windows 文件hash校验，字符串加密，base64转换工具

对下载的文件使用hash校验验证文件完整性

 1 import hashlib
 2 def md5():
 3     md5_value = hashlib.md5()
 4     with open('C:\Intel\S6720HI-V200R019C10SPC500.cc','rb') as f:
 5         while True:
 6             data = f.read(2048)
 7             if not data:
 8                 break
 9             md5_value.update(data)
10     print (md5_value.hexdigest())
11 md5()

也可用于前端页面注册用户信息，加密发送给后端

 1 import hashlib
 2 #创建对象，加盐
 3 has = hashlib.md5('奔波的驱魔人'.encode('utf-8'))
 4 pwd = input('请输入密码>>>')
 5 #传入需要加密的字段
 6 has.update(pwd.encode('utf-8'))
 7 print(has.hexdigest())
 8
 9 #以上代码md5值等同于以下
10 has = hashlib.md5()
11 pwd = input('请输入密码>>>')
12 #传入需要加密的字段
13 has.update('奔波的驱魔人'.encode('utf-8'))
14 has.update(pwd.encode('utf-8'))
15 print(has.hexdigest())

base64编码与解码

1 import base64
2 a = 'vx:cs19911124'
3 a_encode = base64.b64encode(a.encode('utf-8'))
4 print(a_encode.decode('utf-8'))
5 b_decode = base64.b64decode(a_encode).decode('utf-8')
6 print(b_decode)

封装进 tkinter

 1 import tkinter
 2 from tkinter import filedialog
 3 import hashlib,base64
 4 class dark:
 5     def __init__(self):
 6         self.init_window = tkinter.Tk()

11         self.left_lable.grid(row=0,column=0)

29         changemd5 = hashlib.md5()
30         changemd5.update(source)
31         ret = changemd5.hexdigest()
32         self.insert(ret)
33     def strtobase64(self):
34         source = self.source_text.get(1.0,tkinter.END).strip().replace("\n","").encode()
35         change_base64 = base64.b64encode(source).decode()

39         change_base64 = base64.b64decode(source).decode()
40         self.insert(change_base64)
41     def filetomd5(self):
42         selectFile = filedialog.askopenfilename()
43         md5_value = hashlib.md5()
44         try:
45             with open(selectFile,'rb') as f:
46                 while True:
47                     data = f.read(2048)
48                     if not data:
49                         break
50                     md5_value.update(data)
51             self.insert(md5_value.hexdigest())
52         except:
53             pass
54     def insert(self,data):
55         self.change_text.delete(1.0,tkinter.END)
56         self.change_text.insert(1.0,data)
57 obj = dark()
58 obj.run()

打包成exe程序，运行效果如下
