# pwd\_controlaula(8)

create a file with a VNC encrypted password

## NAME

pwd\_controlaula — create a file with a VNC encrypted password

## SYNOPSIS

**pwd\_controlaula** passwd-file passwd

## DESCRIPTION

**pwd\_controlaula** allows you to set the password used to access VNC desktops.  It stores an obfuscated version of the given  **passwd** in the given **passwd-file** file. So, a vnc server will be able to start with the -passwd command using the given password.

This small application is based on the **vncpasswd** from the vnc4-common Debian package.

The password must be at least six characters long, and only the first eight characters are significant.  Note that the stored password is **not** encrypted securely - anyone who has access to this file can trivially find out the plaintext password.  However, when accessing a VNC desktop a challenge-response mechanism is used over the wire making it hard for anyone to crack the password simply by snooping on the network.

## OPTIONS

This program has these mandatory arguments:

- *passwd-file* file where the encrypted password for vncserver use.

  - *passwd* plain text password to be encrypted.
