hanahmily commented on issue #4470: Enable OAP gRPC SSL transportation URL: https://github.com/apache/skywalking/pull/4470#issuecomment-596585337 > 1. Only `ReceiverGRPCHandlerRegister` should support only server-side receiver. You could read the codes, only it has the `#addFilter` for `AuthenticationInterceptor`. Don't get your point.`ReceiverGRPCHandlerRegister` intends to add `interceptor` or `service` to `NettyServerBuilder` by invoking its `addService` method. But SSL should invoke `NettyServerBuilder#sslContext`. I don't find any link between them. Do I miss something? feel free to correct me. > 2. If we talk about the core module, you have to implement the client side TLS inside `GRPCRemoteClient`, in oder to make sure it matches the core configuration. And this TLS should be used for internal only. make sense. I should enable client ssl at the same time. There's also a scenario for `sharing-server`, if we want to enable external SSL and disable internal SSL, client ssl needs to read config from `sharing-server` instead of `core`, right?
