java netty（客户端/服务器）设置中的 TLS 服务器和普通 TCP 客户端（通过本地 LAN）

Question

I have a peer to peer (Client/Server) setup (over local LAN) , this is using Netty ,a java networking framework. I use raw TCP /IP (as in, no HTTP) for communication and transfers. Now as per requirement we want to shift on TLS communication.

(client using TLS) <-----> (TLS server) it works

(simple tcp client) <-----> (TLS server) doesn't work

Please let me know how it will work

Basically all you need to do is to add the SslHandler to the pipeline of both and configure it with the correct keys / certs.

Something like:

SslContextBuilder builder = ...;
SslContext ctx = builder.build();
pipeline.addLast(ctx.newHandler(channel.alloc()));
