This year Chinese government deepened a attack on virtual private networks (VPNs)-tools that help internet users in the mainland get the open, uncensored interweb. Although it is not a blanket ban, the latest prohibitions are switching the services out of their legal grey area and additionally towards a black one. In July alone, one such made-in-China VPN surprisingly ended operations, Apple company got rid of dozens of VPN mobile apps from its China-facing iphone app store, and certain international hotels halted offering VPN services in their in-house wi-fi compatability.
However the government bodies was hitting VPN usage just before the most recent push. From the moment president Xi Jinping took office in the year 2012, activating a VPN in China has developed into a repeated pain - speeds are slow, and online connectivity frequently drops. Especially before important politics events (like this year's upcoming party congress in October), it's typical for connections to discontinue quickly, or not even form at all.
In response to such situations, China's tech-savvy computer programmers have already been using a different, lesser-known program to connect to the wide open world wide web. It's referred to as Shadowsocks, and it's an open-source proxy designed for the certain intention of jumping Chinese Great Firewall. Whilst the government has made an attempt to curb its distribution, it is more likely to remain tough to decrease.
How's Shadowsocks not the same as a VPN?
To realize how Shadowsocks works, we'll have to get somewhat into the cyberweeds. Shadowsocks depends upon a technique generally known as proxying. Proxying grew sought after in China during the early days of the Great Firewall - before it was truly "great." In this setup, before connecting to the wider internet, you first connect to a computer other than your own. This other computer is termed a "proxy server." When you use a proxy, your complete traffic is re-routed first through the proxy server, which can be located virtually any place. So regardless of if you're in China, your proxy server in Australia can readily get connected to Google, Facebook, and the like.
Nevertheless, the Great Firewall has since grown more powerful. Currently, even if you have a proxy server in Australia, the Great Firewall can certainly identify and stop traffic it doesn't like from that server. It still understands you're asking for packets from Google-you're just using a bit of an odd route for it. That's where Shadowsocks comes in. It creates an encrypted link between the Shadowsocks client on your local personal computer and the one running on your proxy server, using an open-source internet protocol often called SOCKS5.
How is this not the same as a VPN? VPNs also perform the job by re-routing and encrypting data. Butmost people who use them in China use one of several big providers. That means it is easy for the governing administration to detect those service providers and then prohibit traffic from them. And VPNs often depend upon one of several famous internet protocols, which tell computer systems the way to talk with one another over the web. Chinese censors have been able to utilize machine learning to locate "fingerprints" that distinguish traffic from VPNs utilizing these protocols.

These methods don't succeed so well on Shadowsocks, because it's a much less centralized system.
Each and every Shadowsocks user builds his own proxy connection, and as a result each one looks a little not the same as the outside. For that reason, finding this traffic is more difficult for the Great Firewall-that is to say, through Shadowsocks, it is quite tough for the firewall to separate traffic driving to an innocuous music video or a financial report article from traffic visiting Google or some other site blacklisted in China.
Leo Weese, a Hong Kong-based privacy follower, likens VPNs to a quality freight forwarder, and Shadowsocks to having a package mailed to a mate who next re-addresses the item to the real intended receiver before putting it back in the mail. The first approach is much more worthwhile as a business venture, but less difficult for govt to diagnose and closed. The 2nd is make shift, but much more unseen.
Further, tech-savvy Shadowsocks owners normally customize their settings, so that it is even harder for the Great Firewall to detect them.
"People use VPNs to build up inter-company links, to set up a safe network. It wasn't suitable for the circumvention of content censorship," says Larry Salibra, a Hong Kong-based privacy follower. With Shadowsocks, he adds, "Everyone can certainly set up it to look like their own thing. Doing this everybody's not using the same protocol."
Calling all programmers
However, if you're a luddite, you'll perhaps have difficulty setting up Shadowsocks. One general way to make use of it demands renting out a virtual private server (VPS) placed outside of China and perfect for using Shadowsocks. Next users must log in to the server using their computer's terminal, and enter the Shadowsocks code. Next, using a Shadowsocks client app (there are many, both free and paid), users enter the server Internet protocol address and password and access the server. After that, they could glance the internet openly.
Shadowsocks is oftentimes tough to use since it originated as a for-coders, by-coders software. The software initially reached people in the year 2012 through Github, when a coder using the pseudonym "Clowwindy" uploaded it to the code repository. Word-of-mouth spread among other Chinese coders, and additionally on Tweets, which has really been a place for contra-firewall Chinese programmers. A online community established around Shadowsocks. Staff at several world's greatest technology firms-both Chinese and international-team up in their leisure time to manage the software's code. Coders have created third-party apps to run it, each touting several unique options.
"Shadowsocks is an excellent formation...- Until recently, there is still no proof that it can be recognized and become ceased by the GFW."
One engineer is the author behind Potatso, a Shadowsocks client for The apple company iOS. Operating out of Suzhou, China and working at a US-based software enterprise, he felt annoyed at the firewall's block on Google and Github (the 2nd is blocked from time to time), each of which he counted on to code for job. He created Potatso during nights and weekends out of frustration with other Shadowsocks clients, and consequently put it in the app store.
"Shadowsocks is an ideal invention," he says, requiring to stay confidential. "Until now, there's still no signs that it could be identified and be stopped by the GFW."
Shadowsocks may not be the "perfect weapon" to overcome the GFW for ever. But it'll certainly lurk in the dark for a time.
