Cloak is not a standalone proxy program. Rather, it works by masquerading proxied traffic as normal web browsing activities. In contrast to traditional tools which have very prominent traffic fingerprints and can be blocked by simple filtering rules, it's very difficult to precisely target Cloak with little false positives. This increases the collateral damage to censorship actions as attempts to block Cloak could also damage services the censor state relies on. To any third party observer, a host running Cloak server is indistinguishable from an innocent web server. Both while passively observing traffic flow to and from the server, as well as while actively probing the behaviours of a Cloak server. This is achieved through the use a series of cryptographic steganography techniques. Cloak can be used in conjunction with any proxy program that tunnels traffic through TCP or UDP, such as Shadowsocks, OpenVPN and Tor. Multiple proxy servers can be running on the same server host and Cloak server will act as a reverse proxy, bridging clients with their desired proxy end. Cloak multiplexes traffic through multiple underlying TCP connections which reduces head-of-line blocking and eliminates TCP handshake overhead. This also makes the traffic pattern more similar to real websites. Cloak provides multi-user support, allowing multiple clients t","default_branch":null,"files":null,"tree":[],"storefront":"/r/cbeuw","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/cbeuw/Cloak/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
