NAME
gnutls_psk_set_client_credentials_function3 - API function
SYNOPSIS
#include <gnutls/gnutls.h>
void
gnutls_psk_set_client_credentials_function3(3)
cred, gnutls_psk_client_credentials_function3 * func);
ARGUMENTS
gnutls_psk_client_credentials_t cred
is a gnutls_psk_server_credentials_t type.
gnutls_psk_client_credentials_function3 * 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, gnutls_datum_t* username,
gnutls_datum_t* key, gnutls_datum_t* context, gnutls_psk_key_flags
*flags);
This callback function has the same semantics as that of
gnutls_psk_set_client_credentials_function2(), but it returns flags
associated with the key. The callback may import external PSK using
the method described in RFC 9258 by using
gnutls_psk_format_imported_identity().
The data field of username , key , and context 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.
