NAME
vncpasswd− change the VNC password
Enter your password when prompted. If you would like to enter a view-only password respond accordingly for your specific setup. In my case I did not want to set up a view-only password. Now that you have your passwd file you can use it to connect to your VNC server. VNC password ('VNC viewers may control screen with password') Whenever the built-in Screen Sharing client (Cmd+K in Finder) connects to a Screen Sharing server, it uses only types 1, 2 and 3. Then server enables traffic encryption that may work in one of two modes: full encryption or keystroke/mouse move encryption.
SYNOPSIS
vncpasswd[passwd-file]
vncpasswd −f
DESCRIPTION
vncpasswdallows you to set the password used to access VNC desktops.Its default behavior is to prompt for a VNC password andthen store an obfuscated version of this password topasswd-file (or to $HOME/.vnc/passwd if no passwordfile is specified.) The vncserver script runsvncpasswd the first time you start a VNC desktop, andit invokes Xvnc with the appropriate−rfbauth option. vncviewer can also begiven a password file to use via the −passwdoption.
The passwordmust be at least six characters long (unless the−f command-line option is used-- see below),and only the first eight characters are significant. Notethat the stored password is not encrypted securely -anyone who has access to this file can trivially find outthe plain-text password, so vncpasswd always setsappropriate permissions (read and write only by the owner.)However, when accessing a VNC desktop, a challenge-responsemechanism is used over the wire making it hard for anyone tocrack the password simply by snooping on the network.

VNC wasoriginally developed by the RealVNC team while at OlivettiResearch Ltd / AT&T Laboratories Cambridge. TightVNCadditions were implemented by Constantin Kaplinsky. Manyother people have since participated in development, testingand support. This manual is part of the TigerVNC softwaresuite.
I'm looking around here, trying to find a way to change the key that VNC uses to encrypt passwords. Supposedly, the key is always the same, and it's widely known, making it easier for someone to brute-force attack, or possibly to sniff out and de-crypt a password. At work, we also recently had a security audit, and although it wasn't high up on the list, VNC was listed as being vulnerable for that same reason... the encryption key is always the same.
So, I'm trying to find out if there is a way to change that key and reset all my passwords. I have Windows and Linux systems, so I need to try and find out how to do this for both platforms.
Anyone heard of this, or know how to go about doing it?
Thanks...
