Authentication for Azure Key Vault

Authentication​

As of today we support a few authentication mechanisms.

Managed Service Identity​

You can use Managed Service Identity to delegate the authentication to Azure via ManagedServiceIdentityAuthenticator.

var vaultAuthenticator = new ManagedServiceIdentityAuthenticator();
var vaultConfiguration = new KeyVaultConfiguration(keyVaultUri);
var keyVaultSecretProvider = new KeyVaultSecretProvider(vaultAuthenticator, vaultConfiguration);

This is the recommended approach to interact with Azure Key Vault.

Service Principle​

Authentication via username and password is supported with the ServicePrincipalAuthenticator.

var clientId = Configuration.GetValue<string>("Arcus:ServicePrincipal:ClientId");
var clientKey = Configuration.GetValue<string>("Arcus:ServicePrincipal:AccessKey");

var vaultAuthenticator = new ServicePrincipalAuthenticator(clientId, clientKey);
var vaultConfiguration = new KeyVaultConfiguration(keyVaultUri);
var keyVaultSecretProvider = new KeyVaultSecretProvider(vaultAuthenticator, vaultConfiguration);

Certificate​

Authentication via client ID and certificate is supported with the CertificateBasedAuthentication.

var clientId = Configuration.GetValue<string>("Arcus:ServicePrincipal:ClientId");
X509Certificate2 certificate = ...

var vaultAuthenticator = new CertificateBasedAuthentication(clientId, certificate);
var vaultConfiguration = new KeyVaultConfiguration(keyVaultUri);
var keyVaultSecretProvider = new KeyVaultSecretProvider(vaultAuthenticator, vaultConfiguration);
