Cediddi opened a new issue, #1805:
URL: https://github.com/apache/libcloud/issues/1805

   ## Summary
   
   I've been trying to generate a signed download link to a file with spaces in its name, let's call it `file name.txt`, and it has been failing to generate a token. While, If I use Azure's frontend, I can generate a token that works. I suspect the signature is calculated incorrectly.
   
   ## Detailed Information
   
   I had theorized that, azure don't `urlencode` the resource because it would be pointless if you are going to hash it. I've checked the official implementation and indeed they don't and use raw resource name when creating the signature. After that, I've created a subclass of `AzureBlobsStorageDriver` with `get_object_cdn_url` overloaded, and I've edited the `string_to_sign`'s content with this:
   
   ```diff
   + "/blob/{}{}".format(self.key, unquote(object_path)),
   - "/blob/{}{}".format(self.key, object_path),
   ```
   
   And indeed it works now for any file I tried.
   
   My Environment:
   python==3.10.5
   libcloud==3.6.0
   operating system is official python:3.10 from docker
