 The following example uses [OpenSSL](https://www.openssl.org/) and the [OpenSSL Cookbook](https://www.feistyduck.com/library/openssl-cookbook/online/ch-openssl.html) to create a certification authority (CA), a subordinate CA, and a device certificate. The example then signs the subordinate CA and the device certificate into a certificate hierarchy. This example is presented for demonstration purposes only.

 >Microsoft provides PowerShell and Bash scripts to help you understand how to create your own X.509 certificates and authenticate them to an IoT hub. The scripts are included with the [Azure IoT Hub Device SDK for C](https://github.com/Azure/azure-iot-sdk-c). The scripts are provided for demonstration purposes only. Certificates created by them must not be used for production. The certificates contain hard-coded passwords (“1234”) and expire after 30 days. You must use your own best practices for certificate creation and lifetime management in a production environment. For more information, see [Managing test CA certificates for samples and tutorials](https://github.com/Azure/azure-iot-sdk-c/blob/main/tools/CACertificates/CACertificateOverview.md) in the GitHub repository for the [Azure IoT Hub Device SDK for C](https://github.com/Azure/azure-iot-sdk-c).
