Hi, I'm encountering an error when trying to connect to the RDP proxy:

The real host is Windows Server 2012 R2
I am using Python 3.4.5.
I was able to work around this by changing the various lines in parsing.py that had the following:
regex = b".*%s0002000000" % hexlify(b"NTLMSSP")
replace the % symbol with +
Your change breaks things. I would not expect the program to work properly.
Looks like you need at least Python 3.5 to use Seth.
