  • In the Key Vault settings, add an access policy for your application. This policy will define the permissions that your application has for accessing secrets in the Key Vault.

  • If you’re using an Azure-hosted application, you can assign an Azure Managed Identity to your application and use it to access the Key Vault. This is a secure way to authenticate your application without having to manage any credentials.

Refer to the documentation for Vault access policy.

Modify your application code to retrieve the secrets from the Key Vault

  • Use the Azure Key Vault client library to connect to the Key Vault and retrieve the secrets you need. The client library provides a simple and secure way to authenticate to the Key Vault, access secrets, and manage secret rotation and versioning.

  • Depending on the programming language and framework of your application, you can use the Azure Key Vault client library for .NET, Java, Python, or any other supported language.

Refer to the following code snippet for more details.

using Azure.Identity;
using Azure.Security.KeyVault.Secrets;

// Replace with your Key Vault URL and secret name
string vaultUrl = "";
string secretName = "my-secret";

// Authenticate to Azure using the default credentials
var credential = new DefaultAzureCredential();

// Create a new Key Vault client
var client = new SecretClient(new Uri(vaultUrl), credential);

// Retrieve the secret by name
KeyVaultSecret secret = client.GetSecret(secretName);

// Access the value of the secret
string secretValue = secret.Value;

// Use the secret value in your application

Refer to the documentation for the Azure Identity Client Library.
