Configuring a pre-shared key file

A pre-shared key file can be used by a server to authentic a client.

A pre-shared key (PSK) is a secret key that can be shared between two devices (for example, a client and a server) that are connected by a secured channel. The PSK is used by the server to authenticate the client. A PSK might be used in environments where it is not possible to use client certificates for mutual authentication. For example, in devices that have firmware in small footprint processors. You can configure a pre-shared key by using REST Administration APIs.
