Beam Messenger

Beam is a secure chat application that ensures private communications between parties. The purpose of Beam Messenger is to provide a free and open source blueprint for anyone who is interested with working with encrypted communication. Using SSL/TLS, messages are able to be securely sent between two separate parties ensuring private communications. Currently only non-local communication is possible over the same network.
