    // Most of the time a .jks contains one certificate with it's associated private key.
    // (Similar to how a .pfx/.p12 usually contains a particular certificate with private key.)
    // This example demonstrates how to get the certificate with private key such that it can be used
    // by other Chilkat classes wherever a cert w/ private key is needed.
    var jks = new chilkat.JavaKeyStore();
    var password = "secret";
    success = jks.LoadFile(password,"qa_data/jks/test_secret.jks");

    if (jks.NumPrivateKeys < 1) {
        console.log("No private key available.");
        return;
    }

    // -------------------------------------------------------------------------
    // Get the certificate chain associated with the 1st (and probably only) private key in the JKS.

    var chain = new chilkat.CertChain();
    success = jks.CertChainAt(0,chain);

        console.log(chain.LastErrorText);
        return;
    }

    // Verify again that this cert has a private key.
    if (cert.HasPrivateKey() !== true) {
        console.log("Certificate has no associated private key.");
        return;

    // We now have the cert object with it's associated private key, and it can be used in other Chilkat classes where needed.
