    // Note: This example requires Chilkat v9.5.0.66.

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // Create a PEM containing a valid EC private key and certificates.
    // The password for this encrypted PEM is "secret123"
