Decrypt PDF for saving

Hi,

How would i go about saving a decrypted file as a pdf instead of just opening it...ie...In the following code below.

public void loadPdfDocument(DownloadFile downloadFile) {
if (isAdded()) {
try {
String path = downloadFile.getFilePath() + "/" + downloadFile.getFileName();
this._pdfLoadingIndicator.setVisibility(;
this._doc.Close();
int ret = this._doc.OpenStream(new PDFMemStream(PDFUtil.decryptPDF(BuildConfig.PDFPassword, path)), null);
System.gc();
if (ret == 0) {
this._reader.setVisibility(0);
this._reader.PDFOpen(this._doc, this, PDFDetailsActivity.DISPLAY_METRICS);
//I want to save a copy of the PDF into the downloads directory!
String home = System.getProperty("user.home");
this._reader.PDFSave(this._doc????
}
} catch (Exception e) {
e.printStackTrace();
}
}
}

Hi,
I suggest you to use
Make sure to save the pdf to a new correct path.

Alright thanks, that worked fine. Another question I have would be that I intend to have the optoin of having a similar desktop app for my clients. Would you be able to explain how to encryption protocol is or if you have a snipped for V.B.NET to decrypt the PDF file that's encrypted? (Once i provide the password)

Thanks!

It's not clear the algorithm you are adopting in PDFUtil.decryptPDF, but generally we support the standard encryption/decryption algorithms like AES for example. You can check Document.EncryptAs, or you can implement your own algorithm by extending PDFStream (check PDFAESStream in the demo project).

No, Currently we do not support .NET desktop applications, we support UWP.

If you are interested in desktop apps, you can open a ticket in the support tickets area and address it to RadaeePDF Sales

Does the uwp sdk support the aes decryption? Because I took a quick look at the documentation and was unable to find the supporting function.
Also is the uwp sdk free ir paid?

Thanks
