  • 简单的密码管理器(Python)(待完善)

    需要使用的库：pymssql(用于连接SQL Server), PyQt5(用于窗口的制作)

    首先编写DOS界面的密码生成器，以及将程序与数据库相连接，用于存储和查询

    PasswordDOS.py

     1 from random import randint
 2 import pymssql
 3 
 4 
 5 def connect_to_sql():
 6     print('连接中...')
 7     connect = pymssql.connect('(local)', 'sa', '123456789', 'Password')
 8     if connect:
 9         print('连接成功...')
10     else:
11         print('未连接')
12         exit()
13     return connect
14 
15 
16 def rand_password():
17     whole_char = r'abcdefghijklmnopqrstuvwxyzABCDEFJHIJKLMNOPQRSTUVWXYZ._!@#$%^&*'
18     char_number = len(whole_char)
19     password_length = input('please input password lenght: ')
20     password = []
21     for _ in range(0, int(password_length)):
22         password.append(whole_char[randint(0, char_number - 1)])
23     return password
24 
25 
26 def inquiry_password(cursor):
27     name = input('please input password for use: ')
28     if name == '':
29         sql = r"select * from password"
30     else:
31         sql = r"select * from password where id ='" + name + "'"
32     cursor.execute(sql)
33     result = cursor.fetchall()
34     if len(result) == 0:
35         print('不存在该密码')
36     else:
37         for value in result:
38             print(value[0]+'的密码是：'+value[1])
39 
40 
41 def add_password(connect, cursor):
42     name = input('please input password for use: ')
43     pwd = input('please input password: ')
44     if pwd == '':
45         pwd = ''.join(rand_password())
46     sql = r"insert into password values('" + name + "', '" + pwd + "')"
47     cursor.execute(sql)
48     connect.commit()
49     print(name + '的密码是：' + pwd)
50 
51 
52 def delete_password(connect, cursor):
53     name = input('please input password for use: ')
54     sql = r"delete from password where id='" + name + "'"
55     cursor.execute(sql)
56     connect.commit()
57 
58 
59 def change_password(connect, cursor):
60     name = input('please input password for use: ')
61     pwd = input('please input password: ')
62     if pwd == '':
63         pwd = ''.join(rand_password())
64     sql = r"update password set pwd='" + pwd + "'where id='" + name + "'"
65     cursor.execute(sql)
66     connect.commit()
67     print(name + '的密码是：' + pwd)
68 
69 
70 def run():
71     connect = connect_to_sql()
72     cursor = connect.cursor()
73     while True:
74         flag = input('please input (A/D/C/I/E{add,delete,change,inquiry,exit}): ')
75         if flag == 'A' or flag == 'a':
76             add_password(connect, cursor)
77         elif flag == 'D' or flag == 'd':
78             delete_password(connect, cursor)
79         elif flag == 'C' or flag == 'c':
80             change_password(connect, cursor)
81         elif flag == 'I' or flag == 'i':
82             inquiry_password(cursor)
83         elif flag == 'E' or flag == 'e':
84             break
85     connect.close()
86 
87 
88 if __name__ == '__main__':
89     run()

    将DOS界面的程序进行稍微修改，用于窗口界面的导入文件

    password.py

      1 from random import randint
  2 import pymssql
  3 
  4 
  5 def connect_to_sql():

 10     else:
 11         print('未连接')
 12         exit()
 13     return connect

 20     password = []
 21     for _ in range(0, int(password_length)):

 27     # name = input('please input password for use: ')
 28     if name == 'all' or name == 'ALL':
 29         sql = r"select * from password"
 30     elif name == '':
 31         return '请输入账号'
 32     else:

 34     cursor.execute(sql)
 35     result = cursor.fetchall()
 36     if len(result) == 0:
 37         # print('不存在该密码')
 38         return '不存在该密码'
 39     else:

 43             _ += value[0]+'的密码是：'+value[1]+'
'
 44         return _
 45 
 46 
 47 def add_password(connect, cursor, name, pwd, length=16):
 48     # name = input('please input password for use: ')

 56             return '密码已存在，请使用修改'
 57     sql = r"insert into password values('" + name + "', '" + pwd + "')"
 58     cursor.execute(sql)
 59     connect.commit()

    使用PyQt5库编写窗口程序

120         print('退出成功')
121 
122 
123 if __name__ == '__main__':
124     run()

    暂时可以实现密码的生成、存储、修改、查询、删除的功能。
