Get a secure, peer-to-peer instant messenger
One messenger for Internet and LAN chat with end-to-end encryption
Version 220.127.116.11 (alpha)
Technitium Bit Chat is a secure, 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 strong cryptography. It can be used over Internet and private LAN networks for instant messaging and file transfer.
The architecture is designed keeping in mind the security principle that everybody is secure or no one is. There is no meta data generated when you use Bit Chat. The only thing that we know, is the email address of the user who registered for a digital certificate. The digital certificate tells that the email address was verified, which is similar to, in concept, to any domain validated SSL certificates issued to websites.

Why Is Privacy Important?
Watch this episode of Last Week Tonight with John Oliver: Government Surveillance (HBO) in which John sits down with Edward Snowden to discuss the NSA, the balance between privacy and security, and dick-pics. You may wish to skip to 13:38 in the video to jump to the interview.
"Your rights matter because you never know when you're going to need them."
- Edward Snowden
