 key. To reference keys in your software, you can use the keyAltName attribute
 specified when creating the key. The following example creates an encryption key
 with an alternative name, which could be done when deploying the application.
 The software then encrypts data by referencing the key by its alternative name.

 To create the encryption key, create a client instance with encryption options
 and create a new data key. You can pass multiple alternate names for this key
 and later reference the key by these alternate names instead of the key ID.
