Take potentially dangerous PDFs, office documents, or images and convert them to a safe PDF.
Literally one of the worst formats I deal with daily, from a security standpoint are PDFs. Very useful and predictable for the end user; yes, but very dangerous for the capabilities it allows.
Dangerzone works like this: You give it a document that you don’t know if you can trust (for example, an email attachment). Inside of a sandbox, Dangerzone converts the document to a PDF (if it isn’t already one), and then converts the PDF into raw pixel data: a huge list of RGB color values for each page. Then, in a separate sandbox, Dangerzone takes this pixel data and converts it back into a PDF.

A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.
This is looking like it’ll be a valuable tool I’ll use frequently.
