PDF exif meta data cleaner
==========================

[](#pdf-exif-meta-data-cleaner)

This extension will clean any PDF file uploaded to the TYPO3 system, but only with the default options. Please read the following section carefully for all details.

Important to know
-----------------

[](#important-to-know)

This extension removes all metadata information in uploaded PDF files. It requires exiftool and qpdf command line utilities to be available:

```
# ddev
ddev config --webimage-extra-packages=libimage-exiftool-perl,qpdf

# Fedora (RPM)
sudo dnf install perl-Image-ExifTool qpdf

# Debian (dpkg)
sudo apt install libimage-exiftool-perl qpdf
```

Update wizard
-------------

[](#update-wizard)

Running the update wizard processes roughly 10gb/hour, so make sure to run it via SSH/CLI.

Make a backup first:

```
mkdir -p ../fileadmin_pdf_backup/
rsync -avz --include '*.pdf' --exclude '*.*' fileadmin/ ../fileadmin_pdf_backup/
```

Then run the wizard:

```
php -d memory_limit=1G -d error_log=syslog \
    typo3/sysext/core/bin/typo3 upgrade:run 'Qbus\Pdfclean\Updates\CleanExistingPDF'
```

Also make sure to disable extensions that hook into FAL operations and clear caches in between, they will result in a massive slowdown. (Example: `fs_media_gallery`)

What this extension does
------------------------

[](#what-this-extension-does)

- Hooks into FAL API: `ResourceFactory::addFile()` and `ResourceFactory::replaceFile()`
- Hooks into FAL API: `ResourceStorage::setFileContents()`
- Hooks into DataHandler: Handling files for group/select function
- Hooks into `GeneralUtility::upload_copy_move()`
- Hooks into `GeneralUtility::upload_to_tempfile()`
- Provide an upgrade wizard for existing PDF files (please read the warnings in the upgrade wizard carefully)

WARNING
-------

[](#warning)

This extension can only sanitize the files if the upload is done in one of the ways described above. For example, if a third-party extension allows to upload files and does not use the core APIs described above, the PDF cleaner will not run.

Credits
-------

[](#credits)

Thanks to the TYPO3 GmbH and their [t3g/svg-sanitizer](https://github.com/TYPO3GmbH/svg_sanitizer) extension which provided the technical basis for this extension.
