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.

As the laptop booted up, John noticed something peculiar. The login screen looked different. Instead of the usual Windows 10 logo, he saw a stylized "Windows X-Lite" logo, accompanied by a version number: "19045.3757". A quick glance at the system properties confirmed his suspicions: someone - or something - had replaced the original Windows 10 installation with a custom, lightweight variant.

of disk space when installed, with the ISO file typically being under 1.5 GB. Resource Efficiency : Idles as low as 0.4 GB – 0.6 GB Process Count : Stripped down to roughly 30–45 background processes , compared to 150+ in a standard Windows install. Primary Enhancements

In the fast-paced world of technology, aging hardware often gets left behind. As Windows 10 and 11 become increasingly bloated with features, background processes, and telemetries, older computers—particularly those running 32-bit (x86) architectures—begin to stutter, lag, and become frustratingly slow. Enter the project, a specialized, highly optimized, and stripped-down custom build designed to breathe new life into legacy hardware.

Includes essential framework support (DirectX, .NET) without the background overhead that causes lag. What’s Removed? As the laptop booted up, John noticed something peculiar

: Common in X-Lite builds are "Extras" folders on the desktop that allow you to easily re-install the Microsoft Store or web browsers like Chrome and Firefox, as they aren't included by default. Performance vs. Functionality

Windows X-Lite –19045.3757– Micro 10 SE –x86 proves that Windows 10 can still run on hardware from 2006. Just remember: with great reduction comes great responsibility. Secure it behind a hardware firewall, keep it offline for sensitive work, and always back up your data.

To achieve its "Micro" status, several non-essential Windows features have been removed or disabled: A Competitor to Tiny10? - X-Lite Optimum 10 Classic A quick glance at the system properties confirmed

Reviewers generally categorize Windows X-Lite as an "excellent" lightweight project for enthusiasts reviving old hardware . However, security experts on forums like Reddit and guru3D strongly advise against using it as a "daily driver" for sensitive tasks like banking or professional work due to the inherent risks of modified operating systems .

If you need a more customized experience, you might also consider looking at other specialized editions on the X-Lite website to see if they fit your specific needs. Share public link

OTR library and toolkit

This is the portable OTR Messaging Library, as well as the toolkit to help you forge messages. You need this library in order to use the other OTR software on this page. [Note that some binary packages, particularly Windows, do not have a separate library package, but just include the library and toolkit in the packages below.] The current version is 4.1.1.

Java OTR library

This is the Java version of the OTR library. This is for developers of Java applications that want to add support for OTR. End users do not require this package. It's still early days, but you can download java-otr version 0.1.0 (sig).

OTR plugin for Pidgin

This is a plugin for Pidgin 2.x which implements Off-the-Record Messaging over any IM network Pidgin supports. The current version is 4.0.2.

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.

Source Code Repository and Bugtracker

You can find a git repository of the OTR source code, as well as the bugtracker, on the otr.im community development site:

Mailing Lists

If you use OTR software, you should join at least the otr-announce mailing list, and possibly otr-users (for users of OTR software) or otr-dev (for developers of OTR software) as well.

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).
