Decrypt TFO data

[taskinoz]

The only I can seem to get out of the TFO packs from p0358 are the sounds. The rest of the files like vmts, html, js, and mdl files all seem like they are still encrypted or are garbled

Since the game is based on Titanfall 1 I can give you a sample of unencrypted and encrypted files from Titanfall Online
Titanfall Online
Ttianfall 1

Same problem with decompiling models, look like they encrypted too
Try with Crowbar 0.68
Here is sample of tf1 and tfo model

My guess is that they might be compressed, and that can cause some issues here. I suppose original CSO2 didn't have compression, but Respawn introduced compression originally in Titanfall in their customed VPK format, with lzham. Some files that are obviously already compressed are normally excluded from that.
For instance original Titanfall had uncompressed wav audio. Whereas here in TFO, UnCSO2 is able to unpack sound ogg files just fine.
So that could be the case. But it also means that TFO devs forgot to exclude some extensions from this, like webm and png. Uncompressed ones include: ogg. vtf, bik.
Edit: Looks like I was wrong, and nothing is compressed. Just that some files are stored unencrypted. But UnCSO2 shows all files in the properties as unencrypted.

A user by the name of jnkangel on Reddit showed a picture of the Destroyer Titan model in Source FilmMaker. I asked them about it too which they replied that someone has figured out decrypting TFO's model format. I didn't ask anything on the specifics but it would seem some work is happening, could be worth following up on?

sorry for bringing out the old case, but is there any progress in this ??

[taskinoz]

Yes and no, UnCSO2 can't fully decrypt TFO content but progress has been made elsewhere to dump the game assets

I apologize for commenting on a very old issue.
I've tried this with the latest copy of TFO I could find (yeah, I had to torrent it), and basically the program gets stuck parsing the files, and all the files are garbled (even the text files are garbage data)
Has any progress been made?

Here are two example text files that are garbled:
intro_captions.txt
datarevision.txt

There is a fork of libuncso2 that allows reading TFO files correctly (most of the time at least): https://github.com/p0358/libuncso2

Since the artifacts in AppVeyor expired, I can link you the compiled libuncso2.dll file that's possible to replace in the latest UnCSO2 release from this repo (2.0.7): https://titanfall.top/libuncso2.dll

Thank you! I will give it a try.

Update: Apart from one file (\platform\shaders\fxc\vertexlit_and_unlit_generic_ps50.vcs) everything seems to be unpacking correctly. This one is identified as 3.51GB file.

Everything is weird about that file tbh, I'm not sure what's going on with it, I tried looking back then but fruitlessly
