# TruePolyglot #
Truepolyglot is polyglot file generator project. It means the generated file is composed of several file formats. The same file can be opened as a ZIP file and as a PDF file for example. The idea of this project comes from the work of [Ange Albertini](https://github.com/corkami), [International Journal of Proof-of-Concept or Get The Fuck Out](https://www.alchemistowl.org/pocorgtfo/pocorgtfo07.pdf) and [Julia Wolf](https://www.troopers.de/wp-content/uploads/2011/04/TR11_Wolf_OMG_PDF.pdf) that explain how we can build a polyglot file.\
Polyglot file can be boring to build, even more if you want to respect the file format correctly.\
That's why I decided to build a tool to generate them.\
My main motivation was the technical challenge.
## Features and versions ##
| Description | Version |
| ----------- | ------- |
| Build a polyglot file valid as PDF and ZIP format and that can be opened with 7Zip and Windows Explorer | POC |
| Add a stream object in the PDF part | POC |
| Polyglot file checked without warning with [pdftocairo](https://poppler.freedesktop.org/) | >= 1.0 |
| Polyglot file checked without warning with [caradoc](https://github.com/ANSSI-FR/caradoc) | >= 1.0 |
| Rebuild the PDF Xref Table | >= 1.0 |
| Stream object with the correct length header value | >= 1.0 |
| Add the format "zippdf", file without offset after the Zip data | >= 1.1 |
| Polyglot file keeps the original PDF version | >= 1.1.1 |
| Add the "szippdf" format without offset before and after the Zip data | >= 1.2 |
| Fix /Length stream object value and the PDF offset for the szippdf format | >= 1.2.1 |
| PDF object numbers reorder after insertion | >= 1.3 |
| Add the format "pdfany" a valid PDF with custom payload content in the first and the last objet | >= 1.5.2 |
| Add "acrobat-compatibility" option to allow szippdf to be read with Acrobat Reader (thanks Ange Albertini)| >= 1.5.3 |
| Add the format "zipany" a valid ZIP with custom payload content at the start and between LHF and CD | >= 1.6 |
## Polyglot file compatibility ##
| Software | Formats | status |
| -------- | ------- | ------ |
| Acrobat Reader | pdfzip, zippdf, szippdf, pdfany | OK |
| Sumatra PDF | pdfzip, zippdf, szippdf, pdfany | OK |

| Firefox | pdfzip, zippdf, szippdf, pdfany | OK |
| 7zip | pdfzip, zippdf, zipany | OK with warning |
| 7zip | szippdf | OK |
| Explorer Windows | pdfzip, zippdf, szippdf, pdfany, zipany | OK |
| Info-ZIP (unzip) | pdfzip, zippdf, szippdf, pdfany, zipany | OK |
| Evince | pdfzip, zippdf, szippdf, pdfany | OK |
| pdftocairo -pdf | pdfzip, zippdf, szippdf, pdfany | OK |
| caradoc stats | pdfzip, pdfany | OK |
| java -jar | szippdf | OK |
