A user delegation SAS is secured with Microsoft Entra credentials and also by the permissions specified for the SAS. A new XML element will be added to the ListBlob response, named Sealed. The value can be either true or false. Calling the Append Blob Seal operation using a SAS token delegated to a container or blob resource requires the Write (w) permission as part of the service SAS token.

However to get to that stage, all of our artefacts need to be cleaned – this is where our amazing community volunteers come into the process - a big thank you to them." A shared access signature (SAS) provides secure delegated access to resources in a storage account. With a SAS, you have granular control over how a client can access data. You can specify what resource the client may access, what permissions they have to those resources, and how long the SAS is valid.

We have particularly enjoyed undertaking work to facilitate the redevelopment of Nottingham Southern Gateway, which includes Nottingham Castle. Over the course of the past year, tens of thousands of finds have been recovered, cleaned, catalogued and analysed by specialists. The Append Blob Seal operation supports three types of shared access signatures: user delegation SAS, service SAS, and account SAS.When Shared Key access is disallowed for the storage account, a service SAS token or an account SAS token will not be permitted on a request to Blob Storage.
