class Aws::QLDB::Types::LedgerEncryptionDescription

Information about the encryption of data at rest in an Amazon QLDB ledger. This includes the current status, the key in Key Management Service (KMS), and when the key became inaccessible (in the case of an error).

For more information, see [Encryption at rest] in the *Amazon QLDB Developer Guide*.

@!attribute [rw] kms_key_arn

The Amazon Resource Name (ARN) of the customer managed KMS key that
the ledger uses for encryption at rest. If this parameter is
undefined, the ledger uses an Amazon Web Services owned KMS key for
encryption.
@return [String]

@!attribute [rw] encryption_status

The current state of encryption at rest for the ledger. This can be
one of the following values:

* `ENABLED`\: Encryption is fully enabled using the specified key.

* `UPDATING`\: The ledger is actively processing the specified key
  change.

  Key changes in QLDB are asynchronous. The ledger is fully
  accessible without any performance impact while the key change is
  being processed. The amount of time it takes to update a key
  varies depending on the ledger size.

* `KMS_KEY_INACCESSIBLE`\: The specified customer managed KMS key is
  not accessible, and the ledger is impaired. Either the key was
  disabled or deleted, or the grants on the key were revoked. When a
  ledger is impaired, it is not accessible and does not accept any
  read or write requests.

  An impaired ledger automatically returns to an active state after
  you restore the grants on the key, or re-enable the key that was
  disabled. However, deleting a customer managed KMS key is
  irreversible. After a key is deleted, you can no longer access the
  ledgers that are protected with that key, and the data becomes
  unrecoverable permanently.
@return [String]

@!attribute [rw] inaccessible_kms_key_date_time

The date and time, in epoch time format, when the KMS key first
became inaccessible, in the case of an error. (Epoch time format is
the number of seconds that have elapsed since 12:00:00 AM January 1,
1970 UTC.)

This parameter is undefined if the KMS key is accessible.
@return [Time]
