That is the official version of OpenSSL.  You cannot use that version of the
DLLs with the version of Indy that you are using.  It requires the use of
custom-built versions of those DLLs instead, which are available through
Indy's own website (http://www.indyproject.org/Sockets/SSL.en.aspx).  In
order to use the official OpenSSL DLLs, you would have to upgrade to the
latest Indy 10 version, except that it is not yet available for C++ at this
time.

Then you need to read the documentation, and learn how HTTP works in
general.

From what I can tell from the code you shown, all it is trying to do is
connect to the server in order to obtain certificate information.  It is not
actually requesting any pages from the server.  Is that what you are trying
to accomplish?  If you want to download an actual page, then the code should
look more like the following instead:

    __fastcall TForm1::TForm1(TComponent* Owner)
        : TForm(Owner)
    {
        IdHTTP = new TIdHTTP(this);
        IdSSLIOHandlerSocket = new TIdSSLIOHandlerSocket(IdHTTP);
        IdHTTP->IOHandler = IdSSLIOHandlerSocket;

        IdSSLIOHandlerSocket->SSLOptions->Mode = sslmClient;
        IdSSLIOHandlerSocket->SSLOptions->Method = sslvSSLv23;

        Label2->Caption = "Indy " + IdHTTP->Version;
    }

    void __fastcall TForm1::Button1Click(TObject *Sender)
    {
        Memo1->Clear();

        AnsiString Content = IdHTTP->Get("https://www.verisign.com");
        // use Content as needed ...


Memo1->Lines->Add(IdSSLIOHandlerSocket->SSLSocket->PeerCert->Subject->OneLin
e);
        Memo1->Lines->Add("");

Memo1->Lines->Add(IdSSLIOHandlerSocket->SSLSocket->PeerCert->FingerprintAsSt
ring);
    }

Why are you instantiating those in code instead of dropping them onto the
form at design-time?

> IdHTTP->Host = Host;
> IdHTTP->Port = Port;

You need to specify the Host and Port as a single URL string when calling
Get() or Post().

Because you are using the wrong DLLs.

It is not a class.  It is a global function.  Just include the
IdSSLOpenSSLHeaders.hpp header file into your code, and then call the
function.  For example:

    #include "IdSSLOpenSSLHeaders.hpp"

    try
    {
        // IdHTTP->Connect();
        // or
        // IdHTTP->Get(...);
    }
    catch(const EIdOSSLCouldNotLoadSSLLibrary &)
    {
        Memo1->Lines->Add("SSL Error:");
        Memo1->SelStart = Memo1->GetTextLen();
        Memo1->SelText = WhichFailedToLoad();
    }
