CancelKeyDeletion
Cancels the deletion of a KMS key. When this operation succeeds, the key state of the KMS
key is Disabled. To enable the KMS key, use EnableKey.
For more information about scheduling and canceling deletion of a KMS key, see Deleting KMS keys in the AWS Key Management Service Developer Guide.
The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of AWS KMS keys in the AWS Key Management Service Developer Guide.
Cross-account use: No. You cannot perform this operation on a KMS key in a different AWS account.
Required permissions: kms:CancelKeyDeletion (key policy)
Related operations: ScheduleKeyDeletion
Eventual consistency: The AWS KMS API follows an eventual consistency model. For more information, see AWS KMS eventual consistency.
