Secure your Environment Variable inside Azure Function using Key Vault.

In the previous blog, we learn about how to use the Environment variable in Azure Function. Environment variables are most important and confidential as they might contain the system credentials or configure that you don’t want any to access directly. The most unsecure way to store them is directly inside the Configuration of Azure function so in this blog we will see how to store the Environment variable inside the Key Vault and use the Key Vault reference in Configuration.

You can create an Azure function and use Environment Variable to do so do refer to my previous blog:

Step 1: Create a Key Vault

Login to Azure Portal and click on + Create a resource called “Key Vault”.

Click on Create

You can create a new resource group or select the existing group based on your preference. (You can create all resources related to a single project in one resource group so that it will easier to manage resources project wise)
