gnutls_record_get_state3
Api function
Usage
#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);
Arguments
gnutls_session_t session
|
is a |
|---|---|
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 |
Overview
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().
Returns
GNUTLS_E_SUCCESS on success, or an error code.
