Python DES encryption and decryption is what we call the very fast method, pythondes

This is implemented using the Crypto. Cipher plug-in. After referencing it, you only need to write the following code:

 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 = key11         if len(iv)>0 :12             self.iv = iv13         14     def ecrypt(self,ecryptText):15        try:16            cipherX = DES.new(self.key, DES.MODE_CBC, self.iv)17            pad = 8 - len(ecryptText) % 818            padStr = ""19            for i in range(pad):20               padStr = padStr + chr(pad)21            ecryptText = ecryptText + padStr22            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[0:ord(y[len(y)-1])*-1]35         except:36             return ""
