Tim Allison commented on TIKA-1489:
-----------------------------------
If I understand correctly, this is a separate issue from encryption. In
PDFBox's ExtractText, there are these lines of code:
{noformat}
AccessPermission ap = document.getCurrentAccessPermission();
if( ! ap.canExtractContent() )
{
throw new IOException( "You do not have permission to
extract text" );
}
{noformat}
Again, if I understand correctly, [~tilman]'s point is that applications have a
responsibility to respect the document's desired access irrespective of
encryption.
> PDF Text extraction without permission

> Key: TIKA-1489
> URL: https://issues.apache.org/jira/browse/TIKA-1489
> Project: Tika
> Issue Type: Bug
> Affects Versions: 1.7
> Reporter: Tilman Hausherr
>
> In TIKA-1442 text extraction from files like 717226.pdf that don't have text
> extraction permission works. The permissions in PDF files are only enforced
> by the application (i.e. PDFBox), i.e. the text information isn't stored
> separately in encrypted form.
> PDFBox ExtractText command line does throw an exception.
> So I wonder why TIKA is able to extract text. Either TIKA or the PDFBox call
> used bypasses the permission checking.
