+% and the |pdftrailerid| which allows you to create reproducible pdfs. +% +% \section{Requirements} +% +% |Pdfprivacy| requires a recent version of pdf\TeX{} (version $1.40.17$ or above\footnote{\url{https://www.tug.org/texlive/Contents/live/texmf-dist/doc/pdftex/NEWS}}) if you want to suppress the inclusion of the pdf\TeX{} banner. +% \begin{quotation} +% \texttt{PTEX.Fullbanner This is pdfTeX, Version 3.14159265...} +% \end{quotation} +% +% \section{Usage} +% +% To use |pdfprivacy|, simple include it: +% +%\begin{quote} +% |\usepackage|\oarg{options}|{pdfprivacy}|, +%\end{quote} +% +% Options are passed on to |pdfprivacy| as key-value pairs. +% By default, the options are set as follows: +% +%\begin{quote} +% |nodocdata=false,|\\ +% |noeditdata=true,|\\ +% |noproducerdata=true,|\\ +% |noptexdata=true,|\\ +% |nopdftrailerid=false| +%\end{quote} +% +% This removes/suppresses all pdf creator, producer, dates, and pdfTeX meta-data. +% Standard document properties such as title, author, subject, and keywords are still kept. +% The |pdftrailerid| is kept as well by default. +% +% \subsection{Options} +% All |pdfprivacy| options are boolean. +% Each option is prefixed with |no| to indicate you want the meta-data removed, you can specify the opposite as well (e.g., both |nodocdata=true| or |docdata=false| are valid options). +% \begin{description} +% \item[nodocdata=\meta{boolean}] Specify whether document meta-data should be removed from the pdf. Document meta-data includes: +% \begin{enumerate*}[label=(\roman*)] +% \item Title, +% \item Subject, +% \item Author, and +% \item Keywords +% \end{enumerate*}. +% \item[noproducerdata=\meta{boolean}] Specify whether meta-data on the pdf-producing application should be removed. This includes: +% \begin{enumerate*}[label=(\roman*)] +% \item Creator, and +% \item Producer +% \end{enumerate*}. +% \item[noeditdata=\meta{boolean}] Specify whether meta-data on the edit and creation dates should be removed. This includes: +% \begin{enumerate*}[label=(\roman*)] +% \item creation date, and +% \item modification date +% \end{enumerate*}. +% \item[noptexdata=\meta{boolean}] Specify whether the PTEX meta-data entries should be suppressed. This includes: +% \begin{enumerate*}[label=(\roman*)] +% \item PTEX.Fullbanner, +% \item PTEX.FileName, +% \item PTEX.PageNumber, and +% \item PTEX.InfoDict +% \end{enumerate*}. +% \item[nopdftrailerid=\meta{boolean}] Specify whether the pdfrailerid should be omitted. +% \end{description} +% +% \subsection{Using pdfprivacy without hyperref} +% +% When using |pdfprivacy| without |hyperref|, the |\pdfinfo| command is used to set the pdf meta-data properties (i.e., |Title|, |Subject|, |Keywords|, |Author|, |Creator|, and |Producer|). +% The |\pdfinfo| works by appending the provided properties to the pdf info dictionary. +% This means that any previously set properties will still be present in the resulting pdf, despite pdf viewers only showing the last one. +% To make sure these properties are not present, \emph{do not} manually set any of these properties, or use |hyperref| to set them. +% |Hyperref| will only save the last property (i.e., the empty one set by |pdfprivacy|) to the pdf. +% To make absolutely sure that no meta-data is present in the resulting pdf, you can always manually check the pdf by opening it as a text file.\footnote{Note: privacy-sensitive content may be present in the pdf in an encoded form. When manually verifying, make sure to look for the pdf property (e.g., |/Author (|\meta{content}|)| as well to verify it is empty.} +% +% \subsection{Removing the pdftrailerid} +% +% The pdf trailer ID is a generated ID to uniquely identify a pdf. +% The generated ID is based on the time of creation. +% This ID can be removed to make reproducible pdfs, i.e., with the same cryptographic hash. +% +% \textbf{Important:} The pdf trailer id is kept by default because it is optional but strongly recommended by the pdf standard.\footnote{\url{https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_reference_1-7.pdf\#G8.1639448}} +% Not including this entry could break some workflows that rely on the trailer ID to uniquely identify files. +% If this is not a concern, the |nopdftrailerid=true| option can be used to remove it as well. +% +% \StopEventually{% +%\clearpage% +%\PrintIndex% +%\clearpage% +%\PrintChanges} +% +% \clearpage +% \section{Implementation} +% +% \subsection{Loading packages} +% +% Load |ifthen| for ifthenelse and booleans for managing user preferences. +% \begin{macrocode} +\RequirePackage{ifthen} +% \end{macrocode} +% Load |kvoptions| for laoding key-value options. +% \begin{macrocode} +\RequirePackage{kvoptions} +% \end{macrocode} +% +% \subsection{Storage for options and settings} +% Some booleans for keeping track if hyperref is loaded and if all meta-data should be removed. +% \begin{macrocode} +\newboolean{pdfprivacy@hyperrefloaded} +\newboolean{pdfprivacy@removeall} +\setboolean{pdfprivacy@removeall}{false} +% \end{macrocode} +% +% \subsection{Declaring package options} +% Declare all the package options and their complementary ones. +% \begin{macrocode} +\DeclareBoolOption[false]{nodocdata} +\DeclareComplementaryOption{docdata}{nodocdata} +\DeclareBoolOption[true]{noproducerdata} +\DeclareComplementaryOption{producerdata}{noproducerdata} +\DeclareBoolOption[true]{noeditdata} +\DeclareComplementaryOption{editdata}{noeditdata} +\DeclareBoolOption[true]{noptexdata} +\DeclareComplementaryOption{ptexdata}{noptexdata} +\DeclareBoolOption[false]{nopdftrailerid} +\DeclareComplementaryOption{pdftrailerid}{nopdftrailerid} +% \end{macrocode} +% Additional |all| option to just remove everything. +% \begin{macrocode} +\DeclareVoidOption{all}{\setboolean{pdfprivacy@removeall}{true}} +% \end{macrocode} +% +% Process the options. +% \begin{macrocode} +\ProcessKeyvalOptions* +% \end{macrocode} +% +% \subsection{Process the user preferences} +% +% Check if we need to remove |all| and override the other preferences. +% \begin{macrocode} +\ifthenelse{\boolean{pdfprivacy@removeall}}{% +\setboolean{pdfprivacy@nodocdata}{true} +\setboolean{pdfprivacy@noproducerdata}{true} +\setboolean{pdfprivacy@noeditdata}{true} +\setboolean{pdfprivacy@noptexdata}{true} +\setboolean{pdfprivacy@nopdftrailerid}{true} +}{% +} +% \end{macrocode} +% +% Check if hyperref is loaded as some meta-data needs to be set using hyperref. +% \begin{macrocode} +\AtBeginDocument{ +\@ifpackageloaded{hyperref}{\setboolean{pdfprivacy@hyperrefloaded}{true}}{\setboolean{pdfprivacy@hyperrefloaded}{false}} +} +% \end{macrocode} +% +% +% \subsection{Remove or suppress all the necessary meta-data} +% +% Process docdata preference. +% \begin{macrocode} +\AtBeginDocument{ +\ifthenelse{\boolean{pdfprivacy@nodocdata}}{% + \ifthenelse{\boolean{pdfprivacy@hyperrefloaded}}{% + \hypersetup{pdfinfo={ Author={}, Subject={}, Title={}, Keywords={} }}% + }{% + \pdfinfo{/Author () /Title () /Subject () /Keywords () }% + } +}{% +} +} +% \end{macrocode} +% +% Process producerdata preference. +% \begin{macrocode} +\AtBeginDocument{ +\ifthenelse{\boolean{pdfprivacy@noproducerdata}}{% + \ifthenelse{\boolean{pdfprivacy@hyperrefloaded}}{% + \hypersetup{pdfinfo={ Creator={}, Producer={} }}% + }{% + \pdfinfo{/Creator () /Producer ()}% + } +}{% +} +} +% \end{macrocode} +% +% +% Process editdata preference. +% \begin{macrocode} +\ifthenelse{\boolean{pdfprivacy@noeditdata}}{% +\pdfinfoomitdate1 +}{} +% \end{macrocode} +% + +% \begin{macrocode} +% \end{macrocode} +% +% Process the PTEX data preference. +% \begin{macrocode} +\ifthenelse{\boolean{pdfprivacy@noptexdata}}{ +\pdfsuppressptexinfo-1 +}{} + +% \end{macrocode} +% +% Process the pdftrailerid preference. +% \begin{macrocode} +\ifthenelse{\boolean{pdfprivacy@nopdftrailerid}}{ +\pdftrailerid{} +}{} + +% \end{macrocode} +% +% +% +% \Finale +\endinput
