AES (Advanced Encryption Standard) is the backbone of modern digital encryption, used in everything from securing Wi-Fi networks (WPA2) to encrypting sensitive software data. However, for a computer to use AES, the decryption key must be present in the system's Random Access Memory (RAM) at the moment the data is processed.
When video game developers pack game assets—such as 3D models, textures, audio files, and dialogue—into .pak files, they secure them using 256-bit Advanced Encryption Standard (AES) keys to prevent unauthorized datamining. GHFear's tool automates the process of reverse engineering the game's static shipping executable to uncover these keys. This grants modders access to extract and modify asset files using tools like Umodel (UE Viewer) or QuickBMS . Key Technical Features of Version 1.9
While version 1.9 remains an efficient historical baseline for mid-era Unreal Engine 4 titles, GHFear eventually moved development forward. For projects built on contemporary Unreal Engine 5 branches, the developer shifted support toward upgraded versions like AES Key Finder 2.0 and the open-source tool AESDumpster. aes key finder 1.9 - by ghfear
This is perhaps the most critical section of this article. While tools like AES Key Finder 1.9 are , their use occupies a legally ambiguous space in many jurisdictions.
No tool is perfect, and AES Key Finder 1.9 has its own set of limitations that users should be aware of. AES (Advanced Encryption Standard) is the backbone of

Analyzes raw RAM dumps ( .dmp , .raw ), process memory captures, and compiled executable binaries.
Supported platforms, inputs, outputs
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.
Instead of manual memory dumping with tools like Cheat Engine or OllyDbg, users execute a streamlined command batch setup.
