NAME gnutls_sign_callback_set - API function

SYNOPSIS #include <gnutls/gnutls.h>

void gnutls_sign_callback_set(gnutls_session_t session, gnutls_sign_func sign_func, void * userdata);

ARGUMENTS gnutls_session_t session is a gnutls session

gnutls_sign_func sign_func function pointer to application s sign callback.

void * userdata void pointer that will be passed to sign callback.

DESCRIPTION Set the callback function. The function must have this prototype:

typedef int (*gnutls_sign_func) (gnutls_session_t session, void *user- data, gnutls_certificate_type_t cert_type, const gnutls_datum_t * cert, const gnutls_datum_t * hash, gnutls_datum_t * signature);

The userdata parameter is passed to the sign_func verbatim, and can be used to store application-specific data needed in the callback func- tion. See also gnutls_sign_callback_get().

DEPRECATED Use the PKCS 11 interfaces instead.
