Arquivos de amostra JWT
JWT (.jwt) files store JSON Web Tokens as base64url-encoded header, payload, and signature segments. Use sample JWT files to test claim validation, expiration handling, signature verification, and auth middleware behavior.

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.
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.

Validation Methodology
- Validate extension and MIME detection before processing.
- Benchmark performance with small and larger files.
- Test malformed-input handling and error messaging.
