Asp net core data protection with azure key vault for containerized app deployme

ASP.NET is a popular programming language used for developing web applications. It provides a powerful framework for dynamic and interactive websites. One of the key of ASP.NET is its ability to handle data protection, ensuring the security and integrity of sensitive information.

In this article, we will explore how to use ASP.NET Core Data Protection with Azure Key Vault for containerized app deployment. We will discuss the steps involved and provide examples to illustrate the process.

Step 1: Set up Azure Key Vault

To , we need to set up an Azure Key Vault to store our encryption keys securely. Azure Key Vault is a cloud service that allows you to safeguard cryptographic keys and secrets used by your applications.

First, log in to the Azure portal and create a new Key Vault resource. Choose a unique name for your Key Vault and select the appropriate subscription and resource group. Once the Key Vault is created, to the “Keys” section and click on “Generate/Import” to create a new key.

generating the key, make note of the key identifier and version. We will need this information in the next steps.

Step 2: Configure ASP.NET Core Data Protection

Next, we need to configure ASP.NET Core Data Protection to use Azure Key Vault as the key storage provider. Open your ASP.NET Core project and locate the “.cs” file.

In the “ConfigureServices” method, add the following code to configure Data Protection:

    .PersistKeysToAzureKeyVault(new Uri(""), "your-key-name", "your-key-version");

Replace “” with the URL of your Azure Key Vault. Also, replace “your-key-name” and “your-key-version” with the key identifier and version obtained in Step 1.

Step 3: Protecting Data

Now that we have configured ASP.NET Core Data Protection with Azure Key Vault, we can start protecting our sensitive data. Let's say we want to encrypt a connection string in our application.

In your code, use the following code to protect the connection string:

var protectedData = dataProtectionProvider.Protect("your-connection-string");

The “dataProtectionProvider” object is injected into your code injection. It provides methods for protecting and unprotecting data.

Step 4: Unprotecting Data

To retrieve the original connection string, use the following code:

var unprotectedData = dataProtectionProvider.Unprotect(protectedData);

The “unprotectedData” variable will contain the original connection string.


By using ASP.NET Core Data Protection with Azure Key Vault, we can ensure the security of sensitive data in our containerized app deployments. The integration between ASP.NET Core and Azure Key Vault provides a seamless and secure solution for data protection.

to always follow best practices for securing your Azure Key Vault and access to your encryption keys. This will help protect your application from unauthorized access and ensure the confidentiality of your data.

Implementing data protection in ASP.NET Core is crucial for safeguarding sensitive information. By leveraging the power of Azure Key Vault, we can enhance the security of our applications and protect our users' data.
