Free, no-account verification of KeyHalve-sealed documents. Read-only; never receives keys.
Scored across 3 tools
Each tool has a clearly distinct purpose: explain provides plain-language context, status gives a quick live check, and verify performs full cryptographic verification. There is no overlap or ambiguity between them.
All tools follow a consistent pattern with the 'keyhalve_' prefix and descriptive verbs (explain, status, verify). The use of 'status' as a noun is slightly atypical but doesn't break the convention.
Three tools is perfectly scoped for a verification-focused server. Each tool earns its place, covering explanation, quick status, and full verification without redundancy.
The domain is document verification, and the three tools cover the entire user journey: understanding the verdict (explain), checking current status (status), and performing a full verified check (verify). No management operations are expected for this read-only verification service.
Plain-language explanation of what a KeyHalve verification verdict means and why it can be trusted (blind rail, three-share custody, commitments, revocation). Optionally focused on one topic.
Inputs: topic.
Live status of a KeyHalve-sealed document by id: active, revoked (with reason/time), or outside its validity window. Lighter than keyhalve_verify — status only, no integrity or rail checks. Use for "is this still good right now?"
Inputs: document_id (required).
Verify a KeyHalve-sealed document. Accepts a verify URL, the raw text of a KeyHalve QR code, or a document id (vp_…, kh_…, cb_…). Returns the cryptographic verdict: whether the seal exists, its live status (active/revoked/expired), ciphertext integrity against the issuance commitment, the KeyHalve rail's independent attestation, the validity window, and the issuer's trust context. This tool NEVER decrypts sealed contents — any decryption key in the URL fragment is discarded unread; contents are only readable by opening the verify URL in a browser.
Inputs: input (required).
