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()
7 self.init_window.title('MD5转换工具')
8 self.init_window.geometry('1068x681+10+10')
9 def run(self):
10 self.left_lable = tkinter.Label(self.init_window,text='原始数据')
11 self.left_lable.grid(row=0,column=0)

26 self.init_window.mainloop()
27 def changetomd5(self):
28 source = self.source_text.get(1.0,tkinter.END).strip().replace("\n","").encode()
29 changemd5 = hashlib.md5()
30 changemd5.update(source)
31 ret = changemd5.hexdigest()
32 self.insert(ret)
33 def strtobase64(self):

36 self.insert(change_base64)

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
