This report outlines the capabilities and limitations of using Microsoft's SignTool for removing digital signatures, specifically in the context of "unsigning" or "cracking" signed binaries. 1. Core Concept: "Unsigning" with SignTool

Cracking & Reverse Engineering: In "cracking" scenarios, the digital signature is often removed because any modification to the file (like patching code) breaks the original signature's integrity, making the file unusable until the signature is stripped or replaced.
