本文实例讲述了golang简单tls协议用法。，具体如下：
生成私钥：
openssl genrsa -out key.pem 2048
生成证书：
openssl req -new -x509 -key key.pem -out cert.pem -days 3650
https：
package main
import (
"io"
"net/http"
"log"
)
func HelloServer(w http.ResponseWriter, req *http.Request) {
io.WriteString(w, "hello, world!n")
}
func main() {
http.HandleFunc("/hello", HelloServer)
err := http.ListenAndServeTLS(":8080", "cert.pem", "key.pem", nil)
if err != nil {
log.Fatal("ListenAndServe: ", err)
}
}
提示: 访问请勿忘记使用https开头,否则chrome会下载一个文件如下:
dotcoo-air:tls dotcoo$ cat /Users/dotcoo/Downloads/hello | xxd
0000000: 1503 0100 0202 0a .......
TLS Server：
package main
import (
"log"
"crypto/tls"
"net"
"bufio"
)
func main() {
log.SetFlags(log.Lshortfile)
cer, err := tls.LoadX509KeyPair("cert.pem", "key.pem")
if err != nil {
log.Println(err)
return
}
config := &tls.Config{Certificates: []tls.Certificate{cer}}
ln, err := tls.Listen("tcp", ":8000", config)
if err != nil {
log.Println(err)
return
}
defer ln.Close()
for {
conn, err := ln.Accept()
if err != nil {
log.Println(err)
continue
}
go handleConnection(conn)
}
}
func handleConnection(conn net.Conn) {
defer conn.Close()
r := bufio.NewReader(conn)
for {
msg, err := r.ReadString('n')
if err != nil {
