func chilkatTest() {
    let cert = CkoCert()

    // The certificate must originate from a source where the private key material is available to be included
    // in the upload to Azure Key Vault.

    var success: Bool = cert.LoadPfxFile("qa_data/pfx/myCert.pfx", password: "pfx_password")
    if success == false {
        print("\(cert.LastErrorText)")
        return
    }

    let json = CkoJsonObject()

    // Indicate this request is to upload to Azure Key Vault.
    json.UpdateString("service", value: "azure-keyvault")

    // Provide your OAuth2 client credentials for your Azure App (service principal) that has
    // the required Role-Based Access Control (RBAC) permissions.
    json.UpdateString("auth.client_id", value: "APP_ID")
    json.UpdateString("auth.client_secret", value: "APP_PASSWORD")
    json.UpdateString("auth.tenant_id", value: "TENANT_ID")

    // Indicate the key vault name
    json.UpdateString("vault_name", value: "VAULT_NAME")

    // When you import a certificate into an Azure Key Vault, the certificate name and vault name are included as 
    // parts of the URL to specify the target location where the certificate should be stored. 
    // The URL follows a specific format to identify the target Key Vault and the certificate within it. 
    // Here's how the certificate name and vault name are incorporated into the URL:
    // https://VAULT_NAME.vault.azure.net//certificates/CERT_NAME/import?api-version=7.4

    // Specify an arbitrary certificate name, but one that can be used in a URL as shown above.  (i.e. alphanumeric with no SPACE chars)
    json.UpdateString("cert_name", value: "CERT_NAME")

    // Add optional tags if desired. Tags can be anything you want.   
    json.UpdateString("tags.serial", value: cert.SerialNumber)
    json.UpdateString("tags.issuer", value: cert.IssuerCN)
    json.UpdateString("tags.subject", value: cert.SubjectCN)

    // OK.. everything is specified.  Simply call UploadToCloud.
    let jsonOut = CkoJsonObject()
    jsonOut.EmitCompact = false
    success = cert.UploadToCloud(json, jsonOut: jsonOut)
    if success == false {
        print("\(cert.LastErrorText)")
        print("\(jsonOut.Emit())")
        return
    }

    // Success!  Go to the Azure portal and refresh to see the certificate has been uploaded.
    // The jsonOut provides the JSON response from the Azure server.
    print("\(jsonOut.Emit())")
    print("Success")

    // Here is sample jsonOut
