adding a winvnc switch to return a winvnc-encrypted password

wouldn't it be useful if ultravnc server had a switch that just had the program returning an encrypted winvnc password?

It would be useful to set up a password during the install process: one could just do a script that asks the user for a password and then runs winvnc.exe > dumpfile.txt to obtain a password that could be written in the registry.

Naturally launching winvnc.exe with that switch should not start the winvnc server, only have the program print out the encrypted string and then exit.

That would add just a few hundred bytes to the application executable and would save a lot of users from making their own utility to convert a password to an encrypted password to store in the registry.

is it ok if I make the patch and upload it somewhere? is there ultravnc developer willing to integrate it in ultravnc sources?

hellooo?? did at least somebody understand what i'm talking about? winvnc stores its incoming connections password in an encrypted form inside the registry. I wanted to know if it was possible to add a switch that returns a password encrypted with the same algorithm.

I'm using a very customizable setup (createinstall) and I wanted to add a setup page to configure the winvnc incoming connections password directly from the setup without having the users to open winvnc properties.

Can one of the author please answer when seeing this post? thanks.
(if authors don't have time to make it but they think it's a good idea to add that feature I can make the changes in the winvnc sources and post them somewherE)

I think I understand what you're talking about.
But I don't think it's very helpful.
Everybody can configure it and then grab it from the registry.

If you want to build a setup without starting winvnc, rip out the encryption part from the code and build a standalone utility EncryptPasswd.exe.

yes i could make an utility for that however i think that such feature would be useful for everybody that's why i posted it here. When somebody creates a deployable setup package with a .reg file that configures winvnc he still has to change the passwords by hand after installation for added security, with such winvnc switch one could create a setup that asks the user a password and launches winvnc to obtain the encrypted password to write in the registry without need of other utilities.

Also you should consider most of the people configure just the password after installing vnc (it's the only thing that doesn't have a default value) so a tab page to set the password during the setup could make the configuration easier for first-time users.
