Unreal Engine 4 Decryption Tool

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

Update available

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

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

Use this:
Code:
0x5f6153346d665a4b384d3573354b5743324c7a325673466e474b4937617a676c
If it doesn't works then use in all caps.
