À utiliser ScheduleKeyDeletion avec un AWS SDK ou CLI

Pour planifier la suppression d'une KMS clé gérée par le client.

L'schedule-key-deletionexemple suivant planifie la suppression de la KMS clé gérée par le client spécifiée dans 15 jours.

Le --key-id paramètre identifie la KMS clé. Cet exemple utilise une ARN valeur clé, mais vous pouvez utiliser soit l'identifiant de la clé, soit l'identifiant ARN de la KMS clé. Le --pending-window-in-days paramètre indique la durée de la période d'attente de 7 à 30 jours. Par défaut, le délai d'attente est de 30 jours. Cet exemple indique une valeur de 15, qui indique de AWS supprimer définitivement la KMS clé 15 jours après la fin de la commande.

aws kms schedule-key-deletion \
    --key-id arn:aws:kms:us-west-2:123456789012:key/1234abcd-12ab-34cd-56ef-1234567890ab \
    --pending-window-in-days 15

La réponse inclut la cléARN, l'état de la clé, le délai d'attente (PendingWindowInDays) et la date de suppression en heure Unix. Pour afficher la date de suppression en heure locale, utilisez la AWS KMS console. KMSles clés à l'état PendingDeletion clé ne peuvent pas être utilisées dans des opérations cryptographiques.
