2 points · Open discussionI found the info-graphics in this repository to be of great use when I was trying to digest different image formats: https://github.com/corkami/pics/blob/master/binary/PNG.png
In Hello, PNGAuthor'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.

3 points · Open discussionI wonder if there are some nice tools for "scribbling over hexdump" somewhere, and also rendering pretty output based on that. It tends to be really helpful both when synthesizing/assembling some binary formats, as well as debugging/decoding/disassembling existing ones (and then ideally also writing blogposts based on that). I saw some "annotation" tool like this in one disassembler I tried once, but it wasn't super great, and didn't allow for easy tweaking & moving of annotation groups after doing some changes in the output. I'm pretty sure this is something that's done very often by reverse-engineering people, so I'd assume tools like this should already be popular, just I don't know how to find them? I know there's also some Lua API with support for disassembling many protocols in WireShark, but I don't suppose it's easy to prototype &

quickly iterate new formats in it (?)
For some really beautiful hand-made annotated binary format hexdump, see e.g.: https://github.com/corkami/pics/blob/master/binary/DalvikEXe...
If someone knows of tools fitting more or less what I described above, I'd be super grateful for some recommendations!!
