The VNC Password Decoder (vncpwd) tool by Luigi Auriemma can decrypt classic VNC DES encryption method. Simply embed the encrypted password after the command line tool and the real password will be displayed. To use vncpwd, click Start button, type cmd at search bar and press Enter. Oct 15, 2010 For an automated installation project at work I needed to set the password to an UltraVNC server running on Windows. VNC is a remote desktop protocol and very handy.For good reason the server's password is not stored in the clear, but rather a (now weakly) encrypted version.
NAME
vncpasswd− change the VNC password
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.
OPTIONS
−f | Filter mode. Read a plain-textpassword from stdin and write an encrypted version tostdout. Note that in filter mode, short or even emptypasswords will be silently accepted. |
A view-onlypassword must be separated from the normal password by anewline character.

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.
