Using Java Secure Socket Extension 1.5

This information applies only to using JSSE on iSeries™ servers that run J2SDK, version 1.5 and subsequent releases. 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 native iSeries JSSE provider and an IBM pure Java JSSE provider. Also, Sun Microsystems, Inc. JSSE was initially shipped onSystem i™ and will continue to be shipped.

• Configuring your server to support JSSE 1.5
  Configure your System i5™ to use different JSSE implementations. This topic includes software requirements, how to change JSSE providers, and the necessary security properties and system properties. The default configuration uses the IBM pure Java JSSE provider known as IBMJSSE2.

• Using the native System i5 JSSE 1.5 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 1.5
  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.
