Tools: keyhalve_verify keyhalve_status keyhalve_explain
keyhalve_verify | 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 params: input* |
keyhalve_status | 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?" params: document_id* |
keyhalve_explain | 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. params: topic |
