PsiphonOverMITM is a Windows tool written in PowerShell that helps Psiphon, a censorship-circumvention VPN used in countries with internet restrictions, connect to its network via a technique called MITM-DomainFronting. The readme is written in Farsi (Persian), suggesting it is primarily aimed at users in Iran or other regions with internet censorship. The architecture works like this: instead of Psiphon connecting directly to its network (which can be blocked), it routes its connection through a local proxy running Xray (an open-source traffic routing tool) on your computer. Xray intercepts the TLS traffic using a locally generated self-signed certificate, then forwards it through domain fronting routes via CDN providers like Akamai and Fastly, which are harder for censors to block. The tool includes a simple Start/Stop/Status menu, automatic certificate generation, and step-by-step logs of each stage. Setup requires running the launcher as Administrator on Windows 10 or 11 (to install the certificate into Windows' trusted certificate store and manage ports), then configuring Psiphon to use localhost port 20808 as its upstream proxy. The project credits its core MITM-DomainFronting configuration to a separate project called Patterniha.
