+    # Creates a [custom key store][1] backed by a key store that you own and
+    # manage. When you use a KMS key in a custom key store for a
+    # cryptographic operation, the cryptographic operation is actually
+    # performed in your key store using your keys. KMS supports [CloudHSM
+    # key stores][2] backed by an [CloudHSM cluster][3] and [external key
+    # stores][4] backed by an external key store proxy and external key
+    # manager outside of Amazon Web Services.
+    #
+    # This operation is part of the [custom key stores][1] feature in KMS,
+    # which combines the convenience and extensive integration of KMS with
+    # the isolation and control of a key store that you own and manage.
+    #
+    # Before you create the custom key store, the required elements must be
+    # in place and operational. We recommend that you use the test tools
+    # that KMS provides to verify the configuration your external key store
+    # proxy. For details about the required elements and verification tests,
+    # see [Assemble the prerequisites (for CloudHSM key stores)][5] or
+    # [Assemble the prerequisites (for external key stores)][6] in the *Key
+    # Management Service Developer Guide*.
     #
-    # This operation is part of the [Custom Key Store feature][1] feature in
-    # AWS KMS, which combines the convenience and extensive integration of
-    # AWS KMS with the isolation and control of a single-tenant key store.
+    # To create a custom key store, use the following parameters.
     #
-    # Before you create the custom key store, you must assemble the required
-    # elements, including an AWS CloudHSM cluster that fulfills the
-    # requirements for a custom key store. For details about the required
-    # elements, see [Assemble the Prerequisites][3] in the *AWS Key
-    # Management Service Developer Guide*.
+    # * To create an CloudHSM key store, specify the `CustomKeyStoreName`,
+    #   `CloudHsmClusterId`, `KeyStorePassword`, and
+    #   `TrustAnchorCertificate`. The `CustomKeyStoreType` parameter is
+    #   optional for CloudHSM key stores. If you include it, set it to the
+    #   default value, `AWS_CLOUDHSM`. For help with failures, see
+    #   [Troubleshooting an CloudHSM key store][7] in the *Key Management
+    #   Service Developer Guide*.
+    #
+    # * To create an external key store, specify the `CustomKeyStoreName`
+    #   and a `CustomKeyStoreType` of `EXTERNAL_KEY_STORE`. Also, specify
+    #   values for `XksProxyConnectivity`,
+    #   `XksProxyAuthenticationCredential`, `XksProxyUriEndpoint`, and
+    #   `XksProxyUriPath`. If your `XksProxyConnectivity` value is
+    #   `VPC_ENDPOINT_SERVICE`, specify the `XksProxyVpcEndpointServiceName`
+    #   parameter. For help with failures, see [Troubleshooting an external
+    #   key store][8] in the *Key Management Service Developer Guide*.
+    #
+    # <note markdown="1"> For external key stores:
+    #
+    #  Some external key managers provide a simpler method for creating an
+    # external key store. For details, see your external key manager
+    # documentation.
+    #
+    #  When creating an external key store in the KMS console, you can upload
+    # a JSON-based proxy configuration file with the desired values. You
+    # cannot use a proxy configuration with the `CreateCustomKeyStore`
+    # operation. However, you can use the values in the file to help you
+    # determine the correct values for the `CreateCustomKeyStore`
+    # parameters.
+    #
+    #  </note>
     #
     # When the operation completes successfully, it returns the ID of the
     # new custom key store. Before you can use your new custom key store,
-    # you need to use the ConnectCustomKeyStore operation to connect the new
-    # key store to its AWS CloudHSM cluster. Even if you are not going to
-    # use your custom key store immediately, you might want to connect it to
-    # verify that all settings are correct and then disconnect it until you
-    # are ready to use it.

+    #   credentials.
+    #
+    #   This parameter doesn't set or change the authentication credentials
+    #   on the XKS proxy. It just tells KMS the credential that you
+    #   established on your external key store proxy. If you rotate your proxy

+    #   `CustomKeyStoreType` of `EXTERNAL_KEY_STORE`.
+    #
+    #   If the external key store proxy uses a public endpoint, specify
+    #   `PUBLIC_ENDPOINT`. If the external key store proxy uses a Amazon VPC
+    #   endpoint service for communication with KMS, specify
+    #   `VPC_ENDPOINT_SERVICE`. For help making this choice, see [Choosing a
+    #   connectivity option][1] in the *Key Management Service Developer
+    #   Guide*.
+    #
+    #   An Amazon VPC endpoint service keeps your communication with KMS in a
+    #   private address space entirely within Amazon Web Services, but it
+    #   requires more configuration, including establishing a Amazon VPC with
+    #   multiple subnets, a VPC endpoint service, a network load balancer, and
+    #   a verified private DNS name. A public endpoint is simpler to set up,
+    #   but it might be slower and might not fulfill your security
+    #   requirements. You might consider testing with a public endpoint, and
+    #   then establishing a VPC endpoint service for production tasks. Note
+    #   that this choice does not determine the location of the external key
+    #   store proxy. Even if you choose a VPC endpoint service, the proxy can
+    #   be hosted within the VPC or outside of Amazon Web Services such as in

+    # Adds a grant to a KMS key.
+    #
+    # A *grant* is a policy instrument that allows Amazon Web Services
+    # principals to use KMS keys in cryptographic operations. It also can
+    # allow them to view a KMS key (DescribeKey) and create and manage
+    # grants. When authorizing access to a KMS key, grants are considered
+    # along with key policies and IAM policies. Grants are often used for
+    # temporary permissions because you can create one, use its permissions,
+    # and delete it without changing your key policies or IAM policies.
+    #
+    # For detailed information about grants, including grant terminology,
+    # see [Grants in KMS][1] in the <i> <i>Key Management Service Developer
+    # Guide</i> </i>. For examples of working with grants in several
+    # programming languages, see [Programming grants][2].
+    #
+    # The `CreateGrant` operation returns a `GrantToken` and a `GrantId`.
+    #
+    # * When you create, retire, or revoke a grant, there might be a brief
+    #   delay, usually less than five minutes, until the grant is available
+    #   throughout KMS. This state is known as *eventual consistency*. Once
+    #   the grant has achieved eventual consistency, the grantee principal
+    #   can use the permissions in the grant without identifying the grant.
+    #
+    #   However, to use the permissions in the grant immediately, use the
+    #   `GrantToken` that `CreateGrant` returns. For details, see [Using a
+    #   grant token][3] in the <i> <i>Key Management Service Developer
+    #   Guide</i> </i>.
     #
-    # To create a grant that allows a cryptographic operation only when the
-    # encryption context in the operation request matches or includes a
-    # specified encryption context, use the `Constraints` parameter. For
-    # details, see GrantConstraints.
+    # * The `CreateGrant` operation also returns a `GrantId`. You can use
+    #   the `GrantId` and a key identifier to identify the grant in the
+    #   RetireGrant and RevokeGrant operations. To find the grant ID, use
+    #   the ListGrants or ListRetirableGrants operations.
     #
-    # To perform this operation on a CMK in a different AWS account, specify
-    # the key ARN in the value of the `KeyId` parameter. For more
-    # information about grants, see [Grants][1] in the <i> <i>AWS Key
-    # Management Service Developer Guide</i> </i>.
+    # The KMS key that you use for this operation must be in a compatible
+    # key state. For details, see [Key states of KMS keys][4] in the *Key

     #
-    # @option params [String] :description
-    #   A description of the CMK.
     #
-    #   Use a description that helps you decide whether the CMK is appropriate
-    #   for a task.
     #
-    # @option params [String] :key_usage
-    #   The cryptographic operations for which you can use the CMK. The only
-    #   valid value is `ENCRYPT_DECRYPT`, which means you can use the CMK to
-    #   encrypt and decrypt data.
+    # Multi-Region primary keys
+    # Imported key material
     #
-    # @option params [String] :origin
-    #   The source of the key material for the CMK. You cannot change the
-    #   origin after you create the CMK.
+    # : To create a multi-Region *primary key* in the local Amazon Web
+    #   Services Region, use the `MultiRegion` parameter with a value of
+    #   `True`. To create a multi-Region *replica key*, that is, a KMS key
+    #   with the same key ID and key material as a primary key, but in a
+    #   different Amazon Web Services Region, use the ReplicateKey
+    #   operation. To change a replica key to a primary key, and its primary
+    #   key to a replica key, use the UpdatePrimaryRegion operation.
     #
-    #   The default is `AWS_KMS`, which means AWS KMS creates the key material
-    #   in its own key store.
+    #   You can create multi-Region KMS keys for all supported KMS key
+    #   types: symmetric encryption KMS keys, HMAC KMS keys, asymmetric
+    #   encryption KMS keys, and asymmetric signing KMS keys. You can also
+    #   create multi-Region keys with imported key material. However, you
+    #   can't create multi-Region keys in a custom key store.
     #
-    #   When the parameter value is `EXTERNAL`, AWS KMS creates a CMK without
-    #   key material so that you can import key material from your existing
-    #   key management infrastructure. For more information about importing
-    #   key material into AWS KMS, see [Importing Key Material][1] in the *AWS
-    #   Key Management Service Developer Guide*.
+    #   This operation supports *multi-Region keys*, an KMS feature that
+    #   lets you create multiple interoperable KMS keys in different Amazon
+    #   Web Services Regions. Because these KMS keys have the same key ID,
+    #   key material, and other metadata, you can use them interchangeably
+    #   to encrypt data in one Amazon Web Services Region and decrypt it in
+    #   a different Amazon Web Services Region without re-encrypting the
+    #   data or making a cross-Region call. For more information about
+    #   multi-Region keys, see [Multi-Region keys in KMS][4] in the *Key
+    #   Management Service Developer Guide*.
     #
-    #   When the parameter value is `AWS_CLOUDHSM`, AWS KMS creates the CMK in
-    #   an AWS KMS [custom key store][2] and creates its key material in the
-    #   associated AWS CloudHSM cluster. You must also use the
-    #   `CustomKeyStoreId` parameter to identify the custom key store.
     #
     #
+    # : To import your own key material into a KMS key, begin by creating a
+    #   KMS key with no key material. To do this, use the `Origin` parameter
+    #   of `CreateKey` with a value of `EXTERNAL`. Next, use
+    #   GetParametersForImport operation to get a public key and import
+    #   token. Use the wrapping public key to encrypt your key material.
+    #   Then, use ImportKeyMaterial with your import token to import the key
+    #   material. For step-by-step instructions, see [Importing Key
+    #   Material][5] in the <i> <i>Key Management Service Developer
+    #   Guide</i> </i>.

+    #   You can import key material into KMS keys of all supported KMS key
+    #   types: symmetric encryption KMS keys, HMAC KMS keys, asymmetric
+    #   encryption KMS keys, and asymmetric signing KMS keys. You can also

-    # @option params [String] :custom_key_store_id
-    #   Creates the CMK in the specified [custom key store][1] and the key
-    #   material in its associated AWS CloudHSM cluster. To create a CMK in a
-    #   custom key store, you must also specify the `Origin` parameter with a
-    #   value of `AWS_CLOUDHSM`. The AWS CloudHSM cluster that is associated
-    #   with the custom key store must have at least two active HSMs, each in
-    #   a different Availability Zone in the Region.
-    #
-    #   To find the ID of a custom key store, use the DescribeCustomKeyStores
-    #   operation.
     #
-    #   The response includes the custom key store ID and the ID of the AWS
-    #   CloudHSM cluster.
     #
-    #   This operation is part of the [Custom Key Store feature][1] feature in
-    #   AWS KMS, which combines the convenience and extensive integration of

+    # Custom key store
     #
+    # : A [custom key store][7] lets you protect your Amazon Web Services
+    #   resources using keys in a backing key store that you own and manage.
+    #   When you request a cryptographic operation with a KMS key in a
+    #   custom key store, the operation is performed in the backing key
+    #   store using its cryptographic keys.
     #
+    #   KMS supports [CloudHSM key stores][8] backed by an CloudHSM cluster
+    #   and [external key stores][9] backed by an external key manager
+    #   outside of Amazon Web Services. When you create a KMS key in an
+    #   CloudHSM key store, KMS generates an encryption key in the CloudHSM
+    #   cluster and associates it with the KMS key. When you create a KMS
+    #   key in an external key store, you specify an existing encryption key
+    #   in the external key manager.

     #
-    #   Setting this value to true increases the risk that the CMK becomes
-    #   unmanageable. Do not set this value to true indiscriminately.
+    #   Before you create a KMS key in a custom key store, the
+    #   `ConnectionState` of the key store must be `CONNECTED`. To connect
+    #   the custom key store, use the ConnectCustomKeyStore operation. To

     #
-    #    For more information, refer to the scenario in the [Default Key
-    #   Policy][1] section in the <i> <i>AWS Key Management Service Developer
-    #   Guide</i> </i>.
+    #   To create a KMS key in a custom key store, use the

+    #   `SYMMETRIC_DEFAULT`, and the default `KeyUsage` value,
+    #   `ENCRYPT_DECRYPT` to create a symmetric encryption key. No other key
+    #   type is supported in a custom key store.
     #
-    #   Use this parameter only when you include a policy in the request and
-    #   you intend to prevent the principal that is making the request from
-    #   making a subsequent PutKeyPolicy request on the CMK.
+    #   To create a KMS key in an [CloudHSM key store][8], use the `Origin`
+    #   parameter with a value of `AWS_CLOUDHSM`. The CloudHSM cluster that
+    #   is associated with the custom key store must have at least two
+    #   active HSMs in different Availability Zones in the Amazon Web

     #
-    #   The default value is false.
+    #   To create a KMS key in an [external key store][9], use the `Origin`

+    # the *Key Management Service Developer Guide*.
+    #
+    # The `Decrypt` operation also decrypts ciphertext that was encrypted

+    # However, it cannot decrypt symmetric ciphertext produced by other

+    #
+    # If the ciphertext was encrypted under a symmetric encryption KMS key,

-    # Encrypts plaintext into ciphertext by using a customer master key
-    # (CMK). The `Encrypt` operation has two primary use cases:
+    # Gets information about [custom key stores][1] in the account and
+    # Region.
     #
-    # * You can encrypt up to 4 kilobytes (4096 bytes) of arbitrary data
-    #   such as an RSA key, a database password, or other sensitive
-    #   information.
+    # This operation is part of the [custom key stores][1] feature in KMS,
+    # which combines the convenience and extensive integration of KMS with
+    # the isolation and control of a key store that you own and manage.
     #
-    # * You can use the `Encrypt` operation to move encrypted data from one
-    #   AWS region to another. In the first region, generate a data key and
-    #   use the plaintext key to encrypt the data. Then, in the new region,
-    #   call the `Encrypt` method on same plaintext data key. Now, you can
-    #   safely move the encrypted data and encrypted data key to the new
-    #   region, and decrypt in the new region when necessary.
+    # By default, this operation returns information about all custom key
+    # stores in the account and Region. To get only information about a
+    # particular custom key store, use either the `CustomKeyStoreName` or
+    # `CustomKeyStoreId` parameter (but not both).
     #
-    # You don't need use this operation to encrypt a data key within a
-    # region. The GenerateDataKey and GenerateDataKeyWithoutPlaintext
-    # operations return an encrypted data key.
+    # To determine whether the custom key store is connected to its CloudHSM
+    # cluster or external key store proxy, use the `ConnectionState` element
+    # in the response. If an attempt to connect the custom key store failed,
+    # the `ConnectionState` value is `FAILED` and the `ConnectionErrorCode`
+    # element in the response indicates the cause of the failure. For help
+    # interpreting the `ConnectionErrorCode`, see CustomKeyStoresListEntry.
     #
-    # Also, you don't need to use this operation to encrypt data in your
-    # application. You can use the plaintext and encrypted data keys that
-    # the `GenerateDataKey` operation returns.
+    # Custom key stores have a `DISCONNECTED` connection state if the key
+    # store has never been connected or you used the
+    # DisconnectCustomKeyStore operation to disconnect it. Otherwise, the
+    # connection state is CONNECTED. If your custom key store connection
+    # state is `CONNECTED` but you are having trouble using it, verify that
+    # the backing store is active and available. For an CloudHSM key store,
+    # verify that the associated CloudHSM cluster is active and contains the
+    # minimum number of HSMs required for the operation, if any. For an
+    # external key store, verify that the external key store proxy and its
+    # associated external key manager are reachable and enabled.
     #
-    # The result of this operation varies with the key state of the CMK. For
-    # details, see [How Key State Affects Use of a Customer Master Key][1]
-    # in the *AWS Key Management Service Developer Guide*.
+    # For help repairing your CloudHSM key store, see the [Troubleshooting
+    # CloudHSM key stores][2]. For help repairing your external key store,
+    # see the [Troubleshooting external key stores][3]. Both topics are in
+    # the *Key Management Service Developer Guide*.
     #
-    # To perform this operation on a CMK in a different AWS account, specify
-    # the key ARN or alias ARN in the value of the KeyId parameter.
+    # **Cross-account use**: No. You cannot perform this operation on a

-    # We recommend that you use the following pattern to encrypt data
-    # locally in your application:
+    # In general, `DescribeKey` is a non-mutating operation. It returns data
+    # about KMS keys, but doesn't change them. However, Amazon Web Services
+    # services use `DescribeKey` to create [Amazon Web Services managed
+    # keys][2] from a *predefined Amazon Web Services alias* with no key ID.
     #
-    # 1.  Use the `GenerateDataKey` operation to get a data encryption key.
+    # **Cross-account use**: Yes. To perform this operation with a KMS key
+    # in a different Amazon Web Services account, specify the key ARN or
+    # alias ARN in the value of the `KeyId` parameter.

-    # 2.  Use the plaintext data key (returned in the `Plaintext` field of

-    #
-    # This operation is useful for systems that need to encrypt data at some

-    #
-    # It's also useful in distributed systems with different levels of

-    # component of your system creates new containers and stores an
-    # encrypted data key with each container. Then, a different component
-    # puts the data into the containers. That component first decrypts the

-    # data key. In this system, the component that creates the containers

+    #
+    # To generate a data key, specify the symmetric encryption KMS key that

+    #
+    # To generate a 128-bit SM4 data key (China Regions only), specify a

+    #
+    # You can use an optional encryption context to add additional security

+    # you must specify the same encryption context (a case-sensitive exact
+    # match) when decrypting the encrypted data key. Otherwise, the request

+    #
+    # `GenerateDataKey` also supports [Amazon Web Services Nitro
+    # Enclaves][2], which provide an isolated compute environment in Amazon
+    # EC2. To call `GenerateDataKey` for an Amazon Web Services Nitro
+    # enclave, use the [Amazon Web Services Nitro Enclaves SDK][3] or any
+    # Amazon Web Services SDK. Use the `Recipient` parameter to provide the
+    # attestation document for the enclave. `GenerateDataKey` returns a copy
+    # of the data key encrypted under the specified KMS key, as usual. But
+    # instead of a plaintext copy of the data key, the response includes a
+    # copy of the data key encrypted under the public key from the

+    #
+    # **How to use your data key**
+    #
+    # We recommend that you use the following pattern to encrypt data
+    # locally in your application. You can write your own code or use a
+    # client-side encryption library, such as the [Amazon Web Services
+    # Encryption SDK][6], the [Amazon DynamoDB Encryption Client][7], or
+    # [Amazon S3 client-side encryption][8] to do these tasks for you.
+    #
+    # To encrypt data outside of KMS:
+    #
+    # 1.  Use the `GenerateDataKey` operation to get a data key.
+    #
+    # 2.  Use the plaintext data key (in the `Plaintext` field of the
+    #     response) to encrypt your data outside of KMS. Then erase the
+    #     plaintext data key from memory.
+    #
+    # 3.  Store the encrypted data key (in the `CiphertextBlob` field of the
+    #     response) with the encrypted data.
+    #
+    # To decrypt data outside of KMS:
+    #
+    # 1.  Use the Decrypt operation to decrypt the encrypted data key. The
+    #     operation returns a plaintext copy of the data key.
+    #
+    # 2.  Use the plaintext data key to decrypt data outside of KMS, then
+    #     erase the plaintext data key from memory.
+    #
+    # **Cross-account use**: Yes. To perform this operation with a KMS key
+    # in a different Amazon Web Services account, specify the key ARN or
+    # alias ARN in the value of the `KeyId` parameter.
+    #

+    # @option params [required, String] :key_id
+    #   Specifies the symmetric encryption KMS key that encrypts the data key.
+    #   You cannot specify an asymmetric KMS key or a KMS key in a custom key
+    #   store. To get the type and origin of your KMS key, use the DescribeKey
+    #   operation.
+    #
+    #   To specify a KMS key, use its key ID, key ARN, alias name, or alias
+    #   ARN. When using an alias name, prefix it with `"alias/"`. To specify a
+    #   KMS key in a different Amazon Web Services account, you must use the
+    #   key ARN or alias ARN.
+    #
+    #   For example:
+    #
+    #   * Key ID: `1234abcd-12ab-34cd-56ef-1234567890ab`
+    #
+    #   * Key ARN:

+    #   encryption context is supported only on operations with symmetric
+    #   encryption KMS keys. On operations with symmetric encryption KMS keys,
+    #   an encryption context is optional, but it is strongly recommended.
+    #
+    #   For more information, see [Encryption context][1] in the *Key

+    #
+    #   You must specify either the `KeySpec` or the `NumberOfBytes` parameter
+    #   (but not both) in every `GenerateDataKey` request.
+    #
+    # @option params [String] :key_spec

+    #
+    #   When you use this parameter, instead of returning the plaintext data

+    # You must also specify the length of the data key. Use either the
+    # `KeySpec` or `NumberOfBytes` parameters (but not both). For 128-bit
+    # and 256-bit data keys, use the `KeySpec` parameter.
+    #
+    # To generate an SM4 data key (China Regions only), specify a `KeySpec`
+    # value of `AES_128` or `NumberOfBytes` value of `16`. The symmetric

+    #
+    # If the operation succeeds, you will find the encrypted copy of the

+    #
+    # You can use an optional encryption context to add additional security

+    # to encrypt messages and verify signatures outside of KMS. For
+    # information about asymmetric KMS keys, see [Asymmetric KMS keys][1] in
+    # the *Key Management Service Developer Guide*.
+    #
+    # You do not need to download the public key. Instead, you can use the
+    # public key within KMS by calling the Encrypt, ReEncrypt, or Verify
+    # operations with the identifier of an asymmetric KMS key. When you use
+    # the public key within KMS, you benefit from the authentication,
+    # authorization, and logging that are part of every KMS operation. You
+    # also reduce of risk of encrypting data that cannot be decrypted. These
+    # features are not effective outside of KMS.
+    #
+    # To help you use the public key safely outside of KMS, `GetPublicKey`
+    # returns important information about the public key in the response,
+    # including:
+    #
+    # * [KeySpec][2]: The type of key material in the public key, such as
+    #   `RSA_4096` or `ECC_NIST_P521`.
+    #
+    # * [KeyUsage][3]: Whether the key is used for encryption or signing.
+    #
+    # * [EncryptionAlgorithms][4] or [SigningAlgorithms][5]: A list of the
+    #   encryption algorithms or the signing algorithms for the key.
+    #
+    # Although KMS cannot enforce these restrictions on external operations,
+    # it is crucial that you use this information to prevent the public key
+    # from being used improperly. For example, you can prevent a public
+    # signing key from being used encrypt data, or prevent a public key from
+    # being used with an encryption algorithm that is not supported by KMS.
+    # You can also avoid errors, such as using the wrong signing algorithm
+    # in a verification operation.
+    #
+    # To verify a signature outside of KMS with an SM2 public key (China
+    # Regions only), you must specify the distinguishing ID. By default, KMS
+    # uses `1234567812345678` as the distinguishing ID. For more
+    # information, see [Offline verification with SM2 key pairs][6].
+    #
+    # The KMS key that you use for this operation must be in a compatible

+    #
+    #   If you are reimporting the same key material into an existing KMS

+    # reencrypt ciphertext under the same KMS key, such as to change the
+    # [encryption context][2] of a ciphertext.
+    #
+    # The `ReEncrypt` operation can decrypt ciphertext that was encrypted by
+    # using a KMS key in an KMS operation, such as Encrypt or
+    # GenerateDataKey. It can also decrypt ciphertext that was encrypted by
+    # using the public key of an [asymmetric KMS key][3] outside of KMS.
+    # However, it cannot decrypt ciphertext produced by other libraries,
+    # such as the [Amazon Web Services Encryption SDK][4] or [Amazon S3
+    # client-side encryption][5]. These libraries return a ciphertext format
+    # that is incompatible with KMS.
+    #
+    # When you use the `ReEncrypt` operation, you need to provide
+    # information for the decrypt operation and the subsequent encrypt
+    # operation.
+    #
+    # * If your ciphertext was encrypted under an asymmetric KMS key, you
+    #   must use the `SourceKeyId` parameter to identify the KMS key that
+    #   encrypted the ciphertext. You must also supply the encryption
+    #   algorithm that was used. This information is required to decrypt the
+    #   data.
+    #
+    # * If your ciphertext was encrypted under a symmetric encryption KMS
+    #   key, the `SourceKeyId` parameter is optional. KMS can get this
+    #   information from metadata that it adds to the symmetric ciphertext
+    #   blob. This feature adds durability to your implementation by
+    #   ensuring that authorized users can decrypt ciphertext decades after
+    #   it was encrypted, even if they've lost track of the key ID.
+    #   However, specifying the source KMS key is always recommended as a
+    #   best practice. When you use the `SourceKeyId` parameter to specify a
+    #   KMS key, KMS uses only the KMS key you specify. If the ciphertext
+    #   was encrypted under a different KMS key, the `ReEncrypt` operation
+    #   fails. This practice ensures that you use the KMS key that you
+    #   intend.
+    #
+    # * To reencrypt the data, you must use the `DestinationKeyId` parameter
+    #   to specify the KMS key that re-encrypts the data after it is
+    #   decrypted. If the destination KMS key is an asymmetric KMS key, you
+    #   must also provide the encryption algorithm. The algorithm that you
+    #   choose must be compatible with the KMS key.
+    #
+    #   When you use an asymmetric KMS key to encrypt or reencrypt data, be
+    #   sure to record the KMS key and encryption algorithm that you choose.
+    #   You will be required to provide the same KMS key and encryption
+    #   algorithm when you decrypt the data. If the KMS key and algorithm do
+    #   not match the values used to encrypt the data, the decrypt operation
+    #   fails.
+    #
+    #    You are not required to supply the key ID and encryption algorithm
+    #   when you decrypt with symmetric encryption KMS keys because KMS
+    #   stores this information in the ciphertext blob. KMS cannot store
+    #   metadata in ciphertext generated with asymmetric keys. The standard
+    #   format for asymmetric key ciphertext does not include configurable
+    #   fields.
+    #
+    # The KMS key that you use for this operation must be in a compatible
+    # key state. For details, see [Key states of KMS keys][6] in the *Key
+    # Management Service Developer Guide*.
+    #
+    # **Cross-account use**: Yes. The source KMS key and destination KMS key
+    # can be in different Amazon Web Services accounts. Either or both KMS
+    # keys can be in a different account than the caller. To specify a KMS
+    # key in a different account, you must use its key ARN or alias ARN.
+    #
+    # **Required permissions**:
+    #
+    # * [kms:ReEncryptFrom][7] permission on the source KMS key (key policy)
+    #
+    # * [kms:ReEncryptTo][7] permission on the destination KMS key (key
+    #   policy)
+    #
+    # To permit reencryption from or to a KMS key, include the
+    # `"kms:ReEncrypt*"` permission in your [key policy][8]. This permission

+    # Replicates a multi-Region key into the specified Region. This

+    # primary key in a different Region of the same Amazon Web Services
+    # partition. You can create multiple replicas of a primary key, but each
+    # must be in a different Region. To create a multi-Region primary key,
+    # use the CreateKey operation.
+    #
+    # This operation supports *multi-Region keys*, an KMS feature that lets
+    # you create multiple interoperable KMS keys in different Amazon Web
+    # Services Regions. Because these KMS keys have the same key ID, key
+    # material, and other metadata, you can use them interchangeably to
+    # encrypt data in one Amazon Web Services Region and decrypt it in a
+    # different Amazon Web Services Region without re-encrypting the data or
+    # making a cross-Region call. For more information about multi-Region
+    # keys, see [Multi-Region keys in KMS][1] in the *Key Management Service
+    # Developer Guide*.
+    #
+    # A *replica key* is a fully-functional KMS key that can be used
+    # independently of its primary and peer replica keys. A primary key and
+    # its replica keys share properties that make them interoperable. They
+    # have the same [key ID][2] and key material. They also have the same
+    # [key spec][3], [key usage][4], [key material origin][5], and
+    # [automatic key rotation status][6]. KMS automatically synchronizes
+    # these shared properties among related multi-Region keys. All other
+    # properties of a replica key can differ, including its [key policy][7],
+    # [tags][8], [aliases][9], and [Key states of KMS keys][10]. KMS pricing
+    # and quotas for KMS keys apply to each primary key and replica key.
+    #
+    # When this operation completes, the new replica key has a transient key
+    # state of `Creating`. This key state changes to `Enabled` (or
+    # `PendingImport`) after a few seconds when the process of creating the
+    # new replica key is complete. While the key state is `Creating`, you
+    # can manage key, but you cannot yet use it in cryptographic operations.
+    # If you are creating and using the replica key programmatically, retry
+    # on `KMSInvalidStateException` or call `DescribeKey` to check its
+    # `KeyState` value before using it. For details about the `Creating` key
+    # state, see [Key states of KMS keys][10] in the *Key Management Service
+    # Developer Guide*.
+    #
+    # You cannot create more than one replica of a primary key in any
+    # Region. If the Region already includes a replica of the key you're
+    # trying to replicate, `ReplicateKey` returns an
+    # `AlreadyExistsException` error. If the key state of the existing
+    # replica is `PendingDeletion`, you can cancel the scheduled key
+    # deletion (CancelKeyDeletion) or wait for the key to be deleted. The
+    # new replica key you create will have the same [shared properties][11]
+    # as the original replica key.
+    #
+    # The CloudTrail log of a `ReplicateKey` operation records a
+    # `ReplicateKey` operation in the primary key's Region and a CreateKey
+    # operation in the replica key's Region.
+    #
+    # If you replicate a multi-Region primary key with imported key
+    # material, the replica key is created with no key material. You must
+    # import the same key material that you imported into the primary key.
+    # For details, see [Importing key material into multi-Region
+    # keys](kms/latest/developerguide/multi-region-keys-import.html) in the

+    #   property.
+    #
+    #   If you provide a key policy, it must meet the following criteria:
+    #
+    #   * The key policy must allow the calling principal to make a subsequent
+    #     `PutKeyPolicy` request on the KMS key. This reduces the risk that

+    #
+    #   * Each statement in the key policy must contain one or more
+    #     principals. The principals in the key policy must exist and be
+    #     visible to KMS. When you create a new Amazon Web Services principal,
+    #     you might need to enforce a delay before including the new principal

+    #   Setting this value to true increases the risk that the KMS key becomes

+    # @option params [String] :description
+    #   A description of the KMS key. The default value is an empty string (no
+    #   description).
+    #
+    #   Do not include confidential or sensitive information in this field.
+    #   This field may be displayed in plaintext in CloudTrail logs and other
+    #   output.
+    #
+    #   The description is not a shared property of multi-Region keys. You can
+    #   specify the same description or a different description for each key
+    #   in a set of related multi-Region keys. KMS does not synchronize this
+    #   property.
+    #
+    # @option params [Array<Types::Tag>] :tags
+    #   Assigns one or more tags to the replica key. Use this parameter to tag
+    #   the KMS key when it is created. To tag an existing KMS key, use the
+    #   TagResource operation.
+    #
+    #   Do not include confidential or sensitive information in this field.
+    #   This field may be displayed in plaintext in CloudTrail logs and other
+    #   output.
+    #
+    #   <note markdown="1"> Tagging or untagging a KMS key can allow or deny permission to the KMS
+    #   key. For details, see [ABAC for KMS][1] in the *Key Management Service
+    #   Developer Guide*.
+    #
+    #    </note>
+    #
+    #   To use this parameter, you must have [kms:TagResource][2] permission
+    #   in an IAM policy.
+    #
+    #   Tags are not a shared property of multi-Region keys. You can specify
+    #   the same tags or different tags for each key in a set of related
+    #   multi-Region keys. KMS does not synchronize this property.
+    #
+    #   Each tag consists of a tag key and a tag value. Both the tag key and
+    #   the tag value are required, but the tag value can be an empty (null)
+    #   string. You cannot have more than one tag on a KMS key with the same
+    #   tag key. If you specify an existing tag key with a different tag
+    #   value, KMS replaces the current tag value with the specified one.
+    #
+    #   When you add tags to an Amazon Web Services resource, Amazon Web
+    #   Services generates a cost allocation report with usage and costs
+    #   aggregated by tags. Tags can also be used to control access to a KMS
+    #   key. For details, see [Tagging Keys][3].

-    # * The AWS account (root user) under which the grant was created
+    # This operation is part of the [custom key stores][1] feature in KMS,
+    # which combines the convenience and extensive integration of KMS with

+    #
+    # When updating the properties of an external key store, verify that the
+    # updated settings connect your key store, via the external key store
+    # proxy, to the same external key manager as the previous settings, or
+    # to a backup or snapshot of the external key manager with the same
+    # cryptographic keys. If the updated connection settings fail, you can

+    #
+    #  Some external key managers provide a simpler method for updating an

+    #
+    #  When updating an external key store in the KMS console, you can upload

+    # or DISCONNECTED state.
+    #

+  #
+  # ## Request Context
+  # ServiceError objects have a {Aws::Errors::ServiceError#context #context} method that returns
+  # information about the request that generated the error.

+    #   Indicates how KMS communicates with the external key store proxy.
+    #   This parameter is required for custom key stores with a
+    #   `CustomKeyStoreType` of `EXTERNAL_KEY_STORE`.
+    #
+    #   If the external key store proxy uses a public endpoint, specify
+    #   `PUBLIC_ENDPOINT`. If the external key store proxy uses a Amazon VPC
+    #   endpoint service for communication with KMS, specify

+    #   connectivity option][1] in the *Key Management Service Developer
+    #   Guide*.
+    #
+    #   An Amazon VPC endpoint service keeps your communication with KMS in
+    #   a private address space entirely within Amazon Web Services, but it
+    #   requires more configuration, including establishing a Amazon VPC
+    #   with multiple subnets, a VPC endpoint service, a network load
+    #   balancer, and a verified private DNS name. A public endpoint is
+    #   simpler to set up, but it might be slower and might not fulfill your
+    #   security requirements. You might consider testing with a public
+    #   endpoint, and then establishing a VPC endpoint service for
+    #   production tasks. Note that this choice does not determine the
+    #   location of the external key store proxy. Even if you choose a VPC
+    #   endpoint service, the proxy can be hosted within the VPC or outside
+    #   of Amazon Web Services such as in your corporate data center.

+    #   * `XKS_VPC_ENDPOINT_SERVICE_INVALID_CONFIGURATION` — The Amazon VPC
+    #     endpoint service configuration doesn't conform to the
+    #     requirements for an KMS external key store.
+    #
+    #     * The VPC endpoint service must be an endpoint service for
+    #       interface endpoints in the caller's Amazon Web Services
+    #       account.
+    #
+    #     * It must have a network load balancer (NLB) connected to at least
+    #       two subnets, each in a different Availability Zone.
+    #
+    #     * The `Allow principals` list must include the KMS service
+    #       principal for the Region, `cks.kms.<region>.amazonaws.com`, such
+    #       as `cks.kms.us-east-1.amazonaws.com`.
+    #
+    #     * It must *not* require [acceptance][4] of connection requests.
+    #
+    #     * It must have a private DNS name. The private DNS name for an
+    #       external key store with `VPC_ENDPOINT_SERVICE` connectivity must
+    #       be unique in its Amazon Web Services Region.
+    #
+    #     * The domain of the private DNS name must have a [verification
+    #       status][5] of `verified`.
+    #
+    #     * The [TLS certificate][6] specifies the private DNS hostname at
+    #       which the endpoint is reachable.

+    #
+    # In a cryptographic operation, the encryption context in the decryption

+    # order of the pairs can vary.
+    #
+    #  However, in a grant constraint, the key in each key-value pair is not
+    # case sensitive, but the value is case sensitive.
+    #
+    #  To avoid confusion, do not use multiple encryption context pairs that
+    # differ only by case. To require a fully case-sensitive encryption
+    # context, use the `kms:EncryptionContext:` and

+    # @!attribute [rw] policy
+    #   The key policy to attach to the KMS key. This parameter is optional.
+    #   If you do not provide a key policy, KMS attaches the [default key
+    #   policy][1] to the KMS key.
+    #
+    #   The key policy is not a shared property of multi-Region keys. You
+    #   can specify the same key policy or a different key policy for each
+    #   key in a set of related multi-Region keys. KMS does not synchronize
+    #   this property.
+    #
+    #   If you provide a key policy, it must meet the following criteria:
+    #
+    #   * The key policy must allow the calling principal to make a
+    #     subsequent `PutKeyPolicy` request on the KMS key. This reduces the
+    #     risk that the KMS key becomes unmanageable. For more information,
+    #     see [Default key policy][2] in the *Key Management Service
+    #     Developer Guide*. (To omit this condition, set
+    #     `BypassPolicyLockoutSafetyCheck` to true.)
+    #
+    #   * Each statement in the key policy must contain one or more
+    #     principals. The principals in the key policy must exist and be
+    #     visible to KMS. When you create a new Amazon Web Services
+    #     principal, you might need to enforce a delay before including the
+    #     new principal in a key policy because the new principal might not
+    #     be immediately visible to KMS. For more information, see [Changes
+    #     that I make are not always immediately visible][3] in the *Amazon
+    #     Web Services Identity and Access Management User Guide*.

+    #
+    #   * Printable characters in the Basic Latin and Latin-1 Supplement
+    #     character set (through `\u00FF`).

+    #   Tags are not a shared property of multi-Region keys. You can specify
+    #   the same tags or different tags for each key in a set of related
+    #   multi-Region keys. KMS does not synchronize this property.
+    #
+    #   Each tag consists of a tag key and a tag value. Both the tag key and
+    #   the tag value are required, but the tag value can be an empty (null)
+    #   string. You cannot have more than one tag on a KMS key with the same
+    #   tag key. If you specify an existing tag key with a different tag
+    #   value, KMS replaces the current tag value with the specified one.
+    #
+    #   When you add tags to an Amazon Web Services resource, Amazon Web
