SHA-1 hasn’t been considered a secure cryptographic solution against well-funded opponents for years, but it is still valid as a data consistency check to ensure that the file you have has not been tampered with. To avoid that, the Psiphon team maintains a list of SHA-1 hashes that can be used to verify that the Psiphon client you’ve downloaded is valid.

I asked the Psiphon folks how the protocol selection worked and received this response:īoth the Android and Windows clients automatically select the best transport protocol to use to connect to a Psiphon server. Psiphon clients are current available for Windows and Android and connect to the Psiphon network through a variety of transport protocols.
Governments or other organizations attempting to censor the internet will try to detect circumvention methods like VPNs and proxies, which is what Psiphon seeks to avoid. Psiphon’s main aim is to hide the fact that it is being used at all. Even the TOR browser is easily detected by ISPs and can draw unwanted attention. There are obfuscation techniques that can be used such as Obfsproxy, or even just putting and OpenVPN server on port 443 goes a long way to hiding it within normal HTTPS traffic.

Psiphon is a tool that aims to defeat internet censorship.
