You can choose to scan the "Live Memory" (current RAM) or a "File" (such as hiberfil.sys ).
AES Key Finder 1.9 by GHFear is a specialized tool designed to extract 256-bit AES encryption keys from Unreal Engine 4 (UE4) and Unreal Engine 5 (UE5) executables. These keys are essential for decrypting and extracting game assets like models, textures, and sounds. Prerequisites : Download the utility from the official AESKeyFinder GitHub repository The Target
The modern successor to the original AES Key Finder, , offers an even simpler approach:
Rather than attempting to break the virtually uncrackable 256-bit AES algorithm mathematically, the tool intercepts how the game handles data. When an Unreal Engine game boots, it must load its default initialization keys into system memory to read the encrypted .pak files stored in its content directories. Version 1.9 leverages specialized QuickBMS logic scripts to parse the structure of the compiled target binary, sniffing out specific structural markers where the engine stores or references these static structural keys. Step-by-Step Usage Guide
The most widely documented version of the tool is , which is referenced across multiple modding wikis and forum posts.
: The tool includes a script to convert keys from hexadecimal format to Base64, which is often required for extraction tools like UModel or QuickBMS. How to Use AES Key Finder 1.9
: Locate the game’s main shipping executable (usually found in the Binaries/Win64 directory).
: Version 1.9 includes a script to convert keys from hexadecimal to base64 if needed for specific extraction tools. Troubleshooting & Tips No Key Found : If the script fails, double-check that the is actually the "Shipping" version and isn't locked by DRM. Newer Games
: For games where the key has already been found, repositories like FModel's Unreal-Game-Keys or forums like Gildor.org often host up-to-date archives.
Detects 128-bit, 192-bit, and 256-bit AES keys. Low Footprint: Lightweight tool designed for portability. How AES Key Finder Works
AES Key Finder works by analyzing either the static executable file on your hard drive or a dynamic memory dump taken while the game is running. It scans the binary data for:
In modern game modding and data reversing, extracting the Advanced Encryption Standard (AES) key is the most critical step to unlocking protected archive files. For games built on Unreal Engine, these assets are typically packed into .pak or .utoc files, which remain inaccessible without the correct 256-bit decryption string.
The tool will output the memory addresses where it detects valid key schedules, alongside the hexadecimal representation of the key:
