Výsledek analýzy HTTPS na portal.nukib.gov.cz ze dne 19.06.2026

Služba je chráněna certifikátem od certifikační autority, kterou hlavní prohlížeče neznají nebo jí nedůvěřují. V českých podmínkách to znamená nejspíše certifikáty vydané našimi vnitrostátními autoritami (ICA, PostSignum a eIdentity), které sice stát zákonem prohlásil za důvěryhodné, ale které nesplňují mezinárodní podmínky nutné proto, aby je za důvěryhodné pokládali i autoři prohlížečů.
