pwd_controlaula — create a file with a VNC encrypted password
pwd_controlaula passwd-file passwd
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
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.
This program has these mandatory arguments:
passwd-file file where the encrypted password for vncserver use.
passwd plain text password to be encrypted.
