Configure Azure Key Vault
To create an Azure Key Vault, follow these steps:
Navigate to Key Vaults under Home (use Search to find Key Vaults).
Create a new Key Vault with name/resource group/location and a new access policy with keys permissions (decrypt and encrypt) and principle (your newly created VM).
Under Settings navigate to Keys, and generate new keys for data/config/logs encryption. Use these keys IDs to configure MarkLogic Server encryption.
