pyc文件，用在线转换或者uncompyle6转换成py文件

这里有个问题，如果这个加密是变形加密，就要用手脱了。找个时间学一下

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 = input()
if encode(flag) == correct:
    print ('correct')
else:
    print ('wrong')

逻辑很简单
