常用的消息摘要算法有MD5和SHA，這些算法在python和go的庫中都有，需要時候調用下就OK了，這里總結下python和go的實現。

一、python消息摘要示例

代碼如下：

#! /usr/bin/python
'''
      File      : testHash.py
      Author    : Mike
      E-Mail    : Mike_Zhang@live.com
'''
import hashlib
src = raw_input("Input string : ")
funcNameList = ["MD5","SHA1","SHA224","SHA256","SHA384","SHA512"]
funcMap = {
"MD5"            :      lambda cnt : hashlib.md5(cnt).hexdigest(),
"SHA1"           :      lambda cnt : hashlib.sha1(cnt).hexdigest(),
"SHA224"         :      lambda cnt : hashlib.sha224(cnt).hexdigest(),
"SHA256"         :      lambda cnt : hashlib.sha256(cnt).hexdigest(),
"SHA384"         :      lambda cnt : hashlib.sha384(cnt).hexdigest(),
"SHA512"         :      lambda cnt : hashlib.sha512(cnt).hexdigest()
}
for funcName in funcNameList :
        print funcName,"/t:/t",funcMap[funcName](src)

運行效果：

二、go語言消息摘要示例

代碼如下：

復制代碼代碼如下:

/*
      File      : hashTest.go
      Author    : Mike
      E-Mail    : Mike_Zhang@live.com
*/
package main

import (
        "fmt"
        "crypto/md5"
        "crypto/sha1"
        "crypto/sha256"
        "crypto/sha512"
        "hash"
)

func main() {
        funcNameList := []string{"MD5","SHA1","SHA224","SHA256","SHA384","SHA512"}
        funcMap := map[string]func(msg []byte) hash.Hash{
        "MD5"           :   func(msg []byte) hash.Hash{var h hash.Hash = md5.New();h.Write(msg);return h},
        "SHA1"          :   func(msg []byte) hash.Hash{var h hash.Hash = sha1.New();h.Write(msg);return h},
        "SHA224"        :   func(msg []byte) hash.Hash{var h hash.Hash = sha256.New224();h.Write(msg);return h},
        "SHA256"        :   func(msg []byte) hash.Hash{var h hash.Hash = sha256.New();h.Write(msg);return h},
        "SHA384"        :   func(msg []byte) hash.Hash{var h hash.Hash = sha512.New384();h.Write(msg);return h},
        "SHA512"        :   func(msg []byte) hash.Hash{var h hash.Hash = sha512.New();h.Write(msg);return h},
        }
        fmt.Printf("Input string : ")
        var msg1 string
        fmt.Scanf("%s",&msg1)
        for _,funcName := range funcNameList{
                fmt.Printf("%s /t:/t %x/n",funcName,funcMap[funcName]([]byte(msg1)).Sum())
        }
}
