What follows is a consolidated, practical walkthrough based on instructions from multiple reliable sources. The process remains largely unchanged across all versions of the tool and works for the vast majority of Unreal Engine 4 games.

is a specialized, open-source forensic tool designed to scan computer memory (RAM) or hibernation files for AES encryption keys. It is commonly used in digital forensics, incident response, and authorized security testing to recover keys used by various encryption software.

While not a household name, this tool represents a specific category of security software used to identify and extract Advanced Encryption Standard (AES) keys from running processes or memory dumps.

When software implements AES, it performs a "key expansion"—a process where the original key (128, 192, or 256 bits) is expanded into a series of round keys used for the encryption rounds.

: While version 1.9 is widely archived on sites like ResHax and GitHub , the developer has since released AESDumpster , which is considered a more modern and robust alternative for newer titles. AESKeyFinder-By-GHFear - GitHub

: This version added robust support for UE 4.24, with reported compatibility extending to 4.25, 4.26, and 4.27. Performance Optimization

: It accommodates the structural changes in how Unreal Engine 5 handles modular asset delivery and virtualized assets.

AES Key Finder 1.9 is just one component of a larger suite of tools developed by (also known as Adam) under the Illusory Software banner. Other notable projects include:

Common pitfalls and troubleshooting

Even if you close the encryption program, that key might remain in the RAM for some time. AES Key Finder scans for the specific structure of an AES key schedule—a pattern of numbers that is mathematically unique to active AES encryption. GhFear’s tool identifies: AES-256 keys

Reproducible example (minimal)

The tool needs low-level memory access, requiring Administrator privileges in Windows.

is a dedicated tool designed to extract the 256‑bit Advanced Encryption Standard (AES) key from a Windows executable that has been built with Unreal Engine 4 (or later). The utility was created by GHFear , a developer well‑known within the modding and reverse‑engineering scene for projects such as AESDumpster and the re‑tools library.

has released an updated version of AES Key Finder , a tool designed for cybersecurity professionals, reverse engineers, and malware analysts.
