常用的消息摘要算法有MD5和SHA，这些算法在python和go的库中都有，需要时候调用下就OK了，这里总结下python和go的实现。

一、python消息摘要示例

代码如下：

复制代码 代码如下:

! /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",funcMapfuncName

运行效果：

二、go语言消息摘要示例

代码如下：

复制代码 代码如下:

/
File : hashTest.go
Author : Mike

/
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,funcMapfuncName.Sum())
}
}
