Simple as telnet
--#--
Once you have OpenSSL built, opening an SSL connection to a server
is as easy as the telnet technique we tried in the <a 
href="/gadgets/http/http.php3?1">HTTP Gadget.</a> The big difference 
is that you get a whole lot more back in the response.<br>
<br>
<code>
openssl s_client -connect server1000:443
</code>
<br>
But opening an SSL connection on a server and making a GET request 
doesn't do much, after awhile. OpenSSL lets you get a close look at 
the server's certificate, but what you really want to do is 
perform an SSL POST. After all, POST-ing to forms is most 
likely where you'll need SSL most.<br>
<br>
For starters, you can try forming the post exactly as you would 
when <a href="/gadgets/http/http.php3?3">telnetting to port 80.</a>
But this can be tedious, so what we need is easily modifiable code 
that performs a secure post for us, just as <a 
href="/gadgets/http/http.php3?5">Sneaky Pete</a> made a standard post.<br>
<br>
To do that, we need to step back and build a gadget in the C 
language that performs a standard non-secure POST. Then we'll 
modify it to call the appropriate OpenSSL functions to do it 
over an SSL socket.<br>
