All Implemented Interfaces:

AWSKMS
```
public class AWSKMSClient
extends AmazonWebServiceClient
implements AWSKMS
```
Client for accessing AWS Key Management Service. All service calls made using this client are blocking, and will not return until the service call completes.
AWS Key Management Service
AWS Key Management Service (AWS KMS) is an encryption and key management web service. This guide describes the AWS KMS operations that you can call programmatically. For general information about AWS KMS, see the AWS Key Management Service Developer Guide .

AWS provides SDKs that consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .Net, macOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to AWS KMS and other AWS services. For example, the SDKs take care of tasks such as signing requests (see below), managing errors, and retrying requests automatically. For more information about the AWS SDKs, including how to download and install them, see Tools for Amazon Web Services.

We recommend that you use the AWS SDKs to make programmatic API calls to AWS KMS.

Clients must support TLS (Transport Layer Security) 1.0. We recommend TLS 1.2. Clients must also support cipher suites with Perfect Forward Secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE). Most modern systems such as Java 7 and later support these modes.

Signing Requests

Requests must be signed by using an access key ID and a secret access key. We strongly recommend that you do not use your AWS account (root) access key ID and secret key for everyday work with AWS KMS. Instead, use the access key ID and secret access key for an IAM user. You can also use the AWS Security Token Service to generate temporary security credentials that you can use to sign requests.

All AWS KMS operations require Signature Version 4.

Logging API Requests

AWS KMS supports AWS CloudTrail, a service that logs AWS API calls and related events for your AWS account and delivers them to an Amazon S3 bucket that you specify. By using the information collected by CloudTrail, you can determine what requests were made to AWS KMS, who made the request, when it was made, and so on. To learn more about CloudTrail, including how to turn it on and find your log files, see the AWS CloudTrail User Guide.

Additional Resources

For more information about credentials and request signing, see the following:
- AWS Security Credentials - This topic provides general information about the types of credentials used for accessing AWS.
- Temporary Security Credentials - This section of the IAM User Guide describes how to create and use temporary security credentials.
- Signature Version 4 Signing Process - This set of topics walks you through the process of signing a request using an access key ID and a secret access key.
Commonly Used API Operations

Of the API operations discussed in this guide, the following will prove the most useful for most applications. You will likely perform operations other than these, such as creating keys and assigning policies, by using the console.

    Cancels the deletion of a customer master key (CMK). When this operation succeeds, the key state of the CMK is Disabled. To enable the CMK, use EnableKey.
    
    For more information about scheduling and canceling deletion of a CMK, see Deleting Customer Master Keys in the AWS Key Management Service Developer Guide.
    
    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 in the AWS Key Management Service Developer Guide.
    
    Cross-account use: No. You cannot perform this operation on a CMK in a different AWS account.

    Parameters:
    
    cancelKeyDeletionRequest -
    
    Returns:
    
    cancelKeyDeletionResult The response from the CancelKeyDeletion service method, as returned by AWS Key Management Service.
    
    Throws:
    
    NotFoundException
    
    InvalidArnException
    
    DependencyTimeoutException
    
    KMSInternalException
    
    KMSInvalidStateException
    
    AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
    
    AmazonServiceException - If an error response is returned by AWS Key Management Service indicating either a problem with the data in the request, or a server side issue.
  - connectCustomKeyStore
```
public ConnectCustomKeyStoreResult connectCustomKeyStore(ConnectCustomKeyStoreRequest connectCustomKeyStoreRequest)
                                                  throws AmazonServiceException,
                                                         AmazonClientException
```
    Connects or reconnects a custom key store 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 operation. To add HSMs to the cluster, use the CreateHsm operation. Also, the kmsuser crypto user (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 in the AWS Key Management Service Developer Guide.
    
    Cross-account use: No. You cannot perform this operation on a custom key store in a different AWS account.

```
    Creates a friendly name for a customer master key (CMK). You can use an alias to identify a CMK in the AWS KMS console, in the DescribeKey operation and in cryptographic operations, such as Encrypt and GenerateDataKey.
    
    You can also change the CMK that's associated with the alias (UpdateAlias) or delete the alias (DeleteAlias) at any time. These operations don't affect the underlying CMK.
    
    You can associate the alias with any customer managed CMK in the same AWS Region. Each alias is associated with only on CMK at a time, but a CMK can have multiple aliases. A valid CMK is required. You can't create an alias without a CMK.
    
    The alias must be unique in the account and Region, but you can have aliases with the same name in different Regions. For detailed information about aliases, see Using aliases in the AWS Key Management Service Developer Guide.
    
    This operation does not return a response. To get the alias that you created, 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 in the AWS Key Management Service Developer Guide.
    
    Cross-account use: No. You cannot perform this operation on an alias in a different AWS account.
    
    Required permissions
    - kms:CreateAlias on the alias (IAM policy).
    - kms:CreateAlias on the CMK (key policy).
    For details, see Controlling access to aliases in the AWS Key Management Service Developer Guide.

    Creates a custom key store that is associated with an AWS CloudHSM cluster that you own and manage.
    
    This operation is part of the Custom Key Store feature 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.
    
    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 in the AWS Key Management Service Developer Guide.
    
    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.

    Adds a grant to a customer master key (CMK). The grant allows the grantee principal to use the CMK when the conditions specified in the grant are met. When setting permissions, grants are an alternative to key policies.
    
    To create a grant that allows a cryptographic operation only when the request includes a particular encryption context, use the Constraints parameter. For details, see GrantConstraints.
    
    You can create grants on symmetric and asymmetric CMKs. However, if the grant allows an operation that the CMK does not support, CreateGrant fails with a ValidationException.
    - Grants for symmetric CMKs cannot allow operations that are not supported for symmetric CMKs, including Sign, Verify, and GetPublicKey. (There are limited exceptions to this rule for legacy operations, but you should not create a grant for an operation that AWS KMS does not support.)
    - Grants for asymmetric CMKs cannot allow operations that are not supported for asymmetric CMKs, including operations that generate data keys or data key pairs, or operations related to automatic key rotation, imported key material, or CMKs in custom key stores.
    - Grants for asymmetric CMKs with a KeyUsage of ENCRYPT_DECRYPT cannot allow the Sign or Verify operations. Grants for asymmetric CMKs with a KeyUsage of SIGN_VERIFY cannot allow the Encrypt or Decrypt operations.
    - Grants for asymmetric CMKs cannot include an encryption context grant constraint. An encryption context is not supported on asymmetric CMKs.
    For information about symmetric and asymmetric CMKs, see Using Symmetric and Asymmetric CMKs in the AWS Key Management Service Developer Guide. For more information about grants, see Grants in the AWS Key Management Service Developer Guide .

    Creates a unique customer managed customer master key (CMK) in your AWS account and Region.
    
    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 and data keys pairs. 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 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 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, 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 in the AWS Key Management Service Developer Guide .
    
    Cross-account use: No. You cannot use this operation to create a CMK in a different AWS account.
    
    Required permissions: kms:CreateKey (IAM policy). To use the Tags parameter, kms:TagResource (IAM policy). For examples and information about related permissions, see Allow a user to create CMKs in the AWS Key Management Service Developer Guide.

    Decrypts ciphertext that was encrypted by a AWS KMS customer master key (CMK) using any of the following operations:
    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 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 or Amazon S3 client-side encryption. These libraries return a ciphertext format that is incompatible with AWS KMS.
    
    If the ciphertext was encrypted under a symmetric CMK, the KeyId parameter is optional. AWS 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 CMK ID. However, specifying the CMK is always recommended as a best practice. When you use the KeyId parameter to specify a CMK, AWS KMS only uses the CMK you specify. If the ciphertext was encrypted under a different CMK, the Decrypt operation fails. This practice ensures that you use the CMK that you intend.
    
    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. For details, see Best practices for IAM policies in the AWS Key Management Service Developer Guide.
    
    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 in the AWS Key Management Service Developer Guide.

    Deletes a custom key store. This operation does not delete the AWS CloudHSM cluster that is associated with the custom key store, or affect any users or keys in the cluster.
    
    The custom key store that you delete cannot contain any AWS KMS customer master keys (CMKs). Before deleting the key store, verify that you will never need to use any of the CMKs in the key store for any cryptographic operations. Then, use ScheduleKeyDeletion to delete the AWS KMS customer master keys (CMKs) from the key store. When the scheduled waiting period expires, the ScheduleKeyDeletion operation deletes the CMKs. Then it makes a best effort to delete the key material from the associated cluster. However, you might need to manually delete the orphaned key material from the cluster and its backups.
    
    After all CMKs are deleted from AWS KMS, use DisconnectCustomKeyStore to disconnect the key store from AWS KMS. Then, you can delete the custom key store.
    
    Instead of deleting the custom key store, consider using DisconnectCustomKeyStore to disconnect it from AWS KMS. While the key store is disconnected, you cannot create or use the CMKs in the key store. But, you do not need to delete CMKs and you can reconnect a disconnected custom key store at any time.
    
    If the operation succeeds, it returns a JSON object with no properties.

    This operation is part of the Custom Key Store feature 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.
    
    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).

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.
    
    Custom key stores have a DISCONNECTED connection state if the key store has never been connected or you use the DisconnectCustomKeyStore operation to disconnect it. If your custom key store state is CONNECTED but you are having trouble using it, make sure that its associated AWS CloudHSM cluster is active and contains the minimum number of HSMs required for the operation, if any.

    Provides detailed information about a customer master key (CMK). You can run DescribeKey on a customer managed CMK or an AWS managed CMK.
    
    This detailed information includes the key ARN, creation date (and deletion date, if applicable), the key state, and the origin and expiration date (if any) of the key material. For CMKs in custom key stores, it includes information about the custom key store, such as the key store ID and the AWS CloudHSM cluster ID. It includes fields, like KeySpec, that help you distinguish symmetric from asymmetric CMKs. It also provides information that is particularly important to asymmetric CMKs, such as the key usage (encryption or signing) and the encryption algorithms or signing algorithms that the CMK supports.
    
    DescribeKey does not return the following information:
    - Aliases associated with the CMK. To get this information, use ListAliases.
    - Whether automatic key rotation is enabled on the CMK. To get this information, use GetKeyRotationStatus. Also, some key states prevent a CMK from being automatically rotated. For details, see How Automatic Key Rotation Works in AWS Key Management Service Developer Guide.
    - Tags on the CMK. To get this information, use ListResourceTags.
    - Key policies and grants on the CMK. To get this information, use GetKeyPolicy and ListGrants.
    If you call the DescribeKey operation on a predefined AWS alias, that is, an AWS alias with no key ID, AWS KMS creates an AWS managed CMK. Then, it associates the alias with the new CMK, and returns the KeyId and Arn of the new CMK in the response.
    
    Cross-account use: Yes. To perform this operation with a CMK in a different AWS account, specify the key ARN or alias ARN in the value of the KeyId parameter.

    Disconnects the custom key store from its associated AWS CloudHSM cluster. While a custom key store is disconnected, you can manage the custom key store and its customer master keys (CMKs), but you cannot create or use CMKs in the custom key store. You can reconnect the custom key store at any time.
    
    While a custom key store is disconnected, all attempts to create customer master keys (CMKs) in the custom key store or to use existing CMKs in cryptographic operations will fail. This action can prevent users from storing and accessing sensitive data.
    
    To find the connection state of a custom key store, use the DescribeCustomKeyStores operation. To reconnect a custom key store, use the ConnectCustomKeyStore operation.
    
    If the operation succeeds, it returns a JSON object with no properties.
    
    This operation is part of the Custom Key Store feature 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.

    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 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.

    Generates a unique symmetric data key for client-side encryption. This operation returns a plaintext copy of the data key and a copy that is encrypted under a customer master key (CMK) that you specify. You can use the plaintext key to encrypt your data outside of AWS KMS and store the encrypted data key with the encrypted data.
    
    GenerateDataKey returns a unique data key for each request. The bytes in the plaintext key are not related to the caller or the CMK.
    
    To generate a data key, specify the symmetric CMK that will be used to encrypt the data key. You cannot use an asymmetric CMK to generate data keys. To get the type of your CMK, use the DescribeKey operation. 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 get only an encrypted copy of the data key, use GenerateDataKeyWithoutPlaintext. To generate an asymmetric data key pair, use the GenerateDataKeyPair or GenerateDataKeyPairWithoutPlaintext operation. To get a cryptographically secure random byte string, use GenerateRandom.
    
    You can use the optional encryption context to add additional security to the encryption operation. If you specify an EncryptionContext, you must specify the same encryption context (a case-sensitive exact match) when decrypting the encrypted data key. Otherwise, the request to decrypt fails with an InvalidCiphertextException. For more information, see Encryption Context in the AWS Key Management Service Developer Guide.
    
    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 in the AWS Key Management Service Developer Guide.
    
    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, the Amazon DynamoDB Encryption Client, or Amazon S3 client-side encryption 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 operation returns a plaintext copy of the data key.
    2. Use the plaintext data key to decrypt data outside of AWS KMS, then erase the plaintext data key from memory.
    Cross-account use: Yes. To perform this operation with a CMK in a different AWS account, specify the key ARN or alias ARN in the value of the KeyId parameter.

    Generates a unique asymmetric data key pair. The GenerateDataKeyPair operation returns a plaintext public key, a plaintext private key, and a copy of the private key that is encrypted under the symmetric CMK you specify. You can use the data key pair to perform asymmetric cryptography outside of AWS KMS.
    
    GenerateDataKeyPair returns a unique data key pair for each request. The bytes in the keys are not related to the caller or the CMK that is used to encrypt the private key.
    
    You can use the public key that GenerateDataKeyPair returns to encrypt data or verify a signature outside of AWS KMS. Then, store the encrypted private key with the data. When you are ready to decrypt data or sign a message, you can use the Decrypt operation to decrypt the encrypted private key.
    
    To generate a data key pair, you must specify a symmetric customer master key (CMK) to encrypt the private key in a data key pair. You cannot use an asymmetric CMK or a CMK in a custom key store. To get the type and origin of your CMK, use the DescribeKey operation.
    
    If you are using the data key pair to encrypt data, or for any operation where you don't immediately need a private key, consider using the GenerateDataKeyPairWithoutPlaintext operation. GenerateDataKeyPairWithoutPlaintext returns a plaintext public key and an encrypted private key, but omits the plaintext private key that you need only to decrypt ciphertext or sign a message. Later, when you need to decrypt the data or sign a message, use the Decrypt operation to decrypt the encrypted private key in the data key pair.
    
    You can use the optional encryption context to add additional security to the encryption operation. If you specify an EncryptionContext, you must specify the same encryption context (a case-sensitive exact match) when decrypting the encrypted data key.

    Generates a unique symmetric data key. This operation returns a data key that is encrypted under a customer master key (CMK) that you specify. To request an asymmetric data key pair, use the GenerateDataKeyPair or GenerateDataKeyPairWithoutPlaintext operations.
    
    GenerateDataKeyWithoutPlaintext is identical to the GenerateDataKey operation except that returns only the encrypted copy of the data key. This operation is useful for systems that need to encrypt data at some point, but not immediately. When you need to encrypt the data, you call the Decrypt operation on the encrypted copy of the key.
    
    It's also useful in distributed systems with different levels of trust. For example, you might store encrypted data in containers. One 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, uses the plaintext data key to encrypt data, puts the encrypted data into the container, and then destroys the plaintext data key. In this system, the component that creates the containers never sees the plaintext data key.
    
    GenerateDataKeyWithoutPlaintext returns a unique data key for each request. The bytes in the keys are not related to the caller or CMK that is used to encrypt the private key.
    
    To generate a data key, you must specify the symmetric customer master key (CMK) that is used to encrypt the data key. You cannot use an asymmetric CMK to generate a data key. To get the type of your CMK, use the DescribeKey operation.
    
    If the operation succeeds, you will find the encrypted copy of the data key in the CiphertextBlob field.
    
    You can use the optional encryption context to add additional security to the encryption operation. If you specify an EncryptionContext, you must specify the same encryption context (a case-sensitive exact match) when decrypting the encrypted data key.

    Returns the items you need to import key material into a symmetric, customer managed customer master key (CMK). For more information about importing key material into AWS KMS, see Importing Key Material in the AWS Key Management Service Developer Guide.
    
    This operation returns a public key and an import token. Use the public key to encrypt the symmetric key material. Store the import token to send with a subsequent ImportKeyMaterial request.
    
    You must specify the key ID of the symmetric CMK into which you will import key material. This CMK's Origin must be EXTERNAL. You must also specify the wrapping algorithm and type of wrapping key (public key) that you will use to encrypt the key material. You cannot perform this operation on an asymmetric CMK or on any CMK in a different AWS account.
    
    To import key material, you must use the public key and import token from the same response. These items are valid for 24 hours. The expiration date and time appear in the GetParametersForImport response. You cannot use an expired token in an ImportKeyMaterial request. If your key and token expire, send another GetParametersForImport request.
    
    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 in the AWS Key Management Service Developer Guide.

    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 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.
    
    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: The type of key material in the public key, such as RSA_4096 or ECC_NIST_P521.
    - KeyUsage: Whether the key is used for encryption or signing.
    - EncryptionAlgorithms or SigningAlgorithms: 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 in the AWS Key Management Service Developer Guide.
    
    Cross-account use: Yes. To perform this operation with a CMK in a different AWS account, specify the key ARN or alias ARN in the value of the KeyId parameter.

```
    Imports key material into an existing symmetric AWS KMS customer master key (CMK) that was created without key material. After you successfully import key material into a CMK, you can reimport the same key material into that CMK, but you cannot import different key material.
    
    You cannot perform this operation on an asymmetric CMK or on any CMK in a different AWS account. For more information about creating CMKs with no key material and then importing key material, see Importing Key Material in the AWS Key Management Service Developer Guide.
    
    Before using this operation, call GetParametersForImport. Its response includes a public key and an import token. Use the public key to encrypt the key material. Then, submit the import token from the same GetParametersForImport response.
    
    When calling this operation, you must specify the following values:
    - 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 value of its Origin parameter to EXTERNAL. To get the Origin of a CMK, call DescribeKey.)
    - The encrypted key material. To get the public key to encrypt the key material, call GetParametersForImport.
    - The import token that GetParametersForImport returned. You must use a public key and token from the same GetParametersForImport 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 the specified date, and the CMK becomes unusable. To use the CMK again, you must reimport the same key material. The only way to change an expiration date is by reimporting the same key material and specifying a new expiration date.
    When this operation is successful, the key state of the CMK changes from PendingImport to Enabled, and you can use the CMK.
    
    If this operation fails, use the exception to help determine the problem. If the error is related to the key material, the import token, or wrapping key, use GetParametersForImport to get a new public key and import token for the CMK and repeat the import procedure. For help, see How To Import Key Material in the AWS Key Management Service Developer Guide.
    
    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 in the AWS Key Management Service Developer Guide.

  - reEncrypt
```
public ReEncryptResult reEncrypt(ReEncryptRequest reEncryptRequest)
                          throws AmazonServiceException,

```
    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 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 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 outside of AWS KMS. However, it cannot decrypt ciphertext produced by other libraries, such as the AWS Encryption SDK or Amazon S3 client-side encryption. 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 use the SourceKeyId parameter to identify the CMK 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 CMK, the SourceKeyId parameter is optional. AWS 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 CMK ID. However, specifying the source CMK is always recommended as a best practice. When you use the SourceKeyId parameter to specify a CMK, AWS KMS uses only the CMK you specify. If the ciphertext was encrypted under a different CMK, the ReEncrypt operation fails. This practice ensures that you use the CMK that you intend.
    - To reencrypt the data, you must use the DestinationKeyId parameter specify 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.
    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 in the AWS Key Management Service Developer Guide.
    
    Cross-account use: Yes. The source CMK and destination CMK can be in different AWS accounts. Either or both CMKs can be in a different account than the caller.
    
    Required permissions:
    - kms:ReEncryptFrom permission on the source CMK (key policy)
    - kms:ReEncryptTo permission on the destination CMK (key policy)
    To permit reencryption from or to a CMK, include the "kms:ReEncrypt*" permission in your key policy. 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.

    Retires a grant. To clean up, you can retire a grant when you're done using it. You should revoke a grant when you intend to actively deny operations that depend on it. The following are permitted to call this API:
    - The AWS account (root user) under which the grant was created
    - The RetiringPrincipal, if present in the grant
    - The GranteePrincipal, if RetireGrant is an operation specified in the grant
    You must identify the grant to retire by its grant token or by a combination of the grant ID and the Amazon Resource Name (ARN) of the customer master key (CMK). A grant token is a unique variable-length base64-encoded string. A grant ID is a 64 character unique identifier of a grant. The CreateGrant operation returns both.
    
    Cross-account use: Yes. You can retire a grant on a CMK in a different AWS account.

```
    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, 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 from the cluster and its backups.
    
    For more information about scheduling a CMK for deletion, see Deleting Customer Master Keys in the AWS Key Management Service Developer Guide.

```
    Creates a digital signature for a message or message digest by using the private key in an asymmetric CMK. To verify the signature, 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 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 in the AWS Key Management Service Developer Guide.
    
    Cross-account use: Yes. To perform this operation with a CMK in a different AWS account, specify the key ARN or alias ARN in the value of the KeyId parameter.

    Associates an existing AWS KMS alias with a different customer master key (CMK). Each alias is associated with only one CMK at a time, although a CMK can have multiple aliases. The alias and the CMK must be in the same AWS account and region.
    
    The current and 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 errors in code that uses aliases. If you must assign an alias to a different type of CMK, use DeleteAlias to delete the old alias and CreateAlias to create a new alias.
    
    You cannot use UpdateAlias to change an alias name. To change an alias name, use DeleteAlias to delete the old alias and CreateAlias to create a new alias.
    
    Because an alias is not a property of a CMK, you can create, update, and delete 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 of all CMKs in the account, use the ListAliases operation.

    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 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 in the AWS Key Management Service Developer Guide.
    
    Cross-account use: Yes. To perform this operation with a CMK in a different AWS account, specify the key ARN or alias ARN in the value of the KeyId parameter.

    Creates a unique customer managed customer master key (CMK) in your AWS account and Region.
    
    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 and data keys pairs. 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 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 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, 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 in the AWS Key Management Service Developer Guide .
    
    Cross-account use: No. You cannot use this operation to create a CMK in a different AWS account.
    
    Required permissions: kms:CreateKey (IAM policy). To use the Tags parameter, kms:TagResource (IAM policy). For examples and information about related permissions, see Allow a user to create CMKs in the AWS Key Management Service Developer Guide.

```
    Gets a list of aliases in the caller's AWS account and region. For more information about aliases, see CreateAlias.
    
    By default, the ListAliases operation returns all aliases in the account and region. To get only the aliases associated with a particular customer master key (CMK), use the KeyId parameter.
    
    The ListAliases response can include aliases that you created and associated with your customer managed CMKs, and aliases that AWS created and associated with AWS managed CMKs in your account. You can recognize AWS aliases because their names have the format aws/<service-name>, such as aws/dynamodb.
    
    The response might also include aliases that have no TargetKeyId field. These are predefined aliases that AWS has created but has not yet associated with a CMK. Aliases that AWS creates in your account, including predefined aliases, do not count against your AWS KMS aliases quota.
    
    Cross-account use: No. ListAliases does not return aliases in other AWS accounts.
    
    Required permissions: kms:ListAliases (IAM policy)

                        AmazonClientException
```
    Retires a grant. To clean up, you can retire a grant when you're done using it. You should revoke a grant when you intend to actively deny operations that depend on it. The following are permitted to call this API:
    - The AWS account (root user) under which the grant was created
    - The RetiringPrincipal, if present in the grant
    - The GranteePrincipal, if RetireGrant is an operation specified in the grant
    You must identify the grant to retire by its grant token or by a combination of the grant ID and the Amazon Resource Name (ARN) of the customer master key (CMK). A grant token is a unique variable-length base64-encoded string. A grant ID is a 64 character unique identifier of a grant. The CreateGrant operation returns both.
    
    Cross-account use: Yes. You can retire a grant on a CMK in a different AWS account.
    
    Required permissions:: Permission to retire a grant is specified in the grant. You cannot control access to this operation in a policy. For more information, see Using grants in the AWS Key Management Service Developer Guide.

  - getCachedResponseMetadata
```
@Deprecated
public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Deprecated. ResponseMetadata cache can hold up to 50 requests and responses in memory and will cause memory issue. This method now always returns null.
    
    Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.
    
    Specified by:
    
    getCachedResponseMetadata in interface AWSKMS
    
    Parameters:
    
    request - The originally executed request
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
