Decrypting pdf files

[Mateusz Rogulski]

Hi,

Is there a way to decrypt PDF file using syncfusion File Formats? On your site there is info as endcypring/decrypting is one of the main features, but I haven't found such possibility. Each demo shows only encryption and after looking info PDFSecurity class I've also haven't found anything related to decrypting. Is there a way to do this?

Best regards,

Mateusz

Hi Mateusz, 

Thank you for using Syncfusion product, 

We can achieve Decrypting PDF file using PdfLoadedDocument. We have attached code snippet and sample for your reference. 

   

 PdfLoadedDocument ldoc = new PdfLoadedDocument(“Encrypt.pdf”, "syncfusion");   

 PdfDocument doc = new PdfDocument(); 

 doc.ImportPageRange(ldoc, 0, ldoc.Pages.Count - 1);

Hi Sasi,

thanks a lot! It solved my problem in 100%. My only suggestion is to somehow improve documentation because I've found it very hard to find anything about that.
