Signed Commit

A Git commit cryptographically signed with GPG, SSH, or S/MIME keys to verify the author's identity.

Definition

Hosting platforms show signed commits as 'Verified'. Branch protection can require signed commits, strengthening supply-chain integrity.

Example

git commit -S -m "Update ACL template"

Exam tip

Commit author fields can be spoofed; signatures prove identity.
