Project ToxThe project Tox developers set a goal of creating of free P2P alternative to Skype

Tox uses similar to the Skype P2P-model of interaction in the network for the dissemination of messages which use cryptographic techniques to authenticate the user and protect the transit traffic from interception. Support text messaging, voice, video and file transfer. The work is organized through a simple and typical of IM-client graphical interface.

One of the key objectives of the project is to ensure the privacy and confidentiality of correspondence, including protection from a possible traffic analysis intelligence services. For ensuring addressing of users used the distributed hash table (DHT) which organized the work in the style of BitTorrent. The communication channel has been organized by means of a superstructure over the UDP protocol with realization of session level (Lossless UDP).

For identification of each user is used the special public key which also is applied as an open key to enciphering. Separately generated private key to decrypt messages encrypted with the identity / public key. To organize the communication connection is required for the peer (each client network is a peer), which can be defined manually or automatically found (function of search of peers in a local network is available).

Tox code is written on C and licensed under the GPLv3. Supported platforms: Linux, Windows and Mac OS X. For the organization of the encryption library is used libsodium. The functionality is still in development at the level of a series of test prototypes console client written using the library ncurses, and a graphical client-based Qt5.
