Does Azure Key-Vault encrypt the values before storing?

Question

We are using key-vault for storing the secrets, will it give any added advantage if we encrypt the values before storing it in key-vault?

Answer 1

You don't make clear exactly how you intend using Key-Vault.

As a general guide to encryption you should always ask the question, "Who has the keys?"

Many storage services offer to perform encryption for you, but if the encryption is not with your keys, it's not your protection.
