View Full Version : Unreal Engine 4 Decryption Tool

Usage:
ue4dt.exe e|d -m# -c# -b# -k# <stdin> <stdout>

-m = method (1 = games that use borderlands3, street figher v... format, 2 = games that use rune ii format)
-c = chunk size
-b = block count
-k = key in hexadecimal.

The key must be in hexadecimal format. Other key formats will not work because there is currently no parser for them yet.

I am not sure if this is universal, I don't have any unreal engine games and I was sent a small sample to work on. Borderlands 3 "pakchunk2-WindowsNoEditor_0_P.pak", seems like it works

Note: This only decrypts, you'll have to find other means of precompressing the data. The input/output size remains the same.

Changes

- Replaced old SHA and AES functions for more optimized ones

Notes

- This is backwards compatible with first release, it's just faster

Thanks for the tool, works OK for BL3. Is it possible to reduce the buffer size? Now it eats >256 MB of RAM on relatively small files? Combined with main algo, srep and xtool it can easily kill all the RAM :)

Update available

Changes

- Fixed minor issues, thanks ShivShubh
- Added chunk size option as requested, its setting is optional

Notes

- This thing does not work like xtool where setting small/big chunk size has little to no difference, if an encrypted stream is truncated, it will not be decrypted
- Make sure the chunk size you use when encoding is the same as the one you set when decoding
- You may also have noticed, the key and chunk size are repeated when encoding and when decoding (the command line), that is because this tool does not store headers of its own to recall this information, which is why I did mention that the input/output size is always the same
- You can input a different key if you plan on reencrypting the data using another key, not sure why you would be doing that though but it is possible :)

Usage
ue4dt.exe e|d[chunksize] key <stdin> <stdout>

Awesome, hope we will see the same for RDR2 files :)

I'm just waiting for the key, I already have plans on how to precompress that game.

street fighter 5 is compressed
tekken 7 isn't but that game is non issue for me i have no problems with it
but when i extract SF5 and pack it back up it.. i end up having only 1 stage and ryu and ken are the only selectable fighters...
it is the only ue4 game i have problems with..
recently i decrypted soul calibur 6 no problems on it either..
i have decrypted many games but this one for some reason does not act right packed back up...

It does not act right after packing because of incorrect file paths or improper files similar to Borderlands 3. If the game can read a modified PAK file then it should have no problem at all unless you have wrong file paths or missing/corrupt files (often caused by BMS script).

indeed it was extracted by a bms script and packed pack up using unrealpack
i have done this with many games SF5 seemes temperamental with it though
i think some kind oc coding ties all the files together.. and when i extract them it messes them up

This is exactly why I use UnrealPak to extract PAK files because thats what its designed to do. BMS is a user-defined script and may go wrong anywhere possible. In one of the PAK files of Borderlands 3, QBMS and UnrealPak extract exactly same amount of files and they were almost exactly same in size (differing only in few bytes). Those few bytes were crashing the entire game.

This is just one reason, another reason is PAK files once extracted are sometimes not in their so called "Cooked" path folders so if you just pack them for use, game will not be able to read the files inside that new PAK file.

i have the unpacker too used it on tekken 7 when i first did it and my fighters were showing up invisible so i used a bms and unreal to pack it and its fine..
i also tried it on street fighter 5.. and it had alot of problems as well although other games it worked perfect on

Update available

Changes

- Fixed minor issues
- Added support for Street Fighter V type of headers

Notes

- The person who asked for Rune II support, well this has a similar format as the other games just minor differences in the header structure therefore a sample from another game which has something similar is required, better if that game also has compressed streams, not just encrypted
- Keys are in hexadecimal, they are not case-sensitive meaning letters can be upper case or lower case, it doesn't make a difference.
- I changed a few things in the source, but then this thing of changing keys for each sample has left not being sure whether the support for borderlands 3 was left unaffected, you may want to check that and compare it to last release

Here's a link where you can get keys for some games:

the 5 gb file broken into parts
[/URL]

Split the 5gb file into 256mb chunks or lower. Then process each chunks with the tool (ue4dt only) and see which chunk is failing. If multiple chunks are failing then no need to upload all of them. Just upload 1 chunk that fails and share the link here.

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

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 (0x5f6153346d665a4b384d3573354b5743324c7a325673466 e474b4937617a676c):

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:

0x115EE4F8C625C792F37A503308048E79726E512F0BF8D2AD 7C4C87BC5947CBA7

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

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!:)

shazzla

27-07-2020, 23:00

Maybe its ZLib?!

hwang4

31-07-2020, 07:32

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 !:)

Cesar82

@Razor12911
Could you create a version for us to use this way (key as a parameter)?

Arc.ini
[External compressor:ue4dt]
header = 0
packcmd = ue4dt.exe e -m2 {options} <stdin> <stdout>
unpackcmd = ue4dt.exe d -m2 {options} <stdin> <stdout>

Pack.bat
arc.exe a -ep1 -r -ed -s; -w.\temp -mue4dt:0x5DD20432F2AD810071033FC3F925FFDFD64751452 4D0A0D222E17D76BAF57BFD+lzma:ultra data.arc "pack\*"

It would be great if we had that possibility.
In this way we could send the key from a .bat file (like DiskSpan.bat currently used together with CIU).

Masquerade

08-10-2020, 23:59

@Cesar92

I had a similar idea, however {option} will still translate any given value into a command line switch.

So, ue4dt must accept this command line: ue4dt.exe e -m2 key <stdin> <stdout>

If you used {option}, a - will be appended to the key, making the run command: ue4dt.exe e -m2 -key <stdin> <stdout> leading to an error.

KaktoR

09-10-2020, 05:31

A really good idea!

This way you can copy&paste the key directly on cmd line instead of going to arc.ini and search for it :D

Cesar82

09-10-2020, 13:12

After reading the information in Razor12911 posts better.
I realized that it would also be necessary to set the parameter -m [1/2], so that through the .bat file it is possible to send the type.

It may not be possible to implement this, but it would be good.
But the normal mode could not be removed because for extraction it would be necessary to use the current mode using SetIniString for the decompression to be done using IsDone.

Maybe something that lets you use it like this:

ue4dt.exe e -m -key <stdin> <stdout>

arc.exe a -ep1 -r -ed -s; -w.\temp -mue4dt:2:0x5DD20432F2AD810071033FC3F925FFDFD647514 524D0A0D222E17D76BAF57BFD+lzma:ultra data.arc "pack\*"

-m = method (1 = games that use borderlands3, street figher v... format, 2 = games that use rune ii format)

How do we tell the difference between the 2 formats? By inspection of the game files in either sides, is m1 for pak chunks and m2 for single paks?

KaktoR

30-10-2020, 10:05

For some reason I can't use the new version with k parameter. cmd process doesn't go above 0.3% (ue4dt.exe has a cpu load at 9.9%), it just like stucks there forever.

I tested on BL3.

The old version of ue4dt works fine (with key inside arc.ini).

Same here, I tried on Xuan Yuan yesterday.

I thought this morning it was because I forgot to specify an -m switch - did you do this?

Why? Only TOC is encrypted in final version, unlike in demo.

TOC?

I checked the game exe for any encryption keys, found one (using spiritovod's tool) - so I just guessed that the main pak would be encrypted too.

TOC - table of content. Game data for XS7 is not encrypted.

@Razor12911, when you have time you could check why the previous version of ue4dt R6 works with Borderlands 3, but the new version R7 does not work.

The R7 version does not seem to work with this game.
Kaktor had to revert to ue4dt R6 version for it to work.
See the post (https://www.fileforums.com/showpost.php?p=488835&postcount=44).

The commands used in CIU were:

@Cesar

You did not include an m switch in your command?

-mk0x115EE4F8C625C792F37A503308048E79726E512F0BF8D2 AD7C4C87BC5947CBA7

Surely should be:

-mm1:k0x115EE4F8C625C792F37A503308048E79726E512F0BF 8D2AD7C4C87BC5947CBA7

Also, what is the difference between "method (1 = games that use borderlands3, street figher v... format, 2 = games that use rune ii format)"

What is difference between Borderlands 3 and Rune 2?
I forgot to include it in the post above (I corrected it in the previous post).
But in the DiskSpan command it is inserted correctly.

What is difference between Borderlands 3 and Rune 2?
I don't know, but it might be a different type of decoding, so you should use the correct -m# parameter.

No. Every minor version of UE engine have modification in pak files. This tool supports only two out of 20+

I forgot to include it in the post above (I corrected it in the previous post).
But in the DiskSpan command it is inserted correctly.

I don't know, but it might be a different type of decoding, so you should use the correct -m# parameter.

Might be Single file or Multi (PakChunk) file?

Update available

Changes

Fixed decryption bug

Notes

There was a decryption bug I didn't notice between R5-R6 which persisted in R7, sorry for inconvenience but I think it should work like R5 but with the features requested.
I noticed this bug after I remade a plugin version of this project for xtool but you can still use this.
Not forcing anyone to use the plugin, just stick with that you're used to but if you want to use the plugin version you can find it here (https://fileforums.com/showpost.php?p=489801&postcount=25).

Please use the new XTool with unreal.dll using -D3 instead because it has a slightly better ratio than UE4DT.

UE4DT slightly has some terrible results compared to new XTool by itself.

Hi Razor12911. I tested ue4dt R6 on the game SIFU. Works fine and allows a very good compression ratio after. The problem: on some configuration it gives error in installation, maybe it depends from the settings used, if you are using a large chunk size seems, maybe is that the problems, it corrupts some data and the installation gives error. I tested it on three pc with more than 1GB of chunk size and works fine in decompression but some of my downloaders are reporting error in installation. So I tried ue4dt R8 (settings ue4dt:c1024m:b256:m1) on SIFU and it must have some important bug, because it takes like forever to decrypt.. after 1h 30min it didn't finish. Tested "cls_ue4d" but the compression ratio is very bad after it. Also XTool(v0.3.9/unrealengine_R3/zlib/d1) is worst than ue4dt R6.

Provide sample and I'll take a look at the issue. If file is big, first 1GB should suffice.

yes on sifu it's not 100% full decrypted
(if i compare extracted files like .txt .json with uncrypted pak, there is some caractère missing/bad on some block, this during uncropress make crc issue)
