Use cases

Pick the next task, not just the next file.

Use the file table first, then branch into compare or FAQ only if the task needs more context.

Compare and decide

Keep the next decision one step away.

FAQ and reference

Keep the operational details quiet.

Checksum Verification

Use checksums to confirm file integrity after download.

shasum -a 256 your_file_name_here
# 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.

Validation Methodology
  • 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.
