golang：MD5的几种实现方式

package main

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

func main() {
	{
		h := crypto.MD5.New()
		io.WriteString(h, "test1280")
		fmt.Printf("%x\n", h.Sum(nil))
	}

	{
		h := md5.New()
		io.WriteString(h, "test1280")
		fmt.Printf("%x\n", h.Sum(nil))
	}

	{
		data := []byte("test1280")
		fmt.Printf("%x\n", md5.Sum(data))
	}
}

运行：

C:\Users\test1280\Desktop\test1280>go run main.go
