Neuen CDN-Schlüssel erstellen

Video-Assets werden normalerweise über ein Content Delivery Network (CDN) verteilt. Um die Inhalte zu schützen, kann für den Abruf von Video-Asset-URLs eine Signatur erforderlich sein. Dies wird als URL-Signatur bezeichnet. Erstellen Sie einen CDN-Schlüssel, um den API-Zugriff auf das Video-Asset zu ermöglichen.
