NAME

       gnutls_session_get_master_secret  -  get  the  session’s  master secret
       value

SYNOPSIS

       #include <gnutls/gnutls.h>

       const    void    *    gnutls_session_get_master_secret(gnutls_session_t
       session);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t structure.

DESCRIPTION

       Return  a  pointer  to  the  48-byte master secret in the session.  The
       pointer must not be modified or deallocated.

       If a master secret value has not yet been established, the output  will
       be  garbage; in particular, a NULL return value should not be expected.

       Consider using gnutls_prf() rather than extracting  the  master  secret
       and use it to derive further data.

RETURNS

       pointer to master secret data.
