How should I use the CRT manifest endpoint?

Fetch manifest JSON to pin fixture names, sizes, hashes, and MIME expectations in automated tests.

Why does this format have a category-specific hub?

A category-specific hub keeps assumptions aligned with practical workflows and related format alternatives.

CRT Format Hub

CRT (.crt) files represent certificate containers used by trust stores. Use sample CRT files to validate import logic, metadata parsing, and certificate-chain processing.

Implementation Notes

Use the manifest endpoint for deterministic fixture selection in CI, then validate MIME/type detection against actual parser output.

If this format appears in multiple categories, prefer category-specific hub pages to keep test assumptions aligned with real usage.
