Overview
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, char** username, gnutls_datum_t* key);
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.
