📜 Registrar — legal records & long-term validity
Self-maintaining long-term validity ★ Live
Qualified timestamps → PAdES-B-LTA; the renewal pass re-stamps before expiry, indefinitely.
Qualified timestamps produce PAdES-B-LTA (seal → sign → timestamp). A renewal pass detects timestamps nearing expiry and re-stamps them before they lapse, layering rather than replacing — so documents stay legally verifiable indefinitely. This self-maintaining validity is something no document vault on the market offers.
