unsupported operand type(s) for &: 'str' and 'int'

Hi!
I've tried to run example from the README file, but it fails with the following:

  File "../lib/python3.6/site-packages/twisted/python/log.py", line 103, in callWithLogger
    return callWithContext({"system": lp}, func, *args, **kw)

Are you going to support the library furthermore?

I'll check this out. Sorry for the delay.

Could you paste me a bit of code of your example @alex2304 ?
pref the function at: File "../recognition/pyVNC/rfb.py", line 494, i

In my case, I solved it by adding following line at line 429 in pyDes.py:
ch = ch if isinstance(ch, int) else ord(ch)
ch sometimes is an int and sometimes is a str, with this instruction you correctly cast it for the logical operation in the next line.
