# Connects or reconnects a [custom key store][1] to its associated AWS
# CloudHSM cluster.
#
# The custom key store must be connected before you can create customer
# master keys (CMKs) in the key store or use the CMKs it contains. You
# can disconnect and reconnect a custom key store at any time.
#
# To connect a custom key store, its associated AWS CloudHSM cluster
# must have at least one active HSM. To get the number of active HSMs in
# a cluster, use the [DescribeClusters][2] operation. To add HSMs to the
# cluster, use the [CreateHsm][3] operation. Also, the [ `kmsuser`
# crypto user][4] (CU) must not be logged into the cluster. This
# prevents AWS KMS from using this account to log in.
#
# The connection process can take an extended amount of time to
# complete; up to 20 minutes. This operation starts the connection
# process, but it does not wait for it to complete. When it succeeds,
# this operation quickly returns an HTTP 200 response and a JSON object
# with no properties. However, this response does not indicate that the
# custom key store is connected. To get the connection state of the
# custom key store, use the DescribeCustomKeyStores operation.
#
# During the connection process, AWS KMS finds the AWS CloudHSM cluster
# that is associated with the custom key store, creates the connection
# infrastructure, connects to the cluster, logs into the AWS CloudHSM
# client as the `kmsuser` CU, and rotates its password.
#
# The `ConnectCustomKeyStore` operation might fail for various reasons.
# To find the reason, use the DescribeCustomKeyStores operation and see
# the `ConnectionErrorCode` in the response. For help interpreting the
# `ConnectionErrorCode`, see CustomKeyStoresListEntry.
#
# To fix the failure, use the DisconnectCustomKeyStore operation to
# disconnect the custom key store, correct the error, use the
# UpdateCustomKeyStore operation if necessary, and then use
# `ConnectCustomKeyStore` again.
#
# If you are having trouble connecting or disconnecting a custom key
# store, see [Troubleshooting a Custom Key Store][5] in the *AWS Key

# Creates a display name for a customer managed customer master key
# (CMK). You can use an alias to identify a CMK in [cryptographic
# operations][1], such as Encrypt and GenerateDataKey. You can change
# the CMK associated with the alias at any time.
#
# Aliases are easier to remember than key IDs. They can also help to
# simplify your applications. For example, if you use an alias in your
# code, you can change the CMK your code uses by associating a given
# alias with a different CMK.
#
# To run the same code in multiple AWS regions, use an alias in your
# code, such as `alias/ApplicationKey`. Then, in each AWS Region, create
# an `alias/ApplicationKey` alias that is associated with a CMK in that
# Region. When you run your code, it uses the `alias/ApplicationKey` CMK
# for that AWS Region without any Region-specific code.
#
# This operation does not return a response. To get the alias that you
# created, use the ListAliases operation.
#
# To use aliases successfully, be aware of the following information.
#
# * Each alias points to only one CMK at a time, although a single CMK
# can have multiple aliases. The alias and its associated CMK must be
# in the same AWS account and Region.
#
# * You can associate an alias with any customer managed CMK in the same
# AWS account and Region. However, you do not have permission to
# associate an alias with an [AWS managed CMK][2] or an [AWS owned
# CMK][3].
#
# * To change the CMK associated with an alias, use the UpdateAlias
# operation. The current CMK and the new CMK must be the same type
# (both symmetric or both asymmetric) and they must have the same key
# usage (`ENCRYPT_DECRYPT` or `SIGN_VERIFY`). This restriction
# prevents cryptographic errors in code that uses aliases.
#
# * The alias name must begin with `alias/` followed by a name, such as
# `alias/ExampleAlias`. It can contain only alphanumeric characters,
# forward slashes (/), underscores (\_), and dashes (-). The alias
# name cannot begin with `alias/aws/`. The `alias/aws/` prefix is
# reserved for [AWS managed CMKs][2].
#
# * The alias name must be unique within an AWS Region. However, you can
# use the same alias name in multiple Regions of the same AWS account.
# Each instance of the alias is associated with a CMK in its Region.
#
# * After you create an alias, you cannot change its alias name.
# However, you can use the DeleteAlias operation to delete the alias
# and then create a new alias with the desired name.
#
# * You can use an alias name or alias ARN to identify a CMK in AWS KMS
# [cryptographic operations][1] and in the DescribeKey operation.
# However, you cannot use alias names or alias ARNs in API operations
# that manage CMKs, such as DisableKey or GetKeyPolicy. For
# information about the valid CMK identifiers for each AWS KMS API
# operation, see the descriptions of the `KeyId` parameter in the API
# operation documentation.
#
# Because an alias is not a property of a CMK, you can delete and change
# the aliases of a CMK without affecting the CMK. Also, aliases do not
# appear in the response from the DescribeKey operation. To get the
# aliases and alias ARNs of CMKs in each AWS account and Region, use the
# ListAliases operation.
#
# The CMK that you use for this operation must be in a compatible key
# state. For details, see [How Key State Affects Use of a Customer
# Master Key][4] in the *AWS Key Management Service Developer Guide*.

# Creates a unique customer managed [customer master key][1] (CMK) in
# your AWS account and Region. You cannot use this operation to create a
# CMK in a different AWS account.
#
# You can use the `CreateKey` operation to create symmetric or
# asymmetric CMKs.
#
# * **Symmetric CMKs** contain a 256-bit symmetric key that never leaves
# AWS KMS unencrypted. To use the CMK, you must call AWS KMS. You can
# use a symmetric CMK to encrypt and decrypt small amounts of data,
# but they are typically used to generate [data keys][2] and [data
# keys pairs][3]. For details, see GenerateDataKey and
# GenerateDataKeyPair.
#
# * **Asymmetric CMKs** can contain an RSA key pair or an Elliptic Curve
# (ECC) key pair. The private key in an asymmetric CMK never leaves
# AWS KMS unencrypted. However, you can use the GetPublicKey operation
# to download the public key so it can be used outside of AWS KMS.
# CMKs with RSA key pairs can be used to encrypt or decrypt data or
# sign and verify messages (but not both). CMKs with ECC key pairs can
# be used only to sign and verify messages.
#
# For information about symmetric and asymmetric CMKs, see [Using
# Symmetric and Asymmetric CMKs][4] in the *AWS Key Management Service
# Developer Guide*.
#
# To create different types of CMKs, use the following guidance:
#
# Asymmetric CMKs
#
# : To create an asymmetric CMK, use the `CustomerMasterKeySpec`
# parameter to specify the type of key material in the CMK. Then, use
# the `KeyUsage` parameter to determine whether the CMK will be used
# to encrypt and decrypt or sign and verify. You can't change these
# properties after the CMK is created.
#
#
#
# Symmetric CMKs
#
# : When creating a symmetric CMK, you don't need to specify the
# `CustomerMasterKeySpec` or `KeyUsage` parameters. The default value
# for `CustomerMasterKeySpec`, `SYMMETRIC_DEFAULT`, and the default
# value for `KeyUsage`, `ENCRYPT_DECRYPT`, are the only valid values
# for symmetric CMKs.
#
#
#
# Imported Key Material
#
# : To import your own key material, begin by creating a symmetric CMK
# 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, and use the 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 AWS Key Management Service Developer
# Guide . You cannot import the key material into an
# asymmetric CMK.
#
#
#
# Custom Key Stores
#
# : To create a symmetric CMK in a [custom key store][6], use the
# `CustomKeyStoreId` parameter to specify the custom key store. You
# must also use 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 in different Availability
# Zones in the AWS Region.
#
# You cannot create an asymmetric CMK in a custom key store. For
# information about custom key stores in AWS KMS see [Using Custom Key
# Stores][6] in the AWS Key Management Service Developer
# Guide .

#
# @option params [String] :policy
# The key policy to attach to the CMK.
#
# 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 CMK. This
# reduces the risk that the CMK becomes unmanageable. For more
# information, refer to the scenario in the [Default Key Policy][1]
# section of the AWS Key Management Service Developer Guide
# .
#
# * Each statement in the key policy must contain one or more
# principals. The principals in the key policy must exist and be
# visible to AWS KMS. When you create a new AWS 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 AWS KMS. For more
# information, see [Changes that I make are not always immediately
# visible][2] in the *AWS Identity and Access Management User Guide*.
#
# If you do not provide a key policy, AWS KMS attaches a default key
# policy to the CMK. For more information, see [Default Key Policy][3]
# in the *AWS Key Management Service Developer Guide*.
#
# The key policy size quota is 32 kilobytes (32768 bytes).

#
# @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
# Determines the [cryptographic operations][1] for which you can use the
# CMK. The default value is `ENCRYPT_DECRYPT`. This parameter is
# required only for asymmetric CMKs. You can't change the `KeyUsage`
# value after the CMK is created.
#
# Select only one valid value.
#
# * For symmetric CMKs, omit the parameter or specify `ENCRYPT_DECRYPT`.
#
# * For asymmetric CMKs with RSA key material, specify `ENCRYPT_DECRYPT`
# or `SIGN_VERIFY`.
#
# * For asymmetric CMKs with ECC key material, specify `SIGN_VERIFY`.
#
#
#
# [1]: https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#cryptographic-operations
#
# @option params [String] :customer_master_key_spec
# Specifies the type of CMK to create. The default value,
# `SYMMETRIC_DEFAULT`, creates a CMK with a 256-bit symmetric key for
# encryption and decryption. For help choosing a key spec for your CMK,
# see [How to Choose Your CMK Configuration][1] in the *AWS Key
# Management Service Developer Guide*.
#
# The `CustomerMasterKeySpec` determines whether the CMK contains a
# symmetric key or an asymmetric key pair. It also determines the
# encryption algorithms or signing algorithms that the CMK supports. You
# can't change the `CustomerMasterKeySpec` after the CMK is created. To
# further restrict the algorithms that can be used with the CMK, 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
# *AWS Key Management Service Developer Guide*.
#
# [AWS services that are integrated with AWS KMS][4] use symmetric CMKs
# to protect your data. These services do not support asymmetric CMKs.
# For help determining whether a CMK is symmetric or asymmetric, see
# [Identifying Symmetric and Asymmetric CMKs][5] in the *AWS Key
# Management Service Developer Guide*.
#
# AWS KMS supports the following key specs for CMKs:
#
# * 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.

#
# @option params [String] :origin
# The source of the key material for the CMK. You cannot change the
# origin after you create the CMK. The default is `AWS_KMS`, which means
# AWS KMS creates the key material.
#
# 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 value is valid only for
# symmetric CMKs.
#
# 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. This
# value is valid only for symmetric CMKs.

# @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.
#
# This parameter is valid only for symmetric CMKs. You cannot create an
# asymmetric CMK in a custom key store.
#
# 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

#
#
# [1]: https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html

#
# For more information, refer to the scenario in the [Default Key

# Decrypts ciphertext that was encrypted by a AWS KMS customer master
# key (CMK) using any of the following operations:
#
# * Encrypt
#
# * GenerateDataKey
#
# * GenerateDataKeyPair
#
# * GenerateDataKeyWithoutPlaintext
#
# * GenerateDataKeyPairWithoutPlaintext
#
# You can use this operation to decrypt ciphertext that was encrypted
# under a symmetric or asymmetric CMK. When the CMK is asymmetric, you
# must specify the CMK and the encryption algorithm that was used to
# encrypt the ciphertext. For information about symmetric and asymmetric
# CMKs, see [Using Symmetric and Asymmetric CMKs][1] in the *AWS Key
# Management Service Developer Guide*.
#
# The Decrypt operation also decrypts ciphertext that was encrypted
# outside of AWS KMS by the public key in an AWS KMS asymmetric CMK.
# However, it cannot decrypt ciphertext produced by other libraries,
# such as the [AWS Encryption SDK][2] or [Amazon S3 client-side
# encryption][3]. These libraries return a ciphertext format that is
# incompatible with AWS KMS.
#
# If the ciphertext was encrypted under a symmetric CMK, you do not need
# to specify the CMK or the encryption algorithm. AWS KMS can get this
# information from metadata that it adds to the symmetric ciphertext
# blob. However, if you prefer, you can specify the `KeyId` to ensure
# that a particular CMK is used to decrypt the ciphertext. If you
# specify a different CMK than the one used to encrypt the ciphertext,
# the `Decrypt` operation fails.
#
# Whenever possible, use key policies to give users permission to call
# the Decrypt operation on a particular CMK, instead of using IAM
# policies. Otherwise, you might create an IAM user policy that gives
# the user Decrypt permission on all CMKs. This user could decrypt
# ciphertext that was encrypted by CMKs in other accounts if the key
# policy for the cross-account CMK permits it. If you must use an IAM
# policy for `Decrypt` permissions, limit the user to particular CMKs or
# particular trusted accounts.
#
# The CMK that you use for this operation must be in a compatible key
# state. For details, see [How Key State Affects Use of a Customer
# Master Key][4] in the *AWS Key Management Service Developer Guide*.

# Specifies the encryption context to use when decrypting the data. An

# with a symmetric CMK. The standard asymmetric encryption algorithms
# that AWS KMS uses do not support an encryption context.
#
# An *encryption context* is a collection of non-secret key-value pairs
# that represents additional authenticated data. When you use an
# encryption context to encrypt data, you must specify the same (an
# exact case-sensitive match) encryption context to decrypt the data. An
# encryption context is optional when encrypting with a symmetric CMK,
# but it is highly recommended.
#
# For more information, see [Encryption Context][2] in the *AWS Key

#
# @option params [String] :key_id
# Specifies the customer master key (CMK) that AWS KMS will use to
# decrypt the ciphertext. Enter a key ID of the CMK that was used to
# encrypt the ciphertext.
#
# If you specify a `KeyId` value, the `Decrypt` operation succeeds only
# if the specified CMK was used to encrypt the ciphertext.
#
# This parameter is required only when the ciphertext was encrypted
# under an asymmetric CMK. Otherwise, AWS KMS uses the metadata that it
# adds to the ciphertext blob to determine which CMK was used to encrypt
# the ciphertext. However, you can use this parameter to ensure that a
# particular CMK (of any kind) is used to decrypt the ciphertext.
#
# To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias
# name, or alias ARN. When using an alias name, prefix it with
# `"alias/"`.
#
# 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 CMK, use ListKeys or DescribeKey.
# To get the alias name and alias ARN, use ListAliases.
#
# @option params [String] :encryption_algorithm
# Specifies the encryption algorithm that will be used to decrypt the
# ciphertext. Specify the same algorithm that was used to encrypt the
# data. If you specify a different algorithm, the `Decrypt` operation
# fails.
#
# This parameter is required only when the ciphertext was encrypted

# Encrypts plaintext into ciphertext by using a customer master key
# (CMK). The `Encrypt` operation has two primary use cases:
#
# * You can encrypt small amounts of arbitrary data, such as a personal
# identifier or database password, or other sensitive information.
#
# * You can use the `Encrypt` operation to move encrypted data from one
# AWS Region to another. For example, in Region A, generate a data key
# and use the plaintext key to encrypt your data. Then, in Region A,
# use the `Encrypt` operation to encrypt the plaintext data key under
# a CMK in Region B. Now, you can move the encrypted data and the
# encrypted data key to Region B. When necessary, you can decrypt the
# encrypted data key and the encrypted data entirely within in Region
# B.
#
# You don't need to use the `Encrypt` operation to encrypt a data key.
# The GenerateDataKey and GenerateDataKeyPair operations return a
# plaintext data key and an encrypted copy of that data key.
#
# When you encrypt data, you must specify a symmetric or asymmetric CMK
# to use in the encryption operation. The CMK must have a `KeyUsage`
# value of `ENCRYPT_DECRYPT.` To find the `KeyUsage` of a CMK, use the
# DescribeKey operation.
#
# If you use a symmetric CMK, you can use an encryption context to add
# additional security to your encryption operation. If you specify an
# `EncryptionContext` when encrypting data, you must specify the same
# encryption context (a case-sensitive exact match) when decrypting the
# data. Otherwise, the request to decrypt fails with an
# `InvalidCiphertextException`. For more information, see [Encryption
# Context][1] in the *AWS Key Management Service Developer Guide*.
#
# If you specify an asymmetric CMK, you must also specify the encryption
# algorithm. The algorithm must be compatible with the CMK type.
#
# When you use an asymmetric CMK to encrypt or reencrypt data, be sure
# to record the CMK and encryption algorithm that you choose. You will
# be required to provide the same CMK and encryption algorithm when you
# decrypt the data. If the CMK and algorithm do not match the values
# used to encrypt the data, the decrypt operation fails.
#
# You are not required to supply the CMK ID and encryption algorithm
# when you decrypt with symmetric CMKs because AWS KMS stores this
# information in the ciphertext blob. AWS KMS cannot store metadata in
# ciphertext generated with asymmetric keys. The standard format for
# asymmetric key ciphertext does not include configurable fields.
#
# The maximum size of the data that you can encrypt varies with the type
# of CMK and the encryption algorithm that you choose.

# **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 [AWS Encryption SDK][3],
# the [Amazon DynamoDB Encryption Client][4], or [Amazon S3 client-side
# encryption][5] to do these tasks for you.
#
# To encrypt data outside of AWS 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 AWS 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 AWS KMS:
#
# 1. Use the Decrypt operation to decrypt the encrypted data key. The

# Returns the public key of an asymmetric CMK. Unlike the private key of
# a asymmetric CMK, which never leaves AWS KMS unencrypted, callers with
# `kms:GetPublicKey` permission can download the public key of an
# asymmetric CMK. You can share the public key to allow others to
# encrypt messages and verify signatures outside of AWS KMS. For
# information about symmetric and asymmetric CMKs, see [Using Symmetric
# and Asymmetric CMKs][1] in the *AWS Key Management Service Developer
# Guide*.
#
# You do not need to download the public key. Instead, you can use the
# public key within AWS KMS by calling the Encrypt, ReEncrypt, or Verify
# operations with the identifier of an asymmetric CMK. When you use the
# public key within AWS KMS, you benefit from the authentication,
# authorization, and logging that are part of every AWS KMS operation.
# You also reduce of risk of encrypting data that cannot be decrypted.
# These features are not effective outside of AWS KMS. For details, see
# [Special Considerations for Downloading Public Keys][2].
#
# To help you use the public key safely outside of AWS KMS,
# `GetPublicKey` returns important information about the public key in
# the response, including:
#
# * [CustomerMasterKeySpec][3]\: The type of key material in the public
# key, such as `RSA_4096` or `ECC_NIST_P521`.
#
# * [KeyUsage][4]\: Whether the key is used for encryption or signing.
#
# * [EncryptionAlgorithms][5] or [SigningAlgorithms][6]\: A list of the
# encryption algorithms or the signing algorithms for the key.
#
# Although AWS 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 AWS KMS. You can also avoid errors, such as using the wrong signing
# algorithm in a verification operation.
#
# The CMK that you use for this operation must be in a compatible key
# state. For details, see [How Key State Affects Use of a Customer
# Master Key][7] in the *AWS Key Management Service Developer Guide*.

# * The key ID or key ARN of a CMK with no key material. Its `Origin`
# must be `EXTERNAL`.
#
# To create a CMK with no key material, call CreateKey and set the

# response.
#
# * Whether the key material expires and if so, when. If you set an
# expiration date, AWS KMS deletes the key material from the CMK on

# Decrypts ciphertext and then reencrypts it entirely within AWS KMS.
# You can use this operation to change the customer master key (CMK)
# under which data is encrypted, such as when you [manually rotate][1] a
# CMK or change the CMK that protects a ciphertext. You can also use it
# to reencrypt ciphertext under the same CMK, such as to change the
# [encryption context][2] of a ciphertext.
#
# The `ReEncrypt` operation can decrypt ciphertext that was encrypted by
# using an AWS KMS CMK in an AWS KMS operation, such as Encrypt or
# GenerateDataKey. It can also decrypt ciphertext that was encrypted by
# using the public key of an [asymmetric CMK][3] outside of AWS KMS.
# However, it cannot decrypt ciphertext produced by other libraries,
# such as the [AWS Encryption SDK][4] or [Amazon S3 client-side
# encryption][5]. These libraries return a ciphertext format that is
# incompatible with AWS 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 CMK, you must
# identify the *source CMK*, that is, the CMK that encrypted the
# ciphertext. You must also supply the encryption algorithm that was
# used. This information is required to decrypt the data.
#
# * It is optional, but you can specify a source CMK even when the
# ciphertext was encrypted under a symmetric CMK. This ensures that
# the ciphertext is decrypted only by using a particular CMK. If the
# CMK that you specify cannot decrypt the ciphertext, the `ReEncrypt`
# operation fails.
#
# * To reencrypt the data, you must specify the *destination CMK*, that
# is, the CMK that re-encrypts the data after it is decrypted. You can
# select a symmetric or asymmetric CMK. If the destination CMK is an
# asymmetric CMK, you must also provide the encryption algorithm. The
# algorithm that you choose must be compatible with the CMK.
#
# When you use an asymmetric CMK to encrypt or reencrypt data, be sure
# to record the CMK and encryption algorithm that you choose. You will
# be required to provide the same CMK and encryption algorithm when
# you decrypt the data. If the CMK and algorithm do not match the
# values used to encrypt the data, the decrypt operation fails.
#
# You are not required to supply the CMK ID and encryption algorithm
# when you decrypt with symmetric CMKs because AWS KMS stores this
# information in the ciphertext blob. AWS KMS cannot store metadata in
# ciphertext generated with asymmetric keys. The standard format for
# asymmetric key ciphertext does not include configurable fields.
#
# Unlike other AWS KMS API operations, `ReEncrypt` callers must have two
# permissions:
#
# * `kms:ReEncryptFrom` permission on the source CMK
#
# * `kms:ReEncryptTo` permission on the destination CMK
#
# To permit reencryption from or to a CMK, include the
# `"kms:ReEncrypt*"` permission in your [key policy][6]. This permission
# is automatically included in the key policy when you use the console
# to create a CMK. But you must include it manually when you create a
# CMK programmatically or when you use the PutKeyPolicy operation to set
# a key policy.
#
# The CMK that you use for this operation must be in a compatible key
# state. For details, see [How Key State Affects Use of a Customer
# Master Key][7] in the *AWS Key Management Service Developer Guide*.

#
# An *encryption context* is a collection of non-secret key-value pairs
# that represents additional authenticated data. When you use an

#
# @option params [String] :source_key_id
# A unique identifier for the CMK that is used to decrypt the ciphertext
# before it reencrypts it using the destination CMK.
#
# This parameter is required only when the ciphertext was encrypted
# under an asymmetric CMK. Otherwise, AWS KMS uses the metadata that it
# adds to the ciphertext blob to determine which CMK was used to encrypt
# the ciphertext. However, you can use this parameter to ensure that a
# particular CMK (of any kind) is used to decrypt the ciphertext before
# it is reencrypted.
#
# If you specify a `KeyId` value, the decrypt part of the `ReEncrypt`
# operation succeeds only if the specified CMK was used to encrypt the
# ciphertext.
#
# To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias
# name, or alias ARN. When using an alias name, prefix it with
# `"alias/"`.
#
# 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 CMK, use ListKeys or DescribeKey.
# To get the alias name and alias ARN, use ListAliases.
#
# @option params [required, String] :destination_key_id
# A unique identifier for the CMK that is used to reencrypt the data.
# Specify a symmetric or asymmetric CMK with a `KeyUsage` value of
# `ENCRYPT_DECRYPT`. To find the `KeyUsage` value of a CMK, use the
# DescribeKey operation.
#
# To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias
# name, or alias ARN. When using an alias name, prefix it with
# `"alias/"`. To specify a CMK in a different AWS 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`

#
# To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey.
# To get the alias name and alias ARN, use ListAliases.
#
# @option params [Hash] :destination_encryption_context
# Specifies that encryption context to use when the reencrypting the

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

# Schedules the deletion of a customer master key (CMK). You may provide
# a waiting period, specified in days, before deletion occurs. If you do
# not provide a waiting period, the default period of 30 days is used.
# When this operation is successful, the key state of the CMK changes to
# `PendingDeletion`. Before the waiting period ends, you can use
# CancelKeyDeletion to cancel the deletion of the CMK. After the waiting
# period ends, AWS KMS deletes the CMK and all AWS KMS data associated
# with it, including all aliases that refer to it.
#
# Deleting a CMK is a destructive and potentially dangerous operation.
# When a CMK is deleted, all data that was encrypted under the CMK is
# unrecoverable. To prevent the use of a CMK without deleting it, use
# DisableKey.
#
# If you schedule deletion of a CMK from a [custom key store][1], when
# the waiting period expires, `ScheduleKeyDeletion` deletes the CMK from
# AWS KMS. Then AWS KMS makes a best effort to delete the key material
# from the associated AWS CloudHSM cluster. However, you might need to
# manually [delete the orphaned key material][2] from the cluster and
# its backups.
#
# You cannot perform this operation on a CMK in a different AWS account.
#
# For more information about scheduling a CMK for deletion, see

# Developer Guide*.
#
# The CMK that you use for this operation must be in a compatible key

# Creates a [digital signature][1] for a message or message digest by

# use the Verify operation, or use the public key in the same asymmetric
# CMK outside of AWS KMS. For information about symmetric and asymmetric
# CMKs, see [Using Symmetric and Asymmetric CMKs][2] in the *AWS Key
# Management Service Developer Guide*.
#
# Digital signatures are generated and verified by using asymmetric key
# pair, such as an RSA or ECC pair that is represented by an asymmetric
# customer master key (CMK). The key owner (or an authorized user) uses
# their private key to sign a message. Anyone with the public key can
# verify that the message was signed with that particular private key
# and that the message hasn't changed since it was signed.
#
# To use the `Sign` operation, provide the following information:
#
# * Use the `KeyId` parameter to identify an asymmetric CMK with a
# `KeyUsage` value of `SIGN_VERIFY`. To get the `KeyUsage` value of a
# CMK, use the DescribeKey operation. The caller must have `kms:Sign`
# permission on the CMK.
#
# * Use the `Message` parameter to specify the message or message digest
# to sign. You can submit messages of up to 4096 bytes. To sign a
# larger message, generate a hash digest of the message, and then
# provide the hash digest in the `Message` parameter. To indicate
# whether the message is a full message or a digest, use the
# `MessageType` parameter.
#
# * Choose a signing algorithm that is compatible with the CMK.
#
# When signing a message, be sure to record the CMK and the signing
# algorithm. This information is required to verify the signature.
#
# To verify the signature that this operation generates, use the Verify
# operation. Or use the GetPublicKey operation to download the public
# key and then use the public key to verify the signature outside of AWS
# KMS.
#
# The CMK that you use for this operation must be in a compatible key
# state. For details, see [How Key State Affects Use of a Customer
# Master Key][3] in the *AWS Key Management Service Developer Guide*.

# DescribeKey operation.
#
# To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias
# name, or alias ARN. When using an alias name, prefix it with
# `"alias/"`. To specify a CMK in a different AWS account, you must use
# the key ARN or alias ARN.

# Verifies a digital signature that was generated by the Sign operation.
#
#
#
# Verification confirms that an authorized user signed the message with
# the specified CMK and signing algorithm, and the message hasn't
# changed since it was signed. If the signature is verified, the value
# of the `SignatureValid` field in the response is `True`. If the
# signature verification fails, the `Verify` operation fails with an
# `KMSInvalidSignatureException` exception.
#
# A digital signature is generated by using the private key in an
# asymmetric CMK. The signature is verified by using the public key in
# the same asymmetric CMK. For information about symmetric and
# asymmetric CMKs, see [Using Symmetric and Asymmetric CMKs][1] in the
# *AWS Key Management Service Developer Guide*.
#
# To verify a digital signature, you can use the `Verify` operation.
# Specify the same asymmetric CMK, message, and signing algorithm that
# were used to produce the signature.
#
# You can also verify the digital signature by using the public key of
# the CMK outside of AWS KMS. Use the GetPublicKey operation to download
# the public key in the asymmetric CMK and then use the public key to
# verify the signature outside of AWS KMS. The advantage of using the
# `Verify` operation is that it is performed within AWS KMS. As a
# result, it's easy to call, the operation is performed within the FIPS
# boundary, it is logged in AWS CloudTrail, and you can use key policy
# and IAM policy to determine who is authorized to use the CMK to verify
# signatures.
#
# The CMK that you use for this operation must be in a compatible key
# state. For details, see [How Key State Affects Use of a Customer
# Master Key][2] in the *AWS Key Management Service Developer Guide*.

#
# @option params [required, String] :key_id
# Identifies the asymmetric CMK that will be used to verify the
# signature. This must be the same CMK that was used to generate the
# signature. If you specify a different CMK, the signature verification
# fails.
#
# To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias
# name, or alias ARN. When using an alias name, prefix it with
# `"alias/"`. To specify a CMK in a different AWS 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 CMK, use ListKeys or DescribeKey.
# To get the alias name and alias ARN, use ListAliases.
#
# @option params [required, String, IO] :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.
#
# @option params [String] :message_type
# Tells AWS 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.
#
# @option params [required, String, IO] :signature
# The signature that the `Sign` operation generated.
#
# @option params [required, String] :signing_algorithm
# The signing algorithm that was used to sign the message. If you submit
# a different algorithm, the signature verification fails.
#
# @option params [Array] :grant_tokens
# A list of grant tokens.
#
# For more information, see [Grant Tokens][1] in the *AWS Key Management
# Service Developer Guide*.
