gnutls_handshake_set_post_client_hello_function - API function
Синопсис (Synopsis)
#include <gnutls/gnutls.h>
void
gnutls_handshake_set_post_client_hello_function(gnutls_session_t
session, gnutls_handshake_simple_hook_func func);
Аргументы (Arguments)
gnutls_session_t session
is a gnutls_session_t type.
gnutls_handshake_simple_hook_func func
is the function to be called
Описание (Description)
This function will set a callback to be called after the client
hello has been received (callback valid in server side only).
This allows the server to adjust settings based on received
extensions.
Those settings could be ciphersuites, requesting certificate, or
anything else except for version negotiation (this is done before
the hello message is parsed).
This callback must return 0 on success or a gnutls error code to
terminate the handshake.
Since GnuTLS 3.3.5 the callback is allowed to return
GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED to put the handshake on
hold. In that case gnutls_handshake() will return
GNUTLS_E_INTERRUPTED and can be resumed when needed.
Предупреждение (Warning)
You should not use this function to terminate the handshake based
on client input unless you know what you are doing. Before the
handshake is finished there is no way to know if there is a
man-in-the-middle attack being performed.
