How to make HTTPS request with MITM protection?

Question

OpenSSL

We need an example code for downloading a page or file using the https protocol with authentication, that is, so that it would be impossible to wedge into the session (MITM) and forge a response. The whole thing will be on Delphi 7, but the C code will also work, you can use winapi (Win7+) and / or openSSL dll'ku.
