Encryption scopes in Azure Storage now generally available
Datum publikování: 29 března, 2021
Encryption scopes introduce the option to provision multiple encryption keys in a storage account for blobs. Previously, customers using a single storage account for multi-tenancy scenarios were limited to using a single account-scoped encryption key for all the data in the account. With encryption scopes, you now can provision multiple encryption keys and choose to apply the encryption scope either at the container level (as the default scope for blobs in that container) or at the blob level.
The key that protects an encryption scope may be either a Microsoft-managed key or a customer-managed key in Azure Key Vault. You can choose to enable automatic rotation of a customer-managed key that protects an encryption scope. When you generate a new version of the key in your Key Vault, Azure Storage will automatically update the version of the key that is protecting the encryption scope, within a day.
