Hi Aspose team, when I saved the attached PPT sample (have password), the results returned were different:

  • Aspose Slides 21.2: throw InvalidPasswordException
  • Aspose Slides 23.12: save successfully

Please explain to me the reason for that problem. Thank you.
Here is the code, I using .NET5:

try
{
    using(var inputStream = new FileStream(inputFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
    {
        presentation = new Presentation(inputStream);
        presentation.Save(outputFile, SaveFormat.Ppt);
    }
}
catch(InvalidPasswordException)
{
    retVal = 1;
}

Hi @andrey.potapov, I would consider this an improvement so no description of expected results. Can you explain to me why there are that differences and which Aspose Slides version it was changed from?

@dunghnguyen,
Our developers have investigated the case. The Aspose.Slides behavior you encountered is correct under the given conditions. The behavior has changed since version 23.12 as a result of improvements. Previously this did not work correctly.
