Azure Key Vault is not new to Azure developers and architects. It is a cloud-based service to safeguard your sensitive information and crypto implementation and management . Working with Azure Key Vault can be done via Azure Portal, PowerShell or corresponding client libraries. While people may prefer using a specific library (.e.g Azure Key Vault .NET client), I’d prefer practicing with REST API and HttpClient.
Inspired by unclear instruction on using Azure Key Vault REST API, this article is the result of my practice on the REST API and also found some notes around it.
