The non-free editions of VNC offer session encryption.
If the data in my VNC session isn't all that confidential, do I really need
session encryption?
For example, suppose someone intercepts/hijacks/whatever my VNC session.
Clearly, any password I type during the session would thus be available to
the attacker in cleartext. But suppose I don't do that, and there's nothing
in the datastream in the VNC session that's proprietary, confidential, etc.
Could the attacker use the hijacked VNC session to gain access to the host
I've connected to? (Viz, the host that the VNC server is running on.)
Finally, how expensive is encryption (and decryption) in terms of CPU?
Best,
SJF
