+ * \brief          Load serialised session data into a session structure.
+ *                 On client, this can be used for loading saved sessions
+ *                 before resuming them with mbedstls_ssl_set_session().
+ *                 On server, this can be used for alternative implementations
+ *                 of session cache or session tickets.

+ * \warning        If a peer certificate chain is associated with the session,
+ *                 the serialised state will only contain the peer's
+ *                 end-entity certificate and the result of the chain
+ *                 verification (unless verification was disabled), but not
+ *                 the rest of the chain.
