Bitmessage
|
Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It also aims to hide "non-content" data, like the sender and receiver of messages, from eavesdroppers. If Bitmessage is completely new to you, you may wish to start by reading the whitepaper.
Download
An open source client, PyBitmessage, is available for free under the very liberal MIT license.
Download for Windows

Security Warning
The RSA cryptographic library currently used by the Bitmessage client is not well-reviewed and probably contains cryptographic failings. Therefore, Bitmessage should be considered a proof-of-concept until it can be upgraded to use Elliptic Curve Cryptography. We are working on the upgrade and it is almost complete.
Source code
You may view the Python source code on Github. PyBitmessage requires PyQt. Step-by-step instructions on how to run the source code on Windows is available here.
PyBitmessage should run on any OS though it is only lightly tested on Ubuntu and OSX. The start-on-boot and minimize-to-tray features are only implemented for Windows thus far.
Forum
A community-based forum for questions, feedback, and discussion is available at Bitmessage.org/forum.
