According to the article one of the url's where I could get them was
http://www.slproweb.com where I downloaded Win32OpenSSL-0_9_8d.exe.
There was another installer but this one was recommended. Explorer
tells the version of the .dll's is 0.9.8.4

I choosed for that one because I got it all at once: headers, lib and
dll's. (I neaded the headers and lib for the first exercise with
raw sockets. As mentioned that exercise went ok). So -on request- I
installed all in D:\OpenSSL but did not find the .dll's in it. It
appeared that this was one of such installers which ask you for a
destination directory and then copy a whole bunch of files to system32.
Searching for the mentioned .dlls I found them in directories for
FileZilla, php4 and php5. And in system32.

With the Indy example I only needed the .dll's.

So better get them from http://www.indyproject.org?

That I have to investigate further then.

I do not know what I should post or get. I merely followed the example
in the article. This is all the code:

__fastcall TForm1::TForm1(TComponent* Owner)
	: TForm(Owner)
{
	AnsiString Host = "www.verisign.com";
	int Port = 443;

	IdHTTP = new TIdHTTP ( this );
	IdSSLIOHandlerSocket = new TIdSSLIOHandlerSocket ( this );

	IdHTTP->Host = Host;
	IdHTTP->Port = Port;
	IdHTTP->IOHandler = IdSSLIOHandlerSocket;

	IdSSLIOHandlerSocket->SSLOptions->Mode = sslmClient;
	IdSSLIOHandlerSocket->SSLOptions->Method = sslvSSLv23;
						
	Label2->Caption = "Indy " + IdHTTP->Version;
					// 9.0.50			
}

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

	IdHTTP->Connect(); // this brings the exception
			//'Could not load SSL library.'.

	Memo1->Lines->Add (
		IdSSLIOHandlerSocket->SSLSocket->PeerCert->Subject->OneLine );
	Memo1->Lines->Add ( "" );
	Memo1->Lines->Add (
		IdSSLIOHandlerSocket->SSLSocket->PeerCert->FingerprintAsString);
}

Now that is another problem as I do not know if I should instantiate an
instance of that class or that is is part of one of the classes I use here.
Googling for it brings that name used also in the builder groups but there
is not a single code example.

I will first try to get these dll's from the indy website.
