In this article, we discuss how to easily configure an SSL/TLS connection in Java to better secure your application.

Setting up encryption for your application, how hard can it be? I thought it would be easy, after all, all communication with modern web applications should be encrypted, right? Well, my expectations were wrong. While setting it up, I encountered a couple of hidden difficulties. For example, the configuration is vague, verbose, not straight-forward to set it up, hard to debug, and not unit-test friendly.

For this article, I’ll assume you already have a basic understanding of certificates, keystores, encryption protocols, and ssl-handshake. If not, I would recommend going through this article: How to Easily Set Up Mutual TLS.

It will go through the following topics:

• No security.
• One-way authentication.
• Two-way authentication.
• Two-way authentication with trusting the Certificate Authority.

I will also explain how to create KeyStores, Certificates, Certificate Signing Requests, and how to implement these techniques.
