AES Key Finder v1.9 by GHFear is a specialized tool designed to extract 256-bit AES decryption keys from Unreal Engine 4 and 5 game executables. It is primarily used by the modding community to decrypt files and access game assets. Key Specifications & Features Engine Support : Specifically optimized for Unreal Engine versions 4.19 through 4.27 , with potential compatibility for newer versions. Version 1.9 Updates : This specific version introduced full support for and established compatibility for 4.25, 4.26, and 4.27.
: Modern versions of the tool can find a key in a few seconds, a significant improvement over earlier versions that took several minutes. Hex to Base64
: Includes a script to convert keys from hexadecimal to Base64 format, which is often required for other modding tools like How to Use Locate the game's main executable, typically named [GameName]-Shipping.exe , found in the \Binaries\Win64 Place the executable in the same folder as the AES Key Finder Run the batch script titled RUN Find 256-bit UE4 AES Key Follow any on-screen prompts and wait for the file to be generated in the folder. Important Considerations Protected Files
: The tool may not work on executables protected by DRM like . Users often need third-party tools like to unpack the before running the finder. : GHFear has since released AESDumpster
The neon hum of the server room was the only thing keeping Kael awake. It was 3:00 AM, and he was staring at a wall of encrypted static. He’d been trying to crack the "Onyx Ledger" for weeks—a ghost-chain of data that held the keys to a corporate embezzlement scheme.
Every brute-force tool he’d tried had died against the ledger’s 256-bit AES encryption. Standard kits were too slow; they were like trying to pick a lock with a wet noodle.
Kael scrolled through an old, invitation-only forum thread until he found a buried link. No flashy banner, just a plain text line: aes key finder 1.9 - by ghfear.
He’d heard of Ghfear. A ghost in the scene who wrote code that felt more like poetry than logic. Kael downloaded the file—a tiny, 40kb executable—and ran it.
The interface was deceptively simple: a black terminal window with a single pulsing green cursor. He pointed the tool at the Ledger’s memory dump. [GHFEAR_AES_1.9: INITIALIZING SCAN...]
Unlike other tools that hammered at the front door, Ghfear’s 1.9 version was surgical. It didn't guess; it listened. It looked for the "side-channel" whispers—the tiny fluctuations in CPU power and memory timing that happened when the encryption key was being used.

Kael’s heart hammered. The progress bar wasn't a bar at all, but a shifting fractal pattern that grew more complex as the search narrowed. Ghfear’s algorithm was hunting for the schedule, reconstructing the 14 rounds of the AES-256 process in reverse.
Suddenly, the screen froze. For five seconds, the server room felt silent. [KEY FOUND: 7A 4F 12 CC 8E 99 34 B1... ]
Kael copied the hex string into his decrypter. With a single click, the static vanished. Names, dates, and offshore account numbers flooded the screen in plain, damning text.
He leaned back, the green glow of the terminal reflecting in his tired eyes. Underneath the key, a final message from the tool appeared: [SUCCESS. SLEEP WELL. - GHF ] Kael closed the laptop. The ghost had delivered.
Should I add more technical details about the decryption process, or would you like a sequel where Kael uses the data he found?
The AES Key Finder 1.9 by GHFear is a specialized utility designed for the video game modding community to locate 256-bit AES encryption keys within Unreal Engine 4 (and some early UE5) executables. These keys are essential for decrypting .pak files, which house the game's core assets like textures, models, and sounds. Key Features and Capabilities
Version Support: Specifically optimized for Unreal Engine versions 4.19 through 4.27, with potential support for newer iterations.
Speed Efficiency: Version 1.8 and above significantly improved scanning speeds, reducing the wait time from minutes to just a few seconds.
Conversion Tools: Includes a script to convert found keys from hexadecimal to base64, a format often required by other extraction tools like UModel.
Engine & DRM Check: It can detect the engine version and identify if the executable is packed with Steamstub DRM, which might require additional unpacking. How to Use AES Key Finder 1.9 AES Key Finder v1
Locate the Executable: Find your game's "Shipping" .exe file. This is typically found in the game directory under \Binaries\Win64\ (e.g., xxxx-Win64-Shipping.exe).
Setup Tool Folder: Place the identified .exe into the same folder as the GHFear AES Key Finder.
Run the Script: Execute the file named "RUN Find 256-bit UE4 AES Key.bat".
Extract Key: Follow any on-screen prompts. If successful, the tool will generate several folders or a key.txt containing the possible AES keys. Evolution: AES Dumpster
While version 1.9 remains a classic for older titles, GHFear has since developed AES Dumpster, a more modern and streamlined version of the tool.
AES Dumpster offers a web-based interface and broader support for Unreal Engine 5.0 through 5.6.
It supports drag-and-drop functionality and can scan memory dumps, making it effective for games with more advanced protection.
More information on current developments can be found on GHFear's Illusory Software Patreon.
Note: This tool is intended for research purposes and personal modding only. It may require additional tools like Steamless if a game uses Steam-specific protection.
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 🧪 Typical Use Cases
: You need the game's "Shipping" executable. This is usually located in the game directory under \Binaries\Win64\ and often follows the naming pattern GameName-Win64-Shipping.exe
: If the game is protected by Steamstub, you may need a tool like
to unpack it first, as the finder cannot read encrypted executables. Step-by-Step Usage Guide Preparation
: Create a new folder and move the AES Key Finder files into it. Add Executable : Copy the xxxx-Shipping.exe
from your game's folder and paste it into the same folder as the finder tool. Run the Script : Execute the batch file named "RUN Find 256-bit UE4 AES Key" (or similar .bat file included). Follow Instructions
: A command window will open. Follow any on-screen prompts. The tool uses scripts to scan the binary for key patterns. Retrieve Key
: Once the process finishes (usually in a few seconds), the tool will display the found keys or output them to a text file.
: 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
: While version 1.9 added support for UE 4.24 through 4.27, GHFear has since released a more advanced tool called AESDumpster for more modern Unreal Engine versions. Community Resources
🧰 What is AES Key Finder?
AES Key Finder is a memory analysis and binary scanning utility that helps locate hardcoded or in-memory AES encryption keys. It's especially useful when analyzing:
- Decrypting malware configuration data
- Extracting embedded keys from unpacked executables
- Recovering keys from process dumps or full memory captures
🧪 Typical Use Cases
- Malware Analysis – Extract static AES keys used for C2 communication
- CTF Challenges – Find embedded keys in reverse engineering tasks
- Forensics – Scan memory snapshots for decryption keys
Practical Workflow
- Acquire memory image using forensic-safe methods (cold boot, live memory acquisition tools, or capture of hibernation/pagefile).
- Run AES Key Finder to scan images for candidate key material using specified key sizes.
- Validate candidates by attempting decryption on sample ciphertext or checking derived round keys for correctness.
- Correlate recovered keys with running processes or application artifacts to identify origin and scope of exposure.
- Report findings with remediation recommendations.
