In the meantime, if you need real security, we recommend installing an SSH server and using SSH tunneling for all TightVNC connections from untrusted networks. To solve this problem, we have plans to implement built-in encryption in future versions of TightVNC. So using TightVNC over the Internet can be a security risk. TightVNC: Installation Instructions (Windows)įrequently Asked Questions Q: How Secure is TightVNC?Ī: Although TightVNC encrypts VNC passwords sent over the net, the rest of the traffic is sent as is, unencrypted (for password encryption, VNC uses a DES-encrypted challenge-response scheme, where the password is limited by 8 characters, and the effective DES key length is 56 bits). System Requirements: Supports all client and server versions of Microsoft Windows starting from Windows 2000, up to Windows 7. This setup is designed for administrators wishing to take remote control of a remote box, in a secure manner, for any network that is used.
