public interface AWSKMS
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 .
NOTE: AWS provides SDKs that consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .Net, iOS, 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 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, or you can 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 .

void setEndpoint(String endpoint) throws IllegalArgumentException
Callers can pass in just the endpoint (ex: "kms.us-east-1.amazonaws.com/") or a full
URL, including the protocol (ex: "https://kms.us-east-1.amazonaws.com/"). If the
protocol is not specified here, the default protocol from this client's
ClientConfiguration will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
endpoint - The endpoint (ex: "kms.us-east-1.amazonaws.com/") or a full URL,
including the protocol (ex: "https://kms.us-east-1.amazonaws.com/") of
the region specific AWS endpoint this client will communicate
with.IllegalArgumentException - If any problems are detected with the specified endpoint.void setRegion(Region region) throws IllegalArgumentException
setEndpoint(String), sets the
regional endpoint for this client's service calls. Callers can use this
method to control which AWS region they want to work with.
By default, all service endpoints in all regions use the https protocol.
To use http instead, specify it in the ClientConfiguration
supplied at construction.
This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
region - The region this client will communicate with. See
Region.getRegion(com.amazonaws.regions.Regions) for
accessing a given region.IllegalArgumentException - If the given region is null, or if this service isn't
available in the given region. See
Region.isServiceSupported(String)Region.getRegion(com.amazonaws.regions.Regions),
Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)ScheduleKeyDeletionResult scheduleKeyDeletion(ScheduleKeyDeletionRequest scheduleKeyDeletionRequest) throws AmazonServiceException, AmazonClientException
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 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 point to it.
IMPORTANT: Deleting a CMK is a destructive and potentially dangerous operation. When a CMK is deleted, all data that was encrypted under the CMK is rendered unrecoverable. To restrict the use of a CMK without deleting it, use DisableKey.
For more information about scheduling a CMK for deletion, go to Deleting Customer Master Keys in the AWS Key Management Service Developer Guide .
scheduleKeyDeletionRequest - Container for the necessary
parameters to execute the ScheduleKeyDeletion service method on
AWSKMS.DependencyTimeoutExceptionInvalidArnExceptionNotFoundExceptionKMSInvalidStateExceptionKMSInternalExceptionAmazonClientException - 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 AWSKMS indicating
either a problem with the data in the request, or a server side issue.CreateKeyResult createKey(CreateKeyRequest createKeyRequest) throws AmazonServiceException, AmazonClientException
Creates a customer master key. Customer master keys can be used to encrypt small amounts of data (less than 4K) directly, but they are most commonly used to encrypt or envelope data keys that are then used to encrypt customer data. For more information about data keys, see GenerateDataKey and GenerateDataKeyWithoutPlaintext.
createKeyRequest - Container for the necessary parameters to
execute the CreateKey service method on AWSKMS.DependencyTimeoutExceptionMalformedPolicyDocumentExceptionInvalidArnExceptionUnsupportedOperationExceptionKMSInternalExceptionLimitExceededExceptionAmazonClientException - 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 AWSKMS indicating
either a problem with the data in the request, or a server side issue.EncryptResult encrypt(EncryptRequest encryptRequest) throws AmazonServiceException, AmazonClientException
Encrypts plaintext into ciphertext by using a customer master key.
The Encrypt function has two primary use cases:
Unless you are moving encrypted data from one region to another, you
don't use this function to encrypt a generated data key within a
region. You retrieve data keys already encrypted by calling the
GenerateDataKey or GenerateDataKeyWithoutPlaintext function. Data keys
don't need to be encrypted again by calling Encrypt .
If you want to encrypt data locally in your application, you can use
the GenerateDataKey function to return a plaintext data
encryption key and a copy of the key encrypted under the customer
master key (CMK) of your choosing.
encryptRequest - Container for the necessary parameters to
execute the Encrypt service method on AWSKMS.DependencyTimeoutExceptionInvalidGrantTokenExceptionKeyUnavailableExceptionNotFoundExceptionDisabledExceptionInvalidKeyUsageExceptionKMSInvalidStateExceptionKMSInternalExceptionAmazonClientException - 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 AWSKMS indicating
either a problem with the data in the request, or a server side issue.GetKeyPolicyResult getKeyPolicy(GetKeyPolicyRequest getKeyPolicyRequest) throws AmazonServiceException, AmazonClientException
Retrieves a policy attached to the specified key.
getKeyPolicyRequest - Container for the necessary parameters to
execute the GetKeyPolicy service method on AWSKMS.DependencyTimeoutExceptionInvalidArnExceptionNotFoundExceptionKMSInvalidStateExceptionKMSInternalExceptionAmazonClientException - 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 AWSKMS indicating
either a problem with the data in the request, or a server side issue.ListKeysResult listKeys(ListKeysRequest listKeysRequest) throws AmazonServiceException, AmazonClientException
Lists the customer master keys.
listKeysRequest - Container for the necessary parameters to
execute the ListKeys service method on AWSKMS.DependencyTimeoutExceptionKMSInternalExceptionAmazonClientException - 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 AWSKMS indicating
either a problem with the data in the request, or a server side issue.void updateKeyDescription(UpdateKeyDescriptionRequest updateKeyDescriptionRequest) throws AmazonServiceException, AmazonClientException
Updates the description of a key.
updateKeyDescriptionRequest - Container for the necessary
parameters to execute the UpdateKeyDescription service method on
AWSKMS.DependencyTimeoutExceptionInvalidArnExceptionNotFoundExceptionKMSInvalidStateExceptionKMSInternalExceptionAmazonClientException - 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 AWSKMS indicating
either a problem with the data in the request, or a server side issue.GenerateDataKeyResult generateDataKey(GenerateDataKeyRequest generateDataKeyRequest) throws AmazonServiceException, AmazonClientException
Generates a data key that you can use in your application to locally
encrypt data. This call returns a plaintext version of the key in the
Plaintext field of the response object and an encrypted
copy of the key in the CiphertextBlob field. The key is
encrypted by using the master key specified by the KeyId
field. To decrypt the encrypted key, pass it to the
Decrypt API.
We recommend that you use the following pattern to locally encrypt
data: call the GenerateDataKey API, use the key returned
in the Plaintext response field to locally encrypt data,
and then erase the plaintext data key from memory. Store the encrypted
data key (contained in the CiphertextBlob field)
alongside of the locally encrypted data.
NOTE:You should not call the Encrypt function to re-encrypt your data keys within a region. GenerateDataKey always returns the data key encrypted and tied to the customer master key that will be used to decrypt it. There is no need to decrypt it twice.
If you decide to use the optional EncryptionContext
parameter, you must also store the context in full or at least store
enough information along with the encrypted data to be able to
reconstruct the context when submitting the ciphertext to the
Decrypt API. It is a good practice to choose a context
that you can reconstruct on the fly to better secure the ciphertext.
For more information about how this parameter is used, see
Encryption Context
.
To decrypt data, pass the encrypted data key to the
Decrypt API. Decrypt uses the associated
master key to decrypt the encrypted data key and returns it as
plaintext. Use the plaintext data key to locally decrypt your data and
then erase the key from memory. You must specify the encryption
context, if any, that you specified when you generated the key. The
encryption context is logged by CloudTrail, and you can use this log
to help track the use of particular data.

either a problem with the data in the request, or a server side issue.void updateAlias(UpdateAliasRequest updateAliasRequest) throws AmazonServiceException, AmazonClientException
Updates an alias to map it to a different key.
An alias is not a property of a key. Therefore, an alias can be mapped to and unmapped from an existing key without changing the properties of the key.
An alias name can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). An alias must start with the word "alias" followed by a forward slash (alias/). An alias that begins with "aws" after the forward slash (alias/aws...) is reserved by Amazon Web Services (AWS).
The alias and the key it is mapped to must be in the same AWS account and the same region.

Decrypts ciphertext. Ciphertext is plaintext that has been previously encrypted by using any of the following functions:
Note that if a caller has been granted access permissions to all keys
(through, for example, IAM user policies that grant
Decrypt permission on all resources), then ciphertext
encrypted by using keys in other accounts where the key grants access
to the caller can be decrypted. To remedy this, we recommend that you
do not grant Decrypt access in an IAM user policy.
Instead grant Decrypt access only in key policies. If you
must grant Decrypt access in an IAM user policy, you
should scope the resource to specific keys or to specific trusted
accounts.

Encrypts data on the server side with a new customer master key without exposing the plaintext of the data on the client side. The data is first decrypted and then encrypted. This operation can also be used to change the encryption context of a ciphertext.
Unlike other actions, ReEncrypt is authorized twice -
once as ReEncryptFrom on the source key and once as
ReEncryptTo on the destination key. We therefore
recommend that you include the "action":"kms:ReEncrypt*"
