How to implement TLS 1.3 in Java Spring boot Application?

Question

I want to implement TLS 1.3 in my spring boot application.

https://blog.gypsyengineer.com/en/security/an-example-of-tls-13-client-and-server-on-java.html

In this blog i have seen that TLS 1.3 can be used only with Java 11.. is that true?

Please give me step by step proceduce to implement it.

Answer 1

If you want just TLSv1.3 in your Spring Boot application, you can configure this in your application.properties file (or any properties/yml file that is part of an active profile).

server.ssl.enabled-protocols=TLSv1.3

The server.ssl.enabled-protocols property takes a list, so if you want TLSv1.2 and TLSv1.3, you can do that as well:

server.ssl.enabled-protocols=TLSv1.2,TLSv1.3

A comprehensive guide to configuring SSL/TLS in Spring Boot can be found here , in the documentation. All of the SSL/TLS properties can be found in this appendix in the documentation.

And to answer your question, yes, TLSv1.3 was delivered in Java 11.
