Unreal Engine 4 Decryption Tool

[Razor12911]

The chunked input you gave is weird too. At position *152383 the stream header begins and the is stream sized 77120 bytes and it begins from *152488‬.

The stream itself has a SHA-1 checksum of 33CD42904A9DD490861E0452CC791326FA8E85E2 but the checksum in the headers is 317F89D5663A50EB759BE2009BB937F0E3570846 therefore it was not decrypted, I wonder why is that

hmm the game is encrypted that i do know the aes_binary key is capable of decrypting for extracting wich is

_aS4mfZK8M5s5KWC2Lz2VsFnGKI7azgl

i get kernalbase.dll errors and both xtool and ue4dt crash
if i use unrealpak to extract and pack it it doesn't work right if i use bms
then pack it back up it does not work at all.. this game has me highly confused

Maybe a strange hw failure ?!

Update available

Changes

- Added block limiter (default 64 blocks), increase to catch larger streams, -b to change limit
- Added support for input with the same header structure as Rune II, -m2 for its usage

Notes

- Block limiter added speed, something I had forgotten in the other releases. You can set high values, it won't affect speed that much compared to before.

Usage

ue4dt.exe [parameters] [hexkey]

Parameters:

-c# = chunksize[k,m,g]
-b# = number of blocks
-m# = method (1 = games that use borderlands3, street figher v... format, 2 = games that use rune ii format)

Tests

On Street Fighter V:

ue4dt (0x5f6153346d665a4b384d3573354b5743324c7a325673466e474b4937617a676c):
Compressed 99 files, 43,843,420,522 => 43,843,420,522 bytes. Ratio 100.00%
Compression time: cpu 45.61 sec/real 718.01 sec = 6%. Speed 61.06 mB/s

xtool19 (precomp:deflate:c16mb,t4):
Compressed 1 file, 43,843,422,230 => 86,391,890,330 bytes. Ratio 197.05%

Hi Razor, thank you for this tool. Tested on rune and works fine. Tested on borderlands and it doesn't give big advantages. Borderlands installed with only one language 41.5GB compressed to 39GB.

I have used:

ue4dt(-m1)+XTool(v09)+srep64+4x4

The decryption key used is:

0x115EE4F8C625C792F37A503308048E79726E512F0BF8D2AD7C4C87BC5947CBA7

I don't have the previous versions of the tool, so i don't know if this last version has some problem or not.

[shazzla]

I have similar/same issues with UE4DT. (all versions !)
No matter what parameters i use ! (-m1 of course).
Examined the output after decrypting/xprecomping ,it looks like ue4dt.exe decrypts only the first few megabytes(?) of any Borderlands 3 file.

Anybody can help me ?!
What are the proper parameters of UE4DT for Borderlands 3 ?

Hi !
I Used this on Street Fighter V - Champion Edition
ue4dt + Xzlib + lolz


The compression was good (48.1gb -----24.7gb)
the problem is in the installation , it's very slow and very long!
it takes almost 7 hours to install !

please need help!thx!

Maybe its ZLib?!

[hwang4]

I Don't think "xZlib" is the problem,I did many tests!

The parameters of "ue4dt" are the problem !

when i use ue4dt with default mode (without any parameters)
the game installs without any problem(no longer slowly installation) ! but the ratio of compression is less good (48.1gb ---------->34gb)!

with these parameters:

"UE4DT.exe" e -m1 -c1024m -b1024
i got , like i told previously a good compression ratio (48.1gb ---------->24.7gb) but a very very very long & slow installation!

maybe a better configuration of parameters could solve this !

thx !

maybe try it by changing the value of -c (-c512m, -c128m, ...).
