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

 from Crypto.Cipher import DES

 class MyDESCrypt:

     key = chr(11)+chr(11)+chr(11)+chr(11)+chr(11)+chr(11)+chr(11)+chr(11)
     iv = chr(22)+chr(22)+chr(22)+chr(22)+chr(22)+chr(22)+chr(22)+chr(22)

     def __init__(self,key='',iv=''):
         if len(key)> 0:
             self.key = key
         if len(iv)>0 :
             self.iv = iv

     def ecrypt(self,ecryptText):
        try:
            cipherX = DES.new(self.key, DES.MODE_CBC, self.iv)
            pad = 8 - len(ecryptText) % 8
            padStr = ""
            for i in range(pad):
               padStr = padStr + chr(pad)
            ecryptText = ecryptText + padStr
            x = cipherX.encrypt(ecryptText)
            return x.encode('hex_codec').upper()
        except:
            return ""

     def decrypt(self,decryptText):
         try:

             cipherX = DES.new(self.key, DES.MODE_CBC, self.iv)
             str = decryptText.decode('hex_codec')
             y = cipherX.decrypt(str)
             return y[0:ord(y[len(y)-1])*-1]
         except:
             return ""
