Unreal Engine 4 Decryption Tool

Razor12911 · #1 08-11-2019, 15:06

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.
