A user delegation SAS is secured with Microsoft Entra credentials and also by the permissions specified for the SAS.

The specified blob is sealed, and its contents can't be modified unless the blob is re-created after a delete. 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 user delegation SAS token. Optional. False by default. If the blob is sealed, this header is included in the response when you seal and get properties of a blob. This header should appear in GetBlob, GetBlobProperties, AppendBlobSeal, and ListBlobs for append blobs.

This includes details of the seal's legs, body, tail, nose, eyes, whiskers, and even its spots.

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."

Over the course of the past year, tens of thousands of finds have been recovered, cleaned, catalogued and analysed by specialists. A new XML element will be added to the ListBlob response, named Sealed. The value can be either true or false. And 27 of these were based in Nottinghamshire - partly due to the number of developments currently taking place around the city.The Append Blob Seal operation supports Shared Key authorization. Authorizing with account keys is not recommended for most scenarios, as it's less secure. After you seal a blob, you can still update properties, blob index tags, and metadata. Soft-deleting a sealed blob preserves the sealed state. You can overwrite sealed blobs.
