This summer Chinese government deepened a crackdown on virtual private networks (VPNs)-programs that assist web surfers within the mainland get the open, uncensored world-wide-web. Although it is not a blanket ban, the recent limitations are switching the services out of their lawful grey area and additionally to a black one. In July only, one such made-in-China VPN suddenly concluded operations, Apple erased dozens of VPN apps from its China-facing iphone app store, and some international hotels halted offering VPN services in their in-house wireless network.
However the government was aimed towards VPN use a long time before the latest push. From the moment president Xi Jinping took office in 2012, activating a VPN in China has become a repeated nightmare - speeds are poor, and connectivity regularly falls. Especially before key governmental events (like this year's upcoming party congress in Oct), it's not uncommon for connections to drop without delay, or not even form at all.
In response to all these conditions, Chinese tech-savvy programmers have already been counting on an extra, lesser-known software to have accessibility to the wide open net. It is often called Shadowsocks, and it's an open-source proxy designed for the certain intention of jumping Chinese GFW. Even though the government has made efforts to prevent its distribution, it is inclined to stay tough to decrease.
How is Shadowsocks distinct from a VPN?
To fully understand how Shadowsocks performs, we will have to get a bit into the cyberweeds. Shadowsocks depends upon a technique referred to proxying. Proxying turned widely used 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 firstly hook up to a computer instead of your individual. This other computer is known as a "proxy server." By using a proxy, your entire traffic is forwarded first through the proxy server, which can be positioned virtually any place. So although you are in China, your proxy server in Australia can readily get connected to Google, Facebook, etc.
Nevertheless, the Great Firewall has since grown more powerful. At present, even if you have a proxy server in Australia, the Great Firewall can identify and clog up traffic it doesn't like from that server. It still knows you're requesting packets from Google-you're just using a bit of an odd route for it. That's where Shadowsocks comes in. It builds an encrypted connection between the Shadowsocks client on your local personal computer and the one running on your proxy server, employing an open-source internet protocol named SOCKS5.
How is this distinctive from a VPN? VPNs also work by re-routing and encrypting data. Butmost of the people who use them in China use one of several major service providers. That means it is easier for the govt to discover those service providers and then obstruct traffic from them. And VPNs in most cases rely upon one of some famous internet protocols, which explain to computers how to talk to each other over the internet. Chinese censors have already been able to use machine learning to identify "fingerprints" that detect traffic from VPNs utilizing these protocols. These ways really don't succeed so well on Shadowsocks, as it is a less centralized system.

Each individual Shadowsocks user brings about his own proxy connection, hence each one looks a bit dissimilar to the outside. So, discovering this traffic is more difficult for the Great Firewall-that is to say, through Shadowsocks, it's very complicated for the firewall to separate traffic heading to an innocuous music video or a financial news article from traffic visiting Google or some other site blocked in China.
Leo Weese, a Hong Kong-based privacy promoter, likens VPNs to a professional freight forwarder, and Shadowsocks to having a package sent to a mate who then re-addresses the item to the real intended receiver before putting it back in the mail. The first method is far more rewarding as a business, but simpler and easier for authorities to diagnose and shut down. The 2nd is makeshift, but considerably more private.
Furthermore, tech-savvy Shadowsocks users normally individualize their configuration settings, turning it into even tougher for the GFW to uncover them.
"People benefit from VPNs to build inter-company links, to set up a secure network. It was not designed for the circumvention of censorship," says Larry Salibra, a Hong Kong-based privacy advocate. With Shadowsocks, he adds, "Each person can easily setup it to be like their own thing. This way everybody's not utilizing the same protocol."
Calling all of the programmers
However, if you happen to be a luddite, you may possibly have a hard time deploying Shadowsocks. One popular method to apply it requires renting out a virtual private server (VPS) placed outside of China and in a position of using Shadowsocks. Next users must log in to the server using their computer's terminal, and enter the Shadowsocks code. Following, using a Shadowsocks client software (there are a lot, both paid and free), users put in the server IP address and password and access the server. After that, they can search the internet unhampered.
Shadowsocks is commonly hard to build since it originated as a for-coders, by-coders tool. The application very first got to the general public in the year 2012 thru Github, when a designer using the pseudonym "Clowwindy" posted it to the code repository. Word-of-mouth spread among other Chinese programmers, as well as on Twitter, which has been a place for anti-firewall Chinese developers. A community formed all around Shadowsocks. People at a few of the world's greatest technology firms-both Chinese and intercontinental-work together in their spare time to maintain the software's code. Programmers have made third-party apps to make use of it, each offering different unique options.
"Shadowsocks is a remarkable invention...- Until now, there's still no proof that it can be identified and get ceased by the Great Firewall."
One particular engineer is the founder lurking behind Potatso, a Shadowsocks client for The apple company iOS. Located in Suzhou, China and working at a United-Statesbased software application business, he grew annoyed at the firewall's block on Google and Github (the second is blocked intermittently), both of which he used to code for work. He created Potatso during night time and weekends out of frustration with other Shadowsocks clients, and finally release it in the iphone app store.
"Shadowsocks is an effective invention," he says, requiring to keep anonymous. "Until now, there's still no evidence that it could be recognized and get ended by the GFW."
Shadowsocks probably are not the "flawless tool" to ruin the Great Firewall for ever. But it will likely lie in wait at night for quite a while.
