How to use Azul's JSSE with TLS 1.3 support

https://github.com/openjsse/openjsse

"The OpenJSSE project was created to add support for TLS 1.3 to existing Java 8 applications without requiring code changes"

How to use this project exactly?

I'm currently using the AdoptOpenJDK build for Java 8.

Solution

  • As mentioned in the issue log for openjdk (Link):

    OpenJSSE for OpenJDK can be installed in two possible ways:

    • add OpenJSSE provider in the list of security providers of java.security file
    • registered at runtime with Security.insertProviderAt method

    However you'll better use Azul JDK8 builds as soon as it has preintegrated and fully tested support for OpenJSSE provider with -XX:+UseOpenJSSE
