Password encryption algorithm

What is the algorithm used for encrypting the password in the registry ?

I am thinking over a way to setup UltraVNC with a specific password, eventually chosen by the user during install. Any hint is welcome.

Regards,

Ronan

P.S. : I know the answer is in the code, but I am not a C++ guru (yet). Any hint is welcome.

Create a passwd local
export the specific key from the registry
during installation import the key back...add it ot
the default regs file

export and inport registry, no c needed

Rudi, thank you for your answer (this is how I do for now), but I would like the user to input its own password during the setup.

Any idea here ?

Wait, you want the user to set the pass?
Whats wrong with the setup now, where after installing, it brings up the config box and wants you to enter the password?

I would like a one click install where the user does not enter into UltraVNC parameters. I still want him to set the password so that he still has the control.

The password is encrypted using DES. You will probably need to make a plugin or DLL for your installer to do this, since most installer scripting languages would be hard pressed to implement DES.

See: winvnc/d3des.c, winvnc/vncpasswd.h for the related source code.
