Hello,

So I've been trying to decrypt Coalesced_INT.bin from some Unreal Engine 3 game released in 2013. I've opened the .exe file in HxD and only referrence to Coalesced was this part of:

Code:

.....C.o.o.k.e.d.....%.s.=.%.s...1...Y.e.s...T.r.u.e.....O.n.....%.i.....F.a.l.s.e..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.....E.N.G.L.I.S.H.C.O.A.L.E.S.C.E.D.....%.s.C.o.a.l.e.s.c.e.d._.%.s...b.i.n....Coalesced.ini......b.i.n.....C.o.a.l.e.s.c.e.d._....'AI.'AI?'AI?'Tup'Bp'B??'B?`'B?.'B.(.-.g.A.B.C.=........?A_0mEE?G?......?A_0mEE?'Gux'F?.'Tup'Tup?..??..??..?;??.=?u?....?.6ae.C-Al@[email protected]@.A...AR..@?..??..A?..A`..B|..B?..BO..AO..A?..A ..@a..>...A?..?o......Ap..?A..A@..?tvE?....U.S.P.S.t.a.t.e.O.b.j.e.c.t.......%.s.......S.c.r.i.p.t. .c.a.l.l. .

How do I determine what part of this is key to decrypt the file (if it even is the key) and what kind of encryption was used on the .BIN file?

Always specify the name of the game(without abbreviations) and the platform.
Upload the file sample.

Lost Planet 3 for Xbox 360

Uncrypted, uncompressed .xex file - https://anonfile.com/G6F5M7r4b2/default_uncrypted_xex
Coalesced_INT.bin - https://anonfile.com/HfFcM7rebb/Coalesced_INT_bin

I would like to know the process that goes through decrypting these files, not just getting the ready key or tool.

Okay, while decompiling I've managed to find few AES S-boxes with a very convenient name of Rijndael_TeX and Rijndael_TdX (where X - number). Could that be the thing?
