A peer-topeer anonymous and secure private messenger that uses Tor. It is also open-source software that allows users to modify it and re-distribute it under the GNU General Public License version 3. Anonymous Messenger uses Tor as its anonymity network, and data transport security, using the onion protocol v3. It can be run on any device, and users can connect directly anonymously, without the need to set up servers. Also, it uses the Signal protocol to encrypt data before sending it directly over the Tor network to the intended recipient, meaning we get two layers end-to-end without using any service or server.
