Python计算checksum

很简单，不多说了, 记下来备忘。看代码：

# 假设有2个二进制文件（0.bin, 1.bin)，用checksum检验内容是否相同

# coding: utf8

# Python2.6.2
import md5

with open('0.bin', 'rb') as f:
    s = md5.new(f.read()).hexdigest()

with open('1.bin', 'rb') as f:
    ss = md5.new(f.read()).hexdigest()

print repr(s), len(s)
print repr(ss), len(ss)

 

输出内容如下：
'cf7bcb6e663f0ca8a3e6f200b26ed95a' 32
'cf7bcb6e663f0ca8a3e6f200b26ed95a' 32

md5 is Deprecated since release 2.5
so use hashlib instead.

#coding:gbk

import hashlib
m = hashlib.md5()

m.update("AAA")
print m.hexdigest()

m.update("BBB")
print m.hexdigest()

多谢提醒！
