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.
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.

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.void setRegion(Region region)
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. Must not be null and must be a region
where the service is available.Region.getRegion(com.amazonaws.regions.Regions),
Region.createClient(Class,
com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration),
Region.isServiceSupported(String)CancelKeyDeletionResult cancelKeyDeletion(CancelKeyDeletionRequest cancelKeyDeletionRequest)

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.
To map an alias to a different key, call UpdateAlias.

Guide.CreateKeyResult createKey()
createKey(CreateKeyRequest)DecryptResult decrypt(DecryptRequest decryptRequest)
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.
decryptRequest - NotFoundException - The request was rejected because the specified entity or resource
could not be found.DisabledException - The request was rejected because the specified key was marked as
disabled.InvalidCiphertextException - The request was rejected because the specified ciphertext has

EncryptResult encrypt(EncryptRequest encryptRequest)
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 - NotFoundException - The request was rejected because the specified entity or resource
could not be found.DisabledException - The request was rejected because the specified key was marked as
disabled.KeyUnavailableException - The request was rejected because the key was not available. The
request can be retried.DependencyTimeoutException - The system timed out while trying to fulfill the request. The
request can be retried.InvalidKeyUsageException - The request was rejected because the specified KeySpec parameter

of the request is invalid.KMSInternalException - The request was rejected because an internal exception occurred.
The request can be retried.KMSInvalidStateException - The request was rejected because the state of the specified
resource is not valid for this request.
For more information about how key state affects the use of a customer master key (CMK), go to How Key State Affects the Use of a Customer Master Key in the AWS Key Management Service Developer Guide.
GenerateDataKeyResult generateDataKey(GenerateDataKeyRequest generateDataKeyRequest)
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.
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.

ReEncryptResult reEncrypt(ReEncryptRequest reEncryptRequest)
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*" statement in

ScheduleKeyDeletionResult scheduleKeyDeletion(ScheduleKeyDeletionRequest scheduleKeyDeletionRequest)
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.
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.

void updateAlias(UpdateAliasRequest updateAliasRequest)
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.
