TLS encrypted transmission

The TLS encrypted transmission of dubbo-go is realized by dubbo-getty(https://github.com/apache/dubbo-getty). Before using TLS, you need to be prepared as follows.

• CA certificate file
• Key files & certificate files of client and server

You can use the sample files in certs folder.

├── certs
│   ├── ca.key
│   ├── ca.pem
│   ├── client.key
│   ├── client.pem
│   ├── server.key
│   └── server.pem

Server side

Can be run inconfig.Load to import configuration before .

func init(){
  //Certificate
  serverPemPath, _ := filepath.Abs ("../certs/ server.pem ")
  //Private key
  serverKeyPath, _ := filepath.Abs ("../certs/ server.key ")
  //CA certificate
  caPemPath, _ := filepath.Abs ("../certs/ ca.pem ")
  //Turn on TLS
  config.SetSslEnabled (true)
  //Import TLS configuration
  config.SetServerTlsConfigBuilder (& getty.ServerTlsConfigBuilder {
    ServerKeyCertChainPath:        serverPemPath,
    ServerPrivateKeyPath:          serverKeyPath,
    ServerTrustCertCollectionPath: caPemPath,
  })
}

Client side

The setting of the client side is similar to that of the server side, and there is no need to set the certificate

func init(){
//Private key
	clientKeyPath, _ := filepath.Abs ("../certs/ ca.key ")
//CA certificate
	caPemPath, _ := filepath.Abs ("../certs/ ca.pem ")
//Turn on TLS
	config.SetSslEnabled (true)
//Import TLS configuration
  config.SetClientTlsConfigBuilder (& getty.ClientTlsConfigBuilder {
    ClientPrivateKeyPath:          clientKeyPath,
		ClientTrustCertCollectionPath: caPemPath,
  })
}

Other settings are consistent with HelloWorld(https://github.com/apache/dubbo-go-samples/tree/master/helloworld).
