    boolean success = false;

    CkCert cert = new CkCert();

    success = cert.LoadFromFile("qa_data/certs/someCert.pem");
    if (success == false) {
        System.out.println(cert.lastErrorText());
        return;
        }

    // Get the certificate's public key:
    CkPublicKey pubkey = new CkPublicKey();
    cert.GetPublicKey(pubkey);

    System.out.println(pubkey.getPem(false));

    // OK.. we have the public key which can be used in other Chilkat classes/methods...
