NAME

gnutls_psk_set_client_credentials_function - API function

SYNOPSIS

#include <gnutls/gnutls.h>

void gnutls_psk_set_client_credentials_function(gnutls_psk_client_credentials_t cred, gnutls_psk_client_credentials_function * func);

ARGUMENTS

gnutls_psk_client_credentials_t cred: is a gnutls_psk_server_credentials_t type.
gnutls_psk_client_credentials_function * func: is the callback function

DESCRIPTION

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.
