Using Java Secure Socket Extension

This information applies only to using JSSE on system that run Java™ 2 Platform, Standard Edition (J2SE) 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 IBM i JSSE provider and an IBM pure Java JSSE provider.
