/**
 * The ``AWS::KMS::Key`` resource specifies an [KMS key](https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#kms_keys) in KMSlong. You can use this resource to create symmetric encryption KMS keys, asymmetric KMS keys for encryption or signing, and symmetric HMAC KMS keys. You can use ``AWS::KMS::Key`` to create [multi-Region primary keys](https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-overview.html#mrk-primary-key) of all supported types. To replicate a multi-Region key, use the ``AWS::KMS::ReplicaKey`` resource.
 *   If you change the value of the ``KeySpec``, ``KeyUsage``, ``Origin``, or ``MultiRegion`` properties of an existing KMS key, the update request fails, regardless of the value of the [UpdateReplacePolicy attribute](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-updatereplacepolicy.html). This prevents you from accidentally deleting a KMS key by changing any of its immutable property values.
 *    KMS replaced the term *customer master key (CMK)* with ** and *KMS key*. The concept has not changed. To prevent breaking changes, KMS is keeping some variations of this term.
 *   You can use symmetric encryption KMS keys to encrypt and decrypt small amounts of data, but they are more commonly used to generate data keys and data key pairs. You can also use a symmetric encryption KMS key to encrypt data stored in AWS services that are [integrated with](https://docs.aws.amazon.com//kms/features/#AWS_Service_Integration). For more information, see [Symmetric encryption KMS keys](https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#symmetric-cmks) in the *Developer Guide*.
 *  You can use asymmetric KMS keys to encrypt and decrypt data or sign messages and verify signatures. To create an asymmetric key, you must specify an asymmetric ``KeySpec`` value and a ``KeyUsage`` value. For details, see [Asymmetric keys in](https://docs.aws.amazon.com/kms/latest/developerguide/symmetric-asymmetric.html) in the *Developer Guide*.
 *  You can use HMAC KMS keys (which are also symmetric keys) to generate and verify hash-based message authentication codes. To create an HMAC key, you must specify an HMAC ``KeySpec`` value and a ``KeyUsage`` value of ``GENERATE_VERIFY_MAC``. For details, see [HMAC keys in](https://docs.aws.amazon.com/kms/latest/developerguide/hmac.html) in the *Developer Guide*.
 *  You can also create symmetric encryption, asymmetric, and HMAC multi-Region primary keys. To create a multi-Region primary key, set the ``MultiRegion`` property to ``true``. For information about multi-Region keys, see [Multi-Region keys in](https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-overview.html) in the *Developer Guide*.
 *  You cannot use the ``AWS::KMS::Key`` resource to specify a KMS key with [imported key material](https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html) or a KMS key in a [custom key store](https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html).
 *   *Regions*
 *  KMS CloudFormation resources are available in all Regions in which KMS and CFN are supported. You can use the ``AWS::KMS::Key`` resource to create and manage all KMS key types that are supported in a Region.

In China Regions, ``SYMMETRIC_DEFAULT`` creates a 128-bit symmetric key that uses SM4 encryption. You can't change the ``KeySpec`` value after the KMS key is created.

     *  The ``KeySpec`` property determines the type of key material in the KMS key and the algorithms that the KMS key supports. To further restrict the algorithms that can be used with the KMS key, use a condition key in its key policy or IAM policy. For more information, see [condition keys](https://docs.aws.amazon.com/kms/latest/developerguide/policy-conditions.html#conditions-kms) in the *Developer Guide*.

     *  *Multi-Region keys* are an KMS feature that lets you create multiple interoperable KMS keys in different AWS-Regions. Because these KMS keys have the same key ID, key material, and other metadata, you can use them to encrypt data in one AWS-Region and decrypt it in a different AWS-Region without making a cross-Region call or exposing the plaintext data. For more information, see [Multi-Region keys](https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-overview.html) in the *Developer Guide*.

     * Specifies the number of days in the waiting period before KMS deletes a KMS key that has been removed from a CloudFormation stack. Enter a value between 7 and 30 days. The default value is 30 days.
     *  When you remove a KMS key from a CloudFormation stack, KMS schedules the KMS key for deletion and starts the mandatory waiting period. The ``PendingWindowInDays`` property determines the length of waiting period. During the waiting period, the key state of KMS key is ``Pending Deletion`` or ``Pending Replica Deletion``, which prevents the KMS key from being used in cryptographic operations. When the waiting period expires, KMS permanently deletes the KMS key.
     *  KMS will not delete a [multi-Region primary key](https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-overview.html) that has replica keys. If you remove a multi-Region primary key from a CloudFormation stack, its key state changes to ``PendingReplicaDeletion`` so it cannot be replicated or used in cryptographic operations. This state can persist indefinitely. When the last of its replica keys is deleted, the key state of the primary key changes to ``PendingDeletion`` and the waiting period specified by ``PendingWindowInDays`` begins. When this waiting period expires, KMS deletes the primary key. For details, see [Deleting multi-Region keys](https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-delete.html) in the *Developer Guide*.
     *  You cannot use a CloudFormation template to cancel deletion of the KMS key after you remove it from the stack, regardless of the waiting period. If you specify a KMS key in your template, even one with the same name, CloudFormation creates a new KMS key. To cancel deletion of a KMS key, use the KMS console or the [CancelKeyDeletion](https://docs.aws.amazon.com/kms/latest/APIReference/API_CancelKeyDeletion.html) operation.
