In this article, we will learn how to create the self-signed X.509 device test certificate for Azure IoT Hub Device Provisioning Service and Azure IoT Hub which can be helpful during the development instead of relaying on the real certificate.
What is use of X.509 Certificate?
How To Create X.509 Test Certificates locally?
During the IoT application development we need the X.509 certificates for those devices which are depends on the X.509 based authentication. The developer test many scenarios during the development, so every time buying the new certificate and device for development is not possible, so we required something virtual but gives a real-life experience, so by considering time and cost, we will create the test certificates locally and test the Azure IoT experience. Microsoft has provided the sample PowerShell script on GitHub to generate the X.509 certificates.
