// Returns a unique asymmetric data key pair for use outside of KMS. This
// operation returns a plaintext public key and a copy of the private key that is
// encrypted under the symmetric encryption KMS key you specify. Unlike
// GenerateDataKeyPair , this operation does not return a plaintext private key.
// The bytes in the keys are random; they are not related to the caller or to the
// KMS key that is used to encrypt the private key. You can use the public key that
// GenerateDataKeyPairWithoutPlaintext returns to encrypt data or verify a
// signature outside of 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 encryption KMS key to encrypt the private key in a data
// key pair. You cannot use an asymmetric KMS key or a KMS key in a custom key
// store. To get the type and origin of your KMS key, use the DescribeKey
// operation. Use the KeyPairSpec parameter to choose an RSA or Elliptic Curve
// (ECC) data key pair. In China Regions, you can also choose an SM2 data key pair.
// KMS recommends that you use ECC key pairs for signing, and use RSA and SM2 key
// pairs for either encryption or signing, but not both. However, KMS cannot
// enforce any restrictions on the use of data key pairs outside of KMS.
// GenerateDataKeyPairWithoutPlaintext returns a unique data key pair for each
// request. The bytes in the key are not related to the caller or KMS key that is
// used to encrypt the private key. The public key is a DER-encoded X.509
// SubjectPublicKeyInfo, as specified in RFC 5280 (https://tools.ietf.org/html/rfc5280)
// . 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
// InvalidCiphertextException . For more information, see Encryption Context (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context)
// in the Key Management Service Developer Guide. The KMS key that you use for this
// operation must be in a compatible key state. For details, see Key states of KMS
// keys (https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html) 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. Required
