go get github.com/Yee2/shadowsocks-goshadowsocks-go provides a Go version implementation of the shadowsocks protocol, supporting AEAD encryption and Stream encryption. The main working principle is to encode a pipe for plaintext transmission, and data written to the pipe will be automatically encrypted, while data read from the pipe will be automatically decrypted.
package main
import (
"bytes"
"github.com/Yee2/shadowsocks-go"
"log"
)
func main() {
buf := new(bytes.Buffer)
// Create a shadowsocks configuration
tunnel, err := shadowsocks.NewTunnel("aes-256-gcm", "12345678")
checkErr(err)
// shadow the channel
shaded, err := tunnel.Shadow(&shadowsocks.Closeable{ReadWriter: buf})
checkErr(err)
// Close channel will free some reusable resources like bytes buffer etc
defer shaded.Close()
// Write data is automatically encrypted and read data is automatically decrypted
_, err = shaded.Write([]byte("hello shadowsocks!"))
checkErr(err)
var data [32]byte
n, err := shaded.Read(data[:])
checkErr(err)
log.Printf("%s\n", data[:n])
}
func checkErr(err error) {
if err != nil {
log.Fatalln(err)
}
}
