# Compare output with SHA256 values listed above.Where is the machine-readable manifest?
Use the manifest when you need stable names, SHA256 values, and URLs for automation.
Use in code — curl, Python, Node, wget
Copy any snippet directly into scripts, test suites, or CI pipelines. All URLs are stable and publicly accessible with no auth required.

- Validate certificate chains, key handling, and parser behavior before any deployment use.
- Test encrypted versus unencrypted private-key handling in your loaders.
- Confirm trust-store import logic and CSR metadata inspection paths.
