is a specialized, lightweight command-line utility designed to scan memory dumps and binary files to locate these hidden cryptographic keys. How AES Key Finder 1.9 Works
As developers advanced to newer game deployments, static binary parsing faced mounting technical limitations. Modern implementations utilize dynamic memory scanning rather than static file scanning to bypass anti-tamper protections. AESKeyFinder-By-GHFear - GitHub
While AES-256 itself is computationally impossible to crack via brute-force methods, the game client must still decrypt the assets on the fly during runtime to load levels and render scenes. Consequently, developers are forced to bundle the static 256-bit key inside the compiled main game executable—usually the xxxx-Shipping.exe file. Manually digging through thousands of lines of assembly or hexadecimal data using basic hex editors or decompilers to find this string can take hours or days. Utilities like the GHFear AESKeyFinder GitHub project solve this by automating the discovery process in seconds. Key Features and Capabilities of Version 1.9 aes key finder 1.9 - by ghfear
Beyond game modding, AES key recovery is a significant field in digital forensics. The fundamental principle is that cryptographic keys must be present in system memory during encryption or decryption operations. This creates opportunities for forensic investigators to locate these keys in memory captures, hibernation files, or crash dumps.
: Added script functionality to convert discovered keys from hexadecimal to base64 format.
: 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 Manually digging through thousands of lines of assembly
Though newer tools like AESDumpster have largely superseded version 1.9, its impact on the Unreal Engine modding community remains significant. Prior to its release, extracting an AES key required deep knowledge of reverse engineering, disassemblers like IDA Pro or Ghidra, and a thorough understanding of AES implementation details. AES Key Finder 1.9 changed that by wrapping a sophisticated scanning algorithm in a simple batch file that anyone could run.
It is important to note that version 1.9 is . For example, a forum member reported that the tool failed to find a key for a game using UE 4.17.2 (an older version), suggesting that version 1.9 works best with engine versions 4.19 and above . A separate tool, AESDumpster , also by GHFear, covers UE 4.0–4.16 and even extends support to UE 5.x.
This highlights a fundamental rule in cybersecurity: If a key is stored in memory on a compromised system, tools like this can find it. A separate tool
If the game is from Steam or the Epic Games Store and you encounter errors when running the finder, the executable is probably packed with SteamStub. Use Steamless:
