NAME

gnutls_record_get_state - API function

SYNOPSIS

#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 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

DESCRIPTION

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.

Since 3.4.0
