title: Generate blob sasurl using SAS
body: <p>I want to get a reference to the blob and generate a SAS URL for it.</p>
  
  <p><strong>How?</strong> Without exposing my storage account key?</p>
  
  <p><strong>What all have I tried?</strong> Getting the reference to blob by using SAS (of blob container or storage account).
  My references: <a href="https://docs.microsoft.com/en-us/azure/storage/common/storage-dotnet-shared-access-signature-part-1?toc=%2fazure%2fstorage%2fblobs%2ftoc.json" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/storage/common/storage-dotnet-shared-access-signature-part-1?toc=%2fazure%2fstorage%2fblobs%2ftoc.json</a></p>
  
  <p>The exception that I see: "<strong>Can not create Shared Access Signature unless Account Key credentials are used</strong>"</p>
  
  <p>But I do not (obviously) want to expose my account key! Is this even possible? If not, is there any other way of doing it?</p>
