Using Java Secure Socket Extension 1.4

This information applies only to using JSSE on a System i5™ that runs J2SDK, version 1.4. JSSE is like a framework that abstracts the underlying mechanisms of both SSL and TLS. By abstracting the complexity and peculiarities of the underlying protocols, JSSE enables programmers to use secure, encrypted communications while at the same time minimizing possible security vulnerabilities. Java™ Secure Socket Extension (JSSE) uses both the Secure Sockets Layer (SSL) protocol and the Transport Layer Security (TLS) protocol to provide secure, encrypted communications between your clients and servers.

The IBM^® implementation of JSSE is called IBM JSSE. IBM JSSE includes a nativeSystem i5 JSSE provider and a pure Java JSSE provider.

• Configuring your system to support JSSE 1.4
  Configure your system to use IBM JSSE. This topic includes software requirements, how to change JSSE providers, and the necessary security properties and system properties.

• Using the native System i5 JSSE 1.4 provider
  The native System i5 JSSE provider offers the full suite of JSSE classes and interfaces including implementations of the JSSE KeyStore class and the SSLConfiguration class.

• Examples: IBM Java Secure Sockets Extension 1.4
  The JSSE examples show how a client and a server can use the native System i5 JSSE provider to create a context that enables secure communications.
