Crea una nuova chiave CDN

Gli asset video vengono in genere distribuiti tramite una rete CDN (Content Delivery Network), nota anche come CDN. Per proteggere i contenuti, gli URL degli asset video possono richiedere una firma per essere recuperati; questa operazione è nota come firma dell'URL. Crea una chiave CDN per attivare l'accesso API all'asset video.
