Questo metodo consente di eseguire la migrazione dal precedente servizio Key Access Control List
(KACLS1) al più recente KACLS (KACLS2). È necessaria una chiave di crittografia dei dati (DEK, Data Encryption Key)
aggregato con l'API wrap di KACLS1 e restituisce un
DEK con wrapping con l'API wrap di KACLS2.
Richiesta HTTP
POST https://KACLS_URL/rewrap
Sostituisci KACLS_URL con l'elenco di controllo dell'accesso alle chiavi
URL del servizio (KACLS).
Parametri del percorso
Nessuno.
Corpo della richiesta
Il corpo della richiesta contiene dati con la seguente struttura:
Un JWT che asserisce che l'utente è autorizzato a eseguire l'unwrapping di una chiave per resource_name. Consulta i token di autorizzazione.
original_kacls_url
string
URL del KACLS dell'attuale wrapped_key.
reason
string (UTF-8)
Una stringa JSON passthrough che fornisce contesto aggiuntivo sull'operazione. Il JSON fornito deve essere sanitizzato prima di essere visualizzato. Dimensione massima: 1 kB.
In caso di esito positivo, questo metodo restituisce un oggetto binario opaco che verrà archiviato
da Google Workspace insieme all'oggetto criptato e inviato così com'è in qualsiasi
dell'operazione di unwrapping della chiave. Dovrebbe anche restituire il codice
resource_key_hash.
L'oggetto binario deve contenere l'unica copia della DEK criptata
possono essere archiviati dati specifici dell'implementazione.
Non archiviare la DEK nel tuo sistema KACLS, ma criptala e restituila
l'oggetto wrapped_key. In questo modo si evitano discrepanze tra
documento e le sue chiavi. Ad esempio, per garantire che i dati dell'utente siano completamente
o per assicurarsi che le versioni precedenti siano state ripristinate
da un backup saranno decriptabili.
Google non invierà richieste di eliminazione ai KACLS quando gli oggetti vengono eliminati.
