gnutls_ia_extract_inner_secret(3) [suse man page]

gnutls_ia_extract_inner_secret(3)				      gnutls					 gnutls_ia_extract_inner_secret(3)

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 concluded.  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.
