5 Best Free and Open Source Tox Clients

Tox is a peer-to-peer instant-messaging and video-calling protocol that offers end-to-end encryption. The stated goal of the project is to provide secure yet easily accessible communication.

The Tox core is a library establishing the protocol and API. User front-ends, or clients, are built on the top of the core. Anyone can create a client utilizing the core. Tox uses the cryptographic primitives present in the NaCl crypto library, via libsodium. Specifically, Tox employs Curve25519 for its key exchanges, xsalsa20 for symmetric encryption, and Poly1305 for MACs.

Tox is licensed under the GNU General Public Licence 3.0.
