While AES Key Finder 1.9 remains a classic in the modding scene, it has largely been superseded by GHFear's newer project, AES Dumpster

Version 1.9 — notable changes

Do not use the standard launcher executable found in the root directory of your game installation. Instead, navigate deep into the binaries folder:

Only download the utility from verified community repositories, trusted modding forums, or GHFear’s official development channels. Avoid shady third-party file-hosting blogs.

Version 1.9 of AES Key Finder brought significant improvements, most notably full support for Unreal Engine 4.24. The release notes indicate that the tool should also support engines up to versions 4.25, 4.26, and 4.27. Previous iterations (version 1.8) supported Unreal Engine versions from 4.19 through 4.24, making 1.9 a crucial upgrade for users working with newer game titles.

While the tool has been succeeded by AESDumpster, which supports newer engine versions and adds platform compatibility, AES Key Finder 1.9 remains a stable option for working with UE4 games from versions 4.19 through 4.27. The tool's legacy includes not only its direct functionality but also the principles it demonstrates: that cryptographic keys, however securely embedded, leave detectable traces in compiled software.
