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 CertifidateBasedAuthentication.

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);
