Exporting Data Security Manager keys to Cloud Providers for Bring Your Own Key (BYOK) - Azure Key Vault HSM

Overview

There are several ways to export Fortanix Data Security Manager (DSM) keys to major cloud providers that support BYOK for server-side encryption. This document describes the process for importing HSM-protected keys to Key Vault.

Actions to be performed on Azure

You will need to provide the tool your Azure credentials, which will be used to authenticate to Azure and perform interactions with Azure Key Vault. You can do the following to get these credentials:

1. Log in to https://portal.azure.com/.
2. Register an application. Figure 1: Initiate app registration  Figure 2: Register an App  Figure 3: App registered 
3. Create a client secret for the above application. Figure 4: Client secret for the app 
4. Give the App permission to access the Azure Key Vault. Figure 5: Key Vault permission to access app 
5. Create an Azure Key Vault.
      NOTE: This Key Vault should have a premium subscription. Figure 6: Create Azure Key Vault HSM
