* `keys` {Buffer} The keys used for encryption/decryption of the
  [TLS Session Tickets][].

Updates the keys for encryption/decryption of the [TLS Session Tickets][].

*Note*: The key's `Buffer` should be 48 bytes long. See `ticketKeys` option in
[tls.createServer](#tls_tls_createserver_options_secureconnectionlistener) for
more information on how it is used.

*Note*: Changes to the ticket keys are effective only for future server
connections. Existing or currently pending server connections will use the
previous keys.
