public class GenerateDataKeyPairRequest extends AmazonWebServiceRequest implements java.io.Serializable
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. 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.
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.
Required permissions: kms:GenerateDataKeyPair (key policy)

public java.util.Map<java.lang.String,java.lang.String> getEncryptionContext()
Specifies the encryption context that will be used when encrypting the private key in the data key pair.
An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric CMK, but it is highly recommended.
For more information, see Encryption Context in the AWS Key Management Service Developer Guide.
