problem description
how to use byte array decryption in Python when getting java des encrypted data and key,?
the environmental background of the problems and what methods you have tried
when performing python automated testing, you need to decrypt and compare the data

print ("Example of DES encryption using CBC mode\n")
key = [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
arr = bytearray(key)
k = triple_des(key, CBC, pad=None, padmode=PAD_PKCS5)
data = "DES encryption algorithm"
print ("Key : %r" % k.getKey())
print ("Data : %r" % data)
d = k.encrypt(data)
print ("Encrypted: %r" % d)
if _ _ name__=="__main__":
ss = desDescrypt()
print ss
what result do you expect? What is the error message actually seen?
