Git - Verified Commits with SSH keys

Why Verified Commits Matter in Git — And How I Fixed Mine with SSH Signing When I first started using Git, I had no idea that anyone could easily impersonate me — or anyone else — in the commit history. It turns out it’s shockingly simple. All you need to do is run a couple of commands like: git config user.name "Someone Important" git config user.email "ceo@bigproject.com" Suddenly, your commits appear as if they came from that person. The commit message, author field, and history all reflect the fake identity. No hacking required. This isn’t just a theoretical issue. Many supply chain attacks rely on exactly this technique: an attacker creates a convincing pull request under a trusted name, gets it merged, and malicious code slips into the project.
