Per visualizzare le sovvenzioni su una chiave AWS KMS

L'list-grantsesempio seguente mostra tutte le concessioni sulla chiave KMS AWS gestita specificata per Amazon DynamoDB nel tuo account. Questa concessione consente a DynamoDB di utilizzare la chiave KMS per conto dell'utente per crittografare una tabella DynamoDB prima di scriverla su disco. Puoi utilizzare un comando come questo per visualizzare le concessioni relative alle chiavi KMS gestite e alle chiavi KMS AWS gestite dal cliente nell'account e nella regione. AWS

Questo comando utilizza il key-id parametro con un ID chiave per identificare la chiave KMS. È possibile utilizzare un ID chiave o un ARN per identificare la chiave KMS. Per ottenere l'ID chiave o l'ARN della chiave di una chiave KMS AWS gestita, usa il list-keys comando or. list-aliases

aws kms list-grants \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab

L'output mostra che la concessione autorizza Amazon DynamoDB a utilizzare la chiave KMS per operazioni crittografiche e consente di visualizzare i dettagli sulla chiave KMS () e di ritirare le sovvenzioni DescribeKey (). RetireGrant Il EncryptionContextSubset vincolo limita queste autorizzazioni alle richieste che includono le coppie di contesti di crittografia specificate. Di conseguenza, le autorizzazioni incluse nella concessione sono valide solo per l'account e la tabella DynamoDB specificati.
