![]() ![]() You can also delegate access to read, write, and delete operations on blob containers, tables, queues, and file shares that are not permitted with a service SAS.įor more information, see Create an account SAS.Ī service SAS. With the account SAS, you can delegate access to operations that apply to a service, such as Get/Set Service Properties and Get Service Stats. All of the operations available via a service SAS are also available via an account SAS. This type of SAS delegates access to resources in one or more of the storage services. Types of shared access signaturesĪzure Storage supports the following types of shared access signatures:Īn account SAS, introduced with version. The information in the SAS token is used to authorize the request. A client who has the SAS can make a request against Azure Storage by using just the SAS URI. The URI query parameters that compose the SAS token incorporate all of the information necessary to grant controlled access to a storage resource. By distributing a SAS URI to these clients, you can grant them access to a resource for a specified period of time, with a specified set of permissions. You can provide a shared access signature to clients who shouldn't be trusted with your storage account key but who need access to certain storage account resources. For information on establishing permissions, see Vaults - Create or Update and Vaults - Update Access Policy.A shared access signature (SAS) is a URI that grants restricted access rights to Azure Storage resources. purge: Purge (permanently delete) a managed storage accountįor more information, see the Storage account operations in the Key Vault REST API reference.setsas: Create or update a new SAS definition/attributes for a storage account.deletesas: Delete a SAS definition from a storage account.listsas: List storage SAS definitions for a storage account.getsas: Get information about a SAS definition for a storage account.regeneratekey: Regenerate a specified key value for a storage account.set: Create or update a storage account.restore: Restore a backed-up storage account to a Key Vault.recover: Recover a deleted storage account.list: List storage accounts managed by a Key Vault.get: Gets information about a storage account.Permissions for managed storage account and SaS-definition operations The following permissions can be used when authorizing a user or application principal to perform operations on a managed storage account: Storage account keys management in Azure Key Vault.Key Vault manages keys of both storage accounts and classic storage accounts.Key values are never returned in response to caller.Key Vault regenerates (rotates) the keys periodically.Internally, Key Vault can list (sync) keys with an Azure storage account.Key Vault can manage Azure storage account keys: You can manage keys for both storage accounts and Classic storage accounts. You can use the Key Vault managed storage account key feature to list (sync) keys with an Azure storage account, and regenerate (rotate) the keys periodically. ![]() ![]() Key Vault manages storage account keys by periodically regenerating them in storage account and provides shared access signature tokens for delegated access to resources in your storage account. The key is auto-generated and serves as a password, rather than an as a cryptographic key. Use below solution only when Azure AD authentication is not possible.Īn Azure storage account uses credentials comprising an account name and a key. Managed identities remove the need for client authentication and storing credentials in or with your application. You can use an Azure AD managed identity when you run on Azure. Azure AD integration is available for Azure blobs and queues, and provides OAuth2 token-based access to Azure Storage (just like Azure Key Vault).Īzure AD allows you to authenticate your client application by using an application or user identity, instead of storage account credentials. We recommend using Azure Storage integration with Azure Active Directory (Azure AD), Microsoft's cloud-based identity and access management service. ![]()
