[go-nuts] [urgent] the right way of using Blowfish decryption?

[Jason Wang]

I have a python function: 

import from Crypto.Cipher import Blowfish
import binascii

def decrypt_password(encode):
     key = 'aa11k55544332211aabbaabbaaddccbb'
     blowfish = Blowfish.new(key, Blowfish.MODE_ECB)
     packed_password = blowfish.decrypt(binascii.unhexlify(encode))
     return packed_password

My Golang code is like:

func DecodePassword(pwd string) (decoded string, err error) {
h, err := hex.DecodeString(pwd)
if err != nil {
return
}
var dst = make([]byte, len(h))
cipher, err := blowfish.NewCipher([]byte(blowfishKey))
if err != nil {
return
}
cipher.Decrypt(dst, h)
decoded = string(dst)
return
}

the result of Python is like "Vmt7?m3My\x07\x07\x07\x07\x07\x07\x07" , the 
first 9 bytes is useful.
the result of Go is like "Vmt7?m3M\x00\x00\x00\x00\x00\x00\x00\x00", the 
first 8 bytes is right, the rest 8 bytes is wrong.

Is the "Blowfish.MODE_ECB" parameter in python the key point?
How should blowfish be correctly used?
