The application also gracefully handles rotating Secrets, retiring . The ASP.NET Core Data Protection API in action. The app generates a data protection key when it is needed. This folder is backed by network storage and is synchronized across all machines hosting the app. By using an Azure Resource Group project, the secret app settings can be fetched from the Azure Key Vault during deployment, and deployed to the Azure App Service. How to get started 1. If you specify an explicit key persistence location, the data protection system deregisters the default key encryption at rest mechanism.Consequently, keys are no longer encrypted at rest. This key ring contains both expired keys and the current key. A vault is logical group of secrets. services. I think this is somewhat critical given that so much is moving to Azure right now. This may be data your program explicitly stores by calling DPAPI methods like Protectand Unprotect, but it also applies to certain pieces of data ASP.NET Core stores automatically, including login data. Keys can be shared across several instances of a web app. az keyvault create --name "MyKeyVault" --resource-group "MyRG" --location "East US". Azure Files might cut it for a network share (?) That way, items that are encrypted by any instance can be decrypted by any other instance. In the menu of available services, choose Azure Key Vault and click Next. Click "Generate/Import" button to create new secret pair. We can grant access policies of this Key Vault to app registration, which we have created already. Click "+ Add Access Policy".
