The tool operates by scanning the compiled game’s main executable file — typically named GameName-Win64-Shipping.exe — and searching for specific patterns and signatures associated with AES key structures. When successful, it outputs the extracted key to a key.txt file, which can then be used to decrypt the game’s .pak archives.
Unlike generic memory scanning utilities that may return dozens of false positives, AES Key Finder 1.9 was tailored specifically for the way Unreal Engine implements AES encryption. The tool analyzes the game’s Shipping.exe binary, locates the embedded key, and outputs it in a format ready for use with popular extraction tools like , FModel , quickBMS , or repak .
AES Key Finder 1.9 - by GHFear represents a specialized but important tool in the intersection of software reverse engineering, game modding, and digital forensics. Its focused purpose—extracting AES-256 keys from Unreal Engine 4 executables—combined with improvements in speed, compatibility, and ease of use, has made it a valuable resource for security professionals and modders alike. aes key finder 1.9 - by ghfear
Open your terminal, navigate to the folder containing the tool, and run the executable by pointing it to your target file: aes_finder_1.9.exe -f memory_dump.dmp Use code with caution. Step 3: Interpret the Output

: The program analyzes the file structure and quickly exports the discovered strings into a file named key.txt .
The stability improvements in 1.9 are subtle but critical. Earlier iterations of similar tools often choked on false positives—flagging random high-entropy blocks as potential keys. This version, however, seems to have a much stricter validation layer. It checks the key schedule consistency. It essentially asks: "If this were a key, would the math actually work?" before presenting it to the analyst. The tool analyzes the game’s Shipping
| Feature | Description | | :--- | :--- | | | Works with Unreal Engine 4.19 through 4.27 (and potentially newer versions) | | Engine Version Detection | Automatically checks the target executable’s engine version to determine the appropriate scanning method | | Steamstub Detection | Identifies when an executable is protected by Steam’s basic DRM wrapper and notifies the user | | Significant Speed Improvement | Earlier versions could take several minutes to find a key; version 1.9 completes the task in just a few seconds | | Hex-to-Base64 Conversion | Includes a script to convert the extracted hexadecimal key into Base64 format, which is required by some decryption tools like UnrealPak | | Batch Automation | Uses a simple batch script ( RUN Find 256-bit UE4 AES Key.bat ) to automate the entire extraction process |
