            base64.StdEncoding.EncodeToString([]byte(ownerPassword)),
            encrypt_algorithm,
            args)
        if err != nil {
            fmt.Println(err.Error())
        } else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
            fmt.Println("Unexpected error!")
        } else {
