Hi, I’m using Apose.Slides for Java for removing passwords from Office files. This works fine for Microsoft Powerpoint files (ppt and pptx). But it fails for presentations created with OpenOffice Impress. The error that I’m getting is
com.aspose.slides.exceptions.NotSupportedException: Encryption algorithm ‘Blowfish CFB’ is not supported for decrypting the package part ‘meta.xml’.
My code looks like
InputStream is = new FileInputStream(...) LoadOptions loadOptions = new LoadOptions(); loadOptions.setPassword(pw); Presentation presentation = new Presentation(is, loadOptions);
Creating the presentation fails with above error.
I successfully processed password protected OpenOffice Calc and Writer files with Aspose.Words and Aspose.Cells. I’d be surprised, if OpenOffice would use different encryption algorithms in their products.
Is this a known limitation of Aspose.Slides?
Sample file, password is “password”
