# coding:utf-8
import os
import sys
key = [0xAC, 0xEC, 0xDF, 0x57]
def crack_file(argv):
filename = argv[0]
new_name = argv[1]
file = open(filename, "rb")
file.seek(1024, os.SEEK_SET) # 偏移量1024
changed_file = open(new_name, 'wb+') # 以二进制追加写的方式打开
try:
b = file.read(4) # 一次读4个字节 type(b) --> 'bytes'
while(b):
for num,i in enumerate(b):
h = i >> 4 # type(i) --> int
l = i & 0xf
kh = key[num] >> 4
kl = key[num] & 0xf
y = l ^ kl
y = (h ^ kh ^ y) |
