金典小程序之密码加密

此程序的要求是随机生成一个用户名和一个密码，存入txt文档中，然后取出来把密码加密后再次存储。主要练习python文件的操作。

import re
import random
import hashlib
charactor=\'abcdefghijklmnopqrstuvwxyz0123456789\'
len_char = len(charactor)-1
#生成名字
list=[]
count = 0
while count<4:
    for i in charactor[random.randint(0,len_char)]:
        list.append(i)
    count+=1
name = \'\'.join(list)
print(\'name\',name)

#生成密码
list_password=[]
count = 0
while count<6:
    for i in charactor[random.randint(0,len_char)]:
        list_password.append(i)
        count += 1
password = \'\'.join(list_password)
print(\'password\',password)
save = open(r\'C:\Users\jeep-peng zhang\Desktop\2.txt\',\'w\',encoding=\'gbk\')
save.write(name+\',\'+password+\'\n\')
save.close()
#加密
f = open(r\'C:\Users\jeep-peng zhang\Desktop\2.txt\',\'r\',encoding=\'gbk\')
password_hash= f.readline().strip().split(\',\')
password_hash[1]= password_hash[1].encode(\'gb2312\')#注意：hash要在unnicode编码前进行
hash_read = hashlib.md5(password_hash[1]).hexdigest()

f=open(r\'C:\Users\jeep-peng zhang\Desktop\md5.txt\',\'w\',encoding=\'gbk\')
f.write(password_hash[0]+\',\'+hash_read+\'\n\')
f.close()

while count<4:
    for i in charactor[random.randint(0,len_char)]:
        list.append(i)
    count+=1
name = \'\'.join(list)
print(\'name\',name)
此程序的作用是循环4次生成一个随机的4位数的用户名。
