restore_key¶

PaymentCryptographyControlPlane.Client.restore_key(**kwargs)¶

Cancels a scheduled key deletion during the waiting period. Use this operation to restore a Key that is scheduled for deletion.

During the waiting period, the KeyState is DELETE_PENDING and deletePendingTimestamp contains the date and time after which the Key will be deleted. After Key is restored, the KeyState is CREATE_COMPLETE, and the value for deletePendingTimestamp is removed.

Cross-account use: This operation can’t be used across different Amazon Web Services accounts.

  - UsingDefaultReplicationRegions (boolean) –
    
    Indicates whether this key is using the account’s default replication regions configuration.
    
    When set to true, the key automatically replicates to the regions specified in the account’s default replication settings. When set to false, the key has a custom replication configuration that overrides the account defaults.
