Key Vault (Implementing Secure Data by setting up Always Encrypted)

You have been asked to create a proof of concept application that makes use of the Azure SQL Database support for Always Encrypted functionality. All of the secrets and keys used in this scenario should be stored in the key vault. The application should be registered in Azure Active Directory (Azure AD) in order to enhance its security posture. To accomplish these objectives, the proof of concept should include:

Creating an Azure key vault and storing keys and secrets in the vault.
Create a SQL Database and encrypting content of columns in database tables by using Always Encrypted.
