VerifiedGPG signing is a digital signature mechanism based on asymmetric encryption; in GitHub's release workflow, maintainers use a private key to sign release artifacts, and users can verify the signature's validity using a public key.74% similarUnverifiedCombining GPG signatures with an immutable release mechanism can, to a certain extent, defend against software supply chain attacks targeting the release stage.72% similarUnverifiedSigning published packages with GPG keys allows users to verify that the version was genuinely produced by a legitimate build process, thereby reducing the risk of dependency poisoning attacks.72% similarVerifiedGitHub's Vigilant Mode flags all commits in a repository that are unsigned or whose signatures cannot be verified, marking them as verified, unverified, or unsigned.62% similarUnverifiedFor an editor focused on local-first and privacy security, signature verification can prevent man-in-the-middle tampering with source code and forgery of publisher identity, and also lets downstream packagers and users be confident that the downloaded binaries were indeed built by the official team.62% similar
