Off-the-Record (OTR) Messaging allows you to have private conversations over instant messaging by providing:

Encryption
No one else can read your instant messages.
Authentication
You are assured the correspondent is who you think it is.
Deniability
The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified.
Perfect forward secrecy
If you lose control of your private keys, no previous conversation is compromised.

VCDS 20.4.2 is a legacy version of the VAG-COM Diagnostic System software used for diagnosing Volkswagen Group vehicles. While the software itself is free to download from the official Ross-Tech site, it requires a genuine Ross-Tech interface (cable) to function, as the license is built directly into the hardware. Critical Installation Warnings

Version Obsolescence: Release 20.4 is no longer supported; users are strongly encouraged to update to the current version (e.g., Release 25.3.1) for better compatibility with newer vehicles.

Third-Party Cables: If you are using a non-genuine "clone" cable, be aware that official software updates can permanently block or "brick" these cables. Step-by-Step Installation Guide VCDS 20.4 Installation Guide | PDF - Scribd

Searching for a "free download" of VCDS (Volkswagen City Diagnostic System) version 20.4.2 often leads to unauthorized or "cracked" versions of the software. It is important to note that VCDS is proprietary software developed by Ross-Tech, and using unofficial links can expose your computer to malware or damage your vehicle's electronic control units (ECUs). Official Download and Installation

The safest way to get VCDS is directly from the manufacturer. Ross-Tech provides the software for free to those who own an authentic Ross-Tech interface (like the HEX-V2 or HEX-NET).

Version Compatibility: Version 20.4.2 is an older release. Ross-Tech typically encourages users to use the most current version (currently in the 23.x or 24.x range) to ensure compatibility with newer vehicles and bug fixes. Installation Steps:

Download the executable installer (VCDS-Release-XX.X.X-Installer.exe). Run the installer and follow the on-screen prompts. Connect your authentic interface to the USB port.

Open VCDS and go to Options > Test to confirm the software recognizes the cable. Risks of Unofficial "39link" Downloads

Links labeled as "39link" or similar "free" cracks usually involve: Malware: Installers may contain trojans or keyloggers.

Hardware Lock: Many unauthorized versions require a specific "loader" that can permanently brick your interface if it detects an internet connection or an update. VCDS 20

Incomplete Data: Cracked versions often lack full label files, meaning you won't see descriptions for many diagnostic codes or adaptation channels.

OTR localhost AIM proxy

This software is no longer supported. Please use an IM client with native support for OTR.

This is a localhost proxy you can use with almost any AIM client in order to participate in Off-the-Record conversations. The current version is 0.3.1, which means it's still a long way from done. Read the README file carefully. Some things it's still missing:

But it should work for most people. Please send feedback to the otr-users mailing list, or to . You may need the above library packages.

About OTR

Here are some documents and papers describing OTR. The CodeCon presentation is quite useful to get started.

Frequently Asked Questions

What implementations of Off-the-Record Messaging are there?
Please see our OTR-enabled software page. The OTR functionality is separated into the Off-the-Record Messaging Library (libotr), which is an LGPL-licensed library that can be used to (hopefully) easily produce OTR plugins for other IM software, or for other applications entirely.
What is the license for the OTR software?
The Off-the-Record Messaging Library is licensed under version 2.1 of the GNU Lesser General Public License. The Off-the-Record Toolkit, the pidgin-otr plugin, and the OTR proxy are licensed under version 2 of the GNU General Public License.
How is this different from the pidgin-encryption plugin?
The pidgin-encryption plugin provides encryption and authentication, but not deniability or perfect forward secrecy. If an attacker or a virus gets access to your machine, all of your past pidgin-encryption conversations are retroactively compromised. Further, since all of the messages are digitally signed, there is difficult-to-deny proof that you said what you did: not what we want for a supposedly private conversation!
How is this different from Trillian's SecureIM?
SecureIM doesn't provide any kind of authentication at all! You really have no idea (in any kind of secure way) to whom you're speaking, or if there is a "man in the middle" reading all of your messages.
How is this different from SILC?
SILC uses a completely separate network of servers and underlying network protocol. In some environments, such as firewalled or corporate setups, where a local proprietary IM protocol may be in use, SILC may not be available. Further, in its normal mode of operation, all SILC messages are shared with the SILC servers; if you want to send messages that can only be read by the person with whom you're communicating, you need to either (1) arrange a pre-shared secret in advance (which hampers perfect forward secrecy), or (2) be able to do a direct peer-to-peer connection to the other person's client, in order to do a key agreement (which may not be possible in a NAT or firewall situation).
