30 Apr 2002 This tutorial explains the use of the Java™ Secure Socket Extension (JSSE) packages included in JDK 1.4. The complexity of using JSSE is not in the communication itself, but rather in the configuration. Before you can run your client/server software, you must create the keys needed by the encryption algorithms, and these keys must be properly loaded by your software before it can create secure sockets. This tutorial provides cookbook-style instructions for creating and installing JSSE encryption keys in a client/server application environment.
Prerequisites
To follow the discussion in this tutorial, you need to know a few things about the Java language, starting with the basics of Java programming in a client/server environment (that is, working with classes, objects, threads, and so on). Because stream and socket communication is central to the discussion, you need to know how to use streams and sockets. In particular, you should know what a stream is and what it is used for. You should know how to create a Socket and a ServerSocket, how to get streams from each, and how to communicate using those streams. You also should know how to create and compile a .java file using the JDK or an IDE. You do not need to know anything about encryption technology to complete this tutorial. You will be given the information you need to create secure client/server connections within your applications.
System requirements
You will need JavaScript enabled on your browser. To run the examples in this tutorial, you need the following tools and components:
- JDK 1.4 from Sun Microsystems
- A development environment -- either an IDE or a suitable command-shell
- A computer on which you can run an Internet server
