The project is designed as a file resource cloner. Metadata, including digital signature, is extracted from one file and injected into another. Note: The signature is added, but not valid.

- Resource Hacker – http://www.angusj.com/resourcehacker/
- SigThief – https://github.com/secretsquirrel/SigThief (Included as a pyinstaller compiled binary)
Note: SigThief and Resource Hacker may not detect valid metadata or digital signature. This project may switch to a different tool set, but for now, be aware of potential limitations.
- Clone this project
- Download and unzip Resource Hacker to .\src\resource_hacker\ResourceHacker.exe (http://www.angusj.com/resourcehacker/resource_hacker.zip)
A version of this project has existed for several years to help a binary blend into a target environment by modifying it’s metadata. A binary’s metadata can be replaced with the metadata of a source. This includes values such as Product Name, Product Version, File Version, Copyright, etc. In addition to standard metadata, sigthief is used to add the digital signature.
