Ok. Thanks.

BTW, usage of SSL_CTX_new() is different among frontend and backend as
well.

fe-secure.c: SSL_context = SSL_CTX_new(TLSv1_method());
be-secure.c: SSL_context = SSL_CTX_new(SSLv23_method());

In my understanding by using SSLV23_method, it is compatible with
SSLv2, SSLv3, and TLSv1 protocol. So it seems there's no particular
reason to use TLSv1_method(). Am I missing something?
