istio和主进程之间的通信是否在istio中加密了?

我知道istio支持mTLS以便通过istio代理进行服务间通信，但是我在其官方站点上找不到任何文档来解释istio代理容器与ampio之间的通信状态.主容器本身是否位于吊舱中? (假设它是一个Kubernetes托管集群)

I know that istio supports mTLS for inter-service communication done through istio proxy but I couldn't find any documentation on their official site explaining the state of traffic between istio proxy container & main container itself in a pod ? (assuming it's a kubernetes managed cluster)

代理服务器和主容器之间的通信是否已加密?如果不是默认情况，是否有任何配置或插件可以启用此行为?

Is the traffic encrypted between proxy and main containers ? If it's not by default, is there any config or plugin out there that can enable this behaviour ?

对此表示感谢.
