ricochet-im/ricochet: Anonymous peer-to-peer instant messaging

Ricochet is an anonymous peer-to-peer instant messaging system that doesn't trust anyone with your identity, contact list, or communications. It operates without exposing your IP address, metadata, or relying on central servers, using Tor Network hidden services. Ricochet is experimental, cross-platform, and open-source, available for Windows, OS X, and Linux.
