x-fb-zd dict dump

Open novitae opened this issue 1 year ago • 2 comments

Hey, I am trying to find out how did you dumped the dictionary you are talking about here: https://github.com/mame82/misc/blob/157c17cb0cd7fb2406522d49a6b0a517d4fce1a3/fb-zstd.py#L23-L23

I would like to do it myself, because it seems that they added a new version, and that you can now specify which one do you want. I think that even if it is hardcoded, the dictionary doesn't change, but id like to get it. Capture d’écran 2024-01-15 à 14 25 41 Capture d’écran 2024-01-15 à 14 26 14

T.b.h. even if I could remember what I did 3 years back, I would not give such a clear advise. Suggesting (how I would approach it, if I have to redo it): Grab the (old) APK I used, extract the library. Search for the dict from my script (bytematching), reverse respective code (referencing the dict) ... apply gained knowledge to newer implementations as starting point for reversing.
