Tungsten Crypto library

What is Tungsten?

Tungsten is a messaging application for encrypted and anonymous communication with other users.

You can get the application:

All text messages and data sent via Tungsten are end-to-end encrypted. Tungsten uses its own protocol, with support for offline messaging, multi-device setups as well as group messaging. All encrypted communication is synchronised between all of the users devices.

Tungsten allows users to create multiple identities to keep their conversations organized. With multiple identities, users can easily manage who can reach them without compromising the user’s personal information or mixing up context.

Tungsten offers an easy way to set up another device with a complete history of existing conversations. It requires physical access to both devices, which adds an additional level of security.
