Secure and publish Python packages: A guide to CI integration

Supply chain security in software development is crucial, and this guide outlines how to establish a secure CI/CD pipeline for Python packages using GitLab CI, focusing on package signing and attestation with Sigstore's Cosign. It explains the significance of signing and attestation for enhancing supply chain security, meeting compliance requirements, ensuring traceability, and enabling trust verification. The guide details a six-stage pipeline process that includes building, signing, verifying, publishing, and consumer verification stages, ensuring that packages remain untampered from creation to deployment. The pipeline employs Python 3.10, Cosign for cryptographic signing, and GitLab integration, while emphasizing the importance of a consistent build environment and reproducible versioning. Through this approach, organizations can provide users with secure, cryptographically verified packages, integrating modern security practices with automated processes to maintain a trustworthy software supply chain.
