Verifying signed commits ensures the authenticity of code contributions and maintains security in collaborative projects. As the creator of CoreUI, a widely used open-source UI library, I’ve enforced commit signing in enterprise repositories throughout my 25 years of development experience. The most straightforward method is using git log --show-signature to display GPG signature verification status for each commit. This approach provides clear indication of whether commits are properly signed and verified.

Signing Git commits with GPG keys verifies commit authenticity and proves that commits actually came from you. As the creator of CoreUI with over 25 years of development experience, I’ve implemented commit signing for security-critical enterprise projects. The most effective solution is to generate a GPG key, configure Git to use it, and enable automatic commit signing. This approach provides cryptographic proof of commit authorship with verified badges on hosting platforms.
