- Hello, PNG

can’t be the only one
Using this framework, you can started with some excercises or dig into some file formats if you want something different (many file format have segments with variable length so the header will provide either offset or length which makes a good execercise for understanding pointer arithmetic).

An MP4 file first draft
Author's github: https://github.com/corkami/pics
He works on things like hash collisions, image files that contain an image of their own hash, "polyglot" files and such like.
I think this is intended as a "minimum viable mp4 file" to show what the required binary parts are.

How to Use JSON Path
I see, thanks for replying and no worries! yeap some of the "self-describing" formats like msgpack, cbor etc will because of how fq works have to be decoded into something more of a meta-msgpack etc.
About blobs, if you want to change how (possibly large) binaries are represented as JSON you can use the bits_format options, see https://github.com/wader/fq/blob/master/doc/usage.md#options, so fq -o bits_format=md5 torepr ...
I can highly recommend to learn jq, it's what makes fq really useful, and as a bonus you will learn jq in general! :)

Reverse-engineering an encrypted IoT protocol
Hey! fq author here. I have a bunch of related tools in the readme https://github.com/wader/fq?tab=readme-ov-file#tools two suggestions: gnu poke and wireshark (can decode lots of more things then just network protocol)

To a Man with `Jq`, Everything Looks Like JSON
Did someone say let's represent structured data as json? a bit of shameless plug: https://github.com/wader/fq :) It's using a fork of gojq btw!

Jaq – A jq clone focused on correctness, speed, and simplicity
https://github.com/wader/fq has a REPL and can read JSON. Tip is to use "paste | from_json | repl" in a REPl to paste JSON into a sub-REPL, you can also use `` with fq which is a raw string literal

jq 1.7 Released
I do lots of exploratory work in various structure data, in my case often debugging media filea via https://github.com/wader/fq, which mean doing lots of use-once-queries on the command line or REPL. In those cases jq line-friendly and composable syntax and generators really shine.
