How to change encryption key?

[Brandon Laing]

Hey list,

I am currently running VNC on a number if different systems, both Windows based and Linux based. As many of these systems contain sensitive data, I'm looking to make them as secure as possible, while still keeping VNC on them. However, from what I've read, VNC uses the same key to encrypt all passwords, and that this key is easily obtainable, making it relatively easy to decrypt the password if someone happens to sniff it out in encrypted form. So, what I'd like to do is change the key used to encrypt passwords, and then set up the passwords on these systems again. Trouble is... I haven't had any luck finding out how to do this. Can anyone enlighten me on this? Ideally, I'd like to do it to all machines and both platforms.

Thank you,
Brandon
