    # @!attribute [rw] operations
    #   A list of operations that the grant permits.
    #
    #   The operation must be supported on the KMS key. For example, you
    #   cannot create a grant for a symmetric KMS key that allows the Sign
    #   operation, or a grant for an asymmetric KMS key that allows the

    #   @return [Array<String>]
    #
    # @!attribute [rw] constraints
    #   Specifies a grant constraint.
    #
    #   KMS supports the `EncryptionContextEquals` and
    #   `EncryptionContextSubset` grant constraints. Each constraint value
    #   can include up to 8 encryption context pairs. The encryption context
    #   value in each constraint cannot exceed 384 characters.
    #
    #   These grant constraints allow the permissions in the grant only when
    #   the encryption context in the request matches
    #   (`EncryptionContextEquals`) or includes (`EncryptionContextSubset`)
    #   the encryption context specified in this structure. For information
    #   about grant constraints, see [Using grant constraints][1] in the
    #   *Key Management Service Developer Guide*. For more information about
    #   encryption context, see [Encryption Context][2] in the <i> <i>Key
    #   Management Service Developer Guide</i> </i>.
    #
    #   The encryption context grant constraints are supported only on
    #   operations that include an encryption context. You cannot use an
    #   encryption context grant constraint for cryptographic operations
    #   with asymmetric KMS keys or for management operations, such as
    #   DescribeKey or RetireGrant.

    # @!attribute [rw] policy
    #   The key policy to attach to the KMS key.
    #
    #   If you provide a key policy, it must meet the following criteria:
    #
    #   * If you don't set `BypassPolicyLockoutSafetyCheck` to true, the
    #     key policy must allow the principal that is making the `CreateKey`
    #     request to make a subsequent PutKeyPolicy request on the KMS key.
    #     This reduces the risk that the KMS key becomes unmanageable. For
    #     more information, refer to the scenario in the [Default Key
    #     Policy][1] section of the <i> <i>Key Management Service Developer
    #     Guide</i> </i>.
    #
    #   * 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 (for example, an IAM user or role), 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][2] in the *Amazon Web Services Identity and
    #     Access Management User Guide*.
    #
    #   If you do not provide a key policy, KMS attaches a default key
    #   policy to the KMS key. For more information, see [Default Key
    #   Policy][3] in the *Key Management Service Developer Guide*.
    #
    #   The key policy size quota is 32 kilobytes (32768 bytes).

    #   is required only for asymmetric KMS keys. You can't change the
    #   `KeyUsage` value after the KMS key is created.
    #
    #   Select only one valid value.
    #
    #   * For symmetric KMS keys, omit the parameter or specify

    #   Instead, use the `KeySpec` parameter.
    #
    #   The `KeySpec` and `CustomerMasterKeySpec` parameters work the same
    #   way. Only the names differ. We recommend that you use `KeySpec`
    #   parameter in your code. However, to avoid breaking changes, KMS will
    #   support both parameters.
    #   @return [String]
    #
    # @!attribute [rw] key_spec
    #   Specifies the type of KMS key to create. The default value,
    #   `SYMMETRIC_DEFAULT`, creates a KMS key with a 256-bit symmetric key
    #   for encryption and decryption. For help choosing a key spec for your
    #   KMS key, see [How to Choose Your KMS key Configuration][1] in the
    #   <i> <i>Key Management Service Developer Guide</i> </i>.
    #
    #   The `KeySpec` determines whether the KMS key contains a symmetric
    #   key or an asymmetric key pair. It also determines the encryption
    #   algorithms or signing algorithms that the KMS key supports. You
    #   can't change the `KeySpec` after the KMS key is created. 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 [kms:EncryptionAlgorithm][2] or [kms:Signing Algorithm][3] in
    #   the <i> <i>Key Management Service Developer Guide</i> </i>.
    #
    #   [Amazon Web Services services that are integrated with KMS][4] use
    #   symmetric KMS keys to protect your data. These services do not
    #   support asymmetric KMS keys. For help determining whether a KMS key
    #   is symmetric or asymmetric, see [Identifying Symmetric and
    #   Asymmetric KMS keys][5] in the *Key Management Service Developer
    #   Guide*.
    #
    #   KMS supports the following key specs for KMS keys:
    #
    #   * Symmetric key (default)
    #
    #     * `SYMMETRIC_DEFAULT` (AES-256-GCM)
    #
    #     ^
    #
    #   * Asymmetric RSA key pairs
    #
    #     * `RSA_2048`
    #
    #     * `RSA_3072`
    #
    #     * `RSA_4096`
    #
    #   * Asymmetric NIST-recommended elliptic curve key pairs
    #
    #     * `ECC_NIST_P256` (secp256r1)
    #
    #     * `ECC_NIST_P384` (secp384r1)
    #
    #     * `ECC_NIST_P521` (secp521r1)
    #
    #   * Other asymmetric elliptic curve key pairs
    #
    #     * `ECC_SECG_P256K1` (secp256k1), commonly used for
    #       cryptocurrencies.

    #   in a custom key store, you must also specify the `Origin` parameter

    #   associated with the custom key store must have at least two active
    #   HSMs, each in a different Availability Zone in the Region.
    #
    #   This parameter is valid only for symmetric KMS keys and regional KMS

    #   TagResource operation.
    #
    #   <note markdown="1"> Tagging or untagging a KMS key can allow or deny permission to the

    #
    #    </note>
    #
    #   To use this parameter, you must have [kms:TagResource][2] permission
    #   in an IAM policy.
    #
    #   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

    #
    #   For a multi-Region key, set this parameter to `True`. For a

    #
    #   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

    #
    #   You can create and use KMS keys in your custom key stores only when
    #   its connection state is `CONNECTED`.
    #
    #   The value is `DISCONNECTED` if the key store has never been

    #   disconnect it. If the value is `CONNECTED` but you are having
    #   trouble using the custom key store, make sure that its associated
    #   CloudHSM cluster is active and contains at least one active HSM.
    #
    #   A value of `FAILED` indicates that an attempt to connect was

    #   these errors, see [How to Fix a Connection Failure][1] in *Key
    #   Management Service Developer Guide*.
    #
    #   Valid values are:
    #
    #   * `CLUSTER_NOT_FOUND` - KMS cannot find the CloudHSM cluster with
    #     the specified cluster ID.
    #
    #   * `INSUFFICIENT_CLOUDHSM_HSMS` - The associated CloudHSM cluster
    #     does not contain any active HSMs. To connect a custom key store to
    #     its CloudHSM cluster, the cluster must contain at least one active
    #     HSM.
    #
    #   * `INTERNAL_ERROR` - KMS could not complete the request due to an
    #     internal error. Retry the request. For `ConnectCustomKeyStore`
    #     requests, disconnect the custom key store before trying to connect
    #     again.
    #
    #   * `INVALID_CREDENTIALS` - KMS does not have the correct password for
    #     the `kmsuser` crypto user in the CloudHSM cluster. Before you can
    #     connect your custom key store to its CloudHSM cluster, you must
    #     change the `kmsuser` account password and update the key store
    #     password value for the custom key store.
    #
    #   * `NETWORK_ERRORS` - Network errors are preventing KMS from
    #     connecting to the custom key store.
    #
    #   * `SUBNET_NOT_FOUND` - A subnet in the CloudHSM cluster
    #     configuration was deleted. If KMS cannot find all of the subnets
    #     in the cluster configuration, attempts to connect the custom key
    #     store to the CloudHSM cluster fail. To fix this error, create a
    #     cluster from a recent backup and associate it with your custom key
    #     store. (This process creates a new cluster configuration with a
    #     VPC and private subnets.) For details, see [How to Fix a
    #     Connection Failure][1] in the *Key Management Service Developer
    #     Guide*.
    #
    #   * `USER_LOCKED_OUT` - The `kmsuser` CU account is locked out of the
    #     associated CloudHSM cluster due to too many failed password
    #     attempts. Before you can connect your custom key store to its
    #     CloudHSM cluster, you must change the `kmsuser` account password
    #     and update the key store password value for the custom key store.
    #
    #   * `USER_LOGGED_IN` - The `kmsuser` CU account is logged into the the
    #     associated CloudHSM cluster. This prevents KMS from rotating the
    #     `kmsuser` account password and logging into the cluster. Before
    #     you can connect your custom key store to its CloudHSM cluster, you
    #     must log the `kmsuser` CU out of the cluster. If you changed the
    #     `kmsuser` password to log into the cluster, you must also and
    #     update the key store password value for the custom key store. For
    #     help, see [How to Log Out and Reconnect][2] in the *Key Management
    #     Service Developer Guide*.
    #
    #   * `USER_NOT_FOUND` - KMS cannot find a `kmsuser` CU account in the
    #     associated CloudHSM cluster. Before you can connect your custom
    #     key store to its CloudHSM cluster, you must create a `kmsuser` CU
    #     account in the cluster, and then update the key store password
    #     value for the custom key store.

    #
    #   This parameter is required only when the ciphertext was encrypted
    #   under an asymmetric KMS key. If you used a symmetric KMS key, KMS
    #   can get the KMS key from metadata that it adds to the symmetric

    #   practice. This practice ensures that you use the KMS key that you

    #
    #   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:

    # as cryptographic operations with asymmetric KMS keys and management
    # operations, such as DescribeKey or RetireGrant.

    # In a cryptographic operation, the encryption context in the decryption
    # operation must be an exact, case-sensitive match for the keys and

    #  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
    # `kms:EncryptionContextKeys` conditions in an IAM or key policy. For

    #
    #   This parameter is required only when the ciphertext was encrypted

    #   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.

    #   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:

    #
    #   * Alias ARN: `arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias`
    #
    #   To get the key ID and key ARN for a KMS key, use ListKeys or
    #   DescribeKey. To get the alias name and alias ARN, use ListAliases.

    #
    #   A destination encryption context is valid only when the destination

    #
    #   An *encryption context* is a collection of non-secret key-value

    # @!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:
    #
    #   * If you don't set `BypassPolicyLockoutSafetyCheck` to true, the
    #     key policy must give the caller `kms:PutKeyPolicy` permission on
    #     the replica key. This reduces the risk that the KMS key becomes
    #     unmanageable. For more information, refer to the scenario in the
    #     [Default Key Policy][2] section of the <i> <i>Key Management
    #     Service Developer Guide</i> </i>.
    #
    #   * 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 (for example, an IAM user or role), 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 <i> <i>Identity and Access
    #     Management User Guide</i> </i>.

    # @!attribute [rw] description
    #   A description of the KMS key. The default value is an empty string
    #   (no description).
    #
    #   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.
    #   @return [String]
    #
    # @!attribute [rw] 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.
    #
    #   <note markdown="1"> Tagging or untagging a KMS key can allow or deny permission to the
    #   KMS key. For details, see [Using ABAC in 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].

    #   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.

    # @!attribute [rw] key_id
    #   Identifies the asymmetric KMS key that will be used to verify the
    #   signature. This must be the same KMS key that was used to generate
    #   the signature. If you specify a different KMS key, the signature
    #   verification fails.
    #
    #   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:
    #     `arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab`
    #
    #   * Alias name: `alias/ExampleAlias`
    #
    #   * Alias ARN: `arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias`
    #
    #   To get the key ID and key ARN for a KMS key, use ListKeys or
    #   DescribeKey. To get the alias name and alias ARN, use ListAliases.
    #   @return [String]
    #
    # @!attribute [rw] message
    #   Specifies the message that was signed. You can submit a raw message
    #   of up to 4096 bytes, or a hash digest of the message. If you submit
    #   a digest, use the `MessageType` parameter with a value of `DIGEST`.
    #
    #   If the message specified here is different from the message that was
    #   signed, the signature verification fails. A message and its hash
    #   digest are considered to be the same message.
    #   @return [String]
    #
    # @!attribute [rw] message_type
    #   Tells KMS whether the value of the `Message` parameter is a message
    #   or message digest. The default value, RAW, indicates a message. To
    #   indicate a message digest, enter `DIGEST`.
    #
    #   Use the `DIGEST` value only when the value of the `Message`
    #   parameter is a message digest. If you use the `DIGEST` value with a
    #   raw message, the security of the verification operation can be
    #   compromised.
    #   @return [String]
    #
    # @!attribute [rw] signature
    #   The signature that the `Sign` operation generated.
    #   @return [String]
    #
    # @!attribute [rw] signing_algorithm
    #   The signing algorithm that was used to sign the message. If you
    #   submit a different algorithm, the signature verification fails.
    #   @return [String]
    #
    # @!attribute [rw] grant_tokens
    #   A list of grant tokens.
    #
    #   Use a grant token when your permission to call this operation comes
    #   from a new grant that has not yet achieved *eventual consistency*.
    #   For more information, see [Grant token][1] and [Using a grant
    #   token][2] in the *Key Management Service Developer Guide*.
