python在线反编译

获得源码

import base64

def encode(message):
    s = ''
    for i in message:
        x = ord(i) ^ 32
        x = x + 16
        s += chr(x)

    return base64.b64encode(s)

correct = 'XlNkVmtUI1MgXWBZXCFeKY+AaXNt'
flag = ''
print 'Input flag:'
flag = raw_input()
if encode(flag) == correct:
    print 'correct'
else:
    print 'wrong'

对应着逆回去

import base64

def decode(str):
        s=base64.b64decode(str)
        flag=''
        for i in s:
                flag+=chr((ord(i)-16)^32)
        return flag

flag=decode('XlNkVmtUI1MgXWBZXCFeKY+AaXNt')
print flag
