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

    // The bootstrap secret will contain the following information:

    // IBM Cloud API Key

    // See following examples for setting up a bootstrap secret in memory, 
    // or in the local manager (Windows Credentials Manager or Apple Keychain)
    // Setup Bootstrap Secret in Local Manager
    // Setup Bootstrap Secret in Memory
    let bootstrap = CkoSecrets()!

    // Set the location of the bootstrap secret.
    // Can be "local_manager" or "memory", depending on how you setup the bootstrap secret.
    // ---------------------------------------------------------------------------------------------
    // If your operating system is NOT Windows or MacOS/iOS, then change "local_manager" to "memory"
    // You can also, if desired, use "memory" on Windows and MacOS/iOS if your bootstrap secret was previously setup in memory.
    // ---------------------------------------------------------------------------------------------
    bootstrap.location = "local_manager"

    // Specify the bootstrap secret to be used.
    let bsId = CkoJsonObject()!
    bsId.update("appName", value: "ibm_bs")
    bsId.update("service", value: "Example")
    bsId.update("username", value: "Joe")

    // ----------------------------------------------------
    let secrets = CkoSecrets()!

    // Setup for the IBM Cloud Secrets
    secrets.location = "ibm_cloud"
    var success: Bool = secrets.setBootstrapSecret(bsId, secrets: bootstrap)
    if success == false {
        print("\(secrets.lastErrorText!)")
        return
    }

    // Specify the secret to be fetched.
    let json = CkoJsonObject()!
    json.update("appName", value: "Test2")
    json.update("service", value: "Custom")
    json.update("domain", value: "Ocean")
    json.update("username", value: "Starfish")

    // You'll also need to specify your IBM Cloud instance ID and region for each API call.
    json.update("instance_id", value: "a88a0c56-50a6-4461-9911-345b173e1171")
    json.update("region", value: "us-south")

    // Get the binary secret data.
    let bd = CkoBinData()!
    success = secrets.getSecretBd(json, bd: bd)
    if success == false {
        print("\(secrets.lastErrorText!)")
        return
    }

    // For our testing, the binary secret was a JPG image..
    bd.writeFile("c:/temp/qa_output/starfish.jpg")

    print("Success.")
