Python DES 加密解密，就是大家所谓想要的那个非常快速的方法
这个要借助Crypto.Cipher这个插件来实现的，引用后只需要写如下代码即可1 from Crypto.Cipher import DES
2
3 class MyDESCrypt:
4
5 key = chr(11)+chr(11)+chr(11)+chr(11)+chr(11)+chr(11)+chr(11)+chr(11)
6 iv = chr(22)+chr(22)+chr(22)+chr(22)+chr(22)+chr(22)+chr(22)+chr(22)
7
8 def __init__(self,key='',iv=''):
9 if len(key)> 0:
10 self.key = key
11 if len(iv)>0 :
12 self.iv = iv
13
14 def ecrypt(self,ecryptText):
15 try:
16 cipherX = DES.new(self.key, DES.MODE_CBC, self.iv)
17 pad = 8 - len(ecryptText) % 8
18 padStr = ""
19 for i in range(pad):
20 padStr = padStr + chr(pad)
21 ecryptText = ecryptText + padStr
22 x = cipherX.encrypt(ecryptText)
23 return x.encode('hex_codec').upper()
24 except:
25 return ""
26
27
28 def decrypt(self,decryptText):
29 try:
30
31 cipherX = DES.new(self.key, DES.MODE_CBC, self.iv)
32 str = decryptText.decode('hex_codec')
33 y = cipherX.decrypt(str)
34 return y)*-1]
35 except:
36 return ""
