Specifications are enough, they say…

10 years after 31c3's "Funky File Formats" …

Have things improved?

With so many open-source parsers being tested and fuzzed, and widely available specs,

what could go wrong with file formats nowadays ? Nothing to fear, right?

Let's explore even darker corners of their landscape!

Even extreme simplicity can misleadingly lead to unexpected challenges.

And at the other end of the spectrum, new complex constructs appeared over the years:

near-polyglots, timecryption, hashquines … Even AI is an element of the game now.

Let's play FileCraft, and enjoy the ride!
