If any header is duplicated, the service returns status code 400 (Bad Request). The VERB portion of the string is the HTTP verb, such as GET or PUT, and must be uppercase.įor Shared Key authorization for the Blob, Queue, and File services, each header included in the signature string may appear only once. When constructing the signature string, keep in mind the following: How you construct the signature string depends on which service and version you are authorizing against and which authorization scheme you are using.

The following sections describe how to construct the Authorization header. It is possible to request a resource that resides beneath a different account, if that resource is publicly accessible. Where SharedKey or SharedKeyLite is the name of the authorization scheme, AccountName is the name of the account requesting the resource, and Signature is a Hash-based Message Authentication Code (HMAC) constructed from the request and computed by using the SHA256 algorithm, and then encoded by using Base64 encoding. The format for the Authorization header is as follows: Authorization=" :" To authorize a request, you must sign the request with the key for the account that is making the request and pass that signature as part of the request. If this header is not included, the request is anonymous and may only succeed against a container or blob that is marked for public access, or against a container, blob, queue, or table for which a shared access signature has been provided for delegated access. Specifying the Authorization headerĪn authorized request must include the Authorization header. If you set x-ms-date, construct the signature with an empty value for the Date header. The x-ms-date header is provided because some HTTP client libraries and proxies automatically set the Date header, and do not give the developer an opportunity to read its value in order to include it in the authorized request.

When this check fails, the server returns response code 403 (Forbidden). This guards against certain security attacks, including replay attacks. The storage services ensure that a request is no older than 15 minutes by the time it reaches the service. If both headers are specified on the request, the value of x-ms-date is used as the request's time of creation. You can specify the timestamp either in the x-ms-date header, or in the standard HTTP/HTTPS Date header. Specifying the Date headerĪll authorized requests must include the Coordinated Universal Time (UTC) timestamp for the request. See Delegate access with a shared access signature for more details. A container, blob, queue, or table may be available for signed access via a shared access signature a shared access signature is authorized through a different mechanism. For more information, see Manage Access to Azure Storage Resources. The following sections describe how to construct these headers.Ī container or blob may be made available for public access by setting a container's permissions. You can therefore use Shared Key Lite to make requests against the Blob and Queue services without updating your signature string.Īn authorized request requires two headers: the Date or x-ms-date header and the Authorization header. Use the Shared Key Lite authorization scheme to make requests against the Blob, Queue, Table, and File services.įor version and later of the Blob and Queue services, Shared Key Lite authorization supports using a signature string identical to what was supported against Shared Key in previous versions of the Blob and Queue services. Shared Key authorization for the Table service in version and later uses the same signature string as in previous versions of the Table service. Use the Shared Key authorization scheme to make requests against the Table service using the REST API.

Shared Key authorization in version and later supports an augmented signature string for enhanced security and requires that you update your service to authorize using this augmented signature. Use the Shared Key authorization scheme to make requests against the Blob, Queue, and File services. Shared Key for Blob, Queue, and File Services. The Blob, Queue, Table, and File services support the following Shared Key authorization schemes for version and later (for Blob, Queue, and Table service) and version and later (for File service): For more information, see Authorize with Azure Active Directory. Because Azure AD provides identity management, you can authorize access to storage resources without storing your account access keys in your applications, as you do with Shared Key.

Azure AD integration is supported for the Blob and Queue services. Azure Storage supports integration with Azure Active Directory for fine-grained control over access to storage resources.
