Examples

Example 1: To generate a data key

The following example generates a 256-bit symmetric data encryption key (data key) in two formats. One is the unencrypted (plainext) data key, and the other is the data key encrypted with the specified customer master key (CMK).

$result = $client->generateDataKey([
    'KeyId' => 'alias/ExampleAlias', // The identifier of the CMK to use to encrypt the data key. You can use the key ID or Amazon Resource Name (ARN) of the CMK, or the name or ARN of an alias that refers to the CMK.
    'KeySpec' => 'AES_256', // Specifies the type of data key to return.
