Topic: How to add custom Client Handshake Extension with only JNI
I am wondering if it is possible to add a custom Client Handshake Extension to tls1.3 connections using Java code only and what steps would be required. If not when what steps would need to be taken to add it into the JNI. Doing this because I have a custom Openssl server and trying to put this on Android so I would like a easy way add a extension without rebuilding a whole TLS1.3 stack
