Just try clicking enter when it asks for key.
From what I know, TEKKEN 7 has no encryption.

Hi guys!
Can anybody help with the encryption key for the UE4 pack files of the western version of Lineage 2 Revolution (mobile game)?
I can provide any files you need for this.

@Icos
Have you tried just pressing RETURN without entering any key?
Last time I checked that game didn't use encryption, just a "fake" encryption-enabled field.

[Icos]

Yeah i did. Actually SEA version of the game still has no encryption at all, but western one now has it.
Gildor's umodel also says that the extracted files are encrypted.

Uploaded the apk, lib and one of the pak files: link.

Try this: 0xD7FEDB52DF0DFD7388CF5CB0EAEA7731B5D1E24EA6A8A8791E220AF82C3452C1

Will post more keys as I find them.
If a key works, post which one in a reply without Quoting this message.
Also put the name of the game in the reply so people know what game the key is for.

Game: Darwin Project

Key: 0xD7FEDB52DF0DFD7388CF5CB0EAEA7731B5D1E24EA6A8A8791E220AF82C3452C1

(thank you very much, GHFear. It works )

Hi, I found these files ( names in attachment ) extracted from tk7ue do not have normal .uasset header magic C1832A9E,
instead they are 09F848C6FA0BB4B180A8E832ED9C3D62.

I run the game with extracted assets (paks removed), but can not enter into any 3d scene,
I think those files cause the problem (so those are not unused files).

Wish your advice if you have experience of such kind of files.

There's also a suspicious string in TekkenGame-Win64-Shipping.exe:14286EB20

Tekken 7 has it's own in-house encryption on some files, like animations.
and nobody has figured it out yet. "i think".

Judge by the name and file size they are mostly textures.

I did a track in ram, tweak <rcx in 145C36494> = <&vtabl_14284B250+0x40> to 1,
those files do got decoded back to C1832A9E one, the routine is unknown ( it has denuvo, ida won't help )

Anyway tk7 DOES have encrypted chunks in paks, but not represents themselves in FPakEntry.bEncrypted.

Also anyone who has interest, may see into func_145DB74A0, not sure is that the generic ue4 aes function.

Okay hole trap found, it compare path with a list of strings at 2860D40 (142861B40),
if the path matches one of the patterns,
it generate a 0xf0 key block at func_1407A8F20 ( denuvo re-addr: func_145DB74A0),
then process first 0x1000 of the data with func_1407A7DB0, 0x10 per loop.

But the encrypted block of some .uasset is obviously less then 0x1000...
Say Logo_SquareEnix.uasset, it should be 0x490.
