One messenger for Internet and LAN chat with end-to-end encryption

Version 1.1 (alpha)
Technitium Mesh is a secure, anonymous, peer-to-peer (p2p), open source instant messenger designed to provide end-to-end encryption. Primary aim of developing this instant messenger is to provide privacy which is achieved using cryptography and anonymity using Tor network. It can be used over Internet and private LAN networks (without Internet) for instant messaging and file transfer with support for private chats and group chats.
Mesh is based on Bit Chat and is its successor. Mesh takes core ideas from its predecessor and removes a few. Notably, Mesh does not require centralized user registration and provides anonymous profile support using Tor hidden service. It also removes use of BitTorrent trackers for finding peers which was causing issues with Bit Chat since some ISPs blocking BitTorrent traffic would also block Bit Chat traffic. Instead, Mesh relies only on Distributed Hash Tables (DHT) for all purposes.
Mesh allows creating both pure p2p and anonymous profiles with support for running multiple profiles concurrently. Both p2p and anonymous profiles are interoperable such that a p2p profile user can connect with an anonymous profile user via Tor Network.
With Mesh, there is no meta data generated. User identifier is designed in such a way that it can be changed anytime to hide identity. Since, there is no user registration, we don't know who uses Mesh or how many people use it. In p2p mode, the connections use IPv4 or IPv6 connectivity directly to connect with peers without any server in between. With anonymous mode, all connectivity occurs over Tor network and uses Tor hidden service to accept inbound connections.

Why Is Privacy Important?

OfficeSIP Messenger is based on industry-standard libraries used by Microsoft Office Communicator, providing robust, reliable operation in business environment. Thanks to the high-quality code, OfficeSIP Messenger ensures the highest level of compatibility with audio clients and Web cameras, and provides landline-quality calling for both voice and video.
Unlike other enterprise instant messengers and communicators, OfficeSIP Messenger is entirely server-based, allowing administrators to enter, store and modify all settings, configurations, and user profiles on a corporate server. IM users will benefit from a single sign-on after logging in to the corporate domain. Active Directory support allows the IM system getting information about the users directly from the server?s domain controller.

The free enterprise communicator costs nothing, yet provides the level of services not found in its much more expensive competitors. Voice communications are implemented via VoIP using the industry-standard SIP protocol to provide free voice calling no matter whether the recipients are in the same building or on the other side of the world. Single log-on allows softphone users signing in to a SIP server without having to enter a password. The free enterprise instant messenger offers businesses advanced video chat capabilities with easy installation and zero-hassle NAT/firewall traversal.
Most offices are using a single Internet uplink to connect with the world. Sharing a single Internet connection means that a NAT router is often in place. Combined with a firewall, the router can prevent many voice communicators from streaming audio and video. OfficeSIP Messenger implements ICE, STUN, and TURN protocols to easily traverse NAT and firewalls with no additional configuration required on either side. TLS support ensures that all communications are securely encrypted, and cannot be intercepted by a third party.
