gnutls_record_get_state - API function

#include <gnutls/gnutls.h>

int gnutls_record_get_state(gnutls_session_t */session/, unsigned read, gnutls_datum_t * mac_key, gnutls_datum_t * IV, gnutls_datum_t * cipher_key, unsigned char [8] seq_number);*

gnutls_session_t session

is a gnutls_session_t type

unsigned read

if non-zero the read parameters are returned, otherwise the write

gnutls_datum_t * mac_key

the key used for MAC (if a MAC is used)

gnutls_datum_t * IV

the initialization vector or nonce used

gnutls_datum_t * cipher_key

the cipher key

unsigned char [8] seq_number

A 64-bit sequence number

This function will return the parameters of the current record state. These are only useful to be provided to an external off-loading device or subsystem. The returned values should be considered constant and valid for the lifetime of the session.

In that case, to sync the state back you must call gnutls_record_set_state().

GNUTLS_E_SUCCESS on success, or an error code.

Since 3.4.0
