/**
* Interface for accessing KMS.
*
* Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
* {@link com.amazonaws.services.kms.AbstractAWSKMS} instead.
*
*
* Key Management Service
*
* Key Management Service (KMS) is an encryption and key management web service. This guide describes the KMS operations
* that you can call programmatically. For general information about KMS, see the Key Management Service Developer Guide .
*
*
*
* KMS is replacing the term customer master key (CMK) with KMS key and KMS key. The concept has
* not changed. To prevent breaking changes, KMS is keeping some variations of this term.
*
*
* Amazon Web Services 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 KMS and other Amazon Web Services 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 Amazon Web Services
* SDKs, including how to download and install them, see Tools for Amazon Web
* Services.
*
*
*
* We recommend that you use the Amazon Web Services SDKs to make programmatic API calls to KMS.
*
*
* If you need to use FIPS 140-2 validated cryptographic modules when communicating with Amazon Web Services, use the
* FIPS endpoint in your preferred Amazon Web Services Region. For more information about the available FIPS endpoints,
* see Service endpoints in the Key
* Management Service topic of the Amazon Web Services General Reference.
*
*
* All KMS API calls must be signed and be transmitted using Transport Layer Security (TLS). KMS recommends you always
* use the latest supported TLS version. 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 Amazon Web Services account (root) access key ID and secret key for everyday work with KMS. Instead,
* use the access key ID and secret access key for an IAM user. You can also use the Amazon Web Services Security Token
* Service to generate temporary security credentials that you can use to sign requests.
*
*
* All KMS operations require Signature
* Version 4.
*
*
* Logging API Requests
*
*
* KMS supports CloudTrail, a service that logs Amazon Web Services API calls and related events for your Amazon Web
* Services 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 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 CloudTrail User Guide.
*
*
* Additional Resources
*
*
* For more information about credentials and request signing, see the following:
*
*
* -
*
* Amazon Web Services Security
* Credentials - This topic provides general information about the types of credentials used to access Amazon Web
* Services.
*
*
* -
*
* 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.
*
*
* -
*
* Encrypt
*
*
* -
*
* Decrypt
*
*
* -
*
* GenerateDataKey

* Connects or reconnects a custom key store
* to its associated CloudHSM cluster.
*
*
* The custom key store must be connected before you can create KMS keys in the key store or use the KMS keys it
* contains. You can disconnect and reconnect a custom key store at any time.
*
*
* To connect a custom key store, its associated 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 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, KMS finds the CloudHSM cluster that is associated with the custom key store,
* creates the connection infrastructure, connects to the cluster, logs into the 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.

/**
*
* Creates a unique customer managed KMS key in your Amazon
* Web Services account and Region.
*
*
* In addition to the required parameters, you can use the optional parameters to specify a key policy, description,
* tags, and other useful elements for any key type.
*
*
*
* KMS is replacing the term customer master key (CMK) with KMS key and KMS key. The concept
* has not changed. To prevent breaking changes, KMS is keeping some variations of this term.
*
*
*
* To create different types of KMS keys, use the following guidance:
*
*
* - Symmetric encryption KMS key
* -
*
* To create a symmetric encryption KMS key, you aren't required to specify any parameters. The default value for
* KeySpec, SYMMETRIC_DEFAULT, and the default value for KeyUsage,
* ENCRYPT_DECRYPT, create a symmetric encryption KMS key. For technical details, see
* SYMMETRIC_DEFAULT key spec in the Key Management Service Developer Guide.
*
*
* If you need a key for basic encryption and decryption or you are creating a KMS key to protect your resources in
* an Amazon Web Services service, create a symmetric encryption KMS key. The key material in a symmetric encryption
* key never leaves KMS unencrypted. You can use a symmetric encryption KMS key to encrypt and decrypt data up to
* 4,096 bytes, but they are typically used to generate data keys and data keys pairs. For details, see
* GenerateDataKey and GenerateDataKeyPair.
*
*
*
* - Asymmetric KMS keys
* -
*
* To create an asymmetric KMS key, use the KeySpec parameter to specify the type of key material in
* the KMS key. Then, use the KeyUsage parameter to determine whether the KMS key will be used to
* encrypt and decrypt or sign and verify. You can't change these properties after the KMS key is created.
*
*
* Asymmetric KMS keys contain an RSA key pair, Elliptic Curve (ECC) key pair, or an SM2 key pair (China Regions
* only). The private key in an asymmetric KMS key never leaves KMS unencrypted. However, you can use the
* GetPublicKey operation to download the public key so it can be used outside of KMS. KMS keys with RSA or
* SM2 key pairs can be used to encrypt or decrypt data or sign and verify messages (but not both). KMS keys with
* ECC key pairs can be used only to sign and verify messages. For information about asymmetric KMS keys, see Asymmetric KMS keys in
* the Key Management Service Developer Guide.
*
*
*
* - HMAC KMS key
* -
*
* To create an HMAC KMS key, set the KeySpec parameter to a key spec value for HMAC KMS keys. Then set
* the KeyUsage parameter to GENERATE_VERIFY_MAC. You must set the key usage even though
* GENERATE_VERIFY_MAC is the only valid key usage value for HMAC KMS keys. You can't change these
* properties after the KMS key is created.
*
*
* HMAC KMS keys are symmetric keys that never leave KMS unencrypted. You can use HMAC keys to generate
* (GenerateMac) and verify (VerifyMac) HMAC codes for messages up to 4096 bytes.
*
*
* HMAC KMS keys are not supported in all Amazon Web Services Regions. If you try to create an HMAC KMS key in an
* Amazon Web Services Region in which HMAC keys are not supported, the CreateKey operation returns an
* UnsupportedOperationException. For a list of Regions in which HMAC KMS keys are supported, see HMAC keys in KMS in the Key
* Management Service Developer Guide.
*
*
*
* - Multi-Region primary keys
* - Imported key material
* -
*
* To create a multi-Region primary key in the local Amazon Web Services Region, use the
* MultiRegion parameter with a value of True. To create a multi-Region replica
* key, that is, a KMS key with the same key ID and key material as a primary key, but in a different Amazon Web
* Services Region, use the ReplicateKey operation. To change a replica key to a primary key, and its primary
* key to a replica key, use the UpdatePrimaryRegion operation.
*
*
* You can create multi-Region KMS keys for all supported KMS key types: symmetric encryption KMS keys, HMAC KMS
* keys, asymmetric encryption KMS keys, and asymmetric signing KMS keys. You can also create multi-Region keys with
* imported key material. However, you can't create multi-Region keys in a custom key store.
*
*
* This operation supports multi-Region keys, an KMS feature that lets you create multiple interoperable KMS
* keys in different Amazon Web Services Regions. Because these KMS keys have the same key ID, key material, and
* other metadata, you can use them interchangeably to encrypt data in one Amazon Web Services Region and decrypt it
* in a different Amazon Web Services Region without re-encrypting the data or making a cross-Region call. For more
* information about multi-Region keys, see Multi-Region keys in
* KMS in the Key Management Service Developer Guide.
*
*
*
* -
*
* To import your own key material, begin by creating a symmetric encryption KMS key with no key material. To do
* this, use the Origin parameter of CreateKey with a value of EXTERNAL.
* Next, use GetParametersForImport operation to get a public key and import token, 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 Key Management Service Developer Guide .
*
*
* This feature supports only symmetric encryption KMS keys, including multi-Region symmetric encryption KMS keys.
* You cannot import key material into any other type of KMS key.
*
*
* To create a multi-Region primary key with imported key material, use the Origin parameter of
* CreateKey with a value of EXTERNAL and the MultiRegion parameter with a
* value of True. To create replicas of the multi-Region primary key, use the ReplicateKey
* operation. For more information about multi-Region keys, see Multi-Region keys in
* KMS in the Key Management Service Developer Guide.
*
*
*
* - Custom key store
* -
*
* To create a symmetric encryption KMS key 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 CloudHSM cluster that is associated
* with the custom key store must have at least two active HSMs in different Availability Zones in the Amazon Web
* Services Region.
*
*
* Custom key stores support only symmetric encryption KMS keys. You cannot create an HMAC KMS key or an asymmetric
* KMS key in a custom key store. For information about custom key stores in KMS see Custom key stores in
* KMS in the Key Management Service Developer Guide .
*
*
*
*
* Cross-account use: No. You cannot use this operation to create a KMS key in a different Amazon Web
* Services 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 KMS keys in the Key Management Service Developer Guide.

* You can use this operation to decrypt ciphertext that was encrypted under a symmetric encryption KMS key or an

* algorithm that was used to encrypt the ciphertext. For information about asymmetric KMS keys, see Asymmetric KMS keys in
* the Key Management Service Developer Guide.
*
*
* The Decrypt operation also decrypts ciphertext that was encrypted outside of KMS by the public key
* in an KMS asymmetric KMS key. However, it cannot decrypt ciphertext produced by other libraries, such as the Amazon Web Services Encryption SDK
* or Amazon S3 client-side
* encryption. These libraries return a ciphertext format that is incompatible with KMS.
*
*
* If the ciphertext was encrypted under a symmetric encryption KMS key, the KeyId parameter is
* optional. KMS can get this information from metadata that it adds to the symmetric ciphertext blob. This feature
* adds durability to your implementation by ensuring that authorized users can decrypt ciphertext decades after it
* was encrypted, even if they've lost track of the key ID. However, specifying the KMS key is always recommended as
* a best practice. When you use the KeyId parameter to specify a KMS key, KMS only uses the KMS key
* you specify. If the ciphertext was encrypted under a different KMS key, the Decrypt operation fails.
* This practice ensures that you use the KMS key that you intend.
*
*
* Whenever possible, use key policies to give users permission to call the Decrypt operation on a
* particular KMS key, instead of using IAM policies. Otherwise, you might create an IAM user policy that gives the
* user Decrypt permission on all KMS keys. This user could decrypt ciphertext that was encrypted by
* KMS keys in other accounts if the key policy for the cross-account KMS key permits it. If you must use an IAM
* policy for Decrypt permissions, limit the user to particular KMS keys or particular trusted
* accounts. For details, see Best

* Returns a unique symmetric data key for use outside of KMS. This operation returns a data key that is encrypted
* under a symmetric encryption KMS key that you specify. The bytes in the key are random; they are not related to
* the caller or to the KMS key.
*
*
* GenerateDataKeyWithoutPlaintext is identical to the GenerateDataKey operation except that it
* does not return a plaintext 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.
*
*
* To request an asymmetric data key pair, use the GenerateDataKeyPair or

* You cannot use an asymmetric KMS key or a key in a custom key store to generate a data key. To get the type of
* your KMS key, 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 an 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

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

*
*
* This operation supports multi-Region keys, an KMS feature that lets you create multiple interoperable KMS

* KMS in the Key Management Service Developer Guide.
*
*
* A replica key is a fully-functional KMS key that can be used independently of its primary and peer replica
* keys. A primary key and its replica keys share properties that make them interoperable. They have the same key ID and key
* material. They also have the same key spec, key usage, key material origin,
* and automatic key rotation
* status. KMS automatically synchronizes these shared properties among related multi-Region keys. All other
* properties of a replica key can differ, including its key policy, tags, aliases, and Key states of KMS keys. KMS
* pricing and quotas for KMS keys apply to each primary key and replica key.
*
*
* When this operation completes, the new replica key has a transient key state of Creating. This key
* state changes to Enabled (or PendingImport) after a few seconds when the process of
* creating the new replica key is complete. While the key state is Creating, you can manage key, but

* programmatically, retry on KMSInvalidStateException or call DescribeKey to check its
* KeyState value before using it. For details about the Creating key state, see Key states of KMS keys in the
* Key Management Service Developer Guide.
*
*
* You cannot create more than one replica of a primary key in any Region. If the Region already includes a replica
* of the key you're trying to replicate, ReplicateKey returns an AlreadyExistsException
* error. If the key state of the existing replica is PendingDeletion, you can cancel the scheduled key
* deletion (CancelKeyDeletion) or wait for the key to be deleted. The new replica key you create will have

* Schedules the deletion of a KMS key. By default, KMS applies a waiting period of 30 days, but you can specify a
* waiting period of 7-30 days. When this operation is successful, the key state of the KMS key changes to
* PendingDeletion and the key can't be used in any cryptographic operations. It remains in this state
* for the duration of the waiting period. Before the waiting period ends, you can use CancelKeyDeletion to
* cancel the deletion of the KMS key. After the waiting period ends, KMS deletes the KMS key, its key material, and
* all KMS data associated with it, including all aliases that refer to it.
*
*
*
* Deleting a KMS key is a destructive and potentially dangerous operation. When a KMS key is deleted, all data that
* was encrypted under the KMS key is unrecoverable. (The only exception is a multi-Region replica key.) To prevent
* the use of a KMS key without deleting it, use DisableKey.
*
*
*
* If you schedule deletion of a KMS key from a custom key store,
* when the waiting period expires, ScheduleKeyDeletion deletes the KMS key from KMS. Then KMS makes a
* best effort to delete the key material from the associated CloudHSM cluster. However, you might need to manually
* delete
* the orphaned key material from the cluster and its backups.
*
*
* You can schedule the deletion of a multi-Region primary key and its replica keys at any time. However, KMS will
* not delete a multi-Region primary key with existing replica keys. If you schedule the deletion of a primary key
* with replicas, its key state changes to PendingReplicaDeletion and it cannot be replicated or used
* in cryptographic operations. This status can continue indefinitely. When the last of its replicas keys is deleted
* (not just scheduled), the key state of the primary key changes to PendingDeletion and its waiting
* period (PendingWindowInDays) begins. For details, see Deleting multi-Region
* keys in the Key Management Service Developer Guide.
*
*
* For more information about scheduling a KMS key for deletion, see Deleting KMS keys in the

* Creates a digital signature for a message or

* Verify operation, or use the public key in the same asymmetric KMS key outside of KMS. For information
* about asymmetric KMS keys, see Asymmetric KMS keys in
* the 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 KMS key. 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 KMS key with a KeyUsage value of
* SIGN_VERIFY. To get the KeyUsage value of a KMS key, use the DescribeKey
* operation. The caller must have kms:Sign permission on the KMS key.
*
*
* -
*
* 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 KMS key.
*
*
*
*
*
* When signing a message, be sure to record the KMS key and the signing algorithm. This information is required to
* verify the signature.
*
*
*
* Best practices recommend that you limit the time during which any signature is effective. This deters an attack
* where the actor uses a signed message to establish validity repeatedly or long after the message is superseded.
* Signatures do not include a timestamp, but you can include a timestamp in the signed message to help you detect
* when its time to refresh the signature.
*

/**
*
* Verifies a digital signature that was generated by the Sign operation.
*
*
*
* Verification confirms that an authorized user signed the message with the specified KMS key 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 KMS key. The signature is verified by
* using the public key in the same asymmetric KMS key. For information about asymmetric KMS keys, see Asymmetric KMS keys in
* the Key Management Service Developer Guide.
*
*
* To verify a digital signature, you can use the Verify operation. Specify the same asymmetric KMS
* key, 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 KMS key outside of KMS. Use the
* GetPublicKey operation to download the public key in the asymmetric KMS key and then use the public key to
* verify the signature outside of KMS. To verify a signature outside of KMS with an SM2 public key, you must
* specify the distinguishing ID. By default, KMS uses 1234567812345678 as the distinguishing ID. For
* more information, see Offline verification with SM2 key pairs in Key Management Service Developer Guide. The advantage of
* using the Verify operation is that it is performed within KMS. As a result, it's easy to call, the
* operation is performed within the FIPS boundary, it is logged in CloudTrail, and you can use key policy and IAM
* policy to determine who is authorized to use the KMS key to verify signatures.
*
*
* The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of KMS keys in the
* Key Management Service Developer Guide.
*
*
* Cross-account use: Yes. To perform this operation with a KMS key in a different Amazon Web Services
* account, specify the key ARN or alias ARN in the value of the KeyId parameter.
