Python生成MD5值的两种方法实例分析

# -*- coding:utf-8 -*-
import datetime
# NO.1 使用MD5
import md5
src = 'this is a md5 test.'
m1 = md5.new()
m1.update(src)
print m1.hexdigest()

# -*- coding:utf-8 -*-
# NO.2 使用hashlib
import hashlib
src = 'this is a md5 test.'
m2 = hashlib.md5()
m2.update(src)
print m2.hexdigest()

# -*- coding:utf-8 -*-
import md5
import time
now = 'file'+str(time.time())
print now,type(now)
m0 = md5.new()
m0.update(now)
print m0.hexdigest()
