WWW-Authenticate parse

Client

Auth challenge breakdown for debugging.

WWW-Authenticate parse

Splits scheme and auth parameters from a 401 challenge header—secrets are not validated. Processing runs in your browser—Toolcore does not need your paste for the core operation on this page.

Parses pasted headers only—no outbound HTTP from this page.

How to use

Paste or type in the main field, then read the output below. Use Load example when available, or open the page with ?q= / ?qb= so tickets and agents share the same input.

  • HTTP headers — Common request and response header fields—names, direction, and short summaries—filterable client-side. Useful when the same trace needs a sibling header split.
  • HTTP fetch test — Send GET/POST and other methods from your browser—see status and body; CORS limits apply. Useful when the same trace needs a sibling header split.
  • cURL command parser — Parse curl CLI snippets into method, URL, headers, and body—local best-effort helper for API debugging. Useful when the same trace needs a sibling header split.
  • Luhn checksum (mod 10) — Paste a digit string (spaces ignored)—pass or fail Luhn for PANs, IMEI-style IDs, and test vectors; browser-only. Useful when the same trace needs a sibling header split.
