[Tex/LaTex] Insert pages from password protected pdf file in latex

drmpdfpdfpagesxetex

If I have a password protected PDF (my own document, source unfortunately lost), and I want to include a portion of it in a new document, can that be done?

This previous question explains how to do it in general, but when I try this with a passworded input and compile using XeLaTeX, I get a XeLaTeX error xelatex> <use "myOldPdf.pdf"> Command Line Error: Incorrect password. Is there a way to pass XeLaTeX a password for this file?

No. You have to remove the password from the PDF to be able to handle it with XeTeX/pdfTeX/LuaTeX - no program in the TeX "universe" handles password-protected PDFs.

You can not simply mix two PDF files. You have to preserve PDF document structure. In the simply case links (PDF annotations) are dropped.

You can try the PAX project, which trys to extract and reinsert the PDF annotations.

It seems that there is not such thing as native encryption (binary or text) of files from TeX. An option would be to issue a command before compilation or a shell command in order to encrypt the file before it is embedded. Doing a little further research I found that there are indeed ways to specify the password non interactively

 \documentclass[]{article}
 \usepackage{embedfile}
 \immediate\write18{zip -j -e -P mypassword -r \jobname.tex.zeep \jobname.tex}
 \embedfile{\jobname.tex.zeep}
 \begin{document}
 bla
 \end{document}

 $ zip -j -e -P mypassword -r $0.zeep $0
 $ pdflatex -shell-escape $0

zip can also be replaced by openssl des3 -salt -pass pass:mypassword -in $0 -out $0.de3;

zip is nicer because it opens from the PDF reader using just a double click on the attachments. I also use the extension zeep to avoid stupid email filters.

This is not extremely secure because the password will be visible (still not for the person receiving only the PDF), hopefully it will be a simple passphrase easy to remember at any point.

Thanks Paulo for the inspiration.
