This function can be used to set a callback to retrieve the username and password for client PSK authentication. The callback's function form is: int (*callback)(gnutls_session_t, gnutls_datum_t* username, gnutls_datum_t* key); This callback function has the same semantics as that of gnutls_psk_set_client_credentials_function(), but it allows non-string usernames to be used. The username and key ->data must be allocated using gnutls_malloc(). The username should be an ASCII string or UTF-8 string. In case of a UTF-8 string it is recommended to be following the PRECIS framework for usernames (rfc8265). The callback function will be called once per handshake. The callback function should return 0 on success. -1 indicates an error.
