Access Azure Key Vault Using Service Principal C#: A Step-by-Step Guide

To access Azure Key Vault using a service principal in C#, you'll need to register your application in Azure AD.

First, create a new Azure Active Directory (AAD) application to represent your service principal.

In the Azure portal, navigate to Azure Active Directory > App registrations, and click New application to start the process.

You'll need to provide a name and redirect URI for your application, which will be used for authentication.

The redirect URI is the URL that Azure will redirect the user to after authentication.

Make sure to choose the correct platform (Web, Mobile, or Desktop) and provide a valid redirect URI.

For a C# application, the redirect URI will typically be the URL of your application's login page.

To register an application for Azure Key Vault access, you'll need to create a new app registration in Azure Active Directory. Go to https://portal.azure.com/ and navigate to the Azure Active Directory section.

The next step is to click on the "App Registrations" section and then click on "New Registration".

You can name your app registration as you like, such as "abp.io-vault" as mentioned in the example.

This will create a new application registration in Azure AD, which you'll need for the next steps in accessing Azure Key Vault using a service principal in C#.

A unique perspective: How to Create a Service Principal in Azure

To grant access to Azure Key Vault, you need to grant permissions to read Key Vault Secrets to your Managed Identity. This is a crucial step that ensures your Service Principal can access the secrets.

First, you need to grant access to your Managed Identity. You can do this by following the instructions in the Azure portal.

Granting permissions to your Managed Identity will allow it to read Key Vault Secrets, making it possible to access Azure Key Vault using a Service Principal in C#.

To access Key Vault, you'll need to grant permissions to read Key Vault Secrets to your Managed Identity. This is a crucial step to ensure seamless integration.

You can use a Service Principle to access Azure Key Vault secrets, but to list all secrets in the Key Vault, you'll need to use a specific method. This is where things can get a bit tricky, but don't worry, we've got you covered.

First, create an app service plan in the resource group defined earlier and assign the Service Identity to it. This will enable your app to access Key Vault securely.

To list all secrets in a Key Vault using a Service Principle, you'll need to use a C# Web API. This will allow you to display a list of available secrets for the developer to choose from.

Remember to use a Service Principle to access Key Vault secrets, as this will provide the necessary permissions and authentication.

Managed Identities simplify handling secrets for Azure services, never storing credentials in code or config, and supporting development and production. This solution is integrated with many Azure Services.

To access Azure Key Vault, you'll need to create a Managed Identity, which can be done by registering an application in Azure. This Managed Identity will then be used to access Key Vault.

Here are the key benefits of Managed Identities:

To create a service principal, you'll need to register an application in Azure. This is a crucial step in using Managed Identities.

The most important aspect of service principals is that they're used to create access policies for Azure services, including Key Vault.

In Azure, you can register an application by going to the Azure portal, searching for "Registered applications", and clicking on "New application".

To create a service principal, you'll need to provide some basic information about the application, such as its name and redirect URI.

Here's a quick rundown of the information you'll need to provide:

After registering the application, you'll need to create a client secret. This is a random string that will be used to authenticate the application.

In the Azure portal, go to the "Certificates & secrets" section of your application and click on "New client secret". Give the secret a name and click on "Add".

Managed identities for Azure resources is the new name for the service formerly known as Managed Service Identity (MSI), which simplifies handling secrets for Azure services.

It's a way to handle secrets for Azure services including Key Vault, without storing credentials in code or config.

The solution is integrated with many Azure Services, making it a convenient option for development and production.

Here are the key benefits of using managed identities:

Granting access to Azure Key Vault is also a crucial step, as mentioned in another article section, where we should not forget to grant permissions to read Key Vault Secrets to our Managed Identity.

To create an Azure Key Vault, you'll need to sign in to the Azure portal and search for "Key vaults" in the directory. Then, click Add to create a new key vault.

You'll need to fill out a form to create the key vault storage. After creating the key vault, navigate to its details and create a new secret named VerySecretValue.

To use the key vault with a web app, you'll need to create an app service plan in the same resource group, and assign a Service Identity to it. This is where things get interesting, as we'll explore how to connect your web app with the key vault in the next steps.

To upload a certificate to Azure, go to Azure Active Directory and then app registrations. Select the app you have registered before.

You'll need to go to "Certificates & secrets" and click the "Upload certificate" button. This will allow you to upload the certificate you've exported before.

After uploading the certificate, Azure will generate a Thumbprint value. This value will be used in your ASP.NET Core app.

To connect your web app to a Key Vault, you'll need to get the ID of your web app's service principal. This is where things get interesting - you'll be using a Service Principle to access your Key Vault.

First, create an app service plan in the resource group defined earlier and assign the Service Identity to it. This will give your web app the necessary permissions to interact with your Key Vault.

Next, create a Key Vault to use with your web app. You can do this by creating a new resource in your Azure portal, or by using the Azure CLI.

Once you have your Key Vault set up, you can use a Service Principle to access its secrets. This is a more secure way to manage access to your Key Vault, and it's a great way to give your web app the permissions it needs without having to hard-code any credentials.

To access all the secrets in your Key Vault, you can use a C# Web API and a Service Principle. This will allow you to list all the secrets in your Key Vault, making it easier for developers to use the correct one.
