Is that X509_STORE *the* store in the (relevant) SSL_CTX? [HS] Yes

What cert is xx.cert? [HS] xx.cert is a self-signed certificate file generated 
in Win2012 server.

To verify a server handshake against a store containing one cert, that cert 
must be the CA root cert used by the server cert, and the server must include 
any/all chain certs (which it should, that's best practice, but some don't).

OpenSSL does not currently support trust anchors other than roots, as for 
example IE (or maybe stunnel, I'm not sure) and Firefox do, although there have 
been recent posts indicating it will in the future.
