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.
