    <p>Yes it is; you can use one of <a href="http://www.ararat.cz/synapse/doku.php/public%3ahowto%3asslplugin" rel="nofollow">the plugins</a> shipped with Synapse. As it's also mentioned there, the best is to use the <a href="http://synapse.ararat.cz/doc/help/ssl_openssl.html" rel="nofollow">ssl_openssl.pas</a>. If you decide to follow this one you will need except <a href="http://synapse.ararat.cz/doku.php/start" rel="nofollow">Sysapse</a> also the <a href="http://www.openssl.org/" rel="nofollow">OpenSSL library</a>. Author recommends <a href="ftp://ftp.openssl.org/source/openssl-0.9.7m.tar.gz" rel="nofollow">OpenSSL 0.9.7</a> but as he said on our local forum it seems to works also with OpenSSL 1.0.0d.</p> <p>Note if you are using D2009 up you will need a Unicode support which is not fully supported in version. Download the <a href="http://synalist.svn.sourceforge.net/viewvc/synalist/trunk.tar.gz?view=tar" rel="nofollow">latest version</a> instead.</p> <p>The following sample code receives first 1024 bytes as a response to the <code>HTTP GET</code> method of a secured website using SSL encryption. I've used for it <a href="http://sourceforge.net/projects/gnuwin32/files/openssl/0.9.8h/openssl-0.9.8h-bin.zip/download" rel="nofollow">OpenSSL 0.9.8h</a> with the <a href="http://synalist.svn.sourceforge.net/viewvc/synalist/trunk.tar.gz?view=tar" rel="nofollow">latest version of Synapse</a>. Note you need to put <code>libssl32.dll</code> and <code>libeay32.dll</code> from the <code>OpenSSL</code> package into your output directory to make it work properly. Let's have a form with a button and memo where we receive a result.</p> <pre><code>uses blcksock, synautil, synsock, ssl_openssl, ssl_openssl_lib; procedure TForm1.Button1Click(Sender: TObject); var Socket: TTCPBlockSocket; begin Socket := TTCPBlockSocket.Create; try Socket.Connect('www.yousendit.com', '443'); // connect to the host Socket.SSLDoConnect; // start SSL connection; only server has a certificate if Socket.LastError = 0 then begin Socket.SendString('GET' + CRLF); // request GET method Memo1.Text := Socket.RecvBufferStr(1024, 1000); // receive 1024 bytes end; finally Socket.Free; end; end; </code></pre>

    1. COI appreciate your help. The most confusion for me is that I don't know how can I use the encrypted channel when I don't have certificate. I tried invoke "SSLAcceptConnection" after a connection is accept in server side. And, invoked "SSLDoConnect" in client side after connected to the server. They "seems" to work. But where can I setup the password? I tried "SSL.Password" but seems it's for decrypting certificate. The connection is still established even if the password is different.

    3. COIs there any component/code I can integrate to my program to generate the certificate? I think it's a bit of complicated for users to generate the certificate themselves.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
