When developing an application that needs to communicate securely with another device TLS is a great option. The framework in place for TLS connections with JAVA is JSSE (Java Secure Socket Extension). JSSE is a set of interfaces that can be called to abstract the TLS process and make it easy for plugging in different security providers while keeping an application unchanged after initial integration. wolfJSSE is an open source implementation of these interfaces that uses the embedded IoT wolfSSL library for it’s cryptography operations. There are many ways to interact with JSSE when adding in security, two of the common ways are with creating a SSL socket or by creating a SSL engine. A simple example of creating and using SSL sockets for both the client and server side can be found in the “examples/provider” directory on the wolfssljni repository located here (https://github.com/wolfSSL/wolfssljni). In addition to interacting with JSSE directly there are packages in JAVA that use it. One such package deals with URL connections and can be used for creating HTTPS connections. An example of a simple HTTPS connection using it can be found in the “java” directory of the wolfSSL examples repository (https://github.com/wolfSSL/wolfssl-examples).
