+# Use TLS encryption in Dubbo go
+
+## Usage
+
+0. Generate the required certificate and secret key
+
+This example provides the generated certificate and secret key under the directory `tls/x509`
+
+1. Configure dubbogo.yaml
+
+Client TLS configuration:
+
+```yaml
+dubbo:
+   tls_config:
+      ca-cert-file: ../../../x509/server_ca_cert.pem
+      tls-cert-file: ../../../x509/client2_cert.pem
+      tls-key-file: ../../../x509/client2_key.pem
+      tls-server-name: dubbogo.test.example.com
+```
+
+Server TLS configuration:
+
+```yaml
+dubbo:
+   tls_config:
+      ca-cert-file: ../../../x509/client_ca_cert.pem
+      tls-cert-file: ../../../x509/server2_cert.pem
+      tls-key-file: ../../../x509/server2_key.pem
+      tls-server-name: dubbogo.test.example.com
+```
+
+2. Startup example
+
+This example provides TLS encryption examples of Dubbo, Grpc and Triple communication modes, respectively located in
+
+`tls/dubbo` 、`tls/grpc` 、`tls/triple`。 Enter the folder to launch the sample.
+
+Take tls/dubbo as an example:
+
+Start the server:
+
+Enter 'tls/dubbo/go server/cmd' and start 'server.go`
+
+The TLS configuration takes effect when you see the following logs
+
+```
+2022-12-01T23:39:30.690+0800 INFO getty/getty_ server. go:78 Getty Server initialized the TLSConfig configuration
+```
+
+Start client:
+
+Enter 'tls/dubbo/go client/cmd' and start 'client.go`
+
+The TLS configuration takes effect when you see the following logs
+
+```
+2022-12-01T23:40:05.998+0800 INFO grpc/client. go:90 Grpc Client initialized the TLSConfig configuration
+```

+# 在Dubbo-go中使用TLS加密
+
+## 使用方法
+0.生成所需要的证书和秘钥
+本示例提供已经生成好的证书和秘钥，在目录`tls/x509`下
+
+1.配置dubbogo.yaml
+
+客户端TLS配置：
+
+```yaml
+dubbo:
+  tls_config:
+    ca-cert-file: ../../../x509/server_ca_cert.pem
+    tls-cert-file: ../../../x509/client2_cert.pem
+    tls-key-file: ../../../x509/client2_key.pem
+    tls-server-name: dubbogo.test.example.com
+```
+
+服务端TLS配置：
+
+```yaml
+dubbo:
+  tls_config:
+    ca-cert-file: ../../../x509/client_ca_cert.pem
+    tls-cert-file: ../../../x509/server2_cert.pem
+    tls-key-file: ../../../x509/server2_key.pem
+    tls-server-name: dubbogo.test.example.com
+```
+2. 启动示例 
+
+本示例提供了Dubbo、Grpc、Triple三种通信方式的TLS加密示例，分别位于`tls/dubbo` 、`tls/grpc` 、`tls/triple`。进入文件夹即可启动示例。
+
+以tls/dubbo为例: 
+
+启动服务端：
+
+进入`tls/dubbo/go-server/cmd`,启动`server.go`
+
+看到如下日志，则TLS配置生效
+
+```
+2022-12-01T23:39:30.690+0800    INFO    getty/getty_server.go:78        Getty Server initialized the TLSConfig configuration
+```
+
+启动客户端：
+
+进入`tls/dubbo/go-client/cmd`，启动`client.go`
+
+看到如下日志，则TLS配置生效
+
+```
+2022-12-01T23:40:05.998+0800    INFO    grpc/client.go:90       Grpc Client initialized the TLSConfig configuration
+```
