Change your Java code to use secure sockets layer

If your code already uses socket factories to create its sockets, then you can add secure socket layer (SSL) support to your program. If your code does not already use socket factories, see Change your Java™ code to use socket factories.

To change your code to use SSL, perform the following steps:

Import javax.net.ssl.* to add SSL support:
```
import javax.net.ssl.*;
```
Declare a SocketFactory by using SSLSocketFactory to initialize it:
```
SocketFactory newSF = SSLSocketFactory.getDefault();
```
Use your new SocketFactory to initialize your sockets the same way that you used your old SocketFactory:
```
Socket s = newSF.createSocket(args[0], serverPort);
```

Your code now uses SSL support. You do not need to make any other changes to your code.

See Examples: Change your Java client to use secure sockets layer and Examples: Change your Java server to use secure sockets layer for example code.

Examples: Change your Java server to use secure sockets layer
These examples show you how to change one class, named factorySocketServer, to use secure sockets layer (SSL).
Examples: Change your Java client to use secure sockets layer
These examples show you how to change one class, named factorySocketClient, to use secure sockets layer (SSL). The first example shows you the factorySocketClient class not using SSL. The second example shows you the same class, renamed factorySSLSocketClient, using SSL.
