This utility will allow you to fetch and decrypt VNC passwords on a local computer system with VNC Server configured with a password.
It works by fetching the encrypted password in the registry then decrypting it using the DES algorithm.

The utlity has two sections, Automatic Password Decrpytion and Custom Password Decryption. The automatic section will retrieve the encrypted password from the registry and decrypt it, the custom section will allow you to decrypt an encrypted password found on another computer through accesing the registry keys.
