 **Example 1: To generate a 256-bit symmetric data key**
 
-The following ``generate-data-key`` example requests a 256-bit symmetric data key for use outside of AWS. The command returns a plaintext data key for immediate use and deletion, and a copy of that data key encrypted under the specified KMS key. You can safely store the encrypted data key with the encrypted data.

 To request a 256-bit data key, use the ``key-spec`` parameter with a value of ``AES_256``. To request a 128-bit data key, use the ``key-spec`` parameter with a value of ``AES_128``. For all other data key lengths, use the ``number-of-bytes`` parameter.

+To request a key length other than 128 or 256 bits, use the ``number-of-bytes`` parameter. To request a 512-bit data key, the following example uses the ``number-of-bytes`` parameter with a value of 64 (bytes).
 
 The KMS key you specify must be a symmetric encryption KMS key, that is, a KMS key with a key spec value of SYMMETRIC_DEFAULT.
