Using SignPath with GitHub Actions

This project demonstrates signing artifacts using SignPath from GitHub Actions workflows.

Signing is invoked in the sign step of .github/workflows/build-and-sign.yml.

See github.com/SignPath/github-actions for a full documentation of SignPath actions.

Policy demonstrations

This project demonstrates the following attempts to violate SignPath policies and how they are averted on the control plane:

• This step selects the appropriate signing policy depending on the branch name. The actual branch must match the branch condition of the selected signing policy. The attempt-signing-release branch demonstrates how SignPath will detect incorrect attempts.
• The release/malicious-dll branch demonstrates how SignPath will detect content-level violations of the artifact configuration.
