
        // LoadFromSmartcard to get detailed information about the card.
        System.out.println(cert.getLastErrorText());

        System.out.println("Found: " + cert.getSubjectDN() + " serial=" + cert.getSerialNumber());
