golang中md5生成

package main

import (
	"crypto/md5"
	"fmt"
	"io"
)

// golang md5加密
func main()  {
	h := md5.New()
	// 签名
	sign := "wasdhasdhjasduh"

	// 生成md5码写法1
	io.WriteString(h, sign)
	sum := fmt.Sprintf("%x", h.Sum(nil))
	fmt.Println("sum:", sum)


	// 生成md5码写法2
	data := []byte("wasdhasdhjasduh")
	sum = fmt.Sprintf("%x\n", md5.Sum(data))
	fmt.Println("sum:", sum)

	//sum: f4879827716b8ce02a04708ba09a04a6
	//sum: f4879827716b8ce02a04708ba09a04a6
