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

    // The Chilkat PEM class was introduced in v9.5.0.49.  
    // It requires the bundle to be unlocked, as shown above.
    let pem = CkoPem()!

    // Add the private key found in alice.key to this PEM.
    // 
    let privKey = CkoPrivateKey()!

    // Write the PEM containing the private key and certificate.
    // The private key will be output in PKCS8 encrypted form.
    // Certificates are never encrypted.

    // This is the password that will be required to open and access the private key
    // from the PEM we're about to write..
