Barrier on GitHub - User-maintained fork of Synergy 1.Overall Opinion: Decent software, very convenient to use when working with multiple computers.Synergy Core on GitHub - Official source code.^ 'Cracking Synergy's Bad Cryptography'.^ 'Synergy: Integer Overflow, Key Reuse, IV Reuse'.

^ 'First committed version of main.cpp'.In said discussion, Chris Schoeneman (the creator of Synergy) stated that instead of supporting a 1.3.x team, he intends on releasing version 2.0 of Synergy, and publicly announced on that he has been making progress on this version. There was never official confirmation that the original Synergy project had been abandoned however, there was public discussion providing speculation. The original version of Synergy had not been updated for a notable length of time (as of 6 June 2010, the latest release was 2 April 2006). Synergy+ was created in 2009 as a maintenance fork for the purpose of fixing bugs inherited from the original version. It provides most of the features of the original and adds a few improvements. Synergy is a from-scratch reimplementation of CosmoSynergy. CosmoSynergy was a great success but Cosmo Software declined to productize it and the company was later closed. They wrote it, and Chris Schoeneman contributed, to solve a problem: most of the engineers in Cosmo Software had both an Irix and a Windows box on their desks and switchboxes were expensive and annoying. The first incarnation of Synergy was CosmoSynergy, created by Richard Lee and Adam Feder then at Cosmo Software, Inc., a subsidiary of SGI (née Silicon Graphics, Inc.), at the end of 1996. TCP/IP communications ( default port 24800 ) are used to send mouse, keyboard and clipboard events between computers in Synergy 1. In July 2013 the Defuse Security Group reported the proprietary encryption used in Synergy 1.6 to be insecure and released an exploit which could be used to passively decrypt the commands sent to the Synergy 1.6 clients. This previously required the purchase of the Pro edition in version 1. The keyboard and mouse are connected to the server machine.Īs of version 2.0 (2017) keystrokes, mouse movements and clipboard contents are sent via an encrypted SSL network connection. The program is implemented as a server which defines which screen-edges lead to which machines, and one or more clients, which connect to the server to offer the use of their desktops. The clipboard and even screensavers can be synchronized. This makes it possible to control several machines as easily as if they were a single multi-monitor computer. Key presses will be delivered to whichever computer the mouse-pointer is located in. Once the program is installed, users can move the mouse 'off' the side of their desktop on one computer, and the mouse pointer will appear on the desktop of another computer.
