That will not work. You can do this: #ifdef SSL_MODE_SEND_FALLBACK_SCSV SSL_CTX_set_mode(ctx, SSL_MODE_SEND_FALLBACK_SCSV) #endif But that is not the same thing. You cannot just slip SCSV into an application without code changes to the application and to openssl. -- Principal Security Engineer, Akamai Technologies IM: rs...@jabber.me Twitter: RichSalz
