JSSE stands for Java Secure Socket Extension. It is a Java implementation of Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. Its functionality includes data encryption, server authentication, message integrity, and optional client authentication.

It is so named because originally it was shipped as a separate extension to Java 1.2 and 1.3. Since Java 1.4 it has been part of the standard Java API.

This tag should be used for questions about TLS or SSL programming in Java.
