The project is designed as a file resource cloner. Metadata, including digital signature, is extracted from one file and injected into another.
Note: Signatures are copied, but no longer valid.
This project is based on a technique I've used for a few years. This has been updated and modified to include copying digital signatures.
Thanks @subtee for the tweet that encouraged this project to be updated and published !!

## Description
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 now used to copy a digital signature.
## Usage
SYNOPSIS MetaTwin copies metadata and AuthentiCode signature from one file and injects into another.
