I want to set up a basic private Python package index. Explain how to serve it, including strong security recommendations, and detail the technical requirements for the main and project pages according to the 'Simple repository API', specifically regarding file links.
Navigate to the 'Guides' section. Find and open the 'Hosting your own simple repository' guide. Identify the recommended methods for serving a simple repository and any strong security recommendations. Navigate to the 'PyPA specifications' section. Find and open the 'Simple repository API' specification. Locate the 'Base HTML API' section within the specification. Identify the technical requirements for the root URL (main page) and individual project URLs (project pages), including security recommendations for file links. Synthesize all gathered information to answer the question.
State that the recommended methods for serving a simple repository are using a software package (e.g., devpi) or creating a proper directory structure with a static web server. State that it is highly recommended to serve the repository with valid HTTPS. For the root URL (main page), state that it must be a valid HTML5 page with one anchor element per project, where the anchor text is the project name and the href links to the project URL. For individual project URLs (project pages), state that the URL format is /<normalized_name>/, it must be a valid HTML5 page with one anchor per file, the href is the download URL, and the anchor text is the filename. State that file links in project pages should include a hash in the form of a URL fragment like #<hash_function>=<hex_digest>.
