How to configure and use encryption with SC SingleClick ?

Post by redge »

A quick rundown script for using UltraVNC SC with encryption could currently (UltraVNC 1.0.0) be (applicable for UltraVNC 1.0.0 to 1.0.4)
  • 1. Download msrc4plugin version 1.2.2 , already renamed as msrc4plugin.dsm
  • 2. Download UltraVNC viewer
  • 3. Copy file msrc4plugin.dsm to directory where UltraVNC Viewer was installed
    (default copy to %programfiles\UltraVNC, don't copy to plugin folder).
  • 4. Start UltraVNC Viewer, select msrc4plugin.dsm in the dropdown list and check "Use DSM Plugin".
    Click the config button and then Click the "Gen Key" button, close the viewer.
    A file named new_rc4.key should be created in the directory where UltraVNC Viewer is installed. (not inside plugin folder)
    Rename new_rc4.key to rc4.key.
  • 5. Download custom.zip
    Extract it to a directory and copy msrc4plugin.dsm and rc4.key to this directory.

    Follow the instructions to customize your version and upload it using:
    http://www.uvnc.com/pchelpware/creator/index.html (creator).
    use UltraVncSC based on RC23

copy rc4.key exactly same filename/content for SingleClick and vncviewer

When SC creation done available on your own website or transmitted with instant messenger or e-mail, to person(s) need assistance.

A. helper (yourself)

Prerequired for encryption plugin for vncviewer:
the msrc4plugin.dsm need to be on same folder of vncviewer and not inside subfolder plugin
  • Launch the viewer from Start... Run...
    "%programfiles%\UltraVNC\vncviewer.exe" -dsmplugin msrc4plugin.dsm -listen 5500
    other example:
    d:\mydrive\vncviewer.exe -dsmplugin msrc4plugin.dsm -listen 5500

    (with dsmplugin, not possible to start vncviewer as listen from menu)
    only possible from command line or create your own shortcut with above example.
    modify the target shorcut for the listening icon
    "C:\Program Files\UltraVNC\vncviewer.exe" -listen

    to "C:\Program Files\UltraVNC\vncviewer.exe" -dsmplugin msrc4plugin.dsm -listen 5500

    --- without UltraVNC Repeater ---
    helper had a NAT router, need open port 5500 and redirect then to your own local pc as as example
B. Person need assistance, support, help.
  • launch UltraVNC SC and doubleclick connection wait fews seconds...
A.helper (yourself) again
  • you can seen a question:
    Accept or refuse incoming connection from the person started UltraVNC SC
  • When your are connected togueter,
    Clicking "Show Status Window" in UltraVNC Viewer
    should reveal a window stating a line like:
    "Status: Connected(MS RC4 NoReg Plugin-v1.2.2.0)"
    indicating that the plugin is actually in use.

(a little bit modified ;-)) thank you very well to her.
