- # Python简单密码加密程序
- # 随机生成4位salt，与原始密码组合，通过md5加密
- # Author : Lrg
- # -------------------------------------------
- # encoding = utf-8
- from random import Random
- from hashlib import md5
- # 获取由4位随机大小写字母、数字组成的salt值
- def create_salt(length = 4):
- salt = ''
- chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
- len_chars = len(chars) - 1
- random = Random()
- for i in xrange(length):
- # 每次从chars中随机取一位
- salt += chars[random.randint(0, len_chars)]
- return salt
- # 获取原始密码+salt的md5值
- def create_md5(pwd,salt):
- md5_obj = md5()
- md5_obj.update(pwd + salt)
- return md5_obj.hexdigest()
- # 原始密码
- pwd = '20141124'
- # 随机生成4位salt
- salt = create_salt()
- # 加密后的密码
- md5 = create_md5(pwd, salt)
- print '[pwd] ',pwd
- print '[salt] ', salt
- print '[md5] ', md5
效果如下（由于salt每次随机取，MD5当然也不一样）：
- [pwd]
- 20141124
- [salt]
- Ecm6
- [md5]
