PDF Libraries


Would we be able to use your PDF and PDF Kit libraries to do the following:

  1. Open an encrypted PDF (we know the User Password)

  2. Use PDF .Net to create a new un-encrypted PDF?

I know the Adobe Distiller respects the security of the original document and will not allow you to “print to PDF” as a way of removing the password. I would like to avoid having to go through some intermediate format (XPS, etc.) as a way of getting to a PDF with no Open password.


Thank you for considering Aspose.Pdf for .NET.

I think you can use Aspose.Pdf for .NET as per your requirement. Please see the following documentation links with details and code snippets regarding document security and encryption decryption.

Please feel free to contact support in case you face any

Thank You & Best Regards,
