/**
 * <p>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.</p>
 *          <p>
 *             <code>GenerateDataKeyWithoutPlaintext</code> is identical to the <a>GenerateDataKey</a> operation except that it does not return a plaintext copy of the
 *       data key. </p>
 *          <p>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 <a>Decrypt</a>
 *       operation on the encrypted copy of the key.</p>
 *          <p>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.</p>
 *          <p>To request an asymmetric data key pair, use the <a>GenerateDataKeyPair</a> or
 *         <a>GenerateDataKeyPairWithoutPlaintext</a> operations.</p>
 *          <p>To generate a data key, you must specify the symmetric encryption KMS key that is used to
 *       encrypt the data key. 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 <a>DescribeKey</a>
 *       operation.</p>
 *          <p>You must also specify the length of the data key. Use either the <code>KeySpec</code> or
 *         <code>NumberOfBytes</code> parameters (but not both). For 128-bit and 256-bit data keys, use
 *       the <code>KeySpec</code> parameter.</p>
 *          <p>To generate an SM4 data key (China Regions only), specify a <code>KeySpec</code> value of
 *         <code>AES_128</code> or <code>NumberOfBytes</code> value of <code>16</code>. The symmetric
 *       encryption key used in China Regions to encrypt your data key is an SM4 encryption key.</p>
 *          <p>If the operation succeeds, you will find the encrypted copy of the data key in the
 *         <code>CiphertextBlob</code> field.</p>
 *          <p>You can use an optional encryption context to add additional security to the encryption
 *       operation. If you specify an <code>EncryptionContext</code>, 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 <code>InvalidCiphertextException</code>. For more information, see <a href="https://docs.aws.amazon.com/kms/latest/developerguide/encrypt_context.html">Encryption Context</a> in the
 *       <i>Key Management Service Developer Guide</i>.</p>
 *          <p>The KMS key that you use for this operation must be in a compatible key state. For
 * details, see <a href="https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html">Key states of KMS keys</a> in the <i>Key Management Service Developer Guide</i>.</p>
 *          <p>
 *             <b>Cross-account use</b>: 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 <code>KeyId</code> parameter.</p>
