@Sudesh Sharma Thank you for your query.Azure App Service provides a highly scalable, self-patching web hosting service. This article shows you how to create, upload, or import a private certificate or a public certificate into App Service.
Once the certificate is added to your App Service app or function app, you can secure a custom DNS name with it or use it in your application code.
You can refer to this article to get more details.
These TLS/SSL certificates can be stored in Azure Key Vault, and allow secure deployments of certificates to Windows virtual machines (VMs) in Azure.
To learn more on how to Secure a web server on a Windows virtual machine in Azure with TLS/SSL certificates stored in Key Vault you can refer to this article as well.
Hope it helps!!!
