Of course, we will do that.

I don't have such documents, can you attach encrypted pdf document for testing?

Thanks, which password to open it?

i don't know how it is done in acrobat. i do not need a password for it. it is a e-book which i purchased. and probably something got installed on the win pc while i was downloading the pdf

When I told about encrypted documents support, I mean password-protected encrypted documents.

Changed 2 years ago by guest

so this kind of documents will not be supported? i guess it's necessary, because more and more e-books will be around

Lucide's PDF plugin uses poppler library (http://poppler.freedesktop.org/) for pdf rendering. So we can support only features which poppler supports.

Currently, I know nothing about Acrobat's way to decrypt your PDF and which keys it uses. I tried under Windows and just got error "Document is encrypted". We will investigate, and if poppler have support for such PDFs - we will support them.
