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 for everyone. A reference implementation of the protocol is published as free and open-source software under the terms of the GNU General Public License (GPL) version 3 or later.

History

The initial commit to GitHub was pushed on June 23, 2013, by a user named irungentoo. Pre-alpha testing binaries were made available for users from February 3, 2014, onwards, and nightly builds of Tox are published by the Jenkins Automatron. On July 12, 2014, Tox entered an alpha stage in development and a redesigned download page was created for the occasion.

Features

Users are assigned a public and private key, and they connect to each other directly in a fully distributed, peer-to-peer network. Users have the ability to message friends, join chat rooms with friends or strangers, voice/video chat, and send each other files. All traffic over Tox is end-to-end encrypted using the NaCllibrary, which provides authenticated encryption and perfect forward secrecy.

Tox clients aim to provide support for various secure and anonymised communication features; while every client supports messaging, features like group messaging, voice and video calling, voice and video conferencing, typing indicators, message read-receipts, file sharing, profile encryption, and desktop streamingare supported to various degrees by mobile and desktop clients. Additional features can be implemented by any client as long as they are supported by the core protocol. Features that are not related to the core networking system are left up to the client. Client developers are strongly encouraged to adhere to the Tox Client Standard in order to maintain cross-client compatibility and uphold best security practices.

Tox是一个使用端到端加密法及点对点网络的即时通讯和视频电话协议，遵循GNU通用公共许可证协议发布。该项目的目标是为所有人提供安全而方便的通信方式。此协议的一个参考实现已作为自由及开放源代码软件发布。

历史[编辑]

2013年6月23日Tox原始代码由用户irungentoo托管于GitHub上。2014年2月3日，可供用户测试使用的技术预览版二进制文件发布，此后的nightly版本通过Jenkins Automatron发布[3]。2014年7月12日，Tox的开发进入了alpha阶段，网站的下载页面也被重新设计公布。

特点[编辑]

Tox用户将会分配到一个公钥和一个私钥，之后直接通过一个分布式对等网络互相连接。用户可以通过Tox给朋友发送信息、语音或进行视频聊天，群聊或发送文件。所有通过Tox的流量将使用NaCl进行端到端加密。

qTox、µTox等Tox客户端设计提供及时通讯、群聊、语音及视频通话、语音及视频会议、文件加密共享、正在输入提示、已阅提示、远程桌面演示。任何使用Tox协议的不同客户端之间可以互相通讯。与协议无关功能限制于各客户端的开发。开发方强烈建议各客户端开发人员坚持使用标准Tox协议，以保正各客户端之间的兼容性和安全性。
