NAME
       gnutls_ia_extract_inner_secret - API function

SYNOPSIS
       #include <gnutls/extra.h>

       void  gnutls_ia_extract_inner_secret(gnutls_session_t  session,	char *
       buffer);

ARGUMENTS
       gnutls_session_t session

		   is a gnutls_session_t structure.

       char * buffer

		   pre-allocated buffer to hold 48 bytes of inner secret.

DESCRIPTION
       Copy the 48 bytes large inner secret into the specified buffer

       This function is typically used after the  TLS/IA  handshake  has  con-
       cluded.	 The  TLS/IA  inner  secret  can  be used as input to a PRF to
       derive session keys.  Do not use the inner secret directly as a session
       key, because for a resumed session that does not include an application
       phase, the inner secret will be identical to the inner  secret  in  the
       original  session.  It is important to include, for example, the client
       and server randomness when deriving  a  sesssion  key  from  the  inner
       secret.
