Get page count from encrypted document
Hi,
I have a number of PDF's with various levels of security and need to be able to get a page count from them.
The getNumberOfPages call fails to return a value with a document that is secured, while Adobe reader and windows preview are able to get the page count.
[cid:image001.jpg@01CF8C8D.050EFF20]
PDDocument doc = PDDocument.load(new File(args[0]));
int count = doc.getNumberOfPages();
Does anyone have any thoughts as to why and how I can get a page count?
Regards
John

I would suggest you open up the PDF in a text editor and see if you can a
page object with it's count. On all of my examples those objects are
encrypted with the key so there is no way for pdf box to figure out how
many pages there are

I agree in principle, but there could be some technical issues that prevent
it, as an encryption policy is basically a type of digital signature that
is applied to the file.

RE: Get page count from encrypted document
Posted by John Milne <JM...@phlexglobal.com>.
Hi,
Agreed, but there are different levels of security available on a PDF.
Simple security such as preventing changing a document, commenting it, or form field fill in should not prevent a page count being returned without calling the openProtection() method first.
If you can view the document, then the page count should be available. To my mind anyhow.
Regards
John

The entire point of encryption is to prevent someone without the right knowledge (the password) from gaining access to the contents of your file, such as the number of pages in it.

One last question for someone.
Why do we need to decrypt the PDF to simply get the page count?
Thanks

After you load the document
if(document.isEncrypted())
{
document.openProtection(new StandardDecryptionMaterial(""));
}
In the "" enter the password if required.
