You are a PyPI package maintainer tasked with securing your package releases using the new OpenID Connect identity token exchange method called 'trusted publishing'. Your goal is to configure PyPI to trust your chosen Identity Provider (IdP) and set up a secure GitHub Actions workflow to automatically exchange short-lived API tokens for publishing your package. However, you must also defend against potential attacks from hackers attempting to steal your identity and hijack your package releases. Only through quick thinking and careful management of your security settings and GitHub environment can you protect your package and maintain your reputation as a trusted publisher.
