('binary' encoding is not supported, stored as-is) I sniffed an unencrypted VNC session between my test machines. I noticed that a challenge (\337n\304KG\311\021\302\344\246\333i\375\324\316\341) sent from the server and the response (h\374\215d\306\207B\n^\243d]\222(j\242) from the client. I know the password because it was set by me but I was wondering what format the challenge/response is in and how to reverse it?
