What OS's are you running on? I may be able to help you. I took the vnc password source and put it into a separate app with registry access. It allows you to read and write passwords on the local and remote machines. However, I have only tested it on NT 4.0 -> NT 4.0 scenario's.

What I'm after, though, is to encrypt a text password so that it can be put into the registry on the fly. Currently it's a pain in the rear to do batch updates to Windows VNC server passwords since you have to set up the password on the system, then export it to a plain-text REG file. Even worse, you then have the text representation of the binary password sitting in a file somewhere - and someone else can easily come along and decrypt it. ----- Original Message ----- From: "Sharma, Shashi" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, 2002-04-19 11:50 Subject: RE: vncpasswd for Windows > I dont think you can get the cleartext from the password. > The file which does the job of authenticating is d3des.c file in the source > code. > > The way it works on the vnc is > server sends a challenge to client ->16 bytes > client reads the challenget and then encyrpt it with the password > and send back the response. > Server knows the challenge it sent and then compare it with what it expects > > > > -----Original Message----- > From: Alex K.
