OpenSSL is NOT an HTTPS (client or server) library. OpenSSL can
establish a TLS connection, but does not implement anything like
"http.Get". That's what libcurl and the like are for.
If you're willing to roll your own HTTP client code, then you
can use OpenSSL for the TLS part of the HTTPS transaction.
HTTP clients handle all sorts of complications over and above TLS:
* Client requests with bodies
* Chunked transfer encoding
* Content encoding (e.g. gzip)
None of these are in scope for OpenSSL.
