kavra_siegel_stamp_content | Erzeugt einen qualifizierten eIDAS-Zeitstempel für base64-encodierten Inhalt (max 1 MB). Hash wird serverseitig berechnet. RFC 3161 via SIGNIUS/IDnow. |
kavra_siegel_stamp_hash | Erzeugt einen qualifizierten eIDAS-Zeitstempel für einen SHA-256-Hash. RFC 3161 via SIGNIUS/IDnow Trust Services AB (EU Trusted List). |
kavra_siegel_verify_token | Verifiziert einen Stempel-Token anhand seiner UUID. |
